Notes on creating a new package

I'm trying to package whisper.cpp as a library for homebrew

• Formula cookbook

• Adding software to homebrew

• brew create --autotools https://github.com/ggerganov/whisper.cpp/archive/refs/tags/v1.4.0.tar.gz

  • created the package as lib-whispercpp, I'm not sure if that's because of something I did earlier or if it auto-decided that's what the package name should have been
  • Later on, I changed it to libwhisper because that seems to be the best match for their naming conventions

• I found it helpful to clone homebrew-core so I could run greps against the already-existing formulae and search for useful tips and tricks

• I made a directory and created a very short makefile to save commands I used frequently:

.PHONY: edit
edit:
	nvim /opt/homebrew/Library/Taps/homebrew/homebrew-core/Formula/libwhisper.rb

.PHONY: audit
audit:
	brew audit --new libwhisper

.PHONY: install
install:
	brew install --build-from-source libwhisper

.PHONY: install
uninstall:
	- brew uninstall libwhisper

.PHONY: test
test:
	# I ended up writing a small C program to use both as the test in the
	# formula, as well as to test the installed library
	/usr/bin/clang test.c -I/opt/homebrew/Cellar/libwhisper/1.4.0/include -L/opt/homebrew/Cellar/libwhisper/1.4.0/lib -lwhisper -o test
	./test
	brew test libwhisper

I wanted to create a tap so that I could install in the meantime. for use in blisper (and maybe other experiments), so I:

• created a repository: gh repo create --public llimllib/homebrew-whisper
  • link
• added it as a remote: git remote add origin https://github.com/llimllib/homebrew-whisper.git
  • (I had forgotten the --src arg to gh repo create
• pushed a Formula directory containing the formula I'd just built, a README, and a few gitihub actions I took from brew tap-new llimllib/deleteme
  • I didn't expect that latter command to install into the brew directory, but it did; I went in it to inspect and copy their template files then deleted it after
• To test the repo, I uninstalled libwhisper that I had done locally, and ran:
  • brew install llimllib/whisper/libwhisper
  • which worked! neato.
