Only "extend self" once on the Homebrew module 2014-06-18 22:41:47 -05:00			`module Homebrew`
Use `module_function` for commands. 2016-09-26 01:44:51 +02:00			`module_function`

Refactor the brew command into one file per command The code was sucking. To the extent that maintenance was hard. It's a lot easier to work with code that is sensibly split at sensible boundaries. So now it is more like that. But the refactor is minimal. Because we don't want you to have more merge hell than absolutely necessary. If you merge you will need to pay attention to brew.h.rb (as it is deleted) and bin/brew (as command logic is gone). It will be painful, but you will just have to help git out by moving any changes around manually. Note compatibility.rb. It ensures that any function renames or removals don't break anything. We're pretty serious about backwards compatibility. And that's because we encourage you to hack around with the innards. And we couldn't do that if we would then just make stuff disappear behind your back. 2010-09-11 20:22:54 +01:00			`def __prefix`

formula: make prefix usually return opt_prefix. Return `opt_prefix` if it exists and `prefix` is not called from within the same formula's `install` or `post_install` methods. Otherwise, fall back to the existing functionality. This avoids the need to use `opt_prefix` etc. everywhere and generally means we don't expose an implementation detail (i.e. the full Cellar path) to dependents that have a habit of hard-coding it. 2016-12-31 16:38:05 +00:00			`puts ARGV.resolved_formulae.map(&:installed_prefix)`
