ALE C++ Integration                                           *ale-cpp-options*

For basic checking of problems with C++ files, ALE offers the `cc` linter,
which runs either `clang++`, or `gcc`. See |ale-cpp-cc|.


===============================================================================
Global Options

The following C options also apply to some C++ linters too.

* |g:ale_c_always_make|
* |g:ale_c_build_dir_names|
* |g:ale_c_build_dir|
* |g:ale_c_parse_makefile|
* |g:ale_c_parse_compile_commands|


===============================================================================
astyle                                                         *ale-cpp-astyle*

g:ale_cpp_astyle_executable                       *g:ale_cpp_astyle_executable*
                                                  *b:ale_cpp_astyle_executable*
  Type: |String|
  Default: `'astyle'`

  This variable can be changed to use a different executable for astyle.


g:ale_cpp_astyle_project_options             *g:ale_cpp_astyle_project_options*
                                             *b:ale_cpp_astyle_project_options*
  Type: |String|
  Default: `''`

  This variable can be changed to use an option file for project level
  configurations. Provide only the filename of the option file that should be
  present at the project's root directory.

  For example, if .astylrc is specified, the file is searched in the parent
  directories of the source file's directory.


===============================================================================
cc                                                                 *ale-cpp-cc*
                                                                  *ale-cpp-gcc*
                                                                *ale-cpp-clang*

g:ale_cpp_cc_executable                               *g:ale_cpp_cc_executable*
                                                      *b:ale_cpp_cc_executable*
  Type: |String|
  Default: `'<auto>'`

  This variable can be changed to use a different executable for a C++ compiler.

  ALE will try to use `clang++` if Clang is available, otherwise ALE will
  default to checking C++ code with `gcc`.


g:ale_cpp_cc_options                                     *g:ale_cpp_cc_options*
                                                         *b:ale_cpp_cc_options*
  Type: |String|
  Default: `'-std=c++14 -Wall'`

  This variable can be changed to modify flags given to the C++ compiler.


g:ale_cpp_cc_use_header_lang_flag           *g:ale_cpp_cc_use_header_lang_flag*
                                            *b:ale_cpp_cc_use_header_lang_flag*
  Type: |Number|
  Default: `-1`

  By default, ALE will use `'-x c++-header'` instead of `'-x c++'` for header
  files when using Clang.

  This variable can be changed to manually activate or deactivate this flag
  for header files.

  - When set to `-1`, the default beviour is used, `'-x c++-header'` is used with
    Clang and `'-x c++'` is used with other compilers.
  - When set to `0`, the flag is deactivated, `'-x c++'` is always used
    independently of the compiler.
  - When set to `1`, the flag is activated, `'-x c++-header'` is always used
    independently of the compiler.

  Gcc does not support `'-x c++-header'` when using `'-'` as input filename,
  which is what ALE does. This why, by default, ALE only uses `'-x c++-header'`
  with Clang.


g:ale_cpp_cc_header_exts                             *g:ale_cpp_cc_header_exts*
                                                     *b:ale_cpp_cc_header_exts*
  Type: |List|
  Default: `['h', 'hpp']`

  This variable can be changed to modify the list of extensions of the files
  considered as header files.

  This variable is only used when `'-x c++-header'` is used instead of `'-x c++'`,
  see |g:ale_cpp_cc_use_header_lang_flag|.


===============================================================================
ccls                                                             *ale-cpp-ccls*

g:ale_cpp_ccls_executable                           *g:ale_cpp_ccls_executable*
                                                    *b:ale_cpp_ccls_executable*
  Type: |String|
  Default: `'ccls'`

  This variable can be changed to use a different executable for ccls.


g:ale_cpp_ccls_init_options                       *g:ale_cpp_ccls_init_options*
                                                  *b:ale_cpp_ccls_init_options*
  Type: |Dictionary|
  Default: `{}`

  This variable can be changed to customize ccls initialization options.
  Example: >
      {
    \   'cacheDirectory': '/tmp/ccls',
    \   'cacheFormat': 'binary',
    \   'diagnostics': {
    \     'onOpen': 0,
    \     'opChange': 1000,
    \   },

clangcheck                                                 *ale-cpp-clangcheck*

`clang-check` 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-check` 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_cpp_clangcheck_executable               *g:ale_cpp_clangcheck_executable*
                                              *b:ale_cpp_clangcheck_executable*
  Type: |String|
  Default: `'clang-check'`

  This variable can be changed to use a different executable for clangcheck.


g:ale_cpp_clangcheck_options                     *g:ale_cpp_clangcheck_options*
                                                 *b:ale_cpp_clangcheck_options*
  Type: |String|
  Default: `''`

  This variable can be changed to modify flags given to clang-check.

  This variable should not be set to point to build subdirectory with
  `-p path/to/build` option, as it is handled by the |g:ale_c_build_dir|
  option.


===============================================================================
clangd                                                         *ale-cpp-clangd*

g:ale_cpp_clangd_executable                       *g:ale_cpp_clangd_executable*
                                                  *b:ale_cpp_clangd_executable*
  Type: |String|
  Default: `'clangd'`

  This variable can be changed to use a different executable for clangd.


g:ale_cpp_clangd_options                             *g:ale_cpp_clangd_options*
                                                     *b:ale_cpp_clangd_options*
  Type: |String|
  Default: `''`

  This variable can be changed to modify flags given to clangd.


===============================================================================
clang-format                                              *ale-cpp-clangformat*

See |ale-c-clangformat| for information about the available options.
Note that the C options are also used for C++.


===============================================================================
clangtidy                                                   *ale-cpp-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_cpp_clangtidy_checks                         *g:ale_cpp_clangtidy_checks*
                                                   *b:ale_cpp_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.


g:ale_cpp_clangtidy_executable                 *g:ale_cpp_clangtidy_executable*
                                               *b:ale_cpp_clangtidy_executable*
  Type: |String|
  Default: `'clang-tidy'`

  This variable can be changed to use a different executable for clangtidy.


g:ale_cpp_clangtidy_options                       *g:ale_cpp_clangtidy_options*
                                                  *b:ale_cpp_clangtidy_options*
  Type: |String|
  Default: `''`

  This variable can be changed to modify compiler 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.


g:ale_cpp_clangtidy_extra_options           *g:ale_cpp_clangtidy_extra_options*
                                            *b:ale_cpp_clangtidy_extra_options*
  Type: |String|
  Default: `''`

  This variable can be changed to modify flags given to clang-tidy.


g:ale_cpp_clangtidy_fix_errors                 *g:ale_cpp_clangtidy_fix_errors*
                                               *b:ale_cpp_clangtidy_fix_errors*
  Type: |Number|
  Default: `1`

  This variable can be changed to disable the `-fix-errors` option for the
  |clangtidy| fixer.


===============================================================================
clazy                                                           *ale-cpp-clazy*

  Type: |String|
  Default: `'clazy-standalone'`

  This variable can be changed to use a different executable for clazy.

                                                       *b:ale_cpp_clazy_checks*
  Type: |List|
  Default: `['level1']`

  The checks to enable for clazy 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.


g:ale_cpp_clazy_options                               *g:ale_cpp_clazy_options*
                                                      *b:ale_cpp_clazy_options*
