2018-12-19utils: checkstyle.py: Strip trailing white spacesLaurent Pinchart
As astyle doesn't strip trailing white spaces, strip them manually. Organize the code to allow for new additional formatting steps if needed. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2018-12-19utils: checkstyle.py: Highlight trailing white space at end of lineLaurent Pinchart
In order to facilitate interpretation of diffs, highlight trailing white space at end of lines with a red background. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2018-12-19utils: checkstyle.py: Support execution from non-root directoriesLaurent Pinchart
The git diff command is invoked with relative paths, which causes git to fail to locate files when the checkstyle.py script is run from subdirectories of the git tree. Fix this by prepending the absolute path to the git tree root directory to the file names. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2018-12-14utils: Add Python-based commit style checker scriptLaurent Pinchart
checkstyle.py is a reimplementation of checkstyle.sh in Python, that should be easier to extend with additional features. Three additional features and enhancements are already implemented: - While retaining the default behaviour of operating on the HEAD commit, a list of commits can also be specified on the command line. - Correct line numbers are printed in the diff output. - The index and working tree are not touched, they can be dirty.
