- Specifically, I am aware of compilation problems with **Microsoft Visual Studio** (there even is an [issue label](https://github.com/nlohmann/json/issues?utf8=✓&q=label%3A%22visual+studio%22+) for these kind of bugs). I understand that even in 2016, complete C++11 support isn't there yet. But please also understand that I do not want to drop features or uglify the code just to make Microsoft's sub-standard compiler happy. The past has shown that there are ways to express the functionality such that the code compiles with the most recent MSVC - unfortunately, this is not the main objective of the project.
- Please refrain from proposing changes that would **break [JSON](https://json.org) conformance**. If you propose a conformant extension of JSON to be supported by the library, please motivate this extension.
- We shall not extend the library to **support comments**. There is quite some [controversy](https://www.reddit.com/r/programming/comments/4v6chu/why_json_doesnt_support_comments_douglas_crockford/) around this topic, and there were quite some [issues](https://github.com/nlohmann/json/issues/376) on this. We believe that JSON is fine without comments.
- - We do not preserve the **insertion order of object elements**. The [JSON standard](https://tools.ietf.org/html/rfc7159.html) defines objects as "an unordered collection of zero or more name/value pairs". To this end, this library does not preserve insertion order of name/value pairs. (In fact, keys will be traversed in alphabetical order as `std::map` with `std::less` is used by default.) Note this behavior conforms to the standard, and we shall not change it to any other order. If you do want to preserve the insertion order, you can specialize the object type with containers like [`tsl::ordered_map`](https://github.com/Tessil/ordered-map) or [`nlohmann::fifo_map`](https://github.com/nlohmann/fifo_map).

+## Support
-## Integration
+:question: If you have a **question**, please check if it is already answered in the [**FAQ**](https://json.nlohmann.me/home/faq/) or the [**Q&A**](https://github.com/nlohmann/json/discussions/categories/q-a) section. If not, please [**ask a new question**](https://github.com/nlohmann/json/discussions/new) there.
-[`json.hpp`](https://github.com/nlohmann/json/blob/develop/single_include/nlohmann/json.hpp) is the single required file in `single_include/nlohmann` or [released here](https://github.com/nlohmann/json/releases). You need to add
+:books: If you want to **learn more** about how to use the library, check out the rest of the [**README**](#examples), have a look at [**code examples**](https://github.com/nlohmann/json/tree/develop/doc/examples), or browse through the [**help pages**](https://json.nlohmann.me).
-```cpp
-#include <nlohmann/json.hpp>
+:construction: If you want to understand the **API** better, check out the [**API Reference**](https://json.nlohmann.me/api/basic_json/) or the [**Doxygen documentation**](https://json.nlohmann.me/doxygen/index.html).
-// for convenience
-using json = nlohmann::json;
-```
+:bug: If you found a **bug**, please check the [**FAQ**](https://json.nlohmann.me/home/faq/) if it is a known issue or the result of a design decision. Please also have a look at the [**issue list**](https://github.com/nlohmann/json/issues) before you [**create a new issue**](https://github.com/nlohmann/json/issues/new/choose). Please provide as many information as possible to help us understand and reproduce your issue.
-to the files you want to process JSON and set the necessary switches to enable C++11 (e.g., `-std=c++11` for GCC and Clang).
-
-You can further use file [`include/nlohmann/json_fwd.hpp`](https://github.com/nlohmann/json/blob/develop/include/nlohmann/json_fwd.hpp) for forward-declarations. The installation of json_fwd.hpp (as part of cmake's install step), can be achieved by setting `-DJSON_MultipleHeaders=ON`.
-
-### CMake
-
-You can also use the `nlohmann_json::nlohmann_json` interface target in CMake. This target populates the appropriate usage requirements for `INTERFACE_INCLUDE_DIRECTORIES` to point to the appropriate include directories and `INTERFACE_COMPILE_FEATURES` for the necessary C++11 flags.
-
-#### External
-
-To use this library from a CMake project, you can locate it directly with `find_package()` and use the namespaced imported target from the generated package configuration:
-
-```cmake
-# CMakeLists.txt
-find_package(nlohmann_json 3.2.0 REQUIRED)
-...
-add_library(foo ...)
-...
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-
-The package configuration file, `nlohmann_jsonConfig.cmake`, can be used either from an install tree or directly out of the build tree.
-
-#### Embedded
-
-To embed the library directly into an existing CMake project, place the entire source tree in a subdirectory and call `add_subdirectory()` in your `CMakeLists.txt` file:
-
-```cmake
-# Typically you don't care so much for a third party library's tests to be
-# run from your own project's code.
-set(JSON_BuildTests OFF CACHE INTERNAL "")
-
-# If you only include this third party in PRIVATE source files, you do not
-# need to install it when your main project gets installed.
-# set(JSON_Install OFF CACHE INTERNAL "")
-
-# Don't use include(nlohmann_json/CMakeLists.txt) since that carries with it
-# unintended consequences that will break the build. It's generally
-# discouraged (although not necessarily well documented as such) to use
-# include(...) for pulling in other CMake projects anyways.
-add_subdirectory(nlohmann_json)
-...
-add_library(foo ...)
-...
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-
-##### Embedded (FetchContent)
-
-Since CMake v3.11,
-[FetchContent](https://cmake.org/cmake/help/v3.11/module/FetchContent.html) can
-be used to automatically download the repository as a dependency at configure type.
-
-Example:
-```cmake
-include(FetchContent)
-
-FetchContent_Declare(json
- GIT_REPOSITORY https://github.com/nlohmann/json.git
- GIT_TAG v3.7.3)
-
-FetchContent_GetProperties(json)
-if(NOT json_POPULATED)
- FetchContent_Populate(json)
- add_subdirectory(${json_SOURCE_DIR} ${json_BINARY_DIR} EXCLUDE_FROM_ALL)
-endif()
-
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-
-**Note**: The repository https://github.com/nlohmann/json download size is huge.
-It contains all the dataset used for the benchmarks. You might want to depend on
-a smaller repository. For instance, you might want to replace the URL above by
-https://github.com/ArthurSonzogni/nlohmann_json_cmake_fetchcontent
-
-#### Supporting Both
-
-To allow your project to support either an externally supplied or an embedded JSON library, you can use a pattern akin to the following:
-
-``` cmake
-# Top level CMakeLists.txt
-project(FOO)
-...
-option(FOO_USE_EXTERNAL_JSON "Use an external JSON library" OFF)
-...
-add_subdirectory(thirdparty)
-...
-add_library(foo ...)
-...
-# Note that the namespaced target will always be available regardless of the
-# import method
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-```cmake
-# thirdparty/CMakeLists.txt
-...
-if(FOO_USE_EXTERNAL_JSON)
- find_package(nlohmann_json 3.2.0 REQUIRED)
-else()
- set(JSON_BuildTests OFF CACHE INTERNAL "")
- add_subdirectory(nlohmann_json)
-endif()
-...
-```
-
-`thirdparty/nlohmann_json` is then a complete copy of this source tree.
-
-### Package Managers
-
-:beer: If you are using OS X and [Homebrew](https://brew.sh), just type `brew tap nlohmann/json` and `brew install nlohmann-json` and you're set. If you want the bleeding edge rather than the latest release, use `brew install nlohmann-json --HEAD`.

-### Pkg-config
-
-If you are using bare Makefiles, you can use `pkg-config` to generate the include flags that point to where the library is installed:
-
-```sh
-pkg-config nlohmann_json --cflags
-```
-
-Users of the Meson build system will also be able to use a system wide library, which will be found by `pkg-config`:
-
-```meson
-json = dependency('nlohmann_json', required: true)
-```
## Examples
-Beside the examples below, you may want to check the [documentation](https://nlohmann.github.io/json/) where each function contains a separate code example (e.g., check out [`emplace()`](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a5338e282d1d02bed389d852dd670d98d.html#a5338e282d1d02bed389d852dd670d98d)).

+
+## Integration
+
+[`json.hpp`](https://github.com/nlohmann/json/blob/develop/single_include/nlohmann/json.hpp) is the single required file in `single_include/nlohmann` or [released here](https://github.com/nlohmann/json/releases). You need to add
+
+```cpp
+#include <nlohmann/json.hpp>
+
+// for convenience
+using json = nlohmann::json;
+```
+
+to the files you want to process JSON and set the necessary switches to enable C++11 (e.g., `-std=c++11` for GCC and Clang).
+
+You can further use file [`include/nlohmann/json_fwd.hpp`](https://github.com/nlohmann/json/blob/develop/include/nlohmann/json_fwd.hpp) for forward-declarations. The installation of json_fwd.hpp (as part of cmake's install step), can be achieved by setting `-DJSON_MultipleHeaders=ON`.
+
+### CMake
+
+You can also use the `nlohmann_json::nlohmann_json` interface target in CMake. This target populates the appropriate usage requirements for `INTERFACE_INCLUDE_DIRECTORIES` to point to the appropriate include directories and `INTERFACE_COMPILE_FEATURES` for the necessary C++11 flags.
+
+#### External
+
+To use this library from a CMake project, you can locate it directly with `find_package()` and use the namespaced imported target from the generated package configuration:
+
+```cmake
+# CMakeLists.txt
+find_package(nlohmann_json 3.2.0 REQUIRED)
+...
+add_library(foo ...)
+...
+target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
+```
+
+The package configuration file, `nlohmann_jsonConfig.cmake`, can be used either from an install tree or directly out of the build tree.
+
+#### Embedded
+
+To embed the library directly into an existing CMake project, place the entire source tree in a subdirectory and call `add_subdirectory()` in your `CMakeLists.txt` file:
+
+```cmake
+# Typically you don't care so much for a third party library's tests to be
+# run from your own project's code.
+set(JSON_BuildTests OFF CACHE INTERNAL "")
+
+# If you only include this third party in PRIVATE source files, you do not
+# need to install it when your main project gets installed.
+# set(JSON_Install OFF CACHE INTERNAL "")
+
+# Don't use include(nlohmann_json/CMakeLists.txt) since that carries with it
+# unintended consequences that will break the build. It's generally
+# discouraged (although not necessarily well documented as such) to use
+# include(...) for pulling in other CMake projects anyways.
+add_subdirectory(nlohmann_json)
+...
+add_library(foo ...)
+...
+target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
+```
+
+##### Embedded (FetchContent)
+
+Since CMake v3.11,
+[FetchContent](https://cmake.org/cmake/help/v3.11/module/FetchContent.html) can
+be used to automatically download the repository as a dependency at configure time.
+
+Example:
+```cmake
+include(FetchContent)
+
+FetchContent_Declare(json
+ GIT_REPOSITORY https://github.com/nlohmann/json.git
+ GIT_TAG v3.7.3)
+
+FetchContent_GetProperties(json)
+if(NOT json_POPULATED)
+ FetchContent_Populate(json)
+ add_subdirectory(${json_SOURCE_DIR} ${json_BINARY_DIR} EXCLUDE_FROM_ALL)
+endif()
+
+target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
+```
+
+**Note**: The repository https://github.com/nlohmann/json download size is huge.
+It contains all the dataset used for the benchmarks. You might want to depend on
+a smaller repository. For instance, you might want to replace the URL above by
+https://github.com/ArthurSonzogni/nlohmann_json_cmake_fetchcontent
+
+#### Supporting Both
+
+To allow your project to support either an externally supplied or an embedded JSON library, you can use a pattern akin to the following:
+
+``` cmake
+# Top level CMakeLists.txt
+project(FOO)
+...
+option(FOO_USE_EXTERNAL_JSON "Use an external JSON library" OFF)
+...
+add_subdirectory(thirdparty)
+...
+add_library(foo ...)
+...
+# Note that the namespaced target will always be available regardless of the
+# import method
+target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
+```
+```cmake
+# thirdparty/CMakeLists.txt
+...
+if(FOO_USE_EXTERNAL_JSON)
+ find_package(nlohmann_json 3.2.0 REQUIRED)
+else()
+ set(JSON_BuildTests OFF CACHE INTERNAL "")
+ add_subdirectory(nlohmann_json)
+endif()
+...
+```
+
+`thirdparty/nlohmann_json` is then a complete copy of this source tree.
+
+### Package Managers
+
+:beer: If you are using OS X and [Homebrew](https://brew.sh), just type `brew tap nlohmann/json` and `brew install nlohmann-json` and you're set. If you want the bleeding edge rather than the latest release, use `brew install nlohmann-json --HEAD`.
+
+If you are using the [Meson Build System](https://mesonbuild.com), add this source tree as a [meson subproject](https://mesonbuild.com/Subprojects.html#using-a-subproject). You may also use the `include.zip` published in this project's [Releases](https://github.com/nlohmann/json/releases) to reduce the size of the vendored source tree. Alternatively, you can get a wrap file by downloading it from [Meson WrapDB](https://wrapdb.mesonbuild.com/nlohmann_json), or simply use `meson wrap install nlohmann_json`. Please see the meson project for any issues regarding the packaging.
+
+The provided meson.build can also be used as an alternative to cmake for installing `nlohmann_json` system-wide in which case a pkg-config file is installed. To use it, simply have your build system require the `nlohmann_json` pkg-config dependency. In Meson, it is preferred to use the [`dependency()`](https://mesonbuild.com/Reference-manual.html#dependency) object with a subproject fallback, rather than using the subproject directly.
+
+If you are using [Conan](https://www.conan.io/) to manage your dependencies, merely add [`nlohmann_json/x.y.z`](https://conan.io/center/nlohmann_json) to your `conanfile`'s requires, where `x.y.z` is the release version you want to use. Please file issues [here](https://github.com/conan-io/conan-center-index/issues) if you experience problems with the packages.
+
+If you are using [Spack](https://www.spack.io/) to manage your dependencies, you can use the [`nlohmann-json` package](https://spack.readthedocs.io/en/latest/package_list.html#nlohmann-json). Please see the [spack project](https://github.com/spack/spack) for any issues regarding the packaging.
+
+If you are using [hunter](https://github.com/cpp-pm/hunter) on your project for external dependencies, then you can use the [nlohmann_json package](https://hunter.readthedocs.io/en/latest/packages/pkg/nlohmann_json.html). Please see the hunter project for any issues regarding the packaging.
+
+If you are using [Buckaroo](https://buckaroo.pm), you can install this library's module with `buckaroo add github.com/buckaroo-pm/nlohmann-json`. Please file issues [here](https://github.com/buckaroo-pm/nlohmann-json). There is a demo repo [here](https://github.com/njlr/buckaroo-nholmann-json-example).
+
+If you are using [vcpkg](https://github.com/Microsoft/vcpkg/) on your project for external dependencies, then you can use the [nlohmann-json package](https://github.com/Microsoft/vcpkg/tree/master/ports/nlohmann-json). Please see the vcpkg project for any issues regarding the packaging.
+
+If you are using [cget](https://cget.readthedocs.io/en/latest/), you can install the latest development version with `cget install nlohmann/json`. A specific version can be installed with `cget install nlohmann/json@v3.1.0`. Also, the multiple header version can be installed by adding the `-DJSON_MultipleHeaders=ON` flag (i.e., `cget install nlohmann/json -DJSON_MultipleHeaders=ON`).
+
+If you are using [CocoaPods](https://cocoapods.org), you can use the library by adding pod `"nlohmann_json", '~>3.1.2'` to your podfile (see [an example](https://bitbucket.org/benman/nlohmann_json-cocoapod/src/master/)). Please file issues [here](https://bitbucket.org/benman/nlohmann_json-cocoapod/issues?status=new&status=open).
+
+If you are using [NuGet](https://www.nuget.org), you can use the package [nlohmann.json](https://www.nuget.org/packages/nlohmann.json/). Please check [this extensive description](https://github.com/nlohmann/json/issues/1132#issuecomment-452250255) on how to use the package. Please files issues [here](https://github.com/hnkb/nlohmann-json-nuget/issues).
+
+If you are using [conda](https://conda.io/), you can use the package [nlohmann_json](https://github.com/conda-forge/nlohmann_json-feedstock) from [conda-forge](https://conda-forge.org) executing `conda install -c conda-forge nlohmann_json`. Please file issues [here](https://github.com/conda-forge/nlohmann_json-feedstock/issues).
+
+If you are using [MSYS2](https://www.msys2.org/), your can use the [mingw-w64-nlohmann-json](https://packages.msys2.org/base/mingw-w64-nlohmann-json) package, just type `pacman -S mingw-w64-i686-nlohmann-json` or `pacman -S mingw-w64-x86_64-nlohmann-json` for installation. Please file issues [here](https://github.com/msys2/MINGW-packages/issues/new?title=%5Bnlohmann-json%5D) if you experience problems with the packages.
+
+If you are using [`build2`](https://build2.org), you can use the [`nlohmann-json`](https://cppget.org/nlohmann-json) package from the public repository https://cppget.org or directly from the [package's sources repository](https://github.com/build2-packaging/nlohmann-json). In your project's `manifest` file, just add `depends: nlohmann-json` (probably with some [version constraints](https://build2.org/build2-toolchain/doc/build2-toolchain-intro.xhtml#guide-add-remove-deps)). If you are not familiar with using dependencies in `build2`, [please read this introduction](https://build2.org/build2-toolchain/doc/build2-toolchain-intro.xhtml).
+Please file issues [here](https://github.com/build2-packaging/nlohmann-json) if you experience problems with the packages.
+
+If you are using [`wsjcpp`](https://wsjcpp.org), you can use the command `wsjcpp install "https://github.com/nlohmann/json:develop"` to get the latest version. Note you can change the branch ":develop" to an existing tag or another branch.
+
+If you are using [`CPM.cmake`](https://github.com/TheLartians/CPM.cmake), you can check this [`example`](https://github.com/TheLartians/CPM.cmake/tree/master/examples/json). After [adding CPM script](https://github.com/TheLartians/CPM.cmake#adding-cpm) to your project, implement the following snippet to your CMake:
+
+```cmake
+CPMAddPackage(
+ NAME nlohmann_json
+ GITHUB_REPOSITORY nlohmann/json
+ VERSION 3.9.1)
+```
+
+### Pkg-config
+
+If you are using bare Makefiles, you can use `pkg-config` to generate the include flags that point to where the library is installed:
+
+```sh
+pkg-config nlohmann_json --cflags
+```
+
+Users of the Meson build system will also be able to use a system wide library, which will be found by `pkg-config`:
+
+```meson
+json = dependency('nlohmann_json', required: true)
+```
+

## Contact
If you have questions regarding the library, I would like to invite you to [open an issue at GitHub](https://github.com/nlohmann/json/issues/new/choose). Please describe your request, problem, or question as detailed as possible, and also mention the version of the library you are using as well as the version of your compiler and operating system. Opening an issue at GitHub allows other users and contributors to this library to collaborate. For instance, I have little experience with MSVC, and most issues in this regard have been solved by a growing community. If you have a look at the [closed issues](https://github.com/nlohmann/json/issues?q=is%3Aissue+is%3Aclosed), you will see that we react quite timely in most cases.

