Visualize git repositories as they change, live in the browser.
gitviz might be useful as a teaching tool for git.
It draws graphviz graphs on <canvas> elements, and updates them as you modify the target git repository on the fly.
You need Python, Node.js, npm, and a git repository.
# get code git clone git://github.com/kevinw/gitviz.git # start the webserver cd gitviz ./run-server PATH_TO_REPOS # where PATH_TO_REPOS is the path above your repositories # see live graphs in the browser open http://localhost:3000/reponame
gitviz is just glue around lots of great libraries:
- dulwich reads your git repositories as graphs
- pydot emits those graphs as DOT language
- canviz draws DOT language as visual graphs in <canvas> tags in the browser
- express serves the webpage showing the graph
- socket.io notifies the browser in realtime when the graph changes
- The node library "watch" we're using uses polling under the hood. There are definitely better alternatives that hook into filesystem events.
- Animate the graph when it changes.
- Show working copy modifications. Maybe an asterisk next to the blobs that differ?
- Eliminate bottlenecks for non-toy-sized repositories, and make them navigable/intelligible in some way.
- Make the graph interactive, or somehow have each node show the git command that made it.
