Clang Flake Template
This is a template for constructing a working environment for C/C++ development
with the clang (version 16.0.6) toolchain. direnv
can be used to launch a dev shell upon entering this directory (refer to
.envrc). Otherwise run via:
$ nix develop
Building
We use CMake (version 3.27.7) to build the project. When first starting the project, we recommend running the following commands:
$ mkdir -p build/{Debug,Release}
$ (cd build/Debug && cmake -DCMAKE_BUILD_TYPE=Debug ../..)
$ (cd build/Release && cmake -DCMAKE_BUILD_TYPE=Release ../..)
This will create a CMake cache file in each subdirectory with the build types
set. Now you can build a Debug or Release variant by navigating to the
corresponding subdirectory and running:
$ cmake --build .
Language Server
The clangd LSP (version 14.0.6) is included in this flake. The codelldb VSCode plugin is also included to interface with the LSP. Note this plugin, despite its name, is compatible with other editors (e.g. neovim). To configure, refer to your editor's documentation.
To use the LSP across files, a
compilation database
must be generated. The CMakeLists.txt file already enables this in the Debug
configuration type. A top-level compile_commands.json symbolic link already
exists and points to this generated database.
Documentation
Documentation is generated using Doxygen
(version 1.9.7). (Re)generate documentation by editing the Doxyfile and
running:
$ doxygen
Testing
We use CTest (version
3.27.7) for unit testing. To run the tests, navigate to build/Debug and type
the following:
$ cmake --build .
$ make test
Formatting
Formatting depends on the clang-format
(version 14.0.6) tool. Refer to .clang-format for default formatting options.
A pre-commit hook is included in .githooks that can be used to format all
*.c(pp)? and *.h(pp)? files prior to commit. Install via:
$ git config --local core.hooksPath .githooks/
If running direnv, this hook is installed automatically when entering the directory.