In particular, note [`operator[]`](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a233b02b0839ef798942dd46157cc0fe6.html#a233b02b0839ef798942dd46157cc0fe6) implements **unchecked access** for const objects: If the given key is not present, the behavior is undefined (think of a dereferenced null pointer) and yields an [assertion failure](https://github.com/nlohmann/json/issues/289) if assertions are switched on.

- As the exact type of a number is not defined in the [JSON specification](https://tools.ietf.org/html/rfc8259.html), this library tries to choose the best fitting C++ number type automatically. As a result, the type `double` may be used to store numbers which may yield [**floating-point exceptions**](https://github.com/nlohmann/json/issues/181) in certain rare situations if floating-point exceptions have been unmasked in the calling code. These exceptions are not caused by the library and need to be fixed in the calling code, such as by re-masking the exceptions prior to calling library functions.
- The code can be compiled without C++ **runtime type identification** features; that is, you can use the `-fno-rtti` compiler flag.
-- **Exceptions** are used widely within the library. They can, however, be switched off with either using the compiler flag `-fno-exceptions` or by defining the symbol `JSON_NOEXCEPTION`. In this case, exceptions are replaced by `abort()` calls. You can further control this behavior by defining `JSON_THROW_USER´` (overriding `throw`), `JSON_TRY_USER` (overriding `try`), and `JSON_CATCH_USER` (overriding `catch`). Note that `JSON_THROW_USER` should leave the current scope (e.g., by throwing or aborting), as continuing after it may yield undefined behavior.

## Execute unit tests

Note that during the `ctest` stage, several JSON test files are downloaded from an [external repository](https://github.com/nlohmann/json_test_data). If policies forbid downloading artifacts during testing, you can download the files yourself and pass the directory with the test files via `-DJSON_TestDataDirectory=path` to CMake. Then, no Internet connectivity is required. See [issue #2189](https://github.com/nlohmann/json/issues/2189) for more information.
-In case you have downloaded the library rather than checked out the code via Git, test `cmake_fetch_content_configure`. Please execute `ctest -LE git_required` to skip these tests. See [issue #2189](https://github.com/nlohmann/json/issues/2189) for more information.

+Some tests change the installed files and hence make the whole process not reproducible. Please execute `ctest -LE not_reproducible` to skip these tests. See [issue #2324](https://github.com/nlohmann/json/issues/2324) for more information.

-# How to contribute #
-
-We'd love to accept your patches and contributions to this project. There are
-a just a few small guidelines you need to follow.
-
-
-## Contributor License Agreement ##
-
-Contributions to any Google project must be accompanied by a Contributor
-License Agreement. This is not a copyright **assignment**, it simply gives
-Google permission to use and redistribute your contributions as part of the
-project.
-
- * If you are an individual writing original source code and you're sure you
- own the intellectual property, then you'll need to sign an [individual
- CLA][].
-
- * If you work for a company that wants to allow you to contribute your work,
- then you'll need to sign a [corporate CLA][].
-
-You generally only need to submit a CLA once, so if you've already submitted
-one (even if it was for a different project), you probably don't need to do it
-again.
-
-[individual CLA]: https://developers.google.com/open-source/cla/individual
-[corporate CLA]: https://developers.google.com/open-source/cla/corporate
-
-Once your CLA is submitted (or if you already submitted one for
-another Google project), make a commit adding yourself to the
-[AUTHORS][] and [CONTRIBUTORS][] files. This commit can be part
-of your first [pull request][].
-
-[AUTHORS]: AUTHORS
-[CONTRIBUTORS]: CONTRIBUTORS
-
-
-## Submitting a patch ##
-
- 1. It's generally best to start by opening a new issue describing the bug or
- feature you're intending to fix. Even if you think it's relatively minor,
- it's helpful to know what people are working on. Mention in the initial
- issue that you are planning to work on that bug or feature so that it can
- be assigned to you.
-
- 1. Follow the normal process of [forking][] the project, and setup a new
- branch to work in. It's important that each group of changes be done in
- separate branches in order to ensure that a pull request only includes the
- commits related to that bug or feature.
-
- 1. Do your best to have [well-formed commit messages][] for each change.
- This provides consistency throughout the project, and ensures that commit
- messages are able to be formatted properly by various git tools.
-
- 1. Finally, push the commits to your fork and submit a [pull request][].

-[](https://coveralls.io/r/google/benchmark)
-[](https://slackin-iqtfqnpzxd.now.sh/)
-
-A library to support the benchmarking of functions, similar to unit-tests.
-
-Discussion group: https://groups.google.com/d/forum/benchmark-discuss
-
-IRC channel: https://freenode.net #googlebenchmark
-
-[Known issues and common problems](#known-issues)
-
-[Additional Tooling Documentation](docs/tools.md)
-
-[Assembly Testing Documentation](docs/AssemblyTests.md)
-
-
-## Building
-
-The basic steps for configuring and building the library look like this:
-
-```bash
-$ git clone https://github.com/google/benchmark.git
-# Benchmark requires Google Test as a dependency. Add the source tree as a subdirectory.
-$ git clone https://github.com/google/googletest.git benchmark/googletest
-$ mkdir build && cd build
-$ cmake -G <generator> [options] ../benchmark
-# Assuming a makefile generator was used
-$ make
-```
-
-Note that Google Benchmark requires Google Test to build and run the tests. This
-dependency can be provided two ways:
-
-* Checkout the Google Test sources into `benchmark/googletest` as above.
-* Otherwise, if `-DBENCHMARK_DOWNLOAD_DEPENDENCIES=ON` is specified during
- configuration, the library will automatically download and build any required
- dependencies.
-
-If you do not wish to build and run the tests, add `-DBENCHMARK_ENABLE_GTEST_TESTS=OFF`
-to `CMAKE_ARGS`.
-
-
-## Installation Guide
-
-For Ubuntu and Debian Based System
-
-First make sure you have git and cmake installed (If not please install it)
-
-```
-sudo apt-get install git
-sudo apt-get install cmake
-```
-
-Now, let's clone the repository and build it
-
-```
-git clone https://github.com/google/benchmark.git
-cd benchmark
-git clone https://github.com/google/googletest.git
-mkdir build
-cd build
-cmake .. -DCMAKE_BUILD_TYPE=RELEASE
-make
-```
-
-We need to install the library globally now
-
-```
-sudo make install
-```
-
-Now you have google/benchmark installed in your machine
-Note: Don't forget to link to pthread library while building
-
-## Stable and Experimental Library Versions
-
-The main branch contains the latest stable version of the benchmarking library;
-the API of which can be considered largely stable, with source breaking changes
-being made only upon the release of a new major version.
-
-Newer, experimental, features are implemented and tested on the
-[`v2` branch](https://github.com/google/benchmark/tree/v2). Users who wish
-to use, test, and provide feedback on the new features are encouraged to try
-this branch. However, this branch provides no stability guarantees and reserves
-the right to change and break the API at any time.
-
-##Prerequisite knowledge
-
-Before attempting to understand this framework one should ideally have some familiarity with the structure and format of the Google Test framework, upon which it is based. Documentation for Google Test, including a "Getting Started" (primer) guide, is available here:
-https://github.com/google/googletest/blob/master/googletest/docs/Documentation.md
-
-
-## Example usage
-### Basic usage
-Define a function that executes the code to be measured.
-
-```c++
-#include <benchmark/benchmark.h>
-
-static void BM_StringCreation(benchmark::State& state) {
- for (auto _ : state)
- std::string empty_string;
-}
-// Register the function as a benchmark
-BENCHMARK(BM_StringCreation);
-
-// Define another benchmark
-static void BM_StringCopy(benchmark::State& state) {
- std::string x = "hello";
- for (auto _ : state)
- std::string copy(x);
-}
-BENCHMARK(BM_StringCopy);
-
-BENCHMARK_MAIN();
-```
-
-Don't forget to inform your linker to add benchmark library e.g. through
-`-lbenchmark` compilation flag. Alternatively, you may leave out the
-`BENCHMARK_MAIN();` at the end of the source file and link against
-`-lbenchmark_main` to get the same default behavior.
-
-The benchmark library will reporting the timing for the code within the `for(...)` loop.
-
-### Passing arguments
-Sometimes a family of benchmarks can be implemented with just one routine that
-takes an extra argument to specify which one of the family of benchmarks to
-run. For example, the following code defines a family of benchmarks for
-measuring the speed of `memcpy()` calls of different lengths:
-
-```c++
-static void BM_memcpy(benchmark::State& state) {
- char* src = new char[state.range(0)];
- char* dst = new char[state.range(0)];
- memset(src, 'x', state.range(0));
- for (auto _ : state)
- memcpy(dst, src, state.range(0));
- state.SetBytesProcessed(int64_t(state.iterations()) *
- int64_t(state.range(0)));
- delete[] src;
- delete[] dst;
-}
-BENCHMARK(BM_memcpy)->Arg(8)->Arg(64)->Arg(512)->Arg(1<<10)->Arg(8<<10);
-```
-
-The preceding code is quite repetitive, and can be replaced with the following
-short-hand. The following invocation will pick a few appropriate arguments in
-the specified range and will generate a benchmark for each such argument.
-
-```c++
-BENCHMARK(BM_memcpy)->Range(8, 8<<10);
-```
-
-By default the arguments in the range are generated in multiples of eight and
-the command above selects [ 8, 64, 512, 4k, 8k ]. In the following code the
-range multiplier is changed to multiples of two.
-
-```c++
-BENCHMARK(BM_memcpy)->RangeMultiplier(2)->Range(8, 8<<10);
-```
-Now arguments generated are [ 8, 16, 32, 64, 128, 256, 512, 1024, 2k, 4k, 8k ].
-
-You might have a benchmark that depends on two or more inputs. For example, the
-following code defines a family of benchmarks for measuring the speed of set
-insertion.
-
-```c++
-static void BM_SetInsert(benchmark::State& state) {
- std::set<int> data;
- for (auto _ : state) {
- state.PauseTiming();
- data = ConstructRandomSet(state.range(0));
- state.ResumeTiming();
- for (int j = 0; j < state.range(1); ++j)
- data.insert(RandomNumber());
- }
-}
-BENCHMARK(BM_SetInsert)
- ->Args({1<<10, 128})
- ->Args({2<<10, 128})
- ->Args({4<<10, 128})
- ->Args({8<<10, 128})
- ->Args({1<<10, 512})
- ->Args({2<<10, 512})
- ->Args({4<<10, 512})
- ->Args({8<<10, 512});
-```
-
-The preceding code is quite repetitive, and can be replaced with the following
-short-hand. The following macro will pick a few appropriate arguments in the
-product of the two specified ranges and will generate a benchmark for each such
-pair.
-
-```c++
-BENCHMARK(BM_SetInsert)->Ranges({{1<<10, 8<<10}, {128, 512}});
-```
-
-For more complex patterns of inputs, passing a custom function to `Apply` allows
-programmatic specification of an arbitrary set of arguments on which to run the
-benchmark. The following example enumerates a dense range on one parameter,
-and a sparse range on the second.
-
-```c++
-static void CustomArguments(benchmark::internal::Benchmark* b) {
- for (int i = 0; i <= 10; ++i)
- for (int j = 32; j <= 1024*1024; j *= 8)
- b->Args({i, j});
-}
-BENCHMARK(BM_SetInsert)->Apply(CustomArguments);
-```
-
-### Calculate asymptotic complexity (Big O)
-Asymptotic complexity might be calculated for a family of benchmarks. The
-following code will calculate the coefficient for the high-order term in the
-running time and the normalized root-mean square error of string comparison.
-
-```c++
-static void BM_StringCompare(benchmark::State& state) {
- std::string s1(state.range(0), '-');
- std::string s2(state.range(0), '-');
- for (auto _ : state) {
- benchmark::DoNotOptimize(s1.compare(s2));
- }
- state.SetComplexityN(state.range(0));
-}
-BENCHMARK(BM_StringCompare)
- ->RangeMultiplier(2)->Range(1<<10, 1<<18)->Complexity(benchmark::oN);
-```
-
-As shown in the following invocation, asymptotic complexity might also be
-calculated automatically.
-
-```c++
-BENCHMARK(BM_StringCompare)
- ->RangeMultiplier(2)->Range(1<<10, 1<<18)->Complexity();
-```
-
-The following code will specify asymptotic complexity with a lambda function,
-that might be used to customize high-order term calculation.
-
-```c++
-BENCHMARK(BM_StringCompare)->RangeMultiplier(2)
- ->Range(1<<10, 1<<18)->Complexity([](int n)->double{return n; });
-```
-
-### Templated benchmarks
-Templated benchmarks work the same way: This example produces and consumes
-messages of size `sizeof(v)` `range_x` times. It also outputs throughput in the
-absence of multiprogramming.
-
-```c++
-template <class Q> int BM_Sequential(benchmark::State& state) {
- Q q;
- typename Q::value_type v;
- for (auto _ : state) {
- for (int i = state.range(0); i--; )
- q.push(v);
- for (int e = state.range(0); e--; )
- q.Wait(&v);
- }
- // actually messages, not bytes:
- state.SetBytesProcessed(
- static_cast<int64_t>(state.iterations())*state.range(0));
-}
-BENCHMARK_TEMPLATE(BM_Sequential, WaitQueue<int>)->Range(1<<0, 1<<10);
-```
-
-Three macros are provided for adding benchmark templates.
-
-```c++
-#ifdef BENCHMARK_HAS_CXX11
-#define BENCHMARK_TEMPLATE(func, ...) // Takes any number of parameters.
-#else // C++ < C++11
-#define BENCHMARK_TEMPLATE(func, arg1)
-#endif
-#define BENCHMARK_TEMPLATE1(func, arg1)
-#define BENCHMARK_TEMPLATE2(func, arg1, arg2)
-```
-
-### A Faster KeepRunning loop
-
-In C++11 mode, a ranged-based for loop should be used in preference to
-the `KeepRunning` loop for running the benchmarks. For example:
-
-```c++
-static void BM_Fast(benchmark::State &state) {
- for (auto _ : state) {
- FastOperation();
- }
-}
-BENCHMARK(BM_Fast);
-```
-
-The reason the ranged-for loop is faster than using `KeepRunning`, is
-because `KeepRunning` requires a memory load and store of the iteration count
-ever iteration, whereas the ranged-for variant is able to keep the iteration count
-in a register.
-
-For example, an empty inner loop of using the ranged-based for method looks like:
-
-```asm
-# Loop Init
- mov rbx, qword ptr [r14 + 104]
- call benchmark::State::StartKeepRunning()
- test rbx, rbx
- je .LoopEnd
-.LoopHeader: # =>This Inner Loop Header: Depth=1
- add rbx, -1
- jne .LoopHeader
-.LoopEnd:
-```
-
-Compared to an empty `KeepRunning` loop, which looks like:
-
-```asm
-.LoopHeader: # in Loop: Header=BB0_3 Depth=1
- cmp byte ptr [rbx], 1
- jne .LoopInit
-.LoopBody: # =>This Inner Loop Header: Depth=1
- mov rax, qword ptr [rbx + 8]
- lea rcx, [rax + 1]
- mov qword ptr [rbx + 8], rcx
- cmp rax, qword ptr [rbx + 104]
- jb .LoopHeader
- jmp .LoopEnd
-.LoopInit:
- mov rdi, rbx
- call benchmark::State::StartKeepRunning()
- jmp .LoopBody
-.LoopEnd:
-```
-
-Unless C++03 compatibility is required, the ranged-for variant of writing
-the benchmark loop should be preferred.
-
-## Passing arbitrary arguments to a benchmark
-In C++11 it is possible to define a benchmark that takes an arbitrary number
-of extra arguments. The `BENCHMARK_CAPTURE(func, test_case_name, ...args)`
-macro creates a benchmark that invokes `func` with the `benchmark::State` as
-the first argument followed by the specified `args...`.
-The `test_case_name` is appended to the name of the benchmark and
-should describe the values passed.
-
-```c++
-template <class ...ExtraArgs>
-void BM_takes_args(benchmark::State& state, ExtraArgs&&... extra_args) {
- [...]
-}
-// Registers a benchmark named "BM_takes_args/int_string_test" that passes
-// the specified values to `extra_args`.
-BENCHMARK_CAPTURE(BM_takes_args, int_string_test, 42, std::string("abc"));
-```
-Note that elements of `...args` may refer to global variables. Users should
-avoid modifying global state inside of a benchmark.
-
-## Using RegisterBenchmark(name, fn, args...)
-
-The `RegisterBenchmark(name, func, args...)` function provides an alternative
-way to create and register benchmarks.
-`RegisterBenchmark(name, func, args...)` creates, registers, and returns a
-pointer to a new benchmark with the specified `name` that invokes
-`func(st, args...)` where `st` is a `benchmark::State` object.
-
-Unlike the `BENCHMARK` registration macros, which can only be used at the global
-scope, the `RegisterBenchmark` can be called anywhere. This allows for
-benchmark tests to be registered programmatically.
-
-Additionally `RegisterBenchmark` allows any callable object to be registered
-as a benchmark. Including capturing lambdas and function objects.
-
-For Example:
-```c++
-auto BM_test = [](benchmark::State& st, auto Inputs) { /* ... */ };
-
-int main(int argc, char** argv) {
- for (auto& test_input : { /* ... */ })
- benchmark::RegisterBenchmark(test_input.name(), BM_test, test_input);
- benchmark::Initialize(&argc, argv);
- benchmark::RunSpecifiedBenchmarks();
-}
-```
-
-### Multithreaded benchmarks
-In a multithreaded test (benchmark invoked by multiple threads simultaneously),
-it is guaranteed that none of the threads will start until all have reached
-the start of the benchmark loop, and all will have finished before any thread
-exits the benchmark loop. (This behavior is also provided by the `KeepRunning()`
-API) As such, any global setup or teardown can be wrapped in a check against the thread
-index:
-
-```c++
-static void BM_MultiThreaded(benchmark::State& state) {
- if (state.thread_index == 0) {
- // Setup code here.
- }
- for (auto _ : state) {
- // Run the test as normal.
- }
- if (state.thread_index == 0) {
- // Teardown code here.
- }
-}
-BENCHMARK(BM_MultiThreaded)->Threads(2);
-```
-
-If the benchmarked code itself uses threads and you want to compare it to
-single-threaded code, you may want to use real-time ("wallclock") measurements
-for latency comparisons:
-
-```c++
-BENCHMARK(BM_test)->Range(8, 8<<10)->UseRealTime();
-```
-
-Without `UseRealTime`, CPU time is used by default.
-
-
-## Manual timing
-For benchmarking something for which neither CPU time nor real-time are
-correct or accurate enough, completely manual timing is supported using
-the `UseManualTime` function.
-
-When `UseManualTime` is used, the benchmarked code must call
-`SetIterationTime` once per iteration of the benchmark loop to
-report the manually measured time.
-
-An example use case for this is benchmarking GPU execution (e.g. OpenCL
-or CUDA kernels, OpenGL or Vulkan or Direct3D draw calls), which cannot
-be accurately measured using CPU time or real-time. Instead, they can be
-measured accurately using a dedicated API, and these measurement results
-can be reported back with `SetIterationTime`.
-
-```c++
-static void BM_ManualTiming(benchmark::State& state) {
- int microseconds = state.range(0);
- std::chrono::duration<double, std::micro> sleep_duration {
- static_cast<double>(microseconds)
- };
-
- for (auto _ : state) {
- auto start = std::chrono::high_resolution_clock::now();
- // Simulate some useful workload with a sleep
- std::this_thread::sleep_for(sleep_duration);
- auto end = std::chrono::high_resolution_clock::now();
-
- auto elapsed_seconds =
- std::chrono::duration_cast<std::chrono::duration<double>>(
- end - start);
-
- state.SetIterationTime(elapsed_seconds.count());
- }
-}
-BENCHMARK(BM_ManualTiming)->Range(1, 1<<17)->UseManualTime();
-```
-
-### Preventing optimisation
-To prevent a value or expression from being optimized away by the compiler
-the `benchmark::DoNotOptimize(...)` and `benchmark::ClobberMemory()`
-functions can be used.
-
-```c++
-static void BM_test(benchmark::State& state) {
- for (auto _ : state) {
- int x = 0;
- for (int i=0; i < 64; ++i) {
- benchmark::DoNotOptimize(x += i);
- }
- }
-}
-```
-
-`DoNotOptimize(<expr>)` forces the *result* of `<expr>` to be stored in either
-memory or a register. For GNU based compilers it acts as read/write barrier
-for global memory. More specifically it forces the compiler to flush pending
-writes to memory and reload any other values as necessary.
-
-Note that `DoNotOptimize(<expr>)` does not prevent optimizations on `<expr>`
-in any way. `<expr>` may even be removed entirely when the result is already
-known. For example:
-
-```c++
- /* Example 1: `<expr>` is removed entirely. */
- int foo(int x) { return x + 42; }
- while (...) DoNotOptimize(foo(0)); // Optimized to DoNotOptimize(42);
-
- /* Example 2: Result of '<expr>' is only reused */
- int bar(int) __attribute__((const));
- while (...) DoNotOptimize(bar(0)); // Optimized to:
- // int __result__ = bar(0);
- // while (...) DoNotOptimize(__result__);
-```
-
-The second tool for preventing optimizations is `ClobberMemory()`. In essence
-`ClobberMemory()` forces the compiler to perform all pending writes to global
-memory. Memory managed by block scope objects must be "escaped" using
-`DoNotOptimize(...)` before it can be clobbered. In the below example
-`ClobberMemory()` prevents the call to `v.push_back(42)` from being optimized
-away.
-
-```c++
-static void BM_vector_push_back(benchmark::State& state) {
- for (auto _ : state) {
- std::vector<int> v;
- v.reserve(1);
- benchmark::DoNotOptimize(v.data()); // Allow v.data() to be clobbered.
- v.push_back(42);
- benchmark::ClobberMemory(); // Force 42 to be written to memory.
- }
-}
-```
-
-Note that `ClobberMemory()` is only available for GNU or MSVC based compilers.
-
-### Set time unit manually
-If a benchmark runs a few milliseconds it may be hard to visually compare the
-measured times, since the output data is given in nanoseconds per default. In
-order to manually set the time unit, you can specify it manually:
-
-```c++
-BENCHMARK(BM_test)->Unit(benchmark::kMillisecond);
-```
-
-## Controlling number of iterations
-In all cases, the number of iterations for which the benchmark is run is
-governed by the amount of time the benchmark takes. Concretely, the number of
-iterations is at least one, not more than 1e9, until CPU time is greater than
-the minimum time, or the wallclock time is 5x minimum time. The minimum time is
-set as a flag `--benchmark_min_time` or per benchmark by calling `MinTime` on
-the registered benchmark object.
-
-## Reporting the mean, median and standard deviation by repeated benchmarks
-By default each benchmark is run once and that single result is reported.
-However benchmarks are often noisy and a single result may not be representative
-of the overall behavior. For this reason it's possible to repeatedly rerun the
-benchmark.
-
-The number of runs of each benchmark is specified globally by the
-`--benchmark_repetitions` flag or on a per benchmark basis by calling
-`Repetitions` on the registered benchmark object. When a benchmark is run more
-than once the mean, median and standard deviation of the runs will be reported.
-
-Additionally the `--benchmark_report_aggregates_only={true|false}` flag or
-`ReportAggregatesOnly(bool)` function can be used to change how repeated tests
-are reported. By default the result of each repeated run is reported. When this
-option is `true` only the mean, median and standard deviation of the runs is reported.
-Calling `ReportAggregatesOnly(bool)` on a registered benchmark object overrides
-the value of the flag for that benchmark.
-
-## User-defined statistics for repeated benchmarks
-While having mean, median and standard deviation is nice, this may not be
-enough for everyone. For example you may want to know what is the largest
-observation, e.g. because you have some real-time constraints. This is easy.
-The following code will specify a custom statistic to be calculated, defined
-by a lambda function.
-
-```c++
-void BM_spin_empty(benchmark::State& state) {
- for (auto _ : state) {
- for (int x = 0; x < state.range(0); ++x) {
- benchmark::DoNotOptimize(x);
- }
- }
-}
-
-BENCHMARK(BM_spin_empty)
- ->ComputeStatistics("max", [](const std::vector<double>& v) -> double {
- return *(std::max_element(std::begin(v), std::end(v)));
- })
- ->Arg(512);
-```
-
-## Fixtures
-Fixture tests are created by
-first defining a type that derives from `::benchmark::Fixture` and then
-creating/registering the tests using the following macros:
-
-* `BENCHMARK_F(ClassName, Method)`
-* `BENCHMARK_DEFINE_F(ClassName, Method)`
-* `BENCHMARK_REGISTER_F(ClassName, Method)`
-
-For Example:
-
-```c++
-class MyFixture : public benchmark::Fixture {};
-
-BENCHMARK_F(MyFixture, FooTest)(benchmark::State& st) {
- for (auto _ : st) {
- ...
- }
-}
-
-BENCHMARK_DEFINE_F(MyFixture, BarTest)(benchmark::State& st) {
- for (auto _ : st) {
- ...
- }
-}
-/* BarTest is NOT registered */
-BENCHMARK_REGISTER_F(MyFixture, BarTest)->Threads(2);
-/* BarTest is now registered */
-```
-
-### Templated fixtures
-Also you can create templated fixture by using the following macros:
-
-* `BENCHMARK_TEMPLATE_F(ClassName, Method, ...)`
-* `BENCHMARK_TEMPLATE_DEFINE_F(ClassName, Method, ...)`
-
-For example:
-```c++
-template<typename T>
-class MyFixture : public benchmark::Fixture {};
-
-BENCHMARK_TEMPLATE_F(MyFixture, IntTest, int)(benchmark::State& st) {
- for (auto _ : st) {
- ...
- }
-}
-
-BENCHMARK_TEMPLATE_DEFINE_F(MyFixture, DoubleTest, double)(benchmark::State& st) {
- for (auto _ : st) {
- ...
- }
-}
-
-BENCHMARK_REGISTER_F(MyFixture, DoubleTest)->Threads(2);
-```
-
-## User-defined counters
-
-You can add your own counters with user-defined names. The example below
-will add columns "Foo", "Bar" and "Baz" in its output:
-
-```c++
-static void UserCountersExample1(benchmark::State& state) {
- double numFoos = 0, numBars = 0, numBazs = 0;
- for (auto _ : state) {
- // ... count Foo,Bar,Baz events
- }
- state.counters["Foo"] = numFoos;
- state.counters["Bar"] = numBars;
- state.counters["Baz"] = numBazs;
-}
-```
-
-The `state.counters` object is a `std::map` with `std::string` keys
-and `Counter` values. The latter is a `double`-like class, via an implicit
-conversion to `double&`. Thus you can use all of the standard arithmetic
-assignment operators (`=,+=,-=,*=,/=`) to change the value of each counter.
-
-In multithreaded benchmarks, each counter is set on the calling thread only.
-When the benchmark finishes, the counters from each thread will be summed;
-the resulting sum is the value which will be shown for the benchmark.
-
-The `Counter` constructor accepts two parameters: the value as a `double`
-and a bit flag which allows you to show counters as rates and/or as
-per-thread averages:
-
-```c++
- // sets a simple counter
- state.counters["Foo"] = numFoos;
-
- // Set the counter as a rate. It will be presented divided
- // by the duration of the benchmark.
- state.counters["FooRate"] = Counter(numFoos, benchmark::Counter::kIsRate);
-
- // Set the counter as a thread-average quantity. It will
- // be presented divided by the number of threads.
- state.counters["FooAvg"] = Counter(numFoos, benchmark::Counter::kAvgThreads);
-
- // There's also a combined flag:
- state.counters["FooAvgRate"] = Counter(numFoos,benchmark::Counter::kAvgThreadsRate);
-```
-
-When you're compiling in C++11 mode or later you can use `insert()` with
-`std::initializer_list`:
-
-```c++
- // With C++11, this can be done:
- state.counters.insert({{"Foo", numFoos}, {"Bar", numBars}, {"Baz", numBazs}});
- // ... instead of:
- state.counters["Foo"] = numFoos;
- state.counters["Bar"] = numBars;
- state.counters["Baz"] = numBazs;
-```
-
-### Counter reporting
-
-When using the console reporter, by default, user counters are are printed at
-the end after the table, the same way as ``bytes_processed`` and
-``items_processed``. This is best for cases in which there are few counters,
-or where there are only a couple of lines per benchmark. Here's an example of
-the default output:
-
-```
-------------------------------------------------------------------------------
-Benchmark Time CPU Iterations UserCounters...
-------------------------------------------------------------------------------
-BM_UserCounter/threads:8 2248 ns 10277 ns 68808 Bar=16 Bat=40 Baz=24 Foo=8

