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.

The GitHub token used to authenticate API requests. You can use the {{ secrets.GITHUB_TOKEN }} token available in your workflow without any additional setup.

This is the key in which we mention the workflow name and pattern that we want to match which are seperated by ,.

This is required when you want to update on successfull run of a job.

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
      "sha":"some-sha", // string
      "diffFiles" : [ "file-1","file-2" ] // Array<string>
    }
}

It's a boolean which tell if these 2 commits have pattern matching file change.

It's a string which is the job key for which this is fetched appended with pr number.

It's a string which is the regex for file path match.

sha for last successful run.

Array of files that has been changed between current and last successfull sha.
