📖 GitHub Action to publish files to a GitHub wiki

# Uploaded to wiki tab 👉 wiki/ ├── AsciiDoc-with-links.asciidoc ├── AsciiDoc.asciidoc ├── Home.md ├── Lots-of-content.md ├── Lots-of-links.md ├── Page-that-is-not-visible.adoc ├── Page-with-dashes.md ├── Page-with-image.md ├── Page_with_underscores.md ├── Plain-text.txt └── tiger.png

⬆️ Uploads a bunch of files to a repository's wiki
📚 Works great for documentation
🔀 Allows contributors to open Pull Requests for wiki content
🤝 Works well with actions4gh/configure-wiki to fix links

Usage

🚀 Here's what you're after:

# .github/workflows/deploy-wiki.yml
name: deploy-wiki
on:
  push:
    branches: "main"
    paths: wiki/**
jobs:
  deploy-wiki:
    permissions:
      contents: write
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions4gh/configure-wiki@v1
      - uses: actions4gh/deploy-wiki@v1

👆 This GitHub workflow will deploy the wiki content from wiki/ (can be changed with the path input) to the GitHub wiki tab for the current repository.

Inputs

• github-server-url: The base URL for the GitHub instance that you are trying to clone from, will use environment defaults to fetch from the same instance that the workflow is running from unless specified. Example URLs are https://github.com or https://my-ghes-server.example.com. The default is github.server_url. It's unlikely you need to change this unless you are deploying across a GHES boundary.

• repository: The repository slug to use as the base project target of the wiki. The contents will be deployed to this repository's wiki tab, not the repository itself. Use this if you are pushing contents across the repository boundary. Defaults to the current repository from github.repository.

• token: Set this if you are pushing to a different repository. This token will need write permissions. The default is github.token.

• path: Path of the directory containing the wiki files to be deployed. Defaults to the wiki/ folder.

Outputs

• wiki-url: The URL of the published GitHub wiki homepage. Usually something like https://github.com/octocat/project/wiki.

Bidirectional wiki sync

Sometimes you want two-way wiki sync so that edits from the repository are reflected in the wiki and edits from the wiki are committed to the repository. You've seen above how to go from the source repository to the wiki tab. Here's a complete demo using actions/checkout to download the wiki Gollum repository, perform the un-wiki-ification of the links, and commit it to the source repository.

# .github/workflows/sync-wiki.yml
name: Sync wiki
on:
  push:
    branches: "main"
    paths: wiki/**
  gollum:
  schedule:
    - cron: "8 14 * * *"
jobs:
  deploy-wiki:
    if: github.event_name == 'push'
    permissions:
      contents: write
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions4gh/configure-wiki@v1
      - uses: actions4gh/deploy-wiki@v1
  commit-wiki:
    if: github.event_name != 'push'
    permissions:
      contents: write
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/checkout@v4
        with:
          repository: ${{ github.repository }}.wiki
          path: wiki
      - run: rm -rf wiki/.git
      - uses: actions4gh/configure-wiki/reverse@v1
      - uses: actions4git/add-commit-push@v1

Pushing to another repository's wiki

If you want to push the contents of octocat/wiki to octocat/project, then you'll first need a GitHub Personal Access Token with permission to write the contents of the destination repository. In this example, that's octocat/project. Then you can use this action like this:

- uses: actions4gh/deploy-wiki@v1
  with:
    repository: octocat/project
    token: ${{ secrets.MY_TOKEN }}
