OPTIONS:

Generic Options:

  -help                         - Display available options (-help-hidden for more)
  -version                      - Display the version of this program

clang-tidy options:

  -checks=<string>              -
                                  Comma-separated list of globs with optional '-'
                                  prefix. Globs are processed in order of
                                  appearance in the list. Globs without '-'
                                  prefix add checks with matching names to the
                                  set, globs with the '-' prefix remove checks
                                  with matching names from the set of enabled
                                  checks. This option's value is appended to the
                                  value of the 'Checks' option in .clang-tidy
                                  file, if any.
  -config=<string>              -
                                  Specifies a configuration in YAML/JSON format:
                                    -config="{Checks: '*',
                                              CheckOptions: [{key: x,
                                                              value: y}]}"
                                  When the value is empty, clang-tidy will
                                  attempt to find a file named .clang-tidy for
                                  each source file in its parent directories.
  -dump-config                  -
                                  Dumps configuration in the YAML format to
                                  stdout. This option can be used along with a
                                  file name (and '--' if the file is outside of a
                                  project with configured compilation database).
                                  The configuration used for this file will be
                                  printed.
                                  Use along with -checks=* to include
                                  configuration of all checks.
  -enable-check-profile         -
                                  Enable per-check timing profiles, and print a
                                  report to stderr.
  -explain-config               -
                                  For each enabled check explains, where it is
                                  enabled, i.e. in clang-tidy binary, command
                                  line or a specific configuration file.
  -export-fixes=<filename>      -
                                  YAML file to store suggested fixes in. The
                                  stored fixes can be applied to the input source
                                  code with clang-apply-replacements.
  -extra-arg=<string>           - Additional argument to append to the compiler command line
  -extra-arg-before=<string>    - Additional argument to prepend to the compiler command line
  -fix                          -
                                  Apply suggested fixes. Without -fix-errors
                                  clang-tidy will bail out if any compilation
                                  errors were found.
  -fix-errors                   -
                                  Apply suggested fixes even if compilation
                                  errors were found. If compiler errors have
                                  attached fix-its, clang-tidy will apply them as
                                  well.
  -format-style=<string>        -
                                  Style for formatting code around applied fixes:
                                    - 'none' (default) turns off formatting
                                    - 'file' (literally 'file', not a placeholder)
                                      uses .clang-format file in the closest parent
                                      directory
                                    - '{ <json> }' specifies options inline, e.g.
                                      -format-style='{BasedOnStyle: llvm, IndentWidth: 8}'
                                    - 'llvm', 'google', 'webkit', 'mozilla'
                                  See clang-format documentation for the up-to-date
                                  information about formatting styles and options.
                                  This option overrides the 'FormatStyle` option in
                                  .clang-tidy file, if any.
  -header-filter=<string>       -
                                  Regular expression matching the names of the
                                  headers to output diagnostics from. Diagnostics
                                  from the main file of each translation unit are
                                  always displayed.
                                  Can be used together with -line-filter.
                                  This option overrides the 'HeaderFilter' option
                                  in .clang-tidy file, if any.
  -line-filter=<string>         -
                                  List of files with line ranges to filter the
                                  warnings. Can be used together with
                                  -header-filter. The format of the list is a
                                  JSON array of objects:
                                    [
                                      {"name":"file1.cpp","lines":[[1,3],[5,7]]},
                                      {"name":"file2.h"}
                                    ]
  -list-checks                  -
                                  List all enabled checks and exit. Use with
                                  -checks=* to list all available checks.
  -p=<string>                   - Build path
  -quiet                        -
                                  Run clang-tidy in quiet mode. This suppresses
                                  printing statistics about ignored warnings and
                                  warnings treated as errors if the respective
                                  options are specified.
  -store-check-profile=<prefix> -
                                  By default reports are printed in tabulated
                                  format to stderr. When this option is passed,
                                  these per-TU profiles are instead stored as JSON.
  -system-headers               - Display the errors from system headers.
  -vfsoverlay=<filename>        -
                                  Overlay the virtual filesystem described by file
                                  over the real file system.
  -warnings-as-errors=<string>  -
                                  Upgrades warnings to errors. Same format as
                                  '-checks'.
                                  This option's value is appended to the value of
                                  the 'WarningsAsErrors' option in .clang-tidy
                                  file, if any.
