actions.mk

# actions.mk — dynamic target generation for verb+modifier pattern
#
# Usage — define a recipe block, then register it:
#
#   define build.frontend
#   	@echo "Building frontend..."
#   	bun run build
#   endef
#   $(call register,build,frontend)
#
# With prerequisites:
#   $(call register,build,frontend,$(_HIDE)stamp.frontend)
#
# Then declare the verb to wire everything up:
#   $(call declare_verb,build)
