Recommendations for deprecating private formula

[dandavison]

I have a project which was distributed via a private Homebrew formula for a while, before being accepted into the public Homebrew distribution. I'd like to deprecate the private formula; is there any recommended way to do that?

You can use the deprecate! and disable! methods that we use in Homebrew/core (just do a quick search for those methods and plenty of examples will pop up).

If the formula was migrated to another tap, you can also use a tap_migrations.json file to indicate that the formula moved to another tap. If you do this, trying to install the formula will give the following message:

$ brew install <formula>
Error: No available formula or cask with the name "<formula>".
It was migrated from <user>/<tap> to <new-user>/<new-tap>.
You can access it again by running:
  brew tap <new-user>/<new-tap>
And then you can install it by running:
  brew install <formula>

You can see an example of a tap_migrations.json file in Homebrew/core.

Thanks very much @Rylan12. I added this line

disable! because: "it is now in homebrew core. Please reinstall it as follows:\nbrew untap dandavison/delta\nbrew install git-delta\n"
