## GitHub Actions for Hugo

- [gohugoio/hugo: The world’s fastest framework for building websites.](https://github.com/gohugoio/hugo)

This **Hugo Setup Action** can install **Hugo** to a virtual machine of **GitHub Actions**.
**Hugo extended** version, **Hugo Modules**, Linux (Ubuntu), macOS, and Windows are supported.

From `v2`, this Hugo Setup Action has migrated to a JavaScript (TypeScript) action.
We no longer build or pull a Hugo docker image.
Thanks to this change, we can complete this action in less than a few seconds.
(A docker base action was taking about 1 min or more execution time to build and pull a docker image.)

| OS (runs-on) | ubuntu-18.04 | macos-latest | windows-2019 |

## Getting started

### ⭐️ Create your workflow

An example workflow `.github/workflows/gh-pages.yml` with [GitHub Actions for GitHub Pages].
For the first deployment, we have to do this operation: [First Deployment with `GITHUB_TOKEN` - peaceiris/actions-gh-pages](https://github.com/peaceiris/actions-gh-pages#%EF%B8%8F-first-deployment-with-github_token)

[GitHub Actions for GitHub Pages]: https://github.com/peaceiris/actions-gh-pages

[![peaceiris/actions-gh-pages - GitHub](https://gh-card.dev/repos/peaceiris/actions-gh-pages.svg?fullname)](https://github.com/peaceiris/actions-gh-pages)

```yaml
name: github pages

on:
  push:
    branches:
      - main

jobs:
  deploy:
    runs-on: ubuntu-18.04
    steps:
      - uses: actions/checkout@v2
        with:
          submodules: true  # Fetch Hugo themes (true OR recursive)
          fetch-depth: 0    # Fetch all history for .GitInfo and .Lastmod

      - name: Setup Hugo
        uses: peaceiris/actions-hugo@v2
        with:
          hugo-version: '0.74.1'
          # extended: true

      - name: Build
        run: hugo --minify

      - name: Deploy
        uses: peaceiris/actions-gh-pages@v3
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          publish_dir: ./public
```

## Options

### ⭐️ Use Hugo extended

Set `extended: true` to use a Hugo extended version.

```yaml
- name: Setup Hugo
  uses: peaceiris/actions-hugo@v2
  with:
    hugo-version: '0.74.1'
    extended: true
```

### ⭐️ Use the latest version of Hugo

Set `hugo-version: 'latest'` to use the latest version of Hugo.

```yaml
- name: Setup Hugo
  uses: peaceiris/actions-hugo@v2
  with:
    hugo-version: 'latest'
```

This action fetches the latest version of Hugo by [hugo | Homebrew Formulae](https://formulae.brew.sh/formula/hugo)

## Tips

### ⭐️ Read Hugo version from file

How to sync a Hugo version between a Docker Compose and a GitHub Actions workflow via `.env` file.

Write a `HUGO_VERSION` to the `.env` file like the following and push it to a remote branch.

```sh
HUGO_VERSION=0.74.1
```

Next, add a step to read a Hugo version from the `.env` file.

```yaml
    - name: Read .env
      id: hugo-version
      run: |
        . ./.env
        echo "::set-output name=HUGO_VERSION::${HUGO_VERSION}"        

    - name: Setup Hugo
      uses: peaceiris/actions-hugo@v2
      with:
        hugo-version: '${{ steps.hugo-version.outputs.HUGO_VERSION }}'
        extended: true
```

Here is a `docker-compose.yml` example.

```yaml
version: '3'

services:
  hugo:
    container_name: hugo
    image: "peaceiris/hugo:v${HUGO_VERSION}"
    # image: peaceiris/hugo:v${HUGO_VERSION}-mod  # Hugo Modules
    ports:
      - 1313:1313
    volumes:
      - ${PWD}:/src
    command:
      - server
      - --bind=0.0.0.0
      - --buildDrafts
```

The alpine base Hugo Docker image is provided on the following repository.

> [peaceiris/hugo-extended-docker: Hugo alpine base Docker image (Hugo extended and Hugo Modules)](https://github.com/peaceiris/hugo-extended-docker)

### ⭐️ Workflow for autoprefixer and postcss-cli

Here is an example workflow for the [google/docsy] Hugo theme.
This theme needs `autoprefixer` and `postcss-cli` to build a project.
The following workflow is tested on [google/docsy-example].

[google/docsy]: https://github.com/google/docsy
[google/docsy-example]: https://github.com/google/docsy-example

A workflow for the Hugo Babel pipeline is also the same as follows.

```yaml
name: github pages

on:
  push:
    branches:
      - main

jobs:
  deploy:
    runs-on: ubuntu-18.04
    steps:
      - uses: actions/checkout@v2
        with:
          submodules: recursive  # Fetch the Docsy theme
          fetch-depth: 0         # Fetch all history for .GitInfo and .Lastmod

      - name: Setup Hugo
        uses: peaceiris/actions-hugo@v2
        with:
          hugo-version: '0.74.1'
          extended: true

      - name: Setup Node
        uses: actions/setup-node@v1
        with:
          node-version: '12.x'

      - name: Cache dependencies
        uses: actions/cache@v1
        with:
          path: ~/.npm
          key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
          restore-keys: |
            ${{ runner.os }}-node-            

      - run: npm ci
      - run: hugo --minify

      - name: Deploy
        uses: peaceiris/actions-gh-pages@v3
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
```

### ⭐️ Workflow for asciidoctor

Here is an example workflow for a Hugo project using `asciidoctor`.

```yaml
name: github pages

on:
  push:
    branches:
      - main

jobs:
  deploy:
    runs-on: ubuntu-18.04
    steps:
      - uses: actions/checkout@v2
        with:
          submodules: true  # Fetch Hugo themes (true OR recursive)
          fetch-depth: 0    # Fetch all history for .GitInfo and .Lastmod

      - name: Setup Hugo
        uses: peaceiris/actions-hugo@v2
        with:
          hugo-version: '0.74.1'
          extended: true

      - name: Setup Ruby
        uses: ruby/setup-ruby@v1
        with:
          ruby-version: 2.7

      - run: gem install asciidoctor

      - name: Run Hugo
        run: |
          alias asciidoctor="asciidoctor --attribute=experimental=true --attribute=icons=font"
          hugo --minify          

      - name: Deploy
        uses: peaceiris/actions-gh-pages@v3
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
```
