Reset Homebrew Formula

Question

While trying to install FreeTDS via Homebrew, I ran brew edit freetds. I edited the file. I'd like to restore the Recipe file (freetds.rb) to it's orinal state in case I introduced a typo into it.

Is there a way to reset a brew formula file?

Thanks

Answer 1

Homebrew recipes are managed via Git, so you can just git checkout freetds.rb to wipe out your local changes.

Answer 2

You need to reset your Cellar git repo.

cd `brew --cellar`
git reset --hard HEAD
brew upgrade <formula>

That should do it!

Answer 3

For Homebrew version 2.1.4 on macOS Mojave the following command will work for core formulas:

git -C $(brew --repo)/Library/Taps/homebrew/homebrew-core checkout Formula/$FORMULA_NAME.rb

Where $FORMULA_NAME is the name of the formula you have edited.
