try it for sparksource

  • read the original page [[https://diamantidis.github.io/tips/2020/07/01/list-makefile-targets][all targets]]
  • default make target #+BEGIN_SRC makefile

    the default target of make is all

    so when is do make, it runs make all

    change it to help

    .DEFAULT_GOAL := help .PHONY: help

help: @grep -E ‘^[a-zA-Z0-9_-]+:.?## .$$’ $(MAKEFILE_LIST)
| sed -n ‘s/^(.): (.)##(.*)/\1\3/p’
| column -t -s ‘ ‘ #+END_SRC

  • add comment for each target as #+BEGIN_SRC makefile install: ## Install @echo “Installing…”

run: ## Run @echo “Running…” #+END_SRC

  • the final result is #+BEGIN_SRC shell make #output:

    install Install

    run Run

    #+END_SRC
