s/require 'brewkit'/require 'formula'/g brewkit.rb changes ENV destructively, so lets not do that everytime a formula is required. Now it's possible for other tools to require a formula description without worrying about side-effects. 2009-10-15 08:07:12 +00:00			`require 'formula'`

Dependency resolution with fancy syntax Is it a DSL? No. But people call it that apparently. To add a dependency: class Doe <Formula depends_on 'ray' depends_on 'mee' => :optional depends_on 'far' => :recommended depends_on Sew.new end Sew would be a formula you have defined in this Formula file. This is useful, eg. see Python's formula. Formula specified in this fashion cannot be linked into the HOMEBREW_PREFIX, they are considered private libraries. This allows you to create custom installations that are very specific to your formula. More features to come, like specifying versions 2009-09-18 18:16:39 +00:00			`depends_on 'neon'`
