Class Method Details

.disable(&block) ⇒ Object

Disable Isolate. If a block is provided, isolation will be disabled for the scope of the block.

# File 'lib/isolate.rb', line 16

def self.disable &block
  sandbox.disable(&block)
end

.env ⇒ Object

What environment should be isolated? Consults environment variables ISOLATE_ENV, RAILS_ENV, and RACK_ENV. Defaults to "development" if none are set.

# File 'lib/isolate.rb', line 25

def self.env
  ENV["ISOLATE_ENV"] || ENV["RAILS_ENV"] || ENV["RACK_ENV"] || "development"
end

.now!(options = {}, &block) ⇒ Object

Declare an isolated RubyGems environment, installed in path. Any block given will be instance_evaled, see Isolate::Sandbox#gem and Isolate::Sandbox#environment for the sort of stuff you can do.

Valid options:

:cleanup

Should obsolete gems be removed? Default is true.

:file

Specify an Isolate file to instance_eval. Default is Isolate or config/isolate.rb, whichever is found first. Passing false disables file loading.

:install

Should missing gems be installed? Default is true.

:multiruby

Should Isolate assume that multiple Ruby versions will be used simultaneously? If so, gems will be segregated by Ruby version. Default is false.

:path

Where should isolated gems be kept? Default is "tmp/isolate", and a Ruby version specifier suffix will be added if :multiruby is true.

:name

Like path, but expands to: ~/.gem/repos/#name/ (like ohmygems)

:system

Should system gems be allowed to satisfy dependencies? Default is true.

:verbose

Should Isolate be chatty during installs and nukes? Default is true.

.refresh ⇒ Object

Poke RubyGems, since we’ve probably monkeyed with a bunch of paths and suchlike. Clears paths, loaded specs, and source indexes.

.sandbox ⇒ Object

.sandbox=(o) ⇒ Object

Set the singleton. Intended for Hoe::Isolate and other tools that make their own.
