Module: Hoe::Isolate

Defined in:
lib/hoe/isolate.rb

Overview

This module is a Hoe plugin. You can set its attributes in your Rakefile’s Hoe spec, like this:

Hoe.plugin :isolate

Hoe.spec "myproj" do
  self.isolate_dir = "tmp/isolated"
end

NOTE! The Isolate plugin is a little bit special: It messes with the plugin ordering to make sure that it comes before everything else.

#isolate_dir ⇒ Object

Where should Isolate, um, isolate? [default: "tmp/isolate"] FIX: consider removing this and allowing isolate_options instead.
