Follow either the CMake (recommended) or Compilation Database instructions below to create the appropriate project description file in the fuchsia directory.
Then in CLion choose Import Project from Sources and select the fuchsia directory.
To improve performance you probably want to exclude directories you are not working with. You can do that in the Project View by right-clicking each directory and choosing Mark directory as->Excluded.
See Helpful Vim tools for Fuchsia development.
There are multiple vscode setups known to work to different degrees. The sections below describe the different setups (pick one).
Install vscode-clangd. Disable the default C/C++ extension if you have it installed.
In settings, add:
"clangd.path": "<absolute path to Fuchsia checkout>/buildtools/linux-x64/clang/bin/clangd",
Finally, follow the Compilation Database instructions below to generate the compile_commands.json in the fuchsia directory. Then reload vscode to enjoy the results.
Install the default C/C++ extension suggested by vscode.
You can use tasks to configure a compilation step.
There are two ways of describing a project's source files that can be used with fuchsia - CMake or Compilation Database. They are described below.
Note these approaches are only intended to help the IDE find and parse the source files. Building should still be done with fx full-build.
The fuchsia.cmake file located in this directory can be used with IDEs that support CMake to include most of the fuchsia source files.
To use, create a CMakeLists.txt file in the top-level fuchsia directory with the following contents. Then use it normally with your IDE.
cmake_minimum_required(VERSION 3.9)
include(${PROJECT_SOURCE_DIR}/docs/development/languages/c-cpp/fuchsia.cmake)
A Compilation Database file can be generated using fx compdb (or fx compdb -z to also include Zircon sources). This will create/update the file compile_commands.json in the fuchsia directory.
When you add, delete, or rename source files the command needs to be rerun to update the compile_commands.json file.
