Colab Badge GitHub Action

Adds "Open in Colab" badges to Jupyter Notebooks and Markdown files. Updates badges for renamed or moved notebooks.

Usage

Badge Tag

• Use {{ badge }} tag to generate a badge for the notebook containing this tag (self-linking). Works only for Jupyter notebooks.

The following options work for both Jupyter and Markdown files (new in v4):

• Use {{ badge nb_path }} tag to generate a badge for a local notebook nb_path, and insert it to the file containing that tag (tag will be replaced with generated badge code). e.g. {{ badge dir1/dir2/nb.ipynb }}.
• Use {{ badge /nb_path }} tag to generate a badge for a remote (located in another repo) notebook /nb_path, and insert it to the file containing that tag. e.g. {{ badge /usr2/repo/blob/main/nb.ipynb }}. You can use full link (url) as well: {{ badge https://github.com/usr2/repo/blob/main/nb.ipynb }}.
• Use {{ badge //drive/nb_id }} tag to generate a badge for google drive notebook, and insert it to the file containing that tag. e.g. {{ badge //drive/abcde }}

Note: repo name and branch name are omitted for local notebooks, for notebooks from another repo only hostname can be ommited. In both cases file extension .ipynb can be omitted.

Action will create a badge for you:
