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)"

Prerequisites:

• optipng
• jpegoptim
• Hugo site

What this Makefile does:

1. Removes all files and folders from public/, leaving hidden files (like .git) intact
2. Generates your Hugo site with the hugo command
3. Optimizes png and jpg images according to the flags passed (see manpages for optipng and jpegoptim to understand these)
4. In public/, creates a new commit with your message

Usage

Do make site m="<your message>"

This Makefile does not do git push for you. If everything looks ok after the Makefile runs, do this manually.

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.
