                        color. Config key(s): force-color.
  -r ROOT, --root ROOT  The root directory of your source files. Defaults to '.', the current
                        directory. File names are reported relative to this root. The --root is
                        the default --filter. Config key(s): root.

  --exclude-function EXCLUDE_FUNCTION
                        Exclude coverage of functions. If function starts and end with '/' it is
                        treated as a regular expression. This option needs at least GCC 14 with a
                        supported version of JSON output format. ATTENTION: This option has no
                        effect when generating reports from JSON tracefile. Config key(s):

  --exclude-pattern-prefix EXCLUDE_PATTERN_PREFIX
                        Define the regex prefix used in markers / line exclusions (i.e
                        ..._EXCL_START, ..._EXCL_START, ..._EXCL_STOP). ATTENTION: This option has
                        no effect when generating reports from JSON tracefile except for the
                        syntax highlighting in the HTML report Config key(s): exclude-pattern-
                        prefix.

                        tracefile. Config key(s): warn-excluded-lines-with-hits.
  search_paths          Search paths for coverage files. Defaults to --root and --gcov-object-
                        directory. If path is a file it is used directly. Config key(s): search-
                        path.

Filter Options:
  Filters decide which files are included in the report. Any filter must match, and no exclude
  filter must match. A filter is a regular expression that matches a path. Filter paths use
  forward slashes, even on Windows. If the filter looks like an absolute path it is matched
  against an absolute path. Otherwise, the filter is matched against a relative path, where that
  path is relative to the current directory or if defined in a configuration file to the
  directory of the file.

  --gcov-filter GCOV_INCLUDE_FILTER

                        if defined in a configuration file. If no filters are provided, defaults
                        to --root. Config key(s): filter.
  -e EXCLUDE_FILTER, --exclude EXCLUDE_FILTER
                        Exclude source files that match this filter. Can be specified multiple

                        files. Can be specified multiple times. ATTENTION: This option has no
                        effect when generating reports from JSON tracefile. Config key(s):
                        exclude-directory, gcov-exclude-directory, gcov-exclude-directories,
                        exclude-directories.
  --trace-include TRACE_INCLUDE_FILTER
                        Log output for files that match this filter. The output is logged without
                        activating verbose mode. Can be specified multiple times. Config key(s):
                        trace-include.
  --trace-exclude TRACE_EXCLUDE_FILTER
                        Do not log very verbose output for files that match this filter. Can be
                        specified multiple times. Config key(s): trace-exclude.

  --sort {filename,uncovered-number,uncovered-percent}
                        Sort entries by filename, number or percent of uncovered lines or
                        branches(if the option --sort-branches is given). The default order is
                        increasing and can be changed by --sort-reverse. The secondary sort key
                        (if values are identical) is always the filename (ascending order). For
                        CSV, HTML, JSON, LCOV and text report. Config key(s): sort.

GCOV options:
  Options for reading GCOV text and JSON reports. JSON reports are the default for gcc-14 and
  newer (JSON format 2, see gcc --version).

  --gcov-allowed-working-directory-root GCOV_ALLOWED_WORKING_DIRECTORY_ROOTS
                        Do not run gcov in a working directory not in the list. The list contains
                        by default the search paths. ATTENTION: This option has no effect when
                        generating reports from JSON tracefile. Config key(s): gcov-allowed-
                        working-directory-root.
  -g, --gcov-use-existing-files, --use-gcov-files
                        Use existing gcov files for analysis. Config key(s): gcov-use-existing-
                        files, use-gcov-files.
  --gcov-ignore-errors [{all,source_not_found,output_error,no_working_dir_found}]
                        Ignore errors from invoking GCOV command instead of exiting with an error.
                        A report will be shown on stderr. Default is 'None'. Config key(s): gcov-
                        ignore-errors.
  --gcov-ignore-parse-errors [{all,negative_hits.warn,negative_hits.warn_once_per_file,suspicious_hits.warn,suspicious_hits.warn_once_per_file}]
                        Skip lines with parse errors in GCOV files instead of exiting with an
                        error. A report will be shown on stderr. Default is 'None'. Config key(s):
                        gcov-ignore-parse-errors.
  --gcov-suspicious-hits-threshold GCOV_SUSPICIOUS_HITS_THRESHOLD
                        Set the threshold for detecting suspicious hits in gcov output files. Set
                        to 0 to turn the detection off. Config key(s): gcov-suspicious-hits-
                        threshold.
  --gcov-executable GCOV_CMD
                        Use a particular gcov executable. Must match the compiler you are using,
                        e.g. 'llvm-cov gcov' for Clang. Can include additional arguments. Defaults
                        to the GCOV environment variable, or 'gcov': 'gcov'. Config key(s): gcov-
                        executable.
  --gcov-object-directory GCOV_OBJDIR, --object-directory GCOV_OBJDIR
                        Override normal working directory detection. Gcovr needs to identify the
                        path between gcda files and the directory where the compiler was
                        originally run. Normally, gcovr can guess correctly. This option specifies
                        either the path from gcc to the gcda file (i.e. gcc's '-o' option), or the
                        path from the gcda file to gcc's working directory. Config key(s): gcov-
                        object-directory, object-directory.
  -j [GCOV_PARALLEL]    Set the number of threads to use in parallel. 0=Number of CPUs, negative
                        number='all but N CPUs'. Config key(s): gcov-parallel.
  --merge-lines         Merge line coverage for same line coming from different functions, e.g.
                        template instances. The branches, conditions and calls are merged
                        accordingly. ATTENTION: This option doesn't affect the GCOVR JSON
                        intermediate format here still the raw data is reported. If you use a two
                        pass generation (1st run: GCOV -> JSON, 2nd run: JSON -> human readable
                        reports), the option is only needed in the second run. Config key(s):
                        merge-lines.
  --exclude-function-lines
                        Exclude coverage from lines defining a function.ATTENTION: This option has
                        no effect when generating reports from JSON tracefile. Config key(s):
                        exclude-function-lines.
