@ -25,13 +25,28 @@ g:ale_c_build_dir *g:ale_c_build_dir*
Type: |String|
Default: `''`
A path to the directory containing the `compile_commands.json` file to use
with c-family linters. Usually setting this option to a non-empty string
will override the |g:ale_c_build_dir_names| option to impose a compilation
database (it can be useful if multiple builds are in multiple build
subdirectories in the project tree).
This feature is also most useful for the clang tools linters, wrapped
around LibTooling (namely clang-tidy here)
For programs that can read `compile_commands.json` files, this option can be
set to the directory containing the file for the project. ALE will try to
determine the location of `compile_commands.json` automatically, but if your
file exists in some other directory, you can set this option so ALE will
know where it is.
This directory will be searched instead of |g:ale_c_build_dir_names|.
g:ale_c_parse_compile_commands *g:ale_c_parse_compile_commands*
*b:ale_c_parse_compile_commands*
Type: |Number|
Default: `0`
If set to `1`, ALE will parse `compile_commands.json` files to automatically
determine flags for C or C++ compilers. ALE will first search for the
nearest `compile_commands.json` file, and then look for
`compile_commands.json` files in the directories for
|g:ale_c_build_dir_names|.
If |g:ale_c_parse_makefile| or |b:ale_c_parse_makefile| is set to `1`, the
output of `make -n` will be preferred over `compile_commands.json` files.
