Export of internal Abseil changes -- 9f746b79e16d36dba908ed9e2a586d890fe54acc by Derek Mauro <dmauro@google.com>: Remove the Bazel mirror URL that we use in our WORKSPACE file This doesn't appear to be supported. We use --distdir caching in our tests. PiperOrigin-RevId: 327634738 -- e1f6f54830c415fc8bb8dc14483fae4cf9713d75 by Abseil Team <absl-team@google.com>: Removing comments following license() rules as they are rarely useful, redundant with LICENSE files, and tend to fall out of date. PiperOrigin-RevId: 327504063 -- b59c076638a57a74a3f8475f1dee8b536e32a15f by Gennadiy Rozental <rogeeff@google.com>: Change GetAllFlags API to return a collection of mutable flag handles. This will make this interface on par with FindCommandLineFlag and allow to call CommandLineFlag::ParseFrom on the handle returned by GetAllFlags. PiperOrigin-RevId: 327499084 -- bbf56b3c4a1d908d95e5a52aba38b1984151efff by Gennadiy Rozental <rogeeff@google.com>: Make raw_hash_set compile when AllocTraits::propagate_on_container_swap is false. PiperOrigin-RevId: 327371107 -- 837f62c85ea65c1d6b847a75816198c625fe62ff by Abseil Team <absl-team@google.com>: On macOS, `mem_alloc` is defined like this: rpc/types.h:86:#define mem_alloc(bsize) calloc(1, bsize) So if that file is included before container_memory.h, the variable mem_alloc may never get defined. This is fixed by using a different name. PiperOrigin-RevId: 327360224 -- aa8f5528382c0d01239ce75b645723aaf7e1ef46 by Gennadiy Rozental <rogeeff@google.com>: Release of absl::GetAllFlags API. PiperOrigin-RevId: 327275943 GitOrigin-RevId: 9f746b79e16d36dba908ed9e2a586d890fe54acc Change-Id: I99c5c87dd1712bf8df9a52397b0c1e400a3c3447
The repository contains the Abseil C++ library code. Abseil is an open-source collection of C++ code (compliant to C++11) designed to augment the C++ standard library.
Abseil is an open-source collection of C++ library code designed to augment the C++ standard library. The Abseil library code is collected from Google's own C++ code base, has been extensively tested and used in production, and is the same code we depend on in our daily coding lives.
In some cases, Abseil provides pieces missing from the C++ standard; in others, Abseil provides alternatives to the standard for special needs we've found through usage in the Google code base. We denote those cases clearly within the library code we provide you.
Abseil is not meant to be a competitor to the standard library; we've just found that many of these utilities serve a purpose within our code base, and we now want to provide those resources to the C++ community as a whole.
If you want to just get started, make sure you at least run through the Abseil Quickstart. The Quickstart contains information about setting up your development environment, downloading the Abseil code, running tests, and getting a simple binary working.
Bazel is the official build system for Abseil, which is supported on most major platforms (Linux, Windows, macOS, for example) and compilers. See the quickstart for more information on building Abseil using the Bazel build system.
If you require CMake support, please check the CMake build instructions.
Abseil contains the following C++ library components:
base Abseil Fundamentals base library contains initialization code and other code which all other Abseil code depends on. Code within base may not depend on any other code (other than the C++ standard library).algorithm algorithm library contains additions to the C++ <algorithm> library and container-based versions of such algorithms.container container library contains additional STL-style containers, including Abseil's unordered “Swiss table” containers.debugging debugging library contains code useful for enabling leak checks, and stacktrace and symbolization utilities.hash hash library contains the hashing framework and default hash functor implementations for hashable types in Abseil.memory memory library contains C++11-compatible versions of std::make_unique() and related memory management facilities.meta meta library contains C++11-compatible versions of type checks available within C++14 and C++17 versions of the C++ <type_traits> library.numeric numeric library contains C++11-compatible 128-bit integers.strings strings library contains a variety of strings routines and utilities, including a C++11-compatible version of the C++17 std::string_view type.synchronization synchronization library contains concurrency primitives (Abseil's absl::Mutex class, an alternative to std::mutex) and a variety of synchronization abstractions.time time library contains abstractions for computing with absolute points in time, durations of time, and formatting and parsing time within time zones.types types library contains non-container utility types, like a C++11-compatible version of the C++17 std::optional type.utility utility library contains utility and helper code.The Abseil C++ library is licensed under the terms of the Apache license. See LICENSE for more information.
