bmakelib is a collection of useful targets, recipes and variables you can use to augment your Makefiles.

I just released bmakelib v0.6.0 w/ the main highlight being the ability to define enums and validate variable values against them.

➤ Makefile:

define-enum : bmakelib.enum.define( DEPLOY-ENV/dev,staging,prod )
include define-enum

deploy : bmakelib.enum.error-unless-member( DEPLOY-ENV,ENV )
deploy :
	@echo 🚀 Deploying to $(ENV)...

➤ Shell:

$ make ENV=local-laptop deploy
*** 'local-laptop' is not a member of enum 'DEPLOY-ENV'.  Stop.

$ make ENV=prod deploy
🚀 Deploying to prod...
