GitHub Action to match lines against a matcher

The following example workflow step will check for file: foo/bar against a matcher

- name: Match Lines
  uses: paypay/match-lines-action
  with:
    target_file: 'foo/bar'
    matcher: |
      app1:1\.[0-4]\.0
      app2:1\.0\.0
  ...

# This is a Gradle generated file for dependency locking.
# Manual edits can break the build and are not advised.
# This file is expected to be part of source control.
com.company1:app1:1.0.0=compileClasspath,runtimeClasspath
com.company1:app1:1.1.0=compileClasspath,runtimeClasspath
com.company1:app2:1.0.0=compileClasspath,runtimeClasspath
com.company2:app3:1.0.0=compileClasspath,runtimeClasspath
...

The following input variables options can/must be configured:

• match_count: Count of matched lines.

First, you'll need to have a reasonably modern version of node handy. This won't work with versions older than 9, for instance.

Install the dependencies

$ npm install

Build the typescript and package it for distribution

$ npm run build && npm run package

Run the tests ✔️

$ npm test

 PASS  ./index.test.js
  ✓ throws invalid number (3ms)
  ✓ wait 500 ms (504ms)
  ✓ test runs (95ms)

...

Actions are run from GitHub repos so we will checkin the packed dist folder.

Then run ncc and push the results:

$ npm run package
$ git add dist
$ git commit -a -m "prod dependencies"
$ git push origin releases/v1
