Gcovinator

gcovinator is a command-line tool that can generate HTML reports showing the line and branch coverage information for a source file. It is implemented as a Ruby gem and requires Ruby to be installed to execute.

Installation

With root access or something like rvm:

$ gem install gcovinator

Or as an unprivileged user without something like rvm:

$ gem install --user gcovinator

(in this case make sure the path to /bin under your ~/.gem directory is in your $PATH)

Usage

Usage: gcovinator [options] [FILES]

Pass paths to .gcda files as FILES.
If no FILES are specified, gcovinator looks for all .gcda files recursively under the build directory.

Options:
    -b, --build-dir BUILDDIR         Specify the build directory. Source file paths in object/gcov files will be relative to this directory. Defaults to '.' if not specified.
    -o, --output-dir OUTPUTDIR       Specify output directory. HTML reports will be written to this directory. Defaults to 'coverage' if not specified.
    -p, --prefix PREFIX              Prefix path to strip from source file paths. Defaults to '.' if not specified.
    -s, --source-dir SRCDIR          Specify a source directory. Reports will only be generated for sources under a specified source directory. Multiple source directories may be specified. Defaults to '.' if not specified.
    -h, --help                       Show this help.
        --version                    Show version

Example

If you store your source code under src and build from the build directory, then execute:

$ gcovinator -b build -s src