-BM_CalculatePiRange/512 4900 ns 4901 ns 142696 3.14355
-```
-
-If this doesn't suit you, you can print each counter as a table column by
-passing the flag `--benchmark_counters_tabular=true` to the benchmark
-application. This is best for cases in which there are a lot of counters, or
-a lot of lines per individual benchmark. Note that this will trigger a
-reprinting of the table header any time the counter set changes between
-individual benchmarks. Here's an example of corresponding output when
-`--benchmark_counters_tabular=true` is passed:
-
-```

-```
-Note above the additional header printed when the benchmark changes from
-``BM_UserCounter`` to ``BM_Factorial``. This is because ``BM_Factorial`` does
-not have the same counter set as ``BM_UserCounter``.
-
-## Exiting Benchmarks in Error
-
-When errors caused by external influences, such as file I/O and network
-communication, occur within a benchmark the
-`State::SkipWithError(const char* msg)` function can be used to skip that run
-of benchmark and report the error. Note that only future iterations of the
-`KeepRunning()` are skipped. For the ranged-for version of the benchmark loop
-Users must explicitly exit the loop, otherwise all iterations will be performed.
-Users may explicitly return to exit the benchmark immediately.
-
-The `SkipWithError(...)` function may be used at any point within the benchmark,
-including before and after the benchmark loop.
-
-For example:
-
-```c++
-static void BM_test(benchmark::State& state) {
- auto resource = GetResource();
- if (!resource.good()) {
- state.SkipWithError("Resource is not good!");
- // KeepRunning() loop will not be entered.
- }
- for (state.KeepRunning()) {
- auto data = resource.read_data();
- if (!resource.good()) {
- state.SkipWithError("Failed to read data!");
- break; // Needed to skip the rest of the iteration.
- }
- do_stuff(data);
- }
-}
-
-static void BM_test_ranged_fo(benchmark::State & state) {
- state.SkipWithError("test will not be entered");
- for (auto _ : state) {
- state.SkipWithError("Failed!");
- break; // REQUIRED to prevent all further iterations.
- }
-}
-```
-
-## Running a subset of the benchmarks
-
-The `--benchmark_filter=<regex>` option can be used to only run the benchmarks
-which match the specified `<regex>`. For example:
-
-```bash
-$ ./run_benchmarks.x --benchmark_filter=BM_memcpy/32
-Run on (1 X 2300 MHz CPU )
-2016-06-25 19:34:24
-Benchmark Time CPU Iterations
-----------------------------------------------------
-BM_memcpy/32 11 ns 11 ns 79545455
-BM_memcpy/32k 2181 ns 2185 ns 324074
-BM_memcpy/32 12 ns 12 ns 54687500
-BM_memcpy/32k 1834 ns 1837 ns 357143
-```
-
-
-## Output Formats
-The library supports multiple output formats. Use the
-`--benchmark_format=<console|json|csv>` flag to set the format type. `console`
-is the default format.
-
-The Console format is intended to be a human readable format. By default
-the format generates color output. Context is output on stderr and the
-tabular data on stdout. Example tabular output looks like:
-```
-Benchmark Time(ns) CPU(ns) Iterations
-----------------------------------------------------------------------
-BM_SetInsert/1024/1 28928 29349 23853 133.097kB/s 33.2742k items/s
-BM_SetInsert/1024/8 32065 32913 21375 949.487kB/s 237.372k items/s
-BM_SetInsert/1024/10 33157 33648 21431 1.13369MB/s 290.225k items/s
-```
-
-The JSON format outputs human readable json split into two top level attributes.
-The `context` attribute contains information about the run in general, including
-information about the CPU and the date.
-The `benchmarks` attribute contains a list of every benchmark run. Example json
-output looks like:
-```json
-{
- "context": {
- "date": "2015/03/17-18:40:25",
- "num_cpus": 40,
- "mhz_per_cpu": 2801,
- "cpu_scaling_enabled": false,
- "build_type": "debug"
- },
- "benchmarks": [
- {
- "name": "BM_SetInsert/1024/1",
- "iterations": 94877,
- "real_time": 29275,
- "cpu_time": 29836,
- "bytes_per_second": 134066,
- "items_per_second": 33516
- },
- {
- "name": "BM_SetInsert/1024/8",
- "iterations": 21609,
- "real_time": 32317,
- "cpu_time": 32429,
- "bytes_per_second": 986770,
- "items_per_second": 246693
- },
- {
- "name": "BM_SetInsert/1024/10",
- "iterations": 21393,
- "real_time": 32724,
- "cpu_time": 33355,
- "bytes_per_second": 1199226,
- "items_per_second": 299807
- }
- ]
-}
-```
-
-The CSV format outputs comma-separated values. The `context` is output on stderr
-and the CSV itself on stdout. Example CSV output looks like:
-```
-name,iterations,real_time,cpu_time,bytes_per_second,items_per_second,label
-"BM_SetInsert/1024/1",65465,17890.7,8407.45,475768,118942,
-"BM_SetInsert/1024/8",116606,18810.1,9766.64,3.27646e+06,819115,
-"BM_SetInsert/1024/10",106365,17238.4,8421.53,4.74973e+06,1.18743e+06,
-```
-
-## Output Files
-The library supports writing the output of the benchmark to a file specified
-by `--benchmark_out=<filename>`. The format of the output can be specified
-using `--benchmark_out_format={json|console|csv}`. Specifying
-`--benchmark_out` does not suppress the console output.
-
-## Debug vs Release
-By default, benchmark builds as a debug library. You will see a warning in the output when this is the case. To build it as a release library instead, use:
-
-```
-cmake -DCMAKE_BUILD_TYPE=Release
-```
-
-To enable link-time optimisation, use
-
-```
-cmake -DCMAKE_BUILD_TYPE=Release -DBENCHMARK_ENABLE_LTO=true
-```
-
-If you are using gcc, you might need to set `GCC_AR` and `GCC_RANLIB` cmake cache variables, if autodetection fails.
-If you are using clang, you may need to set `LLVMAR_EXECUTABLE`, `LLVMNM_EXECUTABLE` and `LLVMRANLIB_EXECUTABLE` cmake cache variables.
-
-## Linking against the library
-
-When the library is built using GCC it is necessary to link with `-pthread`,
-due to how GCC implements `std::thread`.
-
-For GCC 4.x failing to link to pthreads will lead to runtime exceptions, not linker errors.
-See [issue #67](https://github.com/google/benchmark/issues/67) for more details.
-
-## Compiler Support
-
-Google Benchmark uses C++11 when building the library. As such we require
-a modern C++ toolchain, both compiler and standard library.
-
-The following minimum versions are strongly recommended build the library:
-
-* GCC 4.8
-* Clang 3.4
-* Visual Studio 2013
-* Intel 2015 Update 1
-
-Anything older *may* work.
-
-Note: Using the library and its headers in C++03 is supported. C++11 is only
-required to build the library.
-
-## Disable CPU frequency scaling
-If you see this error:
-```
-***WARNING*** CPU scaling is enabled, the benchmark real time measurements may be noisy and will incur extra overhead.
-```
-you might want to disable the CPU frequency scaling while running the benchmark:
-```bash
-sudo cpupower frequency-set --governor performance
-./mybench
-sudo cpupower frequency-set --governor powersave
-```
-
-# Known Issues
-
-### Windows with CMake
-
-* Users must manually link `shlwapi.lib`. Failure to do so may result
-in unresolved symbols.
-
-### Solaris
-
-* Users must explicitly link with kstat library (-lkstat compilation flag).

