zlib status
by Patrick Thomson 20 Aug '09

20 Aug '09

Hi everyone, I'm working on porting ext/zlib to MacRuby right now. I took a look at zliby - though it's certainly nice to have a zlib implementation in pure Ruby, zliby seems to be kind of dead in the water (according to its RubyForge page, it hasn't been updated in almost a year). Additionally, zliby is orders of magnitude slower than ext/zlib (decompressing a 2MB gzipped MP3 with ext/zlib took 0.064 seconds with ext/zlib and 73.909 seconds (yes, over a minute) with zliby). Porting the library will take a little while, as for performance reasons zlib needs to use ByteStrings. So be patient, and it'll be here before you know it. :-) -- Patrick >> > We are almost there, Etc, Zlib and Socket are still missing. >> > Last I heard, Laurent had a "plan" for Zlib, knowing him, it's probably a >> > great and efficient idea. >> > Make sure to check with him before starting on that.

Fixing ext/json
by dan sinclair 20 Aug '09

20 Aug '09

Hello, I've been taking a poke at ext/json for the last few days attempting to get JSON support working again. I've got it compiling but have run into an issue with memory management and the garbage collector that I've been unable to get past. I've attached my current diff of changes to get JSON working. With this diff applied requiring json will crash with: unknown: [BUG] destination 0x100feb300 isn't in the auto zone I've tracked it down to ext/json/lib/json/common.rb line 59 (at least, it never gets past that line that I've seen) self.state = generator::State Commenting out this line gets further (require works and I can turn {"a" => 1} into JSON. Missing module_function causes JSON.parse to fail). My test file is: puts "Requiring" require 'json' puts "Required" require 'pp' puts "to_json" a = {"a" => 1}.to_json puts "parse" pp JSON.parse(a) puts "done" Thoughts? Thanks, dan

Any volunteers to help maintain http://www.macruby.org?
by Jordan K. Hubbard 19 Aug '09

19 Aug '09

As folks can see, there IS a blog there, but it was last updated back in March, Laurent & friends preferring to use email for communicating status. Since we have a blog, however, it also makes sense to keep it relatively current for those folks who are new to the macruby.org site and looking for signs of life. This is obviously not a highly technical task we're talking about, just transcribing the highlights of the email status reports and whatever else seems to be topical (the recent merge of the experimental branch to trunk, for example). This would also be a fine task for a more junior project member looking for an opportunity to start contributing to the project without having to grok the mysteries of MacRuby's internals first, and it's an important contribution since it will help keep folks who enjoy scanning blogs (but not subscribing to mailing lists) up to date! Any takers? - Jordan

github mirror
by Claudio Poli 17 Aug '09

17 Aug '09

hi everyone, I would like to apologize for the trunk mirror on github ( http://github.com/masterkain/macruby/commits/master ) not getting up to date, I got no notification that the script used to mirror from svn wasn't working anymore due to a public key change. Now it's fixed, I had a small talk with mojombo that says that if you don't see the most recent commits on github web is because there was an outage some minutes ago and the web interface has yet to caugh up with the on-disk repo. thanks.

macruby-bundle-example
by Clay Bridges 15 Aug '09

Hi all, When I was first figuring out how to call my ObjC classes from MacRuby, I greatly benefited from Pieter de Bie's excellent minimal, xcode-free example of this, macruby-bundle-example. I spiffed it up a bit. Here's the github link: http://github.com/diffengr/macruby-bundle-example. It might be helpful to link to this or its like in future tutorials on this subject. Cheers, Clay
