Sync labels on multiple repositories at once

[Slawomir Jaranowski]

In many case I want to sync labels on multiple repositories.
No I can set repository for action, but only one.

My proposition to support syntax like:

- uses: micnncim/action-label-syncer@v1
        with:
          repository: |
              myother/repository,
              myother/second-repository;
              myother/next-repository

we can split repositories name by new line, comma, semicolon

Could you try to use matrix? See also: #45

[Slawomir Jaranowski]

ok, matrix can be some workaround until we reach limits for github action:
https://docs.github.com/en/free-pro-team@latest/actions/reference/usage-limits-billing-and-administration#usage-limits
It also be cheaper when someone will use in private repo - one job consume less minute.

In my opinion support multiple repos by action will be more effective we will need one job for work.

So implementation it is not difficult - I can prepare next PR, but I need my previous PR.

Example configuration with matrix:

jobs:
  labels_sync:
    strategy:
      # don't break another job if one is failed
      fail-fast: false
      matrix:
        repo:
          - user/repo1
          - user/repo2
          - user/repo3

    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2.3.3

      - name: Sync
        uses: micnncim/action-label-syncer@v1.2.0
        with:
          repository: ${{ matrix.repo }}
          token: ${{ secrets.TOKEN }}
          prune: false

One of the reasons for wanting a multi-repo sync is if the repos all share a project board. This makes the shared project board more consistent with its use of standardized labels. As you probably know, the labels belong to the repo, not the project.

The matrix approach is compelling, other than the draw-back of kicking off a potentially large number of jobs.

The code does not appear to support multiple repos; just one repo. The fix would be pretty simple with some minor mods to main.go to accept a list of 1 or more repos.

If nobody else is working on that, I'd be happy to submit a pull-request.

Sorry for being late 🙇 I've added the support of multiple repositories and released v1.3.0. It's also available with v1.

[Jeroen de Bruijn]

Does anybody actually have this working? I have the following configuration but only repo-a is being processed.

- name: Synchronise GitHub labels
  uses: micnncim/action-label-syncer@3abd5ab72fda571e69fffd97bd4e0033dd5f495c # v1.3.0
  with:
    manifest: .github/labels.yml
    prune: false
    token: ${{ steps.generate_token.outputs.token }}
    repository: |
        me/repo-a
        me/repo-b

[Jeroen de Bruijn]

My bad, actually works but the token didn't have the appropriate permissions and I didn't see that because of #62. Multiple repositories from input now works as expected!
