This GitHub Action extracts the sha of the last successful run of a specified job, compares it with the latest commit, finds the changed files, and performs a pattern match provided by the user. If the pattern matches any changed files, it returns true otherwise, it returns false.

This GitHub Action relies on the following dependencies:

• @actions/core: The @actions/core package provides functions for setting and getting input and output variables used in GitHub Actions.
• @actions/github: The @actions/github package provides functions for interacting with the GitHub API in GitHub Actions.
• octokit: The octokit package is used for making API requests to the GitHub API.
• picomatch: The picomatch package is used for pattern matching using regular expressions.
• @actions/artifacts: The @actions/artifacts package is used for uploading and downloading artifacts.
• adm-zip: The adm-zip package is used for unzipping the zip files.

Ensure that you have these dependencies installed or included in your workflow environment before using this action.

This Return a status object in which the following are present

{
  "job_1": {
    "shouldRun": true, // boolean
    "key": "job_1-{pr-number}", // string
    "suppliedKey": "job_1", // string
    "filesRegex": "regex", // string