-# Assembly Tests
-
-The Benchmark library provides a number of functions whose primary
-purpose in to affect assembly generation, including `DoNotOptimize`
-and `ClobberMemory`. In addition there are other functions,
-such as `KeepRunning`, for which generating good assembly is paramount.
-
-For these functions it's important to have tests that verify the
-correctness and quality of the implementation. This requires testing
-the code generated by the compiler.
-
-This document describes how the Benchmark library tests compiler output,
-as well as how to properly write new tests.
-
-
-## Anatomy of a Test
-
-Writing a test has two steps:
-
-* Write the code you want to generate assembly for.
-* Add `// CHECK` lines to match against the verified assembly.
-
-Example:
-```c++
-
-// CHECK-LABEL: test_add:
-extern "C" int test_add() {
- extern int ExternInt;
- return ExternInt + 1;
-
- // CHECK: movl ExternInt(%rip), %eax
- // CHECK: addl %eax
- // CHECK: ret
-}
-
-```
-
-#### LLVM Filecheck
-
-[LLVM's Filecheck](https://llvm.org/docs/CommandGuide/FileCheck.html)
-is used to test the generated assembly against the `// CHECK` lines
-specified in the tests source file. Please see the documentation
-linked above for information on how to write `CHECK` directives.
-
-#### Tips and Tricks:
-
-* Tests should match the minimal amount of output required to establish
-correctness. `CHECK` directives don't have to match on the exact next line
-after the previous match, so tests should omit checks for unimportant
-bits of assembly. ([`CHECK-NEXT`](https://llvm.org/docs/CommandGuide/FileCheck.html#the-check-next-directive)
-can be used to ensure a match occurs exactly after the previous match).
-
-* The tests are compiled with `-O3 -g0`. So we're only testing the
-optimized output.
-
-* The assembly output is further cleaned up using `tools/strip_asm.py`.
-This removes comments, assembler directives, and unused labels before
-the test is run.
-
-* The generated and stripped assembly file for a test is output under
-`<build-directory>/test/<test-name>.s`
-
-* Filecheck supports using [`CHECK` prefixes](https://llvm.org/docs/CommandGuide/FileCheck.html#cmdoption-check-prefixes)
-to specify lines that should only match in certain situations.
-The Benchmark tests use `CHECK-CLANG` and `CHECK-GNU` for lines that
-are only expected to match Clang or GCC's output respectively. Normal
-`CHECK` lines match against all compilers. (Note: `CHECK-NOT` and
-`CHECK-LABEL` are NOT prefixes. They are versions of non-prefixed
-`CHECK` lines)
-
-* Use `extern "C"` to disable name mangling for specific functions. This
-makes them easier to name in the `CHECK` lines.
-
-
-## Problems Writing Portable Tests
-
-Writing tests which check the code generated by a compiler are
-inherently non-portable. Different compilers and even different compiler
-versions may generate entirely different code. The Benchmark tests
-must tolerate this.
-
-LLVM Filecheck provides a number of mechanisms to help write
-"more portable" tests; including [matching using regular expressions](https://llvm.org/docs/CommandGuide/FileCheck.html#filecheck-pattern-matching-syntax),
-allowing the creation of [named variables](https://llvm.org/docs/CommandGuide/FileCheck.html#filecheck-variables)
-for later matching, and [checking non-sequential matches](https://llvm.org/docs/CommandGuide/FileCheck.html#the-check-dag-directive).
-
-#### Capturing Variables
-
-For example, say GCC stores a variable in a register but Clang stores
-it in memory. To write a test that tolerates both cases we "capture"
-the destination of the store, and then use the captured expression
-to write the remainder of the test.
-
-```c++
-// CHECK-LABEL: test_div_no_op_into_shr:
-extern "C" void test_div_no_op_into_shr(int value) {
- int divisor = 2;
- benchmark::DoNotOptimize(divisor); // hide the value from the optimizer
- return value / divisor;
-
- // CHECK: movl $2, [[DEST:.*]]
- // CHECK: idivl [[DEST]]
- // CHECK: ret
-}
-```
-
-#### Using Regular Expressions to Match Differing Output
-
-Often tests require testing assembly lines which may subtly differ
-between compilers or compiler versions. A common example of this
-is matching stack frame addresses. In this case regular expressions
-can be used to match the differing bits of output. For example:
-
-```c++
-int ExternInt;
-struct Point { int x, y, z; };
-
-// CHECK-LABEL: test_store_point:
-extern "C" void test_store_point() {
- Point p{ExternInt, ExternInt, ExternInt};
- benchmark::DoNotOptimize(p);
-
- // CHECK: movl ExternInt(%rip), %eax
- // CHECK: movl %eax, -{{[0-9]+}}(%rsp)
- // CHECK: movl %eax, -{{[0-9]+}}(%rsp)
- // CHECK: movl %eax, -{{[0-9]+}}(%rsp)
- // CHECK: ret
-}
-```
-
-## Current Requirements and Limitations
-
-The tests require Filecheck to be installed along the `PATH` of the
-build machine. Otherwise the tests will be disabled.
-
-Additionally, as mentioned in the previous section, codegen tests are
-inherently non-portable. Currently the tests are limited to:
-
-* x86_64 targets.
-* Compiled with GCC or Clang
-
-Further work could be done, at least on a limited basis, to extend the
-tests to other architectures and compilers (using `CHECK` prefixes).
-
-Furthermore, the tests fail for builds which specify additional flags
-that modify code generation, including `--coverage` or `-fsanitize=`.

-# Benchmark Tools
-
-## compare_bench.py
-
-The `compare_bench.py` utility which can be used to compare the result of benchmarks.
-The program is invoked like:
-
-``` bash
-$ compare_bench.py <old-benchmark> <new-benchmark> [benchmark options]...
-```
-
-Where `<old-benchmark>` and `<new-benchmark>` either specify a benchmark executable file, or a JSON output file. The type of the input file is automatically detected. If a benchmark executable is specified then the benchmark is run to obtain the results. Otherwise the results are simply loaded from the output file.
-
-`[benchmark options]` will be passed to the benchmarks invocations. They can be anything that binary accepts, be it either normal `--benchmark_*` parameters, or some custom parameters your binary takes.
-
-The sample output using the JSON test files under `Inputs/` gives:
-
-``` bash
-$ ./compare_bench.py ./gbench/Inputs/test1_run1.json ./gbench/Inputs/test1_run2.json
-Comparing ./gbench/Inputs/test1_run1.json to ./gbench/Inputs/test1_run2.json

-
-As you can note, the values in `Time` and `CPU` columns are calculated as `(new - old) / |old|`.
-
-When a benchmark executable is run, the raw output from the benchmark is printed in real time to stdout. The sample output using `benchmark/basic_test` for both arguments looks like:
-
-```

-Obviously this example doesn't give any useful output, but it's intended to show the output format when 'compare_bench.py' needs to run benchmarks.
-
-## compare.py
-
-The `compare.py` can be used to compare the result of benchmarks.
-There are three modes of operation:
-
-1. Just compare two benchmarks, what `compare_bench.py` did.
-The program is invoked like:
-
-``` bash
-$ compare.py benchmarks <benchmark_baseline> <benchmark_contender> [benchmark options]...
-```
-Where `<benchmark_baseline>` and `<benchmark_contender>` either specify a benchmark executable file, or a JSON output file. The type of the input file is automatically detected.

-`[benchmark options]` will be passed to the benchmarks invocations. They can be anything that binary accepts, be it either normal `--benchmark_*` parameters, or some custom parameters your binary takes.

-
-What it does is for the every benchmark from the first run it looks for the benchmark with exactly the same name in the second run, and then compares the results. If the names differ, the benchmark is omitted from the diff.
-As you can note, the values in `Time` and `CPU` columns are calculated as `(new - old) / |old|`.
-
-2. Compare two different filters of one benchmark
-The program is invoked like:
-
-``` bash
-$ compare.py filters <benchmark> <filter_baseline> <filter_contender> [benchmark options]...
-```
-Where `<benchmark>` either specify a benchmark executable file, or a JSON output file. The type of the input file is automatically detected. If a benchmark executable is specified then the benchmark is run to obtain the results. Otherwise the results are simply loaded from the output file.
-
-Where `<filter_baseline>` and `<filter_contender>` are the same regex filters that you would pass to the `[--benchmark_filter=<regex>]` parameter of the benchmark binary.
-
-`[benchmark options]` will be passed to the benchmarks invocations. They can be anything that binary accepts, be it either normal `--benchmark_*` parameters, or some custom parameters your binary takes.
-

-```
-
-As you can see, it applies filter to the benchmarks, both when running the benchmark, and before doing the diff. And to make the diff work, the matches are replaced with some common string. Thus, you can compare two different benchmark families within one benchmark binary.
-As you can note, the values in `Time` and `CPU` columns are calculated as `(new - old) / |old|`.
-
-3. Compare filter one from benchmark one to filter two from benchmark two:

-```
-
-Where `<benchmark_baseline>` and `<benchmark_contender>` either specify a benchmark executable file, or a JSON output file. The type of the input file is automatically detected.

-# How to release
-
-* Make sure you're on master and synced to HEAD
-* Ensure the project builds and tests run (sanity check only, obviously)
- * `parallel -j0 exec ::: test/*_test` can help ensure everything at least
- passes
-* Prepare release notes
- * `git log $(git describe --abbrev=0 --tags)..HEAD` gives you the list of
- commits between the last annotated tag and HEAD
- * Pick the most interesting.
-* Create a release through github's interface
- * Note this will create a lightweight tag.
- * Update this to an annotated tag:
- * `git pull --tags`
- * `git tag -a -f <tag> <tag>`
- * `git push --force origin`

-// CycleClock
-// A CycleClock tells you the current time in Cycles. The "time"
-// is actually time since power-on. This is like time() but doesn't
-// involve a system call and is much more precise.
-//
-// NOTE: Not all cpu/platform/kernel combinations guarantee that this
-// clock increments at a constant rate or is synchronized across all logical
-// cpus in a system.
-//
-// If you need the above guarantees, please consider using a different
-// API. There are efforts to provide an interface which provides a millisecond
-// granularity and implemented as a memory read. A memory read is generally
-// cheaper than the CycleClock for many architectures.
-//
-// Also, in some out of order CPU implementations, the CycleClock is not
-// serializing. So if you're trying to count at cycles granularity, your
-// data might be inaccurate due to out of order instruction execution.

+
+// (2)
+template<typename IteratorType>
+static bool accept(IteratorType first, IteratorType last,
+ const bool ignore_comments = false);
+```
+
+Checks whether the input is valid JSON.
+
+1. Reads from a compatible input.
+2. Reads from a pair of character iterators
+
+ The value_type of the iterator must be a integral type with size of 1, 2 or 4 bytes, which will be interpreted
+ respectively as UTF-8, UTF-16 and UTF-32.
+
+Unlike the [`parse`](parse.md) function, this function neither throws an exception in case of invalid JSON input
+(i.e., a parse error) nor creates diagnostic information.
+
+## Template parameters
+
+`InputType`
+: A compatible input, for instance:
+
+ - an `std::istream` object
+ - a `FILE` pointer
+ - a C-style array of characters
+ - a pointer to a null-terminated string of single byte characters
+ - an object `obj` for which `begin(obj)` and `end(obj)` produces a valid pair of iterators.
+
+`IteratorType`
+: a compatible iterator type
+
+## Parameters
+
+`i` (in)
+: Input to parse from.
+
+`ignore_comments` (in)
+: whether comments should be ignored and treated like whitespace (`#!cpp true`) or yield a parse error
+ (`#!cpp false`); (optional, `#!cpp false` by default)
+
+`first` (in)
+: iterator to start of character range
+
+`last` (in)
+: iterator to end of character range
+
+## Return value
+
+Whether the input is valid JSON.
+
+## Exception safety
+
+Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
+
+## Complexity
+
+Linear in the length of the input. The parser is a predictive LL(1) parser.
+
+## Notes
+
+(1) A UTF-8 byte order mark is silently ignored.
+
+## Examples
+
+??? example
+
+ The example below demonstrates the `accept()` function reading from a string.
+
+ ```cpp
+ --8<-- "examples/accept__string.cpp"
+ ```
+
+ Output:
+
+ ```json
+ --8<-- "examples/accept__string.output"
+ ```
+
+## Version history
+
+- Added in version 3.0.0.
+- Ignoring comments via `ignore_comments` added in version 3.9.0.

+# basic_json::array
+
+```cpp
+static basic_json array(initializer_list_t init = {});
+```
+
+Creates a JSON array value from a given initializer list. That is, given a list of values `a, b, c`, creates the JSON
+value `#!json [a, b, c]`. If the initializer list is empty, the empty array `#!json []` is created.
+
+## Parameters
+
+`init` (in)
+: initializer list with JSON values to create an array from (optional)
+
+## Return value
+
+JSON array value
+
+## Exception safety
+
+Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
+
+## Complexity
+
+Linear in the size of `init`.
+
+## Notes
+
+This function is only needed to express two edge cases that cannot be realized with the initializer list constructor
+([`basic_json(initializer_list_t, bool, value_t)`](basic_json.md)). These cases are:
+
+1. creating an array whose elements are all pairs whose first element is a string -- in this case, the initializer list
+ constructor would create an object, taking the first elements as keys
+2. creating an empty array -- passing the empty initializer list to the initializer list constructor yields an empty
+ object
+
+## Examples
+
+??? example
+
+ The following code shows an example for the `array` function.
+
+ ```cpp
+ --8<-- "examples/array.cpp"
+ ```
+
+ Output:
+
+ ```json
+ --8<-- "examples/array.output"
+ ```
+
+## Version history
+
+- Added in version 1.0.0.

+# basic_json::array_t
+
+```cpp
+using array_t = ArrayType<basic_json, AllocatorType<basic_json>>;
+```
+
+The type used to store JSON arrays.
+
+[RFC 8259](https://tools.ietf.org/html/rfc8259) describes JSON arrays as follows:
+> An array is an ordered sequence of zero or more values.
+
+To store objects in C++, a type is defined by the template parameters explained below.
+
+## Template parameters
+
+`ArrayType`
+: container type to store arrays (e.g., `std::vector` or `std::list`)
+
+`AllocatorType`
+: the allocator to use for objects (e.g., `std::allocator`)
+
+## Notes
+
+#### Default type
+
+With the default values for `ArrayType` (`std::vector`) and `AllocatorType` (`std::allocator`), the default value for
+`array_t` is:
+
+```cpp
+std::vector<
+ basic_json, // value_type
+ std::allocator<basic_json> // allocator_type
+>
+```
+
+#### Limits
+
+[RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
+> An implementation may set limits on the maximum depth of nesting.
+
+In this class, the array's limit of nesting is not explicitly constrained. However, a maximum depth of nesting may be
+introduced by the compiler or runtime environment. A theoretical limit can be queried by calling the
+[`max_size`](max_size.md) function of a JSON array.
+
+#### Storage
+
+Arrays are stored as pointers in a `basic_json` type. That is, for any access to array values, a pointer of type
+`#!cpp array_t*` must be dereferenced.

+
+## Exceptions
+
+1. The function can throw the following exceptions:
+ - Throws [`type_error.304`](../../home/exceptions.md#jsonexceptiontype_error304) if the JSON value is not an array;
+ in this case, calling `at` with an index makes no sense. See example below.
+ - Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if the index `idx` is out of
+ range of the array; that is, `idx >= size()`. See example below.
+2. The function can throw the following exceptions:
+ - Throws [`type_error.304`](../../home/exceptions.md#jsonexceptiontype_error304) if the JSON value is not an object;
+ in this case, calling `at` with a key makes no sense. See example below.
+ - Throws [`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403) if the key `key` is is not
+ stored in the object; that is, `find(key) == end()`. See example below.
+3. The function can throw the following exceptions:
+ - Throws [`parse_error.106`](../../home/exceptions.md#jsonexceptionparse_error106) if an array index in the passed
+ JSON pointer `ptr` begins with '0'. See example below.
+ - Throws [`parse_error.109`](../../home/exceptions.md#jsonexceptionparse_error109) if an array index in the passed
+ JSON pointer `ptr` is not a number. See example below.
+ - Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if an array index in the passed
+ JSON pointer `ptr` is out of range. See example below.
+ - Throws [`out_of_range.402`](../../home/exceptions.md#jsonexceptionout_of_range402) if the array index '-' is used
+ in the passed JSON pointer `ptr`. As `at` provides checked access (and no elements are implicitly inserted), the
+ index '-' is always invalid. See example below.
+ - Throws [`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403) if the JSON pointer describes a
+ key of an object which cannot be found. See example below.
+ - Throws [`out_of_range.404`](../../home/exceptions.md#jsonexceptionout_of_range404) if the JSON pointer `ptr` can
+ not be resolved. See example below.

