gcovr --help (return code: 0)
Usage: gcovr [options] A utility to run gcov and generate a simple report that summarizes the coverage Options: -h, --help show this help message and exit --version Print the version number, then exit -v, --verbose Print progress messages --object-directory=OBJDIR Specify the directory that contains the gcov data files. gcovr must be able to identify the path between the *.gcda files and the directory where gcc was originally run. Normally, gcovr can guess correctly. This option overrides gcovr's normal path detection and can specify either the path from gcc to the gcda file (i.e. what was passed to gcc's '-o' option), or the path from the gcda file to gcc's original working directory. -o OUTPUT, --output=OUTPUT Print output to this filename -k, --keep Keep the temporary *.gcov files generated by gcov. By default, these are deleted. -d, --delete Delete the coverage files after they are processed. These are generated by the users's program, and by default gcovr does not remove these files. -f FILTER, --filter=FILTER Keep only the data files that match this regular expression -e EXCLUDE, --exclude=EXCLUDE Exclude data files that match this regular expression --gcov-filter=GCOV_FILTER Keep only gcov data files that match this regular expression --gcov-exclude=GCOV_EXCLUDE Exclude gcov data files that match this regular expression -r ROOT, --root=ROOT Defines the root directory for source files. This is also used to filter the files, and to standardize the output. -x, --xml Generate XML instead of the normal tabular output. --xml-pretty Generate pretty XML instead of the normal dense format. --html Generate HTML instead of the normal tabular output. --html-details Generate HTML output for source file coverage. --html-absolute-paths Set the paths in the HTML report to be absolute instead of relative -b, --branches Tabulate the branch coverage instead of the line coverage. -u, --sort-uncovered Sort entries by increasing number of uncovered lines. -p, --sort-percentage Sort entries by decreasing percentage of covered lines. --gcov-executable=GCOV_CMD Defines the name/path to the gcov executable [defaults to the GCOV environment variable, if present; else 'gcov']. --exclude-unreachable-branches Exclude from coverage branches which are marked to be excluded by LCOV/GCOV markers or are determined to be from lines containing only compiler-generated "dead" code. -g, --use-gcov-files Use preprocessed gcov files for analysis. -s, --print-summary Prints a small report to stdout with line & branch percentage coverage
