A GitHub Action that creates a new issue using a template file.

This GitHub Action creates a new issue based on an issue template file. Here's an example workflow that creates a new issue any time you push a commit:

# .github/workflows/issue-on-push.yml
on: [push]
name: Create an issue on push
jobs:
  stuff:
    steps:
      - uses: JasonEtco/create-an-issue@v2
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

This reads from the .github/ISSUE_TEMPLATE.md file. This file should have front matter to help construct the new issue:

---
title: Someone just pushed
assignees: JasonEtco, matchai
labels: bug, enhancement
---
Someone just pushed, oh no! Here's who did it: {{ payload.sender.login }}

You'll notice that the above example has some {{ mustache }} variables. Your issue templates have access to everything about the event that triggered the action. Here is a list of all of the available template variables.

Note that you can only assign people matching given conditions.

Additionally, you can use the date filter and variable to show some information about when this issue was created:

---
title: Weekly Radar {{ date | date('dddd, MMMM Do') }}
---
What's everyone up to this week?

This example will create a new issue with a title like Weekly Radar Saturday, November 10th. You can pass any valid Moment.js formatting string to the filter.

Don't want to use .github/ISSUE_TEMPLATE.md? You can pass an input pointing the action to a different template:

steps:
  - uses: actions/checkout@v2
  - uses: JasonEtco/create-an-issue@v2
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
    with:
      filename: .github/some-other-template.md

Want to use Action logic to determine who to assign the issue to? You can pass an input containing the following options:

steps:
  - uses: actions/checkout@v2
  - uses: JasonEtco/create-an-issue@v2
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
    with:
      assignees: JasonEtco, octocat
      milestone: 1

If you need the number or URL of the issue that was created for another Action, you can use the number or url outputs, respectively. For example:

steps:
  - uses: JasonEtco/create-an-issue@v2
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
    id: create-issue
  - run: 'echo Created issue number ${{ steps.create-issue.outputs.number }}'
  - run: 'echo Created ${{ steps.create-issue.outputs.url }}'