+
+1. Create an empty JSON value with a given type. The value will be default initialized with an empty value which depends
+ on the type:
+
+ Value type | initial value
+ ----------- | -------------
+ null | `#!json null`
+ boolean | `#!json false`
+ string | `#!json ""`
+ number | `#!json 0`
+ object | `#!json {}`
+ array | `#!json []`
+ binary | empty array
+
+2. Create a `#!json null` JSON value. It either takes a null pointer as parameter (explicitly creating `#!json null`)
+ or no parameter (implicitly creating `#!json null`). The passed null pointer itself is not read -- it is only used to
+ choose the right constructor.
+
+3. This is a "catch all" constructor for all compatible JSON types; that is, types for which a `to_json()` method
+ exists. The constructor forwards the parameter `val` to that method (to `json_serializer<U>::to_json` method with
+ `U = uncvref_t<CompatibleType>`, to be exact).
+
+ Template type `CompatibleType` includes, but is not limited to, the following types:
+
+ - **arrays**: [`array_t`](array_t.md) and all kinds of compatible containers such as `std::vector`, `std::deque`,
+ `std::list`, `std::forward_list`, `std::array`, `std::valarray`, `std::set`, `std::unordered_set`, `std::multiset`,
+ and `std::unordered_multiset` with a `value_type` from which a `basic_json` value can be constructed.
+ - **objects**: [`object_t`](object_t.md) and all kinds of compatible associative containers such as `std::map`,
+ `std::unordered_map`, `std::multimap`, and `std::unordered_multimap` with a `key_type` compatible to `string_t`
+ and a `value_type` from which a `basic_json` value can be constructed.
+ - **strings**: `string_t`, string literals, and all compatible string containers can be used.
+ - **numbers**: [`number_integer_t`](number_integer_t.md), [`number_unsigned_t`](number_unsigned_t.md),
+ [`number_float_t`](number_float_t.md), and all convertible number types such as `int`, `size_t`, `int64_t`, `float`
+ or `double` can be used.
+ - **boolean**: `boolean_t` / `bool` can be used.
+ - **binary**: `binary_t` / `std::vector<uint8_t>` may be used; unfortunately because string literals cannot be
+ distinguished from binary character arrays by the C++ type system, all types compatible with `const char*` will be
+ directed to the string constructor instead. This is both for backwards compatibility, and due to the fact that a
+ binary type is not a standard JSON type.
+
+ See the examples below.
+
+4. This is a constructor for existing `basic_json` types. It does not hijack copy/move constructors, since the parameter
+ has different template arguments than the current ones.
+
+ The constructor tries to convert the internal `m_value` of the parameter.
+
+5. Creates a JSON value of type array or object from the passed initializer list `init`. In case `type_deduction` is
+ `#!cpp true` (default), the type of the JSON value to be created is deducted from the initializer list `init`
+ according to the following rules:
+
+ 1. If the list is empty, an empty JSON object value `{}` is created.
+ 2. If the list consists of pairs whose first element is a string, a JSON object value is created where the first
+ elements of the pairs are treated as keys and the second elements are as values.
+ 3. In all other cases, an array is created.
+
+ The rules aim to create the best fit between a C++ initializer list and JSON values. The rationale is as follows:
+
+ 1. The empty initializer list is written as `#!cpp {}` which is exactly an empty JSON object.
+ 2. C++ has no way of describing mapped types other than to list a list of pairs. As JSON requires that keys must be
+ of type string, rule 2 is the weakest constraint one can pose on initializer lists to interpret them as an
+ object.
+ 3. In all other cases, the initializer list could not be interpreted as JSON object type, so interpreting it as JSON
+ array type is safe.
+
+ With the rules described above, the following JSON values cannot be expressed by an initializer list:
+
+ - the empty array (`#!json []`): use `array(initializer_list_t)` with an empty initializer list in this case
+ - arrays whose elements satisfy rule 2: use `array(initializer_list_t)` with the same initializer list in this case
+
+6. Constructs a JSON array value by creating `cnt` copies of a passed value. In case `cnt` is `0`, an empty array is
+ created.
+
+7. Constructs the JSON value with the contents of the range `[first, last)`. The semantics depends on the different
+ types a JSON value can have:
+
+ - In case of a `#!json null` type, [invalid_iterator.206](../../home/exceptions.md#jsonexceptioninvalid_iterator206)
+ is thrown.
+ - In case of other primitive types (number, boolean, or string), `first` must be `begin()` and `last` must be
+ `end()`. In this case, the value is copied. Otherwise,
+ [`invalid_iterator.204`](../../home/exceptions.md#jsonexceptioninvalid_iterator204) is thrown.
+ - In case of structured types (array, object), the constructor behaves as similar versions for `std::vector` or
+ `std::map`; that is, a JSON array or object is constructed from the values in the range.
+
+8. Creates a copy of a given JSON value.
+
+9. Move constructor. Constructs a JSON value with the contents of the given value `other` using move semantics. It
+ "steals" the resources from `other` and leaves it as JSON `#!json null` value.
+
+## Template parameters
+
+`CompatibleType`
+: a type such that:
+
+ - `CompatibleType` is not derived from `std::istream`,
+ - `CompatibleType` is not `basic_json` (to avoid hijacking copy/move constructors),
+ - `CompatibleType` is not a different `basic_json` type (i.e. with different template arguments)
+ - `CompatibleType` is not a `basic_json` nested type (e.g., `json_pointer`, `iterator`, etc.)
+ - `json_serializer<U>` (with `U = uncvref_t<CompatibleType>`) has a `to_json(basic_json_t&, CompatibleType&&)`
+ method
+
+`BasicJsonType`:
+: a type such that:
+
+ - `BasicJsonType` is a `basic_json` type.
+ - `BasicJsonType` has different template arguments than `basic_json_t`.
+
+## Parameters
+
+`v` (in)
+: the type of the value to create
+
+`val` (in)
+: the value to be forwarded to the respective constructor
+
+`init` (in)
+: initializer list with JSON values
+
+`type_deduction` (in)
+: internal parameter; when set to `#!cpp true`, the type of the JSON value is deducted from the initializer list
+ `init`; when set to `#!cpp false`, the type provided via `manual_type` is forced. This mode is used by the functions
+ `array(initializer_list_t)` and `object(initializer_list_t)`.
+
+`manual_type` (in)
+: internal parameter; when `type_deduction` is set to `#!cpp false`, the created JSON value will use the provided type
+ (only `value_t::array` and `value_t::object` are valid); when `type_deduction` is set to `#!cpp true`, this
+ parameter has no effect
+
+`cnt` (in)
+: the number of JSON copies of `val` to create
+
+`first` (in)
+: begin of the range to copy from (included)
+
+`last` (in)
+: end of the range to copy from (excluded)
+
+`other` (in)
+: the JSON value to copy/move

+7. The function can throw the following exceptions:
+ - Throws [`invalid_iterator.201`](../../home/exceptions.md#jsonexceptioninvalid_iterator201) if iterators `first`

+ `[first, last)` is undefined.
+ - Throws [`invalid_iterator.204`](../../home/exceptions.md#jsonexceptioninvalid_iterator204) if iterators `first`
+ and `last` belong to a primitive type (number, boolean, or string), but `first` does not point to the first
+ element any more. In this case, the range `[first, last)` is undefined. See example code below.
+ - Throws [`invalid_iterator.206`](../../home/exceptions.md#jsonexceptioninvalid_iterator206) if iterators `first`

+## Notes
+
+- Overload 5:
+
+ !!! note
+
+ When used without parentheses around an empty initializer list, `basic_json()` is called instead of this
+ function, yielding the JSON `#!json null` value.
+
+- Overload 7:
+
+ !!! info "Preconditions"
+
+ - Iterators `first` and `last` must be initialized. **This precondition is enforced with an assertion (see
+ warning).** If assertions are switched off, a violation of this precondition yields undefined behavior.
+ - Range `[first, last)` is valid. Usually, this precondition cannot be checked efficiently. Only certain edge
+ cases are detected; see the description of the exceptions above. A violation of this precondition yields
+ undefined behavior.
+
+ !!! warning
+
+ A precondition is enforced with a runtime assertion that will result in calling `std::abort` if this
+ precondition is not met. Assertions can be disabled by defining `NDEBUG` at compile time. See
+ <https://en.cppreference.com/w/cpp/error/assert> for more information.

+ !!! info "Postcondition"
+
+ `#!cpp *this == other`
+
+- Overload 9:
+
+ !!! info "Postconditions"

+## Notes
+
+Note, this function exists because of the difficulty in correctly specifying the correct template overload in the
+standard value ctor, as both JSON arrays and JSON binary arrays are backed with some form of a `std::vector`. Because
+JSON binary arrays are a non-standard extension it was decided that it would be best to prevent automatic initialization
+of a binary array type, for backwards compatibility and so it does not happen on accident.

+# basic_json::binary_t
+
+```cpp
+using binary_t = byte_container_with_subtype<BinaryType>;
+```
+
+This type is a type designed to carry binary data that appears in various serialized formats, such as CBOR's Major Type
+2, MessagePack's bin, and BSON's generic binary subtype. This type is NOT a part of standard JSON and exists solely for
+compatibility with these binary types. As such, it is simply defined as an ordered sequence of zero or more byte values.
+
+Additionally, as an implementation detail, the subtype of the binary data is carried around as a `std::uint8_t`, which
+is compatible with both of the binary data formats that use binary subtyping, (though the specific numbering is
+incompatible with each other, and it is up to the user to translate between them).
+
+[CBOR's RFC 7049](https://tools.ietf.org/html/rfc7049) describes this type as:
+> Major type 2: a byte string. The string's length in bytes is represented following the rules for positive integers
+> (major type 0).
+
+[MessagePack's documentation on the bin type
+family](https://github.com/msgpack/msgpack/blob/master/spec.md#bin-format-family) describes this type as:
+> Bin format family stores an byte array in 2, 3, or 5 bytes of extra bytes in addition to the size of the byte array.
+
+[BSON's specifications](http://bsonspec.org/spec.html) describe several binary types; however, this type is intended to
+represent the generic binary type which has the description:
+> Generic binary subtype - This is the most commonly used binary subtype and should be the 'default' for drivers and
+> tools.
+
+None of these impose any limitations on the internal representation other than the basic unit of storage be some type of
+array whose parts are decomposable into bytes.
+
+The default representation of this binary format is a `#!cpp std::vector<std::uint8_t>`, which is a very common way to
+represent a byte array in modern C++.
+
+## Template parameters
+
+`BinaryType`
+: container type to store arrays
+
+## Notes
+
+#### Default type
+
+The default values for `BinaryType` is `#!cpp std::vector<std::uint8_t>`.
+
+#### Storage
+
+Binary Arrays are stored as pointers in a `basic_json` type. That is, for any access to array values, a pointer of the
+type `#!cpp binary_t*` must be dereferenced.
+
+#### Notes on subtypes
+
+- CBOR
+ - Binary values are represented as byte strings. Subtypes are written as tags.
+
+- MessagePack
+ - If a subtype is given and the binary array contains exactly 1, 2, 4, 8, or 16 elements, the fixext family (fixext1,
+ fixext2, fixext4, fixext8) is used. For other sizes, the ext family (ext8, ext16, ext32) is used. The subtype is
+ then added as singed 8-bit integer.
+ - If no subtype is given, the bin family (bin8, bin16, bin32) is used.
+
+- BSON
+ - If a subtype is given, it is used and added as unsigned 8-bit integer.
+ - If no subtype is given, the generic binary subtype 0x00 is used.
+
+## Version history
+
+- Added in version 3.8.0. Changed type of subtype to `std::uint64_t` in version 3.10.0.

+
+The type used to store JSON booleans.
+
+[RFC 8259](https://tools.ietf.org/html/rfc8259) implicitly describes a boolean as a type which differentiates the two literals
+`#!json true` and `#!json false`.
+
+To store objects in C++, a type is defined by the template parameter `BooleanType` which chooses the type to use.
+
+## Notes
+
+#### Default type
+
+With the default values for `BooleanType` (`#!cpp bool`), the default value for `boolean_t` is `#!cpp bool`.
+
+#### Storage
+
+Boolean values are stored directly inside a `basic_json` type.

+[Container](https://en.cppreference.com/w/cpp/named_req/Container) concept; that is, their `empty()` functions have
+constant complexity.
+
+## Possible implementation
+
+```cpp
+bool empty() const noexcept
+{
+ return size() == 0;
+}
+```
+
+## Notes
+
+This function does not return whether a string stored as JSON value is empty -- it returns whether the JSON container
+itself is empty which is `#!cpp false` in the case of a string.
+
+## Example
+
+??? example
+
+ The following code uses `empty()` to check if a JSON object contains any elements.
+
+ ```cpp
+ --8<-- "examples/empty.cpp"
+ ```
+
+ Output:
+
+ ```json
+ --8<-- "examples/empty.output"
+ ```
+
+## Version history
+
+- Added in version 1.0.0.
+- Extended to return `#!cpp false` for binary types in version 3.8.0.

+# basic_json::erase
+
+```cpp
+// (1)
+iterator erase(iterator pos);
+const_iterator erase(const_iterator pos);
+
+// (2)
+iterator erase(iterator first, iterator last);
+const_iterator erase(const_iterator first, const_iterator last);
+
+// (3)
+size_type erase(const typename object_t::key_type& key);
+
+// (4)
+void erase(const size_type idx);
+```
+
+1. Removes an element from a JSON value specified by iterator `pos`. The iterator `pos` must be valid and
+ dereferenceable. Thus the `end()` iterator (which is valid, but is not dereferenceable) cannot be used as a value for
+ `pos`.
+
+ If called on a primitive type other than `#!json null`, the resulting JSON value will be `#!json null`.
+
+2. Remove an element range specified by `[first; last)` from a JSON value. The iterator `first` does not need to be
+ dereferenceable if `first == last`: erasing an empty range is a no-op.
+
+ If called on a primitive type other than `#!json null`, the resulting JSON value will be `#!json null`.
+
+3. Removes an element from a JSON object by key.
+
+4. Removes an element from a JSON array by index.
+
+## Parameters
+
+`pos` (in)
+: iterator to the element to remove
+
+`first` (in)
+: iterator to the beginning of the range to remove
+
+`last` (in)
+: iterator past the end of the range to remove
+
+`key` (in)
+: object key of the elements to remove
+
+`idx` (in)
+: array index of the element to remove
+
+## Return value
+
+1. Iterator following the last removed element. If the iterator `pos` refers to the last element, the `end()` iterator
+ is returned.
+2. Iterator following the last removed element. If the iterator `last` refers to the last element, the `end()` iterator
+ is returned.
+3. Number of elements removed. If `ObjectType` is the default `std::map` type, the return value will always be `0`
+ (`key` was not found) or `1` (`key` was found).
+4. /
+
+## Exceptions
+
+1. The function can throw the following exceptions:
+ - Throws [`type_error.307`](../../home/exceptions.md#jsonexceptiontype_error307) if called on a `null` value;
+ example: `"cannot use erase() with null"`
+ - Throws [`invalid_iterator.202`](../../home/exceptions.md#jsonexceptioninvalid_iterator202) if called on an
+ iterator which does not belong to the current JSON value; example: `"iterator does not fit current value"`
+ - Throws [`invalid_iterator.205`](../../home/exceptions.md#jsonexceptioninvalid_iterator205) if called on a
+ primitive type with invalid iterator (i.e., any iterator which is not `begin()`); example: `"iterator out of
+ range"`
+2. The function can throw thw following exceptions:
+ - Throws [`type_error.307`](../../home/exceptions.md#jsonexceptiontype_error307) if called on a `null` value;
+ example: `"cannot use erase() with null"`
+ - Throws [`invalid_iterator.203`](../../home/exceptions.md#jsonexceptioninvalid_iterator203) if called on iterators
+ which does not belong to the current JSON value; example: `"iterators do not fit current value"`
+ - Throws [`invalid_iterator.204`](../../home/exceptions.md#jsonexceptioninvalid_iterator204) if called on a
+ primitive type with invalid iterators (i.e., if `first != begin()` and `last != end()`); example: `"iterators out
+ of range"`
+3. The function can throw thw following exceptions:
+ - Throws [`type_error.307`](../../home/exceptions.md#jsonexceptiontype_error307) when called on a type other than
+ JSON object; example: `"cannot use erase() with null"`
+4. The function can throw thw following exceptions:
+ - Throws [`type_error.307`](../../home/exceptions.md#jsonexceptiontype_error307) when called on a type other than
+ JSON object; example: `"cannot use erase() with null"`
+ - Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) when `idx >= size()`; example:
+ `"array index 17 is out of range"`
+
+## Exception safety
+
+Strong exception safety: if an exception occurs, the original value stays intact.
+
+## Complexity
+
+1. The complexity depends on the type:
+ - objects: amortized constant
+ - arrays: linear in distance between `pos` and the end of the container
+ - strings and binary: linear in the length of the member
+ - other types: constant
+2. The complexity depends on the type:
+ - objects: `log(size()) + std::distance(first, last)`
+ - arrays: linear in the distance between `first` and `last`, plus linear
+ in the distance between `last` and end of the container
+ - strings and binary: linear in the length of the member
+ - other types: constant
+3. `log(size()) + count(key)`
+4. Linear in distance between `idx` and the end of the container.
+
+## Notes
+
+1. Invalidates iterators and references at or after the point of the
+ erase, including the `end()` iterator.
+2. /
+3. References and iterators to the erased elements are invalidated. Other references and iterators are not affected.
+4. /

+## Return value
+
+deserialized JSON value; in case of a parse error and `allow_exceptions` set to `#!cpp false`, the return value will be

+
+## Exception safety

+Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
+
+## Complexity
+
+Linear in the size of the input.
+
+## Example
+
+??? example
+
+ The example shows the deserialization of a byte vector in UBJSON format to a JSON value.

