changed-files
-------------
Get all modified files relative to the default branch (`pull_request*` events) or last commit (`push` event).
## Features
- List all files that have changed
- Between the current pull request branch and the default branch
- Between the last commit and the current pushed change.
- Restrict change detection to a subset of files.
- Report on files that have all changed.
- Report on files that have at least one file change.
- Regex pattern matching on a subset of files.
## Usage
> NOTE: :warning:
> * For `push` events to work you need to include `fetch-depth: 0` **OR** `fetch-depth: 2` depending on your use case.
> * When using `persist-credentials: false` with `actions/checkout@v2` action
> you need to specify a `token` using the `token` input.
