"ALE
"How can I configure my C or C++ project? The structure of C and C++
"projects varies wildly from project to project, with many different build
"tools being used for building them, and many different formats for project
"configuration files. ALE can run compilers easily, but ALE cannot easily
"detect which compiler flags to use.
"
"Some tools and build configurations can generate compile_commands.json files.
"The cppcheck, clangcheck, clangtidy and cquery linters can read these files
"for automatically determining the appropriate compiler flags to use.
"
"For linting with compilers like gcc and clang, and with other tools, you will
"need to tell ALE which compiler flags to use yourself. You can use different
"options for different projects with the g:ale_pattern_options setting.
"Consult the documentation for that setting for more information.
"b:ale_linters can be used to select which tools you want to run, say if you
"want to use only gcc for one project, and only clang for another.
"
"ALE will attempt to parse compile_commands.json files to discover compiler
"flags to use when linting code. See :help g:ale_c_parse_compile_commands for
"more information. See Clang's documentation for compile_commands.json files.
"You should strongly consider generating them in your builds, which is easy to
"do with CMake.
"
"You can also configure ALE to automatically run make -n to run dry runs on
"Makefiles to discover compiler flags. This can execute arbitrary code, so the
"option is disabled by default. See :help g:ale_c_parse_makefile.
"
"You may also configure buffer-local settings for linters with
"project-specific vimrc files. local_vimrc can be used for executing local
"vimrc files which can be shared in your project.