+# basic_json::front
+
+```cpp
+reference front();
+const_reference front() const;
+```
+
+Returns a reference to the first element in the container. For a JSON container `#!cpp c`, the expression
+`#!cpp c.front()` is equivalent to `#!cpp *c.begin()`.
+
+## Return value
+
+In case of a structured type (array or object), a reference to the first element is returned. In case of number, string,
+boolean, or binary values, a reference to the value is returned.
+
+## Exceptions
+
+If the JSON value is `#!json null`, exception
+[`invalid_iterator.214`](../../home/exceptions.md#jsonexceptioninvalid_iterator214) is thrown.
+
+## Exception safety
+
+Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
+
+## Complexity
+
+Constant.
+
+## Note
+
+!!! danger
+
+ Calling `front` on an empty array or object is undefined behavior and is **guarded by an assertion**!
+
+## Example
+
+??? example
+
+ The following code shows an example for `front()`.
+
+ ```cpp
+ --8<-- "examples/front.cpp"
+ ```
+
+ Output:

+1. Explicit type conversion between the JSON value and a compatible value which is
+ [CopyConstructible](https://en.cppreference.com/w/cpp/named_req/CopyConstructible) and
+ [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible). The value is converted by
+ calling the `json_serializer<ValueType>` `from_json()` method.
+
+ The function is equivalent to executing
+ ```cpp
+ ValueType ret;
+ JSONSerializer<ValueType>::from_json(*this, ret);
+ return ret;
+ ```
+
+ This overloads is chosen if:
+
+ - `ValueType` is not `basic_json`,
+ - `json_serializer<ValueType>` has a `from_json()` method of the form
+ `void from_json(const basic_json&, ValueType&)`, and

+ **not** [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible), the value is
+ converted by calling the `json_serializer<ValueType>` `from_json()` method.
+
+ The function is then equivalent to executing
+ ```cpp
+ return JSONSerializer<ValueTypeCV>::from_json(*this);
+ ```
+
+ This overloads is chosen if:
+
+ - `ValueType` is not `basic_json` and
+ - `json_serializer<ValueType>` has a `from_json()` method of the form
+ `ValueType from_json(const basic_json&)`
+
+ If `json_serializer<ValueType>` has both overloads of `from_json()`, the latter one is chosen.
+
+2. Overload for `basic_json` specializations. The function is equivalent to executing
+ ```cpp
+ return *this;
+ ```
+
+3. Explicit pointer access to the internally stored JSON value. No copies are made.
+
+## Template parameters
+
+`ValueType`
+: the value type to return
+
+`BasicJsonType`
+: a specialization of `basic_json`
+
+`PointerType`
+: pointer type; must be a pointer to [`array_t`](array_t.md), [`object_t`](object_t.md), [`string_t`](string_t.md),
+ [`boolean_t`](boolean_t.md), [`number_integer_t`](number_integer_t.md), or
+ [`number_unsigned_t`](number_unsigned_t.md), [`number_float_t`](number_float_t.md), or [`binary_t`](binary_t.md).
+ Other types will not compile.
+
+## Return value
+
+1. copy of the JSON value, converted to `ValueType`
+2. a copy of `#!cpp *this`, converted into `BasicJsonType`
+3. pointer to the internally stored JSON value if the requested pointer type fits to the JSON value; `#!cpp nullptr`
+ otherwise
+
+## Exceptions
+
+Depends on what `json_serializer<ValueType>` `from_json()` method throws
+
+## Notes
+
+!!! warning
+
+ Writing data to the pointee (overload 3) of the result yields an undefined state.
+
+## Example
+
+??? example
+
+ The example below shows several conversions from JSON values
+ to other types. There a few things to note: (1) Floating-point numbers can
+ be converted to integers, (2) A JSON array can be converted to a standard
+ `std::vector<short>`, (3) A JSON object can be converted to C++
+ associative containers such as `std::unordered_map<std::string, json>`.
+
+ ```cpp
+ --8<-- "examples/get__ValueType_const.cpp"
+ ```
+
+ Output:
+
+ ```json
+ --8<-- "examples/get__ValueType_const.output"
+ ```
+
+??? example
+
+ The example below shows how pointers to internal values of a JSON value can be requested. Note that no type
+ conversions are made and a `#cpp nullptr` is returned if the value and the requested pointer type does not match.
+
+ ```cpp
+ --8<-- "examples/get__PointerType.cpp"

+
+## Complexity
+
+1. Constant plus linear in the distance between `pos` and end of the container.
+2. Linear in `cnt` plus linear in the distance between `pos` and end of the container.
+3. Linear in `#!cpp std::distance(first, last)` plus linear in the distance between `pos` and end of the container.
+4. Linear in `ilist.size()` plus linear in the distance between `pos` and end of the container.
+5. Logarithmic: `O(N*log(size() + N))`, where `N` is the number of elements to insert.

+# basic_json::is_discarded
+
+```cpp
+constexpr bool is_discarded() const noexcept;
+```
+
+This function returns `#!cpp true` for a JSON value if either:
+
+- the value was discarded during parsing with a callback function (see [`parser_callback_t`](parser_callback_t.md)), or
+- the value is the result of parsing invalid JSON with parameter `allow_exceptions` set to `#!cpp false`; see
+ [`parse`](parse.md) for more information.
+
+## Return value
+
+`#!cpp true` if type is discarded, `#!cpp false` otherwise.
+
+## Exception safety
+
+No-throw guarantee: this member function never throws exceptions.
+
+## Complexity
+
+Constant.
+
+## Notes
+
+!!! note
+
+ Discarded values are never compared equal with [`operator==`](operator_eq.md). That is, checking whether a JSON
+ value `j` is discarded will only work via:
+
+ ```cpp
+ j.is_discarded()
+ ```
+
+ because
+
+ ```cpp
+ j == json::value_t::discarded
+ ```
+
+ will always be `#!cpp false`.
+
+!!! note
+
+ When a value is discarded by a callback function (see [`parser_callback_t`](parser_callback_t.md)) during parsing,
+ then it is removed when it is part of a structured value. For instance, if the second value of an array is discared,
+ instead of `#!json [null, discarded, false]`, the array `#!json [null, false]` is returned. Only if the top-level
+ value is discarded, the return value of the `parse` call is discarded.
+
+This function will always be `#!cpp false` for JSON values after parsing. That is, discarded values can only occur
+during parsing, but will be removed when inside a structured value or replaced by null in other cases.

+
+This function allows to access `iterator::key()` and `iterator::value()` during range-based for loops. In these loops, a
+reference to the JSON values is returned, so there is no access to the underlying iterator.
+
+For loop without `items()` function:
+
+```cpp
+for (auto it = j_object.begin(); it != j_object.end(); ++it)
+{
+ std::cout << "key: " << it.key() << ", value:" << it.value() << '\n';

+}
+```
+
+The `items()` function also allows to use

+
+## Notes
+
+When iterating over an array, `key()` will return the index of the element as string (see example). For primitive types
+(e.g., numbers), `key()` returns an empty string.
+
+!!! warning
+
+ Using `items()` on temporary objects is dangerous. Make sure the object's lifetime exeeds the iteration. See

+
+The merge patch format is primarily intended for use with the HTTP PATCH method as a means of describing a set of
+modifications to a target resource's content. This function applies a merge patch to the current JSON value.
+
+The function implements the following algorithm from Section 2 of
+[RFC 7396 (JSON Merge Patch)](https://tools.ietf.org/html/rfc7396):
+
+```python
+define MergePatch(Target, Patch):
+ if Patch is an Object:

+ Target = {} // Ignore the contents and set it to an empty Object
+ for each Name/Value pair in Patch:
+ if Value is null:

+ remove the Name/Value pair from Target
+ else:
+ Target[Name] = MergePatch(Target[Name], Value)
+ return Target
+ else:
+ return Patch
+```
+
+Thereby, `Target` is the current object; that is, the patch is applied to the current value.

+
+The type used to store JSON numbers (floating-point).
+
+[RFC 8259](https://tools.ietf.org/html/rfc8259) describes numbers as follows:
+> The representation of numbers is similar to that used in most programming languages. A number is represented in base
+> 10 using decimal digits. It contains an integer component that may be prefixed with an optional minus sign, which may
+> be followed by a fraction part and/or an exponent part. Leading zeros are not allowed. (...) Numeric values that
+> cannot be represented in the grammar below (such as Infinity and NaN) are not permitted.
+
+This description includes both integer and floating-point numbers. However, C++ allows more precise storage if it is
+known whether the number is a signed integer, an unsigned integer or a floating-point number. Therefore, three different
+types, [`number_integer_t`](number_integer_t.md), [`number_unsigned_t`](number_unsigned_t.md) and `number_float_t` are
+used.
+
+To store floating-point numbers in C++, a type is defined by the template parameter `NumberFloatType` which chooses the
+type to use.
+
+## Notes
+
+#### Default type
+
+With the default values for `NumberFloatType` (`double`), the default value for `number_float_t` is `#!cpp double`.
+
+#### Default behavior
+
+- The restrictions about leading zeros is not enforced in C++. Instead, leading zeros in floating-point literals will be
+ ignored. Internally, the value will be stored as decimal number. For instance, the C++ floating-point literal `01.2`
+ will be serialized to `1.2`. During deserialization, leading zeros yield an error.
+- Not-a-number (NaN) values will be serialized to `null`.
+
+#### Limits
+
+[RFC 8259](https://tools.ietf.org/html/rfc8259) states:
+> This specification allows implementations to set limits on the range and precision of numbers accepted. Since software
+> that implements IEEE 754-2008 binary64 (double precision) numbers is generally available and widely used, good
+> interoperability can be achieved by implementations that expect no more precision or range than these provide, in the
+> sense that implementations will approximate JSON numbers within the expected precision.
+
+This implementation does exactly follow this approach, as it uses double precision floating-point numbers. Note values
+smaller than `-1.79769313486232e+308` and values greater than `1.79769313486232e+308` will be stored as NaN internally
+and be serialized to `null`.
+
+#### Storage
+
+Floating-point number values are stored directly inside a `basic_json` type.

+
+With the default values for `NumberIntegerType` (`std::int64_t`), the default value for `number_integer_t` is
+`#!cpp std::int64_t`.
+
+#### Default behavior
+
+- The restrictions about leading zeros is not enforced in C++. Instead, leading zeros in integer literals lead to an
+ interpretation as octal number. Internally, the value will be stored as decimal number. For instance, the C++ integer
+ literal `010` will be serialized to `8`. During deserialization, leading zeros yield an error.
+- Not-a-number (NaN) values will be serialized to `null`.
+
+#### Limits
+
+[RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
+> An implementation may set limits on the range and precision of numbers.
+
+When the default type is used, the maximal integer number that can be stored is `9223372036854775807` (INT64_MAX) and
+the minimal integer number that can be stored is `-9223372036854775808` (INT64_MIN). Integer numbers that are out of
+range will yield over/underflow when used in a constructor. During deserialization, too large or small integer numbers
+will be automatically be stored as [`number_unsigned_t`](number_unsigned_t.md) or [`number_float_t`](number_float_t.md).
+
+[RFC 8259](https://tools.ietf.org/html/rfc8259) further states:
+> Note that when such software is used, numbers that are integers and are in the range \f$[-2^{53}+1, 2^{53}-1]\f$ are
+> interoperable in the sense that implementations will agree exactly on their numeric values.
+
+As this range is a subrange of the exactly supported range [INT64_MIN, INT64_MAX], this class's integer type is
+interoperable.
+
+#### Storage
+
+Integer number values are stored directly inside a `basic_json` type.

+> 10 using decimal digits. It contains an integer component that may be prefixed with an optional minus sign, which may
+> be followed by a fraction part and/or an exponent part. Leading zeros are not allowed. (...) Numeric values that
+> cannot be represented in the grammar below (such as Infinity and NaN) are not permitted.
+
+This description includes both integer and floating-point numbers. However, C++ allows more precise storage if it is
+known whether the number is a signed integer, an unsigned integer or a floating-point number. Therefore, three different
+types, [`number_integer_t`](number_integer_t.md), `number_unsigned_t` and [`number_float_t`](number_float_t.md) are
+used.
+
+To store unsigned integer numbers in C++, a type is defined by the template parameter `NumberUnsignedType` which chooses
+the type to use.
+
+## Notes
+
+#### Default type
+
+With the default values for `NumberUnsignedType` (`std::uint64_t`), the default value for `number_unsigned_t` is
+`#!cpp std::uint64_t`.
+
+#### Default behavior
+
+- The restrictions about leading zeros is not enforced in C++. Instead, leading zeros in integer literals lead to an
+ interpretation as octal number. Internally, the value will be stored as decimal number. For instance, the C++ integer
+ literal `010` will be serialized to `8`. During deserialization, leading zeros yield an error.
+- Not-a-number (NaN) values will be serialized to `null`.
+
+#### Limits
+
+[RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
+> An implementation may set limits on the range and precision of numbers.
+
+When the default type is used, the maximal integer number that can be stored is `18446744073709551615` (UINT64_MAX) and
+the minimal integer number that can be stored is `0`. Integer numbers that are out of range will yield over/underflow
+when used in a constructor. During deserialization, too large or small integer numbers will be automatically be stored
+as [`number_integer_t`](number_integer_t.md) or [`number_float_t`](number_float_t.md).
+
+[RFC 8259](https://tools.ietf.org/html/rfc8259) further states:
+> Note that when such software is used, numbers that are integers and are in the range \f$[-2^{53}+1, 2^{53}-1]\f$ are
+> interoperable in the sense that implementations will agree exactly on their numeric values.
+
+As this range is a subrange (when considered in conjunction with the `number_integer_t` type) of the exactly supported
+range [0, UINT64_MAX], this class's integer type is interoperable.
+
+#### Storage
+
+Integer number values are stored directly inside a `basic_json` type.

+# basic_json::object
+
+```cpp
+static basic_json object(initializer_list_t init = {});
+```
+
+Creates a JSON object value from a given initializer list. The initializer lists elements must be pairs, and their first
+elements must be strings. If the initializer list is empty, the empty object `#!json {}` is created.
+
+## Parameters
+
+`init` (in)
+: initializer list with JSON values to create an object from (optional)
+
+## Return value
+
+JSON object value
+
+## Exceptions
+
+Throws [`type_error.301`](../../home/exceptions.md#jsonexceptiontype_error301) if `init` is not a list of pairs whose
+first elements are strings. In this case, no object can be created. When such a value is passed to
+`basic_json(initializer_list_t, bool, value_t)`, an array would have been created from the passed initializer list
+`init`. See example below.
+
+## Exception safety
+
+Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
+
+## Complexity
+
+Linear in the size of `init`.
+
+## Notes
+
+This function is only added for symmetry reasons. In contrast to the related function `array(initializer_list_t)`, there
+are no cases which can only be expressed by this function. That is, any initializer list `init` can also be passed to
+the initializer list constructor `basic_json(initializer_list_t, bool, value_t)`.
+
+## Examples
+
+??? example
+
+ The following code shows an example for the `object` function.
+
+ ```cpp
+ --8<-- "examples/object.cpp"
+ ```
+
+ Output:
+
+ ```json
+ --8<-- "examples/object.output"

+
+```cpp
+using object_t = ObjectType<StringType,
+ basic_json,
+ object_comparator_t,
+ AllocatorType<std::pair<const StringType, basic_json>>>;
+```
+
+The type used to store JSON objects.
+
+[RFC 8259](https://tools.ietf.org/html/rfc8259) describes JSON objects as follows:
+> An object is an unordered collection of zero or more name/value pairs, where a name is a string and a value is a
+> string, number, boolean, null, object, or array.
+
+To store objects in C++, a type is defined by the template parameters described below.
+
+## Template parameters
+
+`ObjectType`
+: the container to store objects (e.g., `std::map` or `std::unordered_map`)
+
+`StringType`
+: the type of the keys or names (e.g., `std::string`). The comparison function `std::less<StringType>` is used to
+ order elements inside the container.
+
+`AllocatorType`
+: the allocator to use for objects (e.g., `std::allocator`)
+
+## Notes
+
+#### Default type
+
+With the default values for `ObjectType` (`std::map`), `StringType` (`std::string`), and `AllocatorType`
+(`std::allocator`), the default value for `object_t` is:
+
+```cpp
+// until C++14
+std::map<
+ std::string, // key_type
+ basic_json, // value_type
+ std::less<std::string>, // key_compare
+ std::allocator<std::pair<const std::string, basic_json>> // allocator_type
+>
+
+// since C++14
+std::map<
+ std::string, // key_type
+ basic_json, // value_type
+ std::less<>, // key_compare
+ std::allocator<std::pair<const std::string, basic_json>> // allocator_type
+>
+```
+
+See [`object_comparator_t`](object_comparator_t.md) for more information.
+
+#### Behavior
+
+The choice of `object_t` influences the behavior of the JSON class. With the default type, objects have the following
+behavior:
+
+- When all names are unique, objects will be interoperable in the sense that all software implementations receiving that
+ object will agree on the name-value mappings.
+- When the names within an object are not unique, it is unspecified which one of the values for a given key will be
+ chosen. For instance, `#!json {"key": 2, "key": 1}` could be equal to either `#!json {"key": 1}` or
+ `#!json {"key": 2}`.
+- Internally, name/value pairs are stored in lexicographical order of the names. Objects will also be serialized (see
+ [`dump`](dump.md)) in this order. For instance, `#!json {"b": 1, "a": 2}` and `#!json {"a": 2, "b": 1}` will be stored
+ and serialized as `#!json {"a": 2, "b": 1}`.
+- When comparing objects, the order of the name/value pairs is irrelevant. This makes objects interoperable in the sense
+ that they will not be affected by these differences. For instance, `#!json {"b": 1, "a": 2}` and
+ `#!json {"a": 2, "b": 1}` will be treated as equal.
+
+#### Limits
+
+[RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
+> An implementation may set limits on the maximum depth of nesting.
+
+In this class, the object's limit of nesting is not explicitly constrained. However, a maximum depth of nesting may be
+introduced by the compiler or runtime environment. A theoretical limit can be queried by calling the
+[`max_size`](max_size.md) function of a JSON object.
+
+#### Storage
+
+Objects are stored as pointers in a `basic_json` type. That is, for any access to object values, a pointer of type
+`object_t*` must be dereferenced.
+
+#### Object key order
+
+The order name/value pairs are added to the object is *not* preserved by the library. Therefore, iterating an object may
+return name/value pairs in a different order than they were originally stored. In fact, keys will be traversed in
+alphabetical order as `std::map` with `std::less` is used by default. Please note this behavior conforms to
+[RFC 8259](https://tools.ietf.org/html/rfc8259), because any order implements the specified "unordered" nature of JSON objects.

