"The SNK body length could be increased from 5 to 7 and its getting larger after a few adjustments to the SNK SVGs mentioned above. The source code for generating the SNK SVGs still includes some shortcuts and isn't quite stable, as it fails to generate the SVGs consistently with the same SNK size and contribution charts with larger commits. This means that the larger the commits are, the more complex the SNK moving path becomes."

==========================================

Generates a snake game from a github user contributions graph

Pull a github user's contribution graph. Make it a snake Game, generate a snake path where the cells get eaten in an orderly fashion.

Generate a gif or svg image.

Available as github action. It can automatically generate a new image each day. Which makes for great github profile readme

github action

- uses: Platane/snk@v3
  with:
    # github user name to read the contribution graph from (**required**)
    # using action context var `github.repository_owner` or specified user
    github_user_name: ${{ github.repository_owner }}

    # list of files to generate.
    # one file per line. Each output can be customized with options as query string.
    #
    #  supported options:
    #  - palette:     A preset of color, one of [github, github-dark, github-light]
    #  - color_snake: Color of the snake
    #  - color_dots:  Coma separated list of dots color.
    #                 The first one is 0 contribution, then it goes from the low contribution to the highest.
    #                 Exactly 5 colors are expected.
    outputs: |
      dist/github-snake.svg
      dist/github-snake-dark.svg?palette=github-dark
      dist/ocean.gif?color_snake=orange&color_dots=#bfd6f6,#8dbdff,#64a1f4,#4b91f1,#3c7dd9

example with cron job

If you are only interested in generating a svg, consider using this faster action: uses: Platane/snk/svg-only@v3

dark mode

For dark mode support on github, use this special syntax in your readme.

<picture>
  <source media="(prefers-color-scheme: dark)" srcset="github-snake-dark.svg" />
  <source media="(prefers-color-scheme: light)" srcset="github-snake.svg" />
  <img alt="github-snake" src="github-snake.svg" />
</picture>
