Makefile Target Generator — Scaffold, Validate, and Self-Document Makefiles
Define make target names and commands and dependencies to generate a formatted Makefile with PHONY targets
How to Use Makefile Target Generator — Scaffold, Validate, and Self-Document Makefiles
How to Use the Makefile Target Generator
Step 1: Define a Target
Enter a target name (e.g. build), any dependencies as a comma-separated list (e.g. install), and the shell commands to run, one per line.
Step 2: Mark Targets as Phony
Leave "Add to .PHONY" checked for targets that do not produce a file matching their name (like build, test, clean) — this is the standard Make convention to avoid conflicts with files of the same name.
Step 3: Add More Targets
Click "Add Target" to define additional targets. Reference earlier target names in a later target's dependencies to chain them together (e.g. build depending on install).
Step 4: Copy or Download
Copy the generated Makefile or download it directly — commands are automatically indented with a real tab character, since Make requires tabs (not spaces) before each recipe line.
