# Taps (Third-Party Repositories)
|
|
|
|
The `brew tap` command adds more repositories to the list of formulae that Homebrew tracks, updates,
|
|
and installs from. By default, `tap` assumes that the repositories come from GitHub,
|
|
but the command isn't limited to any one location.
|
|
|
|
## The `brew tap` command
|
|
|
|
* `brew tap` without arguments lists all currently tapped repositories. For
|
|
example:
|
|
|
|
```console
|
|
$ brew tap
|
|
homebrew/cask
|
|
homebrew/core
|
|
petere/postgresql
|
|
```
|
|
|
|
* `brew tap <user>/<repo>` makes a clone of the repository at
|
|
`https://github.com/<user>/homebrew-<repo>` into `$(brew --repository)/Library/Taps`.
|
|
After that, `brew` will be able to work with those formulae as if they were in Homebrew's
|
|
[homebrew/core](https://github.com/Homebrew/homebrew-core) canonical repository.
|
|
You can install and uninstall them with `brew [un]install`, and the formulae are
|
|
automatically updated when you run `brew update`. (See below for details
|
|
about how `brew tap` handles the names of repositories.)
|
|
|
|
* `brew tap <user>/<repo> <URL>` makes a clone of the repository at _URL_.
|
|
Unlike the one-argument version, _URL_ is not assumed to be GitHub, and it
|
|
doesn't have to be HTTP. Any location and any protocol that Git can handle is
|
|
fine, although non-GitHub taps require running `brew tap --force-auto-update <user>/<repo>`
|
|
to enable automatic updating.
|
|
|
|
* `brew tap --repair` migrates tapped formulae from a symlink-based to
|
|
directory-based structure. (This should only need to be run once.)
|
|
|
|
* `brew untap user/repo [user/repo user/repo ...]` removes the given taps. The
|
|
repositories are deleted and `brew` will no longer be aware of their formulae.
|
|
`brew untap` can handle multiple removals at once.
|
|
|
|
## Repository naming conventions and assumptions
|
|
|
|
On GitHub, your repository must be named `homebrew-something` to use
|
|
the one-argument form of `brew tap`. The prefix "homebrew-" is not optional.
|
|
(The two-argument form doesn't have this limitation, but it forces you to
|
|
give the full URL explicitly.)
|
|
|
|
When you use `brew tap` on the command line, however, you can leave out the
|
|
"homebrew-" prefix in commands. That is, `brew tap username/foobar` can be used as a shortcut for the long
|
|
version: `brew tap username/homebrew-foobar`. `brew` will automatically add
|
|
back the "homebrew-" prefix whenever it's necessary.
|
|
|
|
## Formula with duplicate names
|
|
|
|
If your tap contains a formula that is also present in
|
|
[homebrew/core](https://github.com/Homebrew/homebrew-core), that's fine,
|
|
but you would need to specify its fully qualified name in the form
|
|
`<user>/<repo>/<formula>` to install your version.
|
|
|
|
Whenever a `brew install foo` command is issued, `brew` selects which formula
|
|
to use by searching in the following order:
|
|
|
|
* core formulae
|
|
* other taps
|
|
|
|
If you need a formula to be installed from a particular tap, you can use fully
|
|
qualified names to refer to them.
|
|
|
|
If you were to create a tap for an alternative `vim` formula, the behaviour would be:
|
|
|
|
```sh
|
|
brew install vim # installs from homebrew/core
|
|
brew install username/repo/vim # installs from your custom repository
|
|
```
|
|
|
|
As a result, we recommend you give new names to customized formulae if you want to make
|
|
them easier to install. Note that there is (intentionally) no way of replacing
|
|
dependencies of core formulae with those from other taps.
