macirb or not working with awesome_print
"DietRB" or "macirb" don't seem to be working after I install "gem awesome_print" I have to "gem uninstall awesome_print" to get it to work.

Hi Brad, What's happening here is that the 'gem' command that ships with MacRuby is named 'macgem'. However, 'macirb' still looks at the same .irbrc file that the system 'irb' command does. So, if you've put in a require for awesome_print into your .irbrc, then 'macirb' will look for it but not find it. Try running 'macgem install awesome_print' instead and let us know how it goes.

I didn't know about awesome_print, and it's kind of blown my mind. The default irb formatting is great. Only, I cannot get it to work in macirb. It looks like the internals of IRB is completely different. Has anyone had an luck with this? Matt On Oct 6, 2010, at 2:10 AM, Eloy Duran wrote:

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.

Aha, I see. Well, first let me say that, as you noticed, the internals of IRB are indeed different than the one from MRI. This is a rewrite of IRB called DietRB http://github.com/alloy/dietrb, which was mentioned in the changelog, but not the announcement. I haven’t worked on completing the API and no documentation yet, but that will happen before the MacRuby 0.8 release. In the meantime, I will release new gem versions https://rubygems.org/gems/dietrb, and please do file tickets on the MacRuby Trac or github issues page! On to the problem at hand, I won’t support this use in DietRB, because it’s not a proper API anyways. Please try the following, in your .irbrc: require "rubygems" require "ap" if IRB.version.include?('DietRB') # MacRuby code class AwesomePrintFormatter < IRB::Formatter def inspect_object(object) object.awesome_inspect end end IRB.formatter = AwesomePrintFormatter.new else # MRI code end Regarding the way to differentiate between two implementations. I think checking if an object responds to a method is the way to go, if you are going to call that method. In this case, maybe some day you'll require a gem which defines a Kernel#framework method, breaking your condition. So for these kinds of things I generally use: if defined?(MACRUBY_VERSION), or in this case you can differentiate with the IRB.version string, meaning that if you would install the DietRB gem on MRI 1.9, it would keep working. Thanks for the report! Cheers, Eloy On Wed, Oct 6, 2010 at 6:25 PM, Matt Massicotte <massicotte@apple.com> wrote:

Success! Thanks Eloy. Matt On Oct 6, 2010, at 11:06 AM, Eloy Duran wrote:
Aha, I see. Well, first let me say that, as you noticed, the internals of IRB are indeed different than the one from MRI. This is a rewrite of IRB called DietRB http://github.com/alloy/dietrb, which was mentioned in the changelog, but not the announcement. I haven’t worked on completing the API and no documentation yet, but that will happen before the MacRuby 0.8 release. In the meantime, I will release new gem versions https://rubygems.org/gems/dietrb, and please do file tickets on the MacRuby Trac or github issues page!
On to the problem at hand, I won’t support this use in DietRB, because it’s not a proper API anyways. Please try the following, in your .irbrc:
require "rubygems" require "ap"
if IRB.version.include?('DietRB') # MacRuby code class AwesomePrintFormatter < IRB::Formatter def inspect_object(object) object.awesome_inspect end end IRB.formatter = AwesomePrintFormatter.new else # MRI code end
Regarding the way to differentiate between two implementations. I think checking if an object responds to a method is the way to go, if you are going to call that method. In this case, maybe some day you'll require a gem which defines a Kernel#framework method, breaking your condition. So for these kinds of things I generally use: if defined?(MACRUBY_VERSION), or in this case you can differentiate with the IRB.version string, meaning that if you would install the DietRB gem on MRI 1.9, it would keep working.
Thanks for the report!
Cheers, Eloy

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.

I did, in the email that you replied on. Could you please send some more info about what really happens? Eloy

I didn't know about awesome_print, and it's kind of blown my mind. The default irb formatting is great. Only, I cannot get it to work in macirb. It looks like the internals of IRB is completely different. Has anyone had an luck with this? Matt On Oct 6, 2010, at 2:10 AM, Eloy Duran wrote:

Hi Brad, What's happening here is that the 'gem' command that ships with MacRuby is named 'macgem'. However, 'macirb' still looks at the same .irbrc file that the system 'irb' command does. So, if you've put in a require for awesome_print into your .irbrc, then 'macirb' will look for it but not find it. Try running 'macgem install awesome_print' instead and let us know how it goes. Cheers, Josh

"DietRB" or "macirb" don't seem to be working after I install "gem awesome_print" I have to "gem uninstall awesome_print" to get it to work. I am guessing DietRB may be the name of the IRB but it is still launches with "macirb"
