Retrieve all changed files and directories relative to the target branch (pull_request*
based events) or the last remote commit (push
or pull_request*
based event) returning the absolute path to all changed files and directories from the project root.
- 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.
- Escaped JSON Output which can be used for running matrix jobs based on changed files.
- List only changed directories.
- 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.
NOTE:
β οΈ
- IMPORTANT: For
push
events you need to includefetch-depth: 0
ORfetch-depth: 2
depending on your use case.- For monorepos where pulling all the branch history might not be desired, you can omit
fetch-depth
forpull_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.

β οΈ
- 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.
