Simple Github Action wrapper for Jake Wharton's Diffuse tool.
The action only exposes output containing the diff, so to effectively consume its output it is highly recommended to use other Github Actions to customize your experience.
By default, this action uses Diffuse fork - https://github.com/usefulness/diffuse (due to: JakeWharton/diffuse#111)
- id: diffuse
uses: usefulness/diffuse-action@v1
with:
old-file-path: old/file/path/old_file.apk
new-file-path: new/file/path/new_file.apk
You can override the config to use the original Diffuse binary
- id: diffuse
uses: usefulness/diffuse-action@v1
with:
old-file-path: old/file/path/old_file.apk
new-file-path: new/file/path/new_file.apk
diffuse-repo: JakeWharton/diffuse
lib-version: 0.1.0
old-file-path - Path to reference file the diff should be generated for
new-file-path - Path to current file the diff should be generated for
lib-version (Optional) - Overrides dependency version, by default uses the latest published version
diffuse-repo (Optional) - Overrides usefulness/diffuse as the default repository containing published release artifacts.
See full list of outputs.
For example: referencing steps.diffuse.outputs.diff-gh-comment at a later stage will print Diffuse tool output as a nicely formatted github comment
TODO: explain why to use free actions/cache for now and list its limitation.
