GitHub Actions

Automatic translations in your pull requests. Every PR gets translated, committed, and ready to merge.

Quick Start

Add this workflow to your repository. That's it.

Example workflow · .github/workflows/localhero.yml

name: Translate

on:
  pull_request:
    paths:
      - "locales/**"  # Adjust to your path
      - "localhero.json"
  workflow_dispatch:

jobs:
  translate:
    runs-on: ubuntu-latest
    permissions:
      contents: write
      pull-requests: write
    steps:
      # Checkout PR with history so we only translate what changed
      - uses: actions/checkout@v4
        with:
          ref: ${{ github.head_ref }}
          fetch-depth: 0

      - uses: localheroai/action@v1
        with:
          api-key: ${{ secrets.LOCALHERO_API_KEY }}

Setup checklist

1. Create the workflow file above at .github/workflows/localhero.yml

2. Add your API key to repository secrets as LOCALHERO_API_KEY

Repository → Settings → Secrets and variables → Actions → New secret

3. Update the paths: to match where your translation files live

Get your API key from your account.

How it works

When it runs

The workflow triggers when a PR changes your translation files. It compares your branch to the base branch, finds new or modified keys, translates them, and commits the results directly to your PR.

What gets skipped

The action automatically skips translation when:

• PR has a skip-translation label
• PR is a draft
• Commit was made by the LocalHero bot (prevents loops)

Permissions

contents: write lets the action commit translations. pull-requests: write allows adding PR comments.

Configuration

The action accepts these inputs:

Input	Default	Description
`api-key`	required	Your LocalHero API key
`command`	`ci`	CLI command: `ci`, `translate`, `push`, `pull`
`verbose`	`false`	Show detailed output
`cli-version`	`latest`	Pin to a specific CLI version
`skip-labels`	`skip-translation`	PR labels that skip translation (comma-separated)

Example with options

- uses: localheroai/action@v1
  with:
    api-key: ${{ secrets.LOCALHERO_API_KEY }}
    verbose: true
    skip-labels: 'skip-translation,wip,no-i18n'

Common patterns

Gettext / PO files

For projects using gettext, run your message extraction before the action:

Example with Python/Django

steps:
  - uses: actions/checkout@v4
    with:
      ref: ${{ github.head_ref }}
      fetch-depth: 0

  - uses: actions/setup-python@v5
    with:
      python-version: '3.11'

  - name: Extract messages
    run: |
      pip install -r requirements.txt
      python manage.py makemessages -a

  - uses: localheroai/action@v1
    with:
      api-key: ${{ secrets.LOCALHERO_API_KEY }}

Adjust the extraction command for your framework: xgettext for C/C++, pybabel extract for Flask, etc.

Manual trigger

The workflow includes workflow_dispatch, so you can run it manually from the Actions tab.

Alternative: Using the CLI directly

For advanced use cases, you can call the CLI directly instead of using the action. This gives you full control but requires more setup.

name: Translate

on:
  pull_request:
    paths:
      - "config/locales/**"
  workflow_dispatch:

concurrency:
  group: translate-${{ github.head_ref || github.run_id }}
  cancel-in-progress: true

jobs:
  translate:
    if: |
      !contains(github.event.pull_request.labels.*.name, 'skip-translation') &&
      github.event.pull_request.draft == false &&
      !(github.actor == 'localhero-ai[bot]' && github.event.action == 'synchronize')
    runs-on: ubuntu-latest
    permissions:
      contents: write
      pull-requests: write

    steps:
    - uses: actions/checkout@v4
      with:
        ref: ${{ github.head_ref }}
        fetch-depth: 0

    - name: Fetch base branch
      if: github.event_name == 'pull_request'
      run: git fetch --no-tags origin ${{ github.base_ref }}

    - uses: actions/setup-node@v4
      with:
        node-version: 22

    - name: Translate
      env:
        LOCALHERO_API_KEY: ${{ secrets.LOCALHERO_API_KEY }}
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        GITHUB_BASE_REF: ${{ github.base_ref }}
      run: npx -y @localheroai/cli ci

The init command can generate this file for you: npx @localheroai/cli init
