Provide optional toString encoding for building strings with result

[themightychris]

I'm trying to build a branch name using a part of context.ref via this script, but the JSON encoding is getting in the way:

name: Push docs

on:
  push:
    branch:
      - releases/**

jobs:
  load:
    runs-on: ubuntu-latest
    steps:
    - id: get-release-name
      name: Get release name with github-script
      uses: actions/github-script@0.2.0
      with:
        github-token: ${{github.token}}
        script: return context.ref.replace(/^refs\/heads\/releases\//, '')
    - name: Push docs
      env:
        DOCS_BRANCH: docs/${{steps.get-release-name.outputs.result}}
      run: |
        printenv | grep DOCS_BRANCH

The output is:

DOCS_BRANCH=docs/"v1"

This can be still usable if you're dropping the value into a shell context that will eat the quotes, but is problematic if you're using it to build parameterized inputs for an action. If you made it so you could optionally set result-encoding: string to override the json default and just cast the result to a string:

    steps:
    - id: get-branch-name
      name: Get branch name with github-script
      uses: actions/github-script@0.2.0
      with:
        github-token: ${{github.token}}
        result-encoding: string
        script: return context.ref.replace(/^refs\/heads\/releases\//, '')
    - name: Push docs
      uses: myorg/push-docs@v1
      with:
        commit-to: docs/${{steps.get-release-name.outputs.result}}

Then the outputs.result of the step would be usable in building strings later in the job

Having a similar issue myself right now; I'm wondering if you figured out a good workaround for this?

I ended up just building my own JavaScript action to do my whole workflow