+
+## Notes
+
+!!! danger
+
+ 1. If the element with key `idx` does not exist, the behavior is undefined.
+ 2. If the element with key `key` does not exist, the behavior is undefined and is **guarded by an assertion**!
+
+1. The non-const version may add values: If `idx` is beyond the range of the array (i.e., `idx >= size()`), then the
+ array is silently filled up with `#!json null` values to make `idx` a valid reference to the last stored element. In
+ case the value was `#!json null` before, it is converted to an array.
+
+2. If `key` is not found in the object, then it is silently added to the object and filled with a `#!json null` value to
+ make `key` a valid reference. In case the value was `#!json null` before, it is converted to an object.
+
+3. `null` values are created in arrays and objects if necessary.
+
+ In particular:
+
+ - If the JSON pointer points to an object key that does not exist, it is created an filled with a `#!json null`
+ value before a reference to it is returned.
+ - If the JSON pointer points to an array index that does not exist, it is created an filled with a `#!json null`
+ value before a reference to it is returned. All indices between the current maximum and the given index are also
+ filled with `#!json null`.
+ - The special value `-` is treated as a synonym for the index past the end.
+
+## Exception safety
+
+Strong exception safety: if an exception occurs, the original value stays intact.
+
+## Complexity
+
+1. Constant if `idx` is in the range of the array. Otherwise linear in `idx - size()`.
+2. Logarithmic in the size of the container.
+3. Constant

+
+`rhs` (in)
+: second value to consider
+
+## Return value

+
+## Notes
+
+!!! note
+
+ - NaN values never compare equal to themselves or to other NaN values.
+ - JSON `#!cpp null` values are all equal.
+ - Discarded values never compare equal to themselves.
+
+!!! note
+
+ Floating-point numbers inside JSON values numbers are compared with `json::number_float_t::operator==` which is
+ `double::operator==` by default. To compare floating-point while respecting an epsilon, an alternative
+ [comparison function](https://github.com/mariokonrad/marnav/blob/master/include/marnav/math/floatingpoint.hpp#L34-#L39)
+ could be used, for instance
+
+ ```cpp
+ template<typename T, typename = typename std::enable_if<std::is_floating_point<T>::value, T>::type>
+ inline bool is_same(T a, T b, T epsilon = std::numeric_limits<T>::epsilon()) noexcept
+ {
+ return std::abs(a - b) <= epsilon;
+ }
+ ```
+
+ Or you can self-defined operator equal function like this:
+
+ ```cpp
+ bool my_equal(const_reference lhs, const_reference rhs)
+ {
+ const auto lhs_type lhs.type();
+ const auto rhs_type rhs.type();
+ if (lhs_type == rhs_type)
+ {
+ switch(lhs_type)
+ // self_defined case
+ case value_t::number_float:
+ return std::abs(lhs - rhs) <= std::numeric_limits<float>::epsilon();
+ // other cases remain the same with the original
+ ...
+ }
+ ...
+ }
+ ```

+
+```cpp
+template<typename BasicJsonType>
+using parser_callback_t =
+ std::function<bool(int depth, parse_event_t event, BasicJsonType& parsed)>;
+```
+
+With a parser callback function, the result of parsing a JSON text can be influenced. When passed to
+[`parse`](parse.md), it is called on certain events (passed as [`parse_event_t`](parse_event_t.md) via parameter
+`event`) with a set recursion depth `depth` and context JSON value `parsed`. The return value of the callback function
+is a boolean indicating whether the element that emitted the callback shall be kept or not.
+
+We distinguish six scenarios (determined by the event type) in which the callback function can be called. The following
+table describes the values of the parameters `depth`, `event`, and `parsed`.
+
+parameter `event` | description | parameter `depth` | parameter `parsed`
+------------------ | ----------- | ------------------ | -------------------
+`parse_event_t::object_start` | the parser read `{` and started to process a JSON object | depth of the parent of the JSON object | a JSON value with type discarded
+`parse_event_t::key` | the parser read a key of a value in an object | depth of the currently parsed JSON object | a JSON string containing the key
+`parse_event_t::object_end` | the parser read `}` and finished processing a JSON object | depth of the parent of the JSON object | the parsed JSON object
+`parse_event_t::array_start` | the parser read `[` and started to process a JSON array | depth of the parent of the JSON array | a JSON value with type discarded
+`parse_event_t::array_end` | the parser read `]` and finished processing a JSON array | depth of the parent of the JSON array | the parsed JSON array
+`parse_event_t::value` | the parser finished reading a JSON value | depth of the value | the parsed JSON value
+
+
+
+Discarding a value (i.e., returning `#!cpp false`) has different effects depending on the context in which function was
+called:
+
+- Discarded values in structured types are skipped. That is, the parser will behave as if the discarded value was never
+ read.
+- In case a value outside a structured type is skipped, it is replaced with `null`. This case happens if the top-level
+ element is skipped.
+
+## Parameters
+
+`depth` (in)
+: the depth of the recursion during parsing
+
+`event` (in)
+: an event of type [`parse_event_t`](parse_event_t.md) indicating the context in
+ the callback function has been called
+
+`parsed` (in, out)
+: the current intermediate parse result; note that
+ writing to this value has no effect for `parse_event_t::key` events
+
+## Return value
+
+Whether the JSON value which called the function during parsing should be kept (`#!cpp true`) or not (`#!cpp false`). In
+the latter case, it is either skipped completely or replaced by an empty discarded object.
+
+# Example

+# basic_json::patch
+
+```cpp
+basic_json patch(const basic_json& json_patch) const;
+```
+
+[JSON Patch](http://jsonpatch.com) defines a JSON document structure for expressing a sequence of operations to apply to
+a JSON) document. With this function, a JSON Patch is applied to the current JSON value by executing all operations from
+the patch.
+
+## Parameters
+
+`json_patch` (in)
+: JSON patch document
+
+## Return value
+
+patched document
+
+## Exceptions
+
+- Throws [`parse_error.104`](../../home/exceptions.md#jsonexceptionparse_error104) if the JSON patch does not consist of
+ an array of objects.
+- Throws [`parse_error.105`](../../home/exceptions.md#jsonexceptionparse_error105) if the JSON patch is malformed (e.g.,
+ mandatory attributes are missing); example: `"operation add must have member path"`.
+- Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if an array index is out of range.
+- Throws [`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403) if a JSON pointer inside the patch
+ could not be resolved successfully in the current JSON value; example: `"key baz not found"`.
+- Throws [`out_of_range.405`](../../home/exceptions.md#jsonexceptionout_of_range405) if JSON pointer has no parent
+ ("add", "remove", "move")
+- Throws [`out_of_range.501`](../../home/exceptions.md#jsonexceptionother_error501) if "test" operation was
+ unsuccessful.
+
+## Exception safety
+
+Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
+
+## Complexity
+
+Linear in the size of the JSON value and the length of the JSON patch. As usually only a fraction of the JSON value is
+affected by the patch, the complexity can usually be neglected.
+
+## Note
+
+The application of a patch is atomic: Either all operations succeed and the patched document is returned or an exception
+is thrown. In any case, the original value is not changed: the patch is applied to a copy of the value.
+
+## Example
+
+??? example
+
+ The following code shows how a JSON patch is applied to a value.
+
+ ```cpp
+ --8<-- "examples/patch.cpp"

+```
+
+1. Appends the given element `val` to the end of the JSON array. If the function is called on a JSON null value, an

+
+2. Inserts the given element `val` to the JSON object. If the function is called on a JSON null value, an empty object
+ is created before inserting `val`.
+
+3. This function allows to use `push_back` with an initializer list. In case
+
+ 1. the current value is an object,
+ 2. the initializer list `init` contains only two elements, and
+ 3. the first element of `init` is a string,

+ `init` is converted into an object element and added using `push_back(const typename object_t::value_type&)`.
+ Otherwise, `init` is converted to a JSON value and added using `push_back(basic_json&&)`.

+## Complexity
+
+1. Amortized constant.
+2. Logarithmic in the size of the container, O(log(`size()`)).
+3. Linear in the size of the initializer list `init`.
+
+## Notes
+
+(3) This function is required to resolve an ambiguous overload error, because pairs like `{"key", "value"}` can be both

+# basic_json::string_t
+
+```cpp
+using string_t = StringType;
+```
+
+The type used to store JSON strings.
+
+[RFC 8259](https://tools.ietf.org/html/rfc8259) describes JSON strings as follows:
+> A string is a sequence of zero or more Unicode characters.
+
+To store objects in C++, a type is defined by the template parameter described below. Unicode values are split by the
+JSON class into byte-sized characters during deserialization.
+
+## Template parameters
+
+`StringType`
+: the container to store strings (e.g., `std::string`). Note this container is used for keys/names in objects, see
+ [object_t](object_t.md).
+
+## Notes
+
+#### Default type
+
+With the default values for `StringType` (`std::string`), the default value for `string_t` is `#!cpp std::string`.
+
+#### Encoding
+
+Strings are stored in UTF-8 encoding. Therefore, functions like `std::string::size()` or `std::string::length()` return
+the number of bytes in the string rather than the number of characters or glyphs.
+
+#### String comparison
+
+[RFC 8259](https://tools.ietf.org/html/rfc8259) states:
+> Software implementations are typically required to test names of object members for equality. Implementations that
+> transform the textual representation into sequences of Unicode code units and then perform the comparison numerically,
+> code unit by code unit, are interoperable in the sense that implementations will agree in all cases on equality or
+> inequality of two strings. For example, implementations that compare strings with escaped characters unconverted may
+> incorrectly find that `"a\\b"` and `"a\u005Cb"` are not equal.
+
+This implementation is interoperable as it does compare strings code unit by code unit.
+
+#### Storage
+
+String values are stored as pointers in a `basic_json` type. That is, for any access to string values, a pointer of type
+`string_t*` must be dereferenced.

+# basic_json::unflatten
+
+```cpp
+basic_json unflatten() const;
+```
+
+The function restores the arbitrary nesting of a JSON value that has been flattened before using the
+[`flatten()`](flatten.md) function. The JSON value must meet certain constraints:
+
+1. The value must be an object.
+2. The keys must be JSON pointers (see [RFC 6901](https://tools.ietf.org/html/rfc6901))
+3. The mapped values must be primitive JSON types.
+
+## Return value
+
+the original JSON from a flattened version
+
+## Exceptions
+
+The function can throw the following exceptions:
+
+- Throws [`type_error.314`](../../home/exceptions.md#jsonexceptiontype_error314) if value is not an object
+- Throws [`type_error.315`](../../home/exceptions.md#jsonexceptiontype_error315) if object values are not primitive
+
+## Exception safety
+
+Strong exception safety: if an exception occurs, the original value stays intact.
+
+## Complexity
+
+Linear in the size the JSON value.
+
+## Notes
+
+Empty objects and arrays are flattened by [`flatten()`](flatten.md) to `#!json null` values and can not unflattened to
+their original type. Apart from this example, for a JSON value `j`, the following is always true:
+`#!cpp j == j.flatten().unflatten()`.

+
+// (2)

+ const ValueType& default_value) const;
+```
+
+1. Returns either a copy of an object's element at the specified key `key` or a given default value if no element with
+ key `key` exists.
+
+ The function is basically equivalent to executing
+ ```cpp
+ try {
+ return at(key);

+
+2. Returns either a copy of an object's element at the specified JSON pointer `ptr` or a given default value if no value

+
+Unlike [`operator[]`](operator[].md), this function does not implicitly add an element to the position defined by

+
+## Template parameters
+
+`ValueType`
+: type compatible to JSON values, for instance `#!cpp int` for JSON integer numbers, `#!cpp bool` for JSON booleans,

+
+## Parameters
+
+`key` (in)
+: key of the element to access
+
+`default_value` (in)
+: the value to return if key/ptr found no value
+
+`ptr` (in)

+ the type of the value at `key`
+ - Throws [`type_error.306`](../../home/exceptions.md#jsonexceptiontype_error306) if the JSON value is not an object;

