GitHub - JoeOvo/changed-files: :octocat: Github action to retrieve all (added, copied, modified, deleted, renamed, type changed, unmerged, unknown) files and directories.

changed-files

Retrieve all changed files and directories relative to the target branch (pull_request* based events) or the last remote commit (push based event) returning the absolute path to all changed files and directories from the project root.

Features

Fast execution (0-2 seconds on average).
Easy to debug.
Boolean output indicating that certain files have been changed.
Scales to large repositories.
Git submodules support.
No extra API calls.
Monorepos (Fetches only the last remote commit).
Supports all platforms (Linux, MacOS, Windows).
GitHub-hosted runners support
GitHub Enterprise Server support.
self-hosted runners support.
List all files and directories that have changed:
- Between the current pull request branch and the last commit on the target branch.
- Between the current pull request branch and the fork point on the target branch.
- Between the last commit and the current pushed change.
- Between the last remote branch commit and the current HEAD.
Restrict change detection to a subset of files and directories:
- Report on files that have at least one change.
- Using Glob pattern matching.

Usage

NOTE: ⚠️

IMPORTANT: For push events 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 you'll need to specify a token using the token input.

For monorepos where pulling all the branch history might not be desired, you can omit fetch-depth for pull_request events.

For files located in a sub-directory ensure that the pattern specified contains **/ (globstar) to match any preceding directories or explicitly pass the full path relative to the project root. See: #314.

Known Limitation

NOTE: ⚠️

Using characters like \n, %, . and \r as separators would be URL encoded

Spaces in file names can introduce bugs when using bash loops. See: #216 However, this action will handle spaces in file names, with a recommendation of using a separator to prevent hidden issues.

Versioning

This project follows a v(major).(patch) versioning scheme with the exception of pointing the git ref of the latest patch release to the major version tag.

NOTE: ⚠️

Users referencing the legacy v1.x.x -> v5.0.0 semantic versions, are required to switch over to v10.x -> v15.x respectively as new releases would no longer be deployed using the old versioning scheme.

A breaking change was introduced in v1.1.4 and v13.x which has been fixed.

Migration guide

With the switch from using grep's Extended regex to match files to the natively supported workflow glob pattern matching syntax introduced in v13 you'll need to modify patterns used to match files.
