homebrew-mode

Emacs minor mode for editing Homebrew formulae.

setup

(add-to-list 'load-path "/where/is/homebrew-mode")
(require 'homebrew-mode)
(global-homebrew-mode)

The command prefix is C-c C-h. These are the commands currently mapped to it:

C-c C-h f: Download the source file(s) for the formula in the current buffer.
C-c C-h u: Download and unpack the source file(s) for the formula in the current buffer.
C-c C-h i: Install the formula in the current buffer.
C-c C-h r: Uninstall the formula in the current buffer.
C-c C-h t: Run the test for the formula in the current buffer.
C-c C-h a: Audit the formula in the current buffer.
C-c C-h s: Open a new buffer running the Homebrew Interactive Shell (brew irb).
C-c C-h c: Open a dired buffer in the Homebrew cache (default /Library/Caches/Homebrew).
C-c C-h d: Add depends_on lines for the specified formulae. Call with one prefix (C-u) argument to make them build-time dependencies; call with two (C-u C-u) for run-time.
C-c C-h p: Insert Python resource blocks (requires poet, installed with pip install homebrew-pypi-poet).

These are just the most important variables; run M-x customize-group RET homebrew-mode to see the rest.

If you’re using Linuxbrew or a non-standard prefix on Mac OS, you’ll need to update homebrew-prefix to point at your brew –-prefix.
If you’re using Linuxbrew or have your cache in a non-standard location on Mac OS, update homebrew-cache-dir.
If you want to turn on whitespace-mode when editing formulae that have inline patches, set homebrew-patch-whitespace-mode to t. It’s off by default since it looks ugly.
