Multiple Output Formats

You can write multiple report formats with one gcovr invocation by passing the output filename directly to the report format flag. If no filename is specified for the format, the value from -o/--output is used by default, which itself defaults to stdout.

The following report format flags can take an optional output file name:

• gcovr --csv
• gcovr --txt
• gcovr --cobertura
• gcovr --html
• gcovr --html-details
• gcovr --html-nested
• gcovr --sonarqube
• gcovr --json
• gcovr --json-summary
• gcovr --coveralls

If the value given to the output option ends with a path seperator (/ or \) it is used a directory which is created first and a default filename depending on the format is used.

Note that --html-details and --html-nested override any value of --html if it is present.
