changed-files

Effortlessly track all changed files and directories relative to a target branch, the current branch (preceding commit or the last remote commit), multiple branches, or custom commits returning relative paths from the project root using this GitHub action.

Note

This action solely identifies files that have changed for events such as pull_request*, push, merge_group, release, and many more. However, it doesn't detect pending uncommitted changes created during the workflow execution.

See: https://github.com/tj-actions/verify-changed-files instead

Features 🚀

Fast execution, averaging 0-10 seconds.
Leverages either Github's REST API or Git's native diff to determine changed files.
Facilitates easy debugging.
Scales to handle large/mono repositories.
Supports Git submodules.
Supports merge queues for pull requests.
Generates escaped JSON output for running matrix jobs based on changed files.
Lists changed directories.
- Limits matching changed directories to a specified maximum depth.
- Optionally excludes the current directory.
Writes outputs to a designated .txt or .json file for further processing.
Restores deleted files to their previous location or a newly specified location.
Supports fetching a fixed number of commits which improves performance.
Compatible with all platforms (Linux, MacOS, Windows).
Supports GitHub-hosted runners.
Supports GitHub Enterprise Server.
Supports self-hosted runners.
Lists all files and directories that have changed:
- Between the current pull request branch and the last commit on the target branch.
- Between the last commit and the current pushed change.
- Between the last remote branch commit and the current HEAD.
Restricts change detection to a subset of files and directories:
- Provides boolean output indicating changes in specific files.
- Uses Glob pattern matching.
  - Supports Globstar.
  - Supports brace expansion.
  - Supports negation.
- Uses YAML syntax for specifying patterns.
  - Supports YAML anchors & aliases.
  - Supports YAML multi-line strings.

And many more...

Usage 💻

Important

Push Events: When configuring actions/checkout, make sure to set fetch-depth to either 0 or 2, depending on your use case.
Mono Repositories: To avoid pulling the entire branch history, you can utilize the default actions/checkout's fetch-depth of 1 for pull_request events.
Quoting Multiline Inputs: Avoid using single or double quotes for multiline inputs. The value is already a string separated by a newline character. Refer to the Examples section for more information.
Credentials Persistence: If fetch-depth is not set to 0, make sure to set persist-credentials to true when configuring actions/checkout.
Matching Files and Folders: To match all files and folders under a directory, this requires a globstar pattern e.g. dir_name/** which matches any number of subdirectories and files.

When using files_yaml* inputs:
- All keys must start with a letter or _ and contain only alphanumeric characters, -, or _.
  
  For example, test or test_key or test-key or _test_key are all valid.

Important

When using files_yaml* inputs:
- it's required to prefix all outputs with the key to ensure that the correct outputs are accessible.
  
  For example, if you use test as the key, you can access outputs like added_files, any_changed, and so on by prefixing them with the key test_added_files or test_any_changed etc.

unmerged_files	string	Returns only files that are Unmerged (U).
unmerged_files_count	string	Returns the number of `unmerged_files`

Versioning 🏷️

This GitHub Action follows the principles of Semantic Versioning for versioning releases.

The format of the version string is as follows:

major: indicates significant changes or new features that may not be backward compatible.
minor: indicates minor changes or new features that are backward compatible.
patch: indicates bug fixes or other small changes that are backward compatible.

Important Notice ⚠️

Important

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 any hidden issues.

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.
