This application is a GitHub Action that analyzes Makefiles and returns the targets that depend on the input file.
- Retrieve targets as a list from dependent file names
- Find targets that depend on other targets
- Multiple targets
- Macros
- Suffixes rules
inputs:
makefile:
description: 'The Makefile to find build targets from'
default: 'Makefile'
required: false
dependencies:
description: 'Files to find with dependencies (separated by spaces)'
required: true
outputs:
targets:
description: "Returns targets"
value: ${{ steps.makefile-build-target-finder.outputs.targets }}Here's an example of how to write an action to retrieve the targets that depend on the file hello.c from the Makefile:
hello.o: hello.c
gcc -c hello.c
world.o: world.c
gcc -c world.c
helloWorld: hello.o world.o
gcc -o helloWorld hello.o world.o

- id: makefile-build-target-finder
uses: meihei3/makefile-build-target-finder@main
with:
makefile: 'tests/usage.mk'
dependencies: 'hello.c'
- id: check
needs: [ makefile-build-target-finder ]
shell: bash
run: echo ${{ steps.makefile-build-target-finder.outputs.targets }} # -> "helloWorld hello.o"By combining it with tj-actions/changed-files, you can also retrieve targets that depend on git changed files.
