Tool to visualize source code history
Based on this idea: https://github.com/drummyfish/gitviz
- Performance improvements
- Fix large diffs on merge commits
- Visualize multiple files at once
- Add a way to include and exclude files based on file name globs (e.g. *.py)
- Customize ffmpeg command options
- Add live-preview with ffplay
- Customize the commit message string
- Add various verbosity flags (e.g. to show ffmpeg output)
- Add a speedup factor (render a frame every N changes only)
- Add a scaling factor (render images bigger than final video)
GitVid is written for Python3 and uses pygments for syntax highlighting and PIL or Pillow for image rendering. It calls git to fetch the history and ffmpeg to render the video. These commands must be installed and present in the current $PATH.
Debian/Ubuntu:
$ sudo apt-get install python3-imaging python3-pygments ffmpeg git
Max OSX:
$ brew install ffmpeg
$ brew install git
$ pip install pygments Pillow
usage: gitvid.py [-h] [-o OUT] [--fps FPS] [--size SIZE] [--style STYLE]
[--fast] [--dry-run]
SOURCE PATH
Visualize source code history
positional arguments:
SOURCE Source folder (git repository)
PATH Filenames to include in the visualization
optional arguments:
-h, --help show this help message and exit
-o OUT, --out OUT Filename fo the target video file. (default: gitvid.flv)
--fps FPS Frames per second (default: 60)
--size SIZE Video resolution. Either [WIDTH]x[HEIGHT] or the name of
a common resolution (e.g. 790p, 1080p, 4k, ...) (default:
790p)
--style STYLE Pygments syntax highlighting style (default: No syntax
highlighting)
--fast Do not visualize individual line additions and deletions,
but only full commits.
