GitHub Action: Template Repository Sync

Keep projects in sync with the template repository they came from

release semantic

Why?

The Template Repository feature is a great way to accelerate creation of new projects.

However, after you "use" the template for first time, the two repositories will forever be out of sync (any changes made to the template repository will not be reflected in the project repository)

Usage

This action will automatically detect all repositories within your account (user or org) that has been "initialized" from the template repository (referred to as "dependents" in this doc)

Note

There is currently a bug in the GitHub APIs preventing this action from automatically detecting dependent repositories, until this is tis resolved, please use additional property in the config file to manually include repositories you want to sync

Important

MUST USE Fine-grained Personal Access Token, for whatever reason, Classic tokens stopped working with the "contents" scope, which is required for this action to work

.github/workflows/template-sync.yml
on: [push, pull_request]

jobs:
  template-sync:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2 # important!
      - uses: khulnasoft/action-template-sync@v2
        with:
          github-token: ${{ secrets.GH_TOKEN }}
          dry-run: true
A more practical example 
name: template-sync

on:
  pull_request: # run on pull requests to preview changes before applying

  workflow_run: # setup this workflow as a dependency of others
    workflows: [test, release] # don't sync template unless tests and other important workflows have passed

jobs:
  template-sync:
    timeout-minutes: 20

    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2
      - uses: khulnasoft-lab/action-workflow-run-wait@v1 # wait for workflow_run to be successful
      - uses: khulnasoft-lab/action-workflow-queue@v1 # avoid conflicts, by running this template one at a time
      - uses: khulnasoft/action-template-sync@v1
        with:
          github-token: ${{ secrets.GH_TOKEN }}

Warning

HIGHLY RECOMMEND to set dry-run: true for the first time you use this action, inspect the output to confirm if the affected repositories list is what you wanted to commit files to

.github/template-sync.yml
dependents:
  - "api-*" # include
  - "!lib-*" # exclude

additional:
  - "another-one-*" # include
  - "!not-this-*" # exclude

files:
  - ".gitignore" # include
  - "!package.json" # exclude
  - "!(package-lock.json|yarn.lock)"

  # you probably want to exclude these files:
  - "!.github/workflows/template-sync.yml"
  - "!.github/template-sync.yml"

  # remap file names at destination repo
  - .gitignore-example: .gitignore

Config File

dependents

a list of repository name patterns

when not present or empty, the action will update EVERY DEPENDENT repository

additional

a list of repository name patterns

expands the list of repos in addition to the detected dependant repos, use this to sync repos that were not originally initialized from the template repository.

files

a list of filename patterns to include or exclude

NOTE: You can set a different destination for synced files using the object syntax: source_path: destination_path

Example
files:
  # remap file names at destination repo
  - templates/.gitignore-example: .gitignore

Pattern syntax

Warning

Always use forward-slashes in glob expressions and backslashes for escaping characters.

Tip

This package uses a micromatch as a library for pattern matching.

Inputs

input required default description
github-token ✔️ - The GitHub token used to call the GitHub API
config ❌ .github/template-sync.yml path to config file
dry-run ❌ false toggle info mode (commits wont occur)

⚠️ Operational Logic

  • The action will only run on the following event types: schedule,workflow_dispatch,repository_dispatch,pull_request,release,workflow_run,push.
  • The when run in pull_request, the action will post post a comment on the the Pull Request with the diff view of files to be changed.
  • The action will look for files under the GITHUB_WORKSPACE environment path
  • The action will read file contents AT RUNTIME (so you can run build steps or modify content before running the action if you so wish)
  • If no config file is present indicating which files to filter, the action will sync ALL FILES in the template repository
  • The action will respect .gitignore files
  • Files on target repos WILL BE CREATED if they do not exist
