commit_graph_dump is modified to use camelCase variables
in the output data.json. Saved the data for TensorBoard
in explorer/src/data.json, where it's useful for debugging
/ iterating on the frontend.
Summary:
This is a minimal script that will crawl the file-reachable commits in a
repository and dump statistics to a JSON file that can be further
analyzed interactively on a frontend.
Requires PyPI `gitpython` (and `matplotlib`, but this can be excised).
Requires `jupyter` to run.
(Mostly paired with @dandelionmane on 2018-02-08.)
