===============================================================================
ALE C Integration *ale-c-options*
===============================================================================
Global Options
g:ale_c_build_dir_names *g:ale_c_build_dir_names*
*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)
g:ale_c_parse_makefile *g:ale_c_parse_makefile*
*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.
===============================================================================
clang *ale-c-clang*
g:ale_c_clang_executable *g:ale_c_clang_executable*
*b:ale_c_clang_executable*
Type: |String|
Default: `'clang'`
This variable can be changed to use a different executable for clang.
g:ale_c_clang_options *g:ale_c_clang_options*
*b:ale_c_clang_options*
Type: |String|
Default: `'-std=c11 -Wall'`
This variable can be changed to modify flags given to clang.
===============================================================================
clang-format *ale-c-clangformat*
g:ale_c_clangformat_executable *g:ale_c_clangformat_executable*
*b:ale_c_clangformat_executable*
Type: |String|
Default: `'clang-format'`
This variable can be changed to use a different executable for clang-format.
g:ale_c_clangformat_options *g:ale_c_clangformat_options*
*b:ale_c_clangformat_options*
Type: |String|
Default: `''`
This variable can be change to modify flags given to clang-format.
===============================================================================
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:
http://clang.llvm.org/extra/clang-tidy/checks/list.html
g:ale_c_clangtidy_executable *g:ale_c_clangtidy_executable*
*b:ale_c_clangtidy_executable*
Type: |String|
Default: `'clang-tidy'`
This variable can be changed to use a different executable for clangtidy.
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.
===============================================================================
cppcheck *ale-c-cppcheck*
g:ale_c_cppcheck_executable *g:ale_c_cppcheck_executable*
*b:ale_c_cppcheck_executable*
Type: |String|
Default: `'cppcheck'`
This variable can be changed to use a different executable for cppcheck.
g:ale_c_cppcheck_options *g:ale_c_cppcheck_options*
*b:ale_c_cppcheck_options*
Type: |String|
Default: `'--enable=style'`
This variable can be changed to modify flags given to cppcheck.
===============================================================================
flawfinder *ale-c-flawfinder*
g:ale_c_flawfinder_executable *g:ale_c_flawfinder_executable*
*b:ale_c_flawfinder_executable*
Type: |String|
Default: `'flawfinder'`
This variable can be changed to use a different executable for flawfinder.
g:ale_c_flawfinder_minlevel *g:ale_c_flawfinder_minlevel*
*b:ale_c_flawfinder_minlevel*
Type: |Number|
Default: `1`
This variable can be changed to ignore risks under the given risk threshold.
g:ale_c_flawfinder_options *g:ale-c-flawfinder*
*b:ale-c-flawfinder*
Type: |String|
Default: `''`
This variable can be used to pass extra options into the flawfinder command.
g:ale_c_flawfinder_error_severity *g:ale_c_flawfinder_error_severity*
*b:ale_c_flawfinder_error_severity*
Type: |Number|
Default: `6`
This variable can be changed to set the minimum severity to be treated as an
error. This setting also applies to flawfinder for c++.
===============================================================================
gcc *ale-c-gcc*
g:ale_c_gcc_executable *g:ale_c_gcc_executable*
*b:ale_c_gcc_executable*
Type: |String|
Default: `'gcc'`
This variable can be changed to use a different executable for gcc.
g:ale_c_gcc_options *g:ale_c_gcc_options*
*b:ale_c_gcc_options*
Type: |String|
Default: `'-std=c11 -Wall'`
This variable can be change to modify flags given to gcc.
