*b:ale_c_build_dir_names*
|
|
|
|
Type: |List|
|
|
Default: `['build', 'bin']`
|
|
|
|
A list of directory names to be used when searching upwards from cpp
|
|
files to discover compilation databases with. For directory named `'foo'`,
|
|
ALE will search for `'foo/compile_commands.json'` in all directories on and above
|
|
the directory containing the cpp file to find path to compilation database.
|
|
This feature is useful for the clang tools wrapped around LibTooling (namely
|
|
here, clang-tidy)

g:ale_c_build_dir *g:ale_c_build_dir*
|
|
*b: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)

*b:ale_c_parse_makefile*

Type: |Number|
|
|
Default: `0`
|
|
|
|
If set to `1`, ALE will run `make -n` to automatically determine flags to
|
|
set for C or C++ compilers. This can make it easier to determine the correct
|
|
build flags to use for different files.

clangtidy *ale-c-clangtidy*
|
|
|
|
`clang-tidy` will be run only when files are saved to disk, so that
|
|
`compile_commands.json` files can be used. It is recommended to use this
|
|
linter in combination with `compile_commands.json` files.
|
|
Therefore, `clang-tidy` linter reads the options |g:ale_c_build_dir| and
|
|
|g:ale_c_build_dir_names|. Also, setting |g:ale_c_build_dir| actually
|
|
overrides |g:ale_c_build_dir_names|.
|
|
|
|
|
|
g:ale_c_clangtidy_checks *g:ale_c_clangtidy_checks*
|
|
*b:ale_c_clangtidy_checks*
|
|
Type: |List|
|
|
Default: `['*']`
|
|
|
|
The checks to enable for clang-tidy with the `-checks` argument.
|
|
|
|
All options will be joined with commas, and escaped appropriately for
|
|
the shell. The `-checks` flag can be removed entirely by setting this
|
|
option to an empty List.
|
|
|
|
Not all of clangtidy checks are applicable for C. You should consult the
|
|
clang documentation for an up-to-date list of compatible checks:

g:ale_c_clangtidy_options *g:ale_c_clangtidy_options*
|
|
*b:ale_c_clangtidy_options*
|
|
Type: |String|
|
|
Default: `''`
|
|
|
|
This variable can be changed to modify flags given to clang-tidy.
|
|
|
|
- Setting this variable to a non-empty string,
|
|
- and working in a buffer where no compilation database is found using
|
|
|g:ale_c_build_dir_names| or |g:ale_c_build_dir|,
|
|
will cause the `--` argument to be passed to `clang-tidy`, which will mean
|
|
that detection of `compile_commands.json` files for compile command
|
|
databases will be disabled.
|
|
Only set this option if you want to control compiler flags
|
|
entirely manually, and no `compile_commands.json` file is in one
|
|
of the |g:ale_c_build_dir_names| directories of the project tree.
