git-story

Animate the story of your Git project

git-story


Tell the story of your Git project by creating video animations (.mp4) of your commit history directly from your Git repo.

Use cases


  • Visualizing Git projects
  • Sharing desired parts of your workflow with your team
  • Creating animated Git videos for blog posts or YouTube
  • Helping newer developers learn Git

Features


  • Run a single command in the terminal to generate a custom Git animation (.mp4) from your repo
  • Specify any commit id or ref to start animating from (default: HEAD)
  • Specify the number of commits to include (default: 8)
  • Ref labels are drawn by default for HEAD, branch names, and tags
  • Simple branching structures (1 or 2 branches)
  • Add custom branded intro/outro sequences if desired
  • Dark mode and light mode

Requirements


Quickstart


1) Install manim and manim dependencies for your OS

2) Install GitPython:

$ pip3 install gitpython

3) Install git-story:

$ pip3 install git-story

4) Browse to the Git repository you want create an animation from:

$ cd path/to/project/root

5) Run the program:

$ git-story

6) A default animation .mp4 file will be created using the most recent 8 commits on your checked-out Git branch. By default, video output file is created in the current directory, within a subdirectory called git-story_media. The location this subdirectory is customizeable using the command line flag --media-dir=path/to/output.

7) Use command-line options for customization, see usage:

$ git-story -h

usage: git-story [-h] [--commits COMMITS] [--commit-id COMMIT_ID] [--hide-merged-chains] [--reverse] [--title TITLE] [--logo LOGO] [--outro-top-text OUTRO_TOP_TEXT]
                 [--outro-bottom-text OUTRO_BOTTOM_TEXT] [--no-intro] [--no-outro] [--max-branches-per-commit MAX_BRANCHES_PER_COMMIT] [--max-tags-per-commit MAX_TAGS_PER_COMMIT]

optional arguments:
  -h, --help            show this help message and exit
  --commits COMMITS     The number of commits to display in the Git animation (default: 8)
  --commit-id COMMIT_ID
                        The ref (branch/tag), or first 6 characters of the commit to animate backwards from (default: HEAD)
  --hide-merged-chains  Hide commits from merged branches, i.e. only display mainline commits (default: False)
  --reverse             Display commits in reverse order in the Git animation (default: False)
  --title TITLE         Custom title to display at the beginning of the animation (default: Git Story, by initialcommit.com)
  --logo LOGO           The path to a custom logo to use in the animation intro/outro (default: /usr/local/lib/python3.9/site-packages/git_story/logo.png)
  --outro-top-text OUTRO_TOP_TEXT
                        Custom text to display above the logo during the outro (default: Thanks for using Initial Commit!)
  --outro-bottom-text OUTRO_BOTTOM_TEXT
                        Custom text to display below the logo during the outro (default: Learn more at initialcommit.com)
  --show-intro          Add an intro sequence with custom logo and title (default: False)
  --show-outro          Add an outro sequence with custom logo and text (default: False)
  --max-branches-per-commit MAX_BRANCHES_PER_COMMIT
                        Maximum number of branch labels to display for each commit (default: 2)
  --max-tags-per-commit MAX_TAGS_PER_COMMIT
                        Maximum number of tags to display for each commit (default: 1)
  --media-dir MEDIA_DIR
                        The path to output the animation data and video file (default: .)
  --low-quality         Render output video in low quality, useful for faster testing (default: False)
  --light-mode          Enable light-mode with white background (default: False)

Command Examples


Default - draw 8 commits starting from HEAD, from oldest to newest:

$ cd path/to/project/root
$ git-story

Customize the start commit and number of commits, and reverse their display order:

$ cd path/to/project/root
$ git-story --commit-id a1b2c3 --commits=6 --reverse

Add an intro with custom title and logo:

$ cd path/to/project/root
$ git-story --commit-id dev --commits=10 --show-intro --title "My Git Repo" --logo ~path/to/logo.png

Add an outro with custom text and logo:

$ cd path/to/project/root
$ git-story --show-outro --outro-top-text "My Git Repo" --outro-bottom-text "Thanks for watching!" --logo path/to/logo.png

Customize the output video directory location:

$ cd path/to/project/root
$ git-story --media-dir=path/to/output

Use light mode for white background and black text, instead of the default black background with white text:

$ cd path/to/project/root
$ git-story --light-mode

Generate output video in low quality to speed up rendering time (useful for repeated testing):

$ cd path/to/project/root
$ git-story --low-quality

Installation


See QuickStart section for details on installing manim and GitPython dependencies. Then run:
