Issue: support for reusable workflows

[catthehacker]

ref: github/roadmap#98

GitHub is going to support reusable workflows (similar to Azure DevOps Pipelines)

How will it work?
To reuse a workflow, ensure it listens to a new workflow_call event trigger, and then reference it with the familiar uses syntax. Optionally, use inputs and outputs to pass data between them, just like with actions.

For example:

name: Build & Release App

on:
  push:

jobs:
  build:
    uses: example-org/automation/workflows/build.yml@1

  release:
    needs: build
    uses: example-org/automation/workflows/release.yml@1
    with:
      artifact-url: jobs.build.outputs.artifact-url

I want to add someone found the beta documentation ( source )
https://docs.github.com/en/actions/learn-github-actions/reusing-workflows

I'm going to implement it in my own actions-service (runner.server)

It seems to be even deployed as beta. Far more information than in the roadmap.

EDIT 2021/10/28:
For reusable workflows it might be useful to backport the following commit ChristopherHX@efdc2fa after my PR uses in composite is merged

EDIT 2022/03/28
The commit mentioned in the previous edit has been merged via the uses in composite and is already in v0.2.26.
This issue has a low priority for me.
DONE:

• make inputs context available in the runcontext

TODO:

• obtain the reusable workflows in the planner
• evaluate the inputs and secrets
• only make evaluated secrets available in the reusable workflow
• assign the evaluated inputs to the runcontext of the reusable workflow
• evaluate workflow outputs and add the jobs context, the same as needs of a job which depends on all other jobs in the reusable workflow

We just started implementing reusable workflows. As I was going through the pains of several commits and merges leading to broken workflows I came across this repo! It was linked in the recent Thoughtworks Technology Radar. Anyways just here to say I'm looking forward to using it !!

That's because they are not supported

Hi, just wondering if support for reusable workflows is on the backlog for act?

Yes, that's why this issue is opened

--- EDIT ---

Issue is locked because none of recent responses are helpful at all. Please familiarise yourself with https://github.com/golang/go/wiki/NoPlusOne/
In case of this, we are aware of the reusable workflows (I raised the issue after all). If there will be any news regarding this issue, it will be updated and/or unlocked.
If there will be an attempt at implementing it, its pull request will be linked. (Please feel free to contribute it)
Please do not ask when is this going to be implemented. It's annoying and doesn't contribute at all.
