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_FILTER

Keep only gcov data files that match this filter. Can be specified multiple times. Config key(s): gcovfilter.

--gcov-exclude GCOV_EXCLUDE

Exclude gcov data files that match this filter. Can be specified multiple times. Config key(s): gcov-exclude.

--gcov-exclude-directories GCOV_EXCLUDE_DIRS, --exclude-directories GCOV_EXCLUDE_DIRS

Exclude directories that match this regex while searching raw coverage files. Can be specified multiple times. Config key(s): gcov-excludedirectories, exclude-directories.

-f FILTER, --filter FILTER

Keep only source files that match this filter. Can be specified multiple times. Relative filters are relative to the current working directory or if defined in a configuration file. If no filters are provided, defaults to --root. Config key(s): filter.

-e EXCLUDE, --exclude EXCLUDE

Exclude source files that match this filter. Can be specified multiple times. Config key(s): exclude.

GCOV Options:

The 'gcov' tool turns raw coverage files (.gcda and .gcno) into .gcov files that are then processed by gcovr. The gcno files are generated by the compiler. The gcda files are generated when the instrumented program is executed.

-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-ignoreerrors.

--gcov-ignore-parse-errors [{all,negative_hits.warn,negative_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-ignoreparse-errors.

--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): gcovobject-directory, object-directory.

-k, --gcov-keep, --keep

Keep gcov files after processing. This applies both to files that were generated by gcovr, or were supplied via the --gcov-use-existing-files option. Config key(s): keep-gcov-files.

-d, --gcov-delete, --delete

Delete gcda files after processing. Config key(s): delete-gcov-files.

-j [GCOV_PARALLEL]

Set the number of threads to use in parallel. Config key(s): gcov-parallel.

--merge-mode-functions MERGE_MODE

The merge mode for functions coverage from different gcov files for same sourcefile.Default is 'strict'. Config key(s): merge-mode-functions.

--include-internal-functions

Include function coverage of compiler internal functions (starting with '__' or '_GLOBAL__sub_I_'). Config key(s): include-internal-functions.

--exclude-unreachable-branches

Exclude branch coverage from lines without useful source code (often, compiler-generated 'dead' code). Config key(s): exclude-unreachable-branches.

--exclude-function-lines

Exclude coverage from lines defining a function. Config key(s): exclude-function-lines.

--exclude-noncode-lines

Exclude coverage from lines which seem to be non-code. Negation: --no-exclude-noncode-lines. Config key(s): exclude-noncode-lines.

--exclude-throw-branches

For branch coverage, exclude branches that the compiler generates for exception handling. This often leads to more 'sensible' coverage reports. Config key(s): exclude-throw-branches.
