[MacRuby-devel] macirb or not working with awesome_print

[Matt Massicotte]

I wasn't clear at all, sorry.  I can't get *automatic* formatting to work.  My .irbrc file looks like this:

require "rubygems"
require "ap"

unless Kernel.respond_to?(:framework) #admitted ugly hack
  require 'irb/completion'
  
  IRB::Irb.class_eval do
    def output_value
      ap @context.last_value
    end
  end
  
end

This makes the default irb formatting us awesome_print.  I got this from the awesome_print github page.  If I move the class_eval statement out of the conditional, I get this:

matt$ macirb
/Users/matt/.irbrc:1:in `<main>': uninitialized constant IRB::Irb (NameError)
	from /usr/local/bin/macirb:13:in `block'
	from /usr/local/bin/macirb:9:in `block'
	from /usr/local/bin/macirb:3:in `<main>'

As an aside:
I have a ton of code that needs to run under both macruby and rubycocoa.  Due to the ObjC calling conventions and OSX module stuff, portability is kind of a pain.  I use the Kernel.respond_to?(:framework) construct often, but I welcome better suggestions.

So, if you've put in a require for awesome_print into your .irbrc, then 'macirb' will look for it but not find it.
