A makefile that regenerates the public/ folder for Hugo sites, optimizes images and prepares the git commit for GitHub Pages.

Makefile-generate-HGP-site

SHELL:=/bin/bash
BASEDIR=$(CURDIR)
OUTPUTDIR=$(BASEDIR)/public

optipng = find $(OUTPUTDIR) -name '*.png' -print0 | xargs -0 -P8 -n2 optipng -o5 -strip all -quiet
optijpg = find $(OUTPUTDIR) -name '*.jpg' -print0 | xargs -0 -P8 -n2 jpegoptim --strip-all -m30 -q

site:

	@echo "Deleting files from old publication"
	rm -rf $(OUTPUTDIR)/*

	@echo "Generating site"
	hugo

	@echo "Optimizing images"
	$(call optijpg)
	$(call optipng)
	
	@echo "Preparing commit"
	cd $(OUTPUTDIR)/ && git add . && git status && git commit -m "$(m)"

If you use a custom domain with GitHub Pages, ensure that your Hugo site contains the CNAME file inside root/static/. You can also put your README.md there.