+# Number Handling
+
+This document describes how the library is handling numbers.
+
+## Background
+
+This section briefly summarizes how the JSON specification describes how numbers should be handled.
+
+### JSON number syntax
+
+JSON defines the syntax of numbers as follows:
+
+!!! quote "[RFC 8259](https://tools.ietf.org/html/rfc8259#section-6), Section 6"
+
+ The representation of numbers is similar to that used in most
+ programming languages. A number is represented in base 10 using
+ decimal digits. It contains an integer component that may be
+ prefixed with an optional minus sign, which may be followed by a
+ fraction part and/or an exponent part. Leading zeros are not
+ allowed.
+
+ A fraction part is a decimal point followed by one or more digits.
+
+ An exponent part begins with the letter E in uppercase or lowercase,
+ which may be followed by a plus or minus sign. The E and optional
+ sign are followed by one or more digits.
+
+The following railroad diagram from [json.org](https://json.org) visualizes the number syntax:
+
+
+
+### Number interoperability
+
+On number interoperability, the following remarks are made:
+
+!!! quote "[RFC 8259](https://tools.ietf.org/html/rfc8259#section-6), Section 6"
+
+ This specification allows implementations to set limits on the range
+ and precision of numbers accepted. Since software that implements
+ IEEE 754 binary64 (double precision) numbers [IEEE754] is generally
+ available and widely used, good interoperability can be achieved by
+ implementations that expect no more precision or range than these
+ provide, in the sense that implementations will approximate JSON
+ numbers within the expected precision. A JSON number such as 1E400
+ or 3.141592653589793238462643383279 may indicate potential
+ interoperability problems, since it suggests that the software that
+ created it expects receiving software to have greater capabilities
+ for numeric magnitude and precision than is widely available.
+
+ Note that when such software is used, numbers that are integers and
+ are in the range $[-2^{53}+1, 2^{53}-1]$ are interoperable in the
+ sense that implementations will agree exactly on their numeric
+ values.
+
+## Library implementation
+
+This section describes how the above number specification is implemented by this library.
+
+### Number storage
+
+In the default [`json`](../../api/json.md) type, numbers are stored as `#!c std::uint64_t`, `#!c std::int64_t`, and
+`#!c double`, respectively. Thereby, `#!c std::uint64_t` and `#!c std::int64_t` are used only if they can store the
+number without loss of precision. If this is impossible (e.g., if the number is too large), the number is stored as
+`#!c double`.
+
+!!! info "Notes"
+
+ - Numbers with a decimal digit or scientific notation are always stored as `#!c double`.
+ - The number types can be changed, see [Template number types](#template-number-types).
+ - As of version 3.9.1, the conversion is realized by
+ [`std::strtoull`](https://en.cppreference.com/w/cpp/string/byte/strtoul),
+ [`std::strtoll`](https://en.cppreference.com/w/cpp/string/byte/strtol), and
+ [`std::strtod`](https://en.cppreference.com/w/cpp/string/byte/strtof), respectively.
+
+!!! example "Examples"
+
+ - Integer `#!c -12345678912345789123456789` is smaller than `#!c INT64_MIN` and will be stored as floating-point
+ number `#!c -1.2345678912345788e+25`.
+ - Integer `#!c 1E3` will be stored as floating-point number `#!c 1000.0`.
+
+### Number limits
+
+- Any 64 bit signed or unsigned integer can be stored without loss of precision.
+- Numbers exceeding the limits of `#!c double` (i.e., numbers that after conversion via
+[`std::strtod`](https://en.cppreference.com/w/cpp/string/byte/strtof) are not satisfying
+[`std::isfinite`](https://en.cppreference.com/w/cpp/numeric/math/isfinite) such as `#!c 1E400`) will throw exception
+[`json.exception.out_of_range.406`](../../home/exceptions.md#jsonexceptionout_of_range406) during parsing.
+- Floating-point numbers are rounded to the next number representable as `double`. For instance
+`#!c 3.141592653589793238462643383279` is stored as [`0x400921fb54442d18`](https://float.exposed/0x400921fb54442d18).
+This is the same behavior as the code `#!c double x = 3.141592653589793238462643383279;`.
+
+!!! success "Interoperability"
+
+ - The library interoperable with respect to the specification, because its supported range $[-2^{63}, 2^{64}-1]$ is
+ larger than the described range $[-2^{53}+1, 2^{53}-1]$.
+ - All integers outside the range $[-2^{63}, 2^{64}-1]$, as well as floating-point numbers are stored as `double`.
+ This also concurs with the specification above.
+
+### Zeros
+
+The JSON number grammar allows for different ways to express zero, and this library will store zeros differently:
+
+| Literal | Stored value and type | Serialization |
+| ------- | --------------------- | ------------- |
+| `0` | `#!c std::uint64_t(0)` | `0` |
+| `-0` | `#!c std::int64_t(0)` | `0` |
+| `0.0` | `#!c double(0.0)` | `0.0` |
+| `-0.0` | `#!c double(-0.0)` | `-0.0` |
+| `0E0` | `#!c double(0.0)` | `0.0` |
+| `-0E0` | `#!c double(-0.0)` | `-0.0` |
+
+That is, `-0` is stored as a signed integer, but the serialization does not reproduce the `-`.
+
+### Number serialization
+
+- Integer numbers are serialized as is; that is, no scientific notation is used.
+- Floating-point numbers are serialized as specified by the `#!c %g` printf modifier with
+ [`std::numeric_limits<double>::max_digits10`](https://en.cppreference.com/w/cpp/types/numeric_limits/max_digits10)
+ significant digits). The rationale is to use the shortest representation while still allow round-tripping.
+
+!!! hint "Notes regarding precision of floating-point numbers"
+
+ As described above, floating-point numbers are rounded to the nearest double and serialized with the shortest
+ representation to allow round-tripping. This can yield confusing examples:
+
+ - The serialization can have fewer decimal places than the input: `#!c 2555.5599999999999` will be serialized as
+ `#!c 2555.56`. The reverse can also be true.
+ - The serialization can be in scientific notation even if the input is not: `#!c 0.0000972439793401814` will be
+ serialized as `#!c 9.72439793401814e-05`. The reverse can also be true: `#!c 12345E-5` will be serialized as
+ `#!c 0.12345`.
+ - Conversions from `#!c float` to `#!c double` can also introduce rouding errors:
+ ```cpp
+ float f = 0.3;
+ json j = f;
+ std::cout << j << '\n';
+ ```
+ yields `#!c 0.30000001192092896`.
+
+ All examples here can be reproduced by passing the original double value to
+
+ ```cpp
+ std::printf("%.*g\n", std::numeric_limits<double>::max_digits10, double_value);
+ ```
+
+#### NaN handling
+
+NaN (not-a-number) cannot be expressed with the number syntax described above and are in fact explicitly excluded:
+
+!!! quote "[RFC 8259](https://tools.ietf.org/html/rfc8259#section-6), Section 6"
+
+ Numeric values that cannot be represented in the grammar below (such
+ as Infinity and NaN) are not permitted.
+
+That is, there is no way to *parse* a NaN value. However, NaN values can be stored in a JSON value by assignment.
+
+This library serializes NaN values as `#!js null`. This corresponds to the behavior of JavaScript's
+[`JSON.stringify`](https://www.w3schools.com/js/js_json_stringify.asp) function.
+
+!!! example
+
+ The following example shows how a NaN value is stored in a `json` value.
+
+ ```cpp
+ int main()
+ {
+ double val = std::numeric_limits<double>::quiet_NaN();
+ std::cout << "val=" << val << std::endl;
+ json j = val;
+ std::cout << "j=" << j.dump() << std::endl;
+ val = j;
+ std::cout << "val=" << val << std::endl;
+ }
+ ```
+
+ output:
+
+ ```
+ val=nan
+ j=null
+ val=nan
+ ```
+
+### Number comparison
+
+Floating-point inside JSON values numbers are compared with `#!c json::number_float_t::operator==` which is
+`#!c double::operator==` by default.
+
+!!! example "Alternative comparison functions"
+
+ To compare floating-point while respecting an epsilon, an alternative
+ [comparison function](https://github.com/mariokonrad/marnav/blob/master/include/marnav/math/floatingpoint.hpp#L34-#L39)
+ could be used, for instance
+
+ ```cpp
+ template<typename T, typename = typename std::enable_if<std::is_floating_point<T>::value, T>::type>
+ inline bool is_same(T a, T b, T epsilon = std::numeric_limits<T>::epsilon()) noexcept
+ {
+ return std::abs(a - b) <= epsilon;
+ }
+ ```
+ Or you can self-define an operator equal function like this:
+
+ ```cpp
+ bool my_equal(const_reference lhs, const_reference rhs)
+ {
+ const auto lhs_type lhs.type();
+ const auto rhs_type rhs.type();
+ if (lhs_type == rhs_type)
+ {
+ switch(lhs_type)
+ {
+ // self_defined case
+ case value_t::number_float:
+ return std::abs(lhs - rhs) <= std::numeric_limits<float>::epsilon();
+
+ // other cases remain the same with the original
+ ...
+ }
+ }
+ ...
+ }
+ ```
+
+ (see [#703](https://github.com/nlohmann/json/issues/703) for more information.)
+
+!!! note
+
+ NaN values never compare equal to themselves or to other NaN values. See [#514](https://github.com/nlohmann/json/issues/514).
+
+### Number conversion
+
+Just like the C++ language itself, the `get` family of functions allows conversions between unsigned and signed
+integers, and between integers and floating-point values to integers. This behavior may be surprising.
+
+!!! warning "Unconditional number conversions"
+
+ ```cpp hl_lines="3"
+ double d = 42.3; // non-integer double value 42.3
+ json jd = d; // stores double value 42.3
+ std::int64_t i = jd.get<std::int64_t>(); // now i==42; no warning or error is produced
+ ```
+
+ Note the last line with throw a [`json.exception.type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302)
+ exception if `jd` is not a numerical type, for instance a string.
+
+The rationale is twofold:
+
+1. JSON does not define a number type or precision (see [#json-specification](above)).
+2. C++ also allows to silently convert between number types.
+
+!!! success "Conditional number conversion"
+
+ The code above can be solved by explicitly checking the nature of the value with members such as
+ [`is_number_integer()`](../../api/basic_json/is_number_integer.md) or
+ [`is_number_unsigned()`](../../api/basic_json/is_number_unsigned.md):
+
+ ```cpp hl_lines="2"
+ // check if jd is really integer-valued
+ if (jd.is_number_integer())
+ {
+ // if so, do the conversion and use i
+ std::int64_t i = jd.get<std::int64_t>();
+ // ...
+ }
+ else
+ {
+ // otherwise, take appropriate action
+ // ...
+ }
+ ```
+
+ Note this approach also has the advantage that it can react on non-numerical JSON value types such as strings.
+
+ (Example taken from [#777](https://github.com/nlohmann/json/issues/777#issuecomment-459968458).)
+
+### Determine number types
+
+As the example in [Number conversion](#number_conversion) shows, there are different functions to determine the type of
+the stored number:
+
+- [`is_number()`](../../api/basic_json/is_number.md) returns `#!c true` for any number type
+- [`is_number_integer()`](../../api/basic_json/is_number_integer.md) returns `#!c true` for signed and unsigned integers
+- [`is_number_unsigned()`](../../api/basic_json/is_number_unsigned.md) returns `#!c true` for unsigned integers only
+- [`is_number_float()`](../../api/basic_json/is_number_float.md) returns `#!c true` for floating-point numbers
+- [`type_name()`](../../api/basic_json/type_name.md) returns `#!c "number"` for any number type
+- [`type()`](../../api/basic_json/type.md) returns an different enumerator of
+ [`value_t`](../../api/basic_json/value_t.md) for all number types
+
+| function | unsigned integer | signed integer | floating-point | string |
+| -------- | ---------------- | -------------- | -------------- | ------ |
+| [`is_number()`](../../api/basic_json/is_number.md) | `#!c true` | `#!c true` | `#!c true` | `#!c false` |
+| [`is_number_integer()`](../../api/basic_json/is_number_integer.md) | `#!c true` | `#!c true` | `#!c false` | `#!c false` |
+| [`is_number_unsigned()`](../../api/basic_json/is_number_unsigned.md) | `#!c true` | `#!c false` | `#!c false` | `#!c false` |
+| [`is_number_float()`](../../api/basic_json/is_number_float.md) | `#!c false` | `#!c false` | `#!c true` | `#!c false` |
+| [`type_name()`](../../api/basic_json/type_name.md) | `#!c "number"` | `#!c "number"` | `#!c "number"` | `#!c "string"` |
+| [`type()`](../../api/basic_json/type.md) | `number_unsigned` | `number_integer` | `number_float` | `string` |
+
+### Template number types
+
+The number types can be changed with template parameters.
+
+| position | number type | default type | possible values |
+| -------- | ----------- | ------------ | --------------- |
+| 5 | signed integers | `#!c std::int64_t` | `#!c std::int32_t`, `#!c std::int16_t`, etc. |
+| 6 | unsigned integers | `#!c std::uint64_t` | `#!c std::uint32_t`, `#!c std::uint16_t`, etc. |
+| 7 | floating-point | `#!c double` | `#!c float`, `#!c long double` |
+
+!!! info "Constraints on number types"
+
+ - The type for signed integers must be convertible from `#!c long long`. The type for floating-point numbers is used
+ in case of overflow.
+ - The type for unsigned integers must be convertible from `#!c unsigned long long`. The type for floating-point
+ numbers is used in case of overflow.
+ - The types for signed and unsigned integers must be distinct, see
+ [#2573](https://github.com/nlohmann/json/issues/2573).
+ - Only `#!c double`, `#!c float`, and `#!c long double` are supported for floating-point numbers.
+
+!!! example
+
+ A `basic_json` type that uses `#!c long double` as floating-point type.
+
+ ```cpp hl_lines="2"
+ using json_ld = nlohmann::basic_json<std::map, std::vector, std::string, bool,
+ std::int64_t, std::uint64_t, long double>;
+ ```
+
+ Note values should then be parsed with `json_ld::parse` rather than `json::parse` as the latter would parse
+ floating-point values to `#!c double` before then converting them to `#!c long double`.

+
+### Extended diagnostic messages
+
+Exceptions in the library are thrown in the local context of the JSON value they are detected. This makes detailed diagnostics messages, and hence debugging, difficult.
+
+??? example
+
+ ```cpp
+ --8<-- "examples/diagnostics_standard.cpp"
+ ```
+
+ Output:
+
+ ```
+ --8<-- "examples/diagnostics_standard.output"
+ ```
+
+ This exception can be hard to debug if storing the value `#!c "12"` and accessing it is further apart.
+
+To create better diagnostics messages, each JSON value needs a pointer to its parent value such that a global context (i.e., a path from the root value to the value that lead to the exception) can be created. That global context is provided as [JSON Pointer](../features/json_pointer.md).
+
+As this global context comes at the price of storing one additional pointer per JSON value and runtime overhead to maintain the parent relation, extended diagnostics are disabled by default. They can, however, be enabled by defining the preprocessor symbol [`JSON_DIAGNOSTICS`](../features/macros.md#json_diagnostics) to `1` before including `json.hpp`.
+
+??? example
+
+ ```cpp
+ --8<-- "examples/diagnostics_extended.cpp"
+ ```
+
+ Output:
+
+ ```
+ --8<-- "examples/diagnostics_extended.output"
+ ```
+
+ Now the exception message contains a JSON Pointer `/address/housenumber` that indicates which value has the wrong type.

# Frequently Asked Questions (FAQ)
+## Known bugs
+
+### Brace initialization yields arrays
+
+!!! question
+
+ Why does
+
+ ```cpp
+ json j{true};
+ ```
+
+ and
+
+ ```cpp
+ json j(true);
+ ```
+
+ yield different results (`#!json [true]` vs. `#!json true`)?
+
+This is a known issue, and -- even worse -- the behavior differs between GCC and Clang. The "culprit" for this is the library's constructor overloads for initializer lists to allow syntax like
+
+```cpp
+json array = {1, 2, 3, 4};
+```
+
+for arrays and
+
+```cpp
+json object = {{"one", 1}, {"two", 2}};
+```
+
+for objects.
+
+!!! tip
+
+ To avoid any confusion and ensure portable code, **do not** use brace initialization with the types `basic_json`, `json`, or `ordered_json` unless you want to create an object or array as shown in the examples above.
+
## Limitations

### Parse errors reading non-ASCII characters
@@ -32,13 +70,63 @@
In most cases, the parser is right to complain, because the input is not UTF-8 encoded. This is especially true for Microsoft Windows where Latin-1 or ISO 8859-1 is often the standard encoding.
+### Wide string handling
+
+!!! question
+
+ Why are wide strings (e.g., `std::wstring`) dumped as arrays of numbers?
+
+As described [above](#parse-errors-reading-non-ascii-characters), the library assumes UTF-8 as encoding. To store a wide string, you need to change the encoding.
+
+!!! example
+
+ ```cpp
+ #include <codecvt> // codecvt_utf8
+ #include <locale> // wstring_convert
+
+ // encoding function
+ std::string to_utf8(std::wstring& wide_string)
+ {
+ static std::wstring_convert<std::codecvt_utf8<wchar_t>> utf8_conv;
+ return utf8_conv.to_bytes(wide_string);
+ }
+
+ json j;
+ std::wstring ws = L"車B1234 こんにちは";
+
+ j["original"] = ws;
+ j["encoded"] = to_utf8(ws);
+
+ std::cout << j << std::endl;
+ ```
+
+ The result is:
+
+ ```json
+ {
+ "encoded": "車B1234 こんにちは",
+ "original": [36554, 66, 49, 50, 51, 52, 32, 12371, 12435, 12395, 12385, 12399]
+ }
+ ```
+
+## Exceptions
+
+### Parsing without exceptions
+
+!!! question
+
+ Is it possible to indicate a parse error without throwing an exception?
+
+Yes, see [Parsing and exceptions](../features/parsing/parse_exceptions.md).
+
+
### Key name in exceptions
!!! question
Can I get the key of the object item that caused an exception?
-No, this is not possible. See <https://github.com/nlohmann/json/issues/932> for a longer discussion.
+Yes, you can. Please define the symbol [`JSON_DIAGNOSTICS`](../features/macros.md#json_diagnostics) to get [extended diagnostics messages](exceptions.md#extended-diagnostic-messages).

+@brief the JSON type enumeration

+distinguish the stored values, and the functions @ref basic_json::is_null(),
+@ref basic_json::is_object(), @ref basic_json::is_array(),
+@ref basic_json::is_string(), @ref basic_json::is_boolean(),
+@ref basic_json::is_number() (with @ref basic_json::is_number_integer(),
+@ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),
+@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
+@ref basic_json::is_structured() rely on it.
+
+@note There are three enumeration entries (number_integer, number_unsigned, and
+number_float), because the library distinguishes these three types for numbers:
+@ref basic_json::number_unsigned_t is used for unsigned integers,
+@ref basic_json::number_integer_t is used for signed integers, and
+@ref basic_json::number_float_t is used for floating-point numbers or to
+approximate integers which do not fit in the limits of their respective type.
+

+value with the default value for a given type

-@ref basic_json::is_string(), @ref basic_json::is_boolean(),

-@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
-@ref basic_json::is_structured() rely on it.
-
-@note There are three enumeration entries (number_integer, number_unsigned, and
-number_float), because the library distinguishes these three types for numbers:
-@ref basic_json::number_unsigned_t is used for unsigned integers,
-@ref basic_json::number_integer_t is used for signed integers, and
-@ref basic_json::number_float_t is used for floating-point numbers or to
-approximate integers which do not fit in the limits of their respective type.

- // line counter that counts only 0x0a bytes, but it would still be
- // processed as a line feed by an unsafe UTF-8 decoder later in the

- // sequences means also, that ASCII characters are *only* allowed to be

- // can remain a potential security risk, depending on what use is made of
- // these codes subsequently. Examples of such internal use:
- //
- // - Some file APIs with 16-bit characters may use the integer value -1
- // = U+FFFF to signal an end-of-file (EOF) or error condition.
- //
- // - In some UTF-16 receivers, code point U+FFFE might trigger a

+# GDB Pretty Printer
+
+File [nlohmann-json.py](nlohmann-json.py) contains a pretty printer for GDB for JSON values of this library. It was originally published as [Gist](https://gist.github.com/ssbssa/60da5339c6e6036b2afce17de06050ea#file-nlohmann-json-py) by [Hannes Domani](https://github.com/ssbssa).
+
+## How to use
+
+- Add line
+
+ ```
+ source /path/to/nlohmann-json.py
+ ```
+
+ to `~/.gdbinit`. Note you must replace `/path/to` with whatever path you stored file `nlohmann-json.py`.
+- In GDB, debug as usual. When you want to pretty-print a JSON value `var`, type
+
+ ```
+ p -pretty on -array on -- var
+ ```
+
+ The result should look like
+
+ ```
+ $1 = std::map with 5 elements = {
+ ["Baptiste"] = std::map with 1 element = {
+ ["first"] = "second"
+ },
+ ["Emmanuel"] = std::vector of length 3, capacity 3 = {
+ 3,
+ "25",
+ 0.5
+ },
+ ["Jean"] = 0.7,
+ ["Zorg"] = std::map with 8 elements = {
+ ["array"] = std::vector of length 3, capacity 3 = {
+ 1,
+ 0,
+ 2
+ },
+ ["awesome_str"] = "bleh",
+ ["bool"] = true,
+ ["flex"] = 0.2,
+ ["float"] = 5.22,
+ ["int"] = 5,
+ ["nested"] = std::map with 1 element = {
+ ["bar"] = "barz"
+ },
+ ["trap "] = "you fell"
+ },
+ ["empty"] = nlohmann::detail::value_t::null
+ }
+ ```
+
+Tested with GDB 9.2. See [#1952](https://github.com/nlohmann/json/issues/1952) for more information. Please post questions there.
