macruby and sqlite3 gem
by Tim Rand 31 Mar '09

31 Mar '09

I was worried that it was an IO issue with macruby, which is why I am very excited that the 0.5 version is going to be address the IO system--hopefully it will help with this issue. I would love to help, but an issue spanning macruby, obj-c, sqlite3, and possibly C is really stretching my abilities. On the subject of sqlite wrappers in objective-C. I tried several that I found on the sqlite webpage (the have a long list of wrappers in several languages including obj-c). But it appears that most if not all are not being maintained and are not up to date and don't work with Leopard. If anyone knows of a light weight obj-c wrapper for sqlite3 that works in Leopard, please let us know. If I had some code that works to look at, I should be able to adapt it for macruby. framework 'QuickLite.framework' # fails with the error below framework 'QuickLite' # fails can't find file Error Domain=NSCocoaErrorDomain Code=3585 UserInfo=0x800621ae0 "The bundle “QuickLite” could not be loaded because it does not contain a version for the current architecture."

MacRuby and XML-RPC
by Stéphane Wirtel 31 Mar '09

Hi all, I am trying to create a small xml-rpc client with macruby, but I got this error. stargate:test_ruby stephane$ ./client.rb /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/1.9.1/ rexml/attribute.rb:18:in `<class:Attribute>': uninitialized constant REXML::Attribute::NAME_STR (NameError) from /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/ 1.9.1/rexml/attribute.rb:9:in `<module:REXML>' from /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/ 1.9.1/rexml/attribute.rb:4:in `<top (required)>' from /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/ 1.9.1/rexml/element.rb:3:in `require' from /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/ 1.9.1/rexml/element.rb:3:in `<top (required)>' from /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/ 1.9.1/rexml/document.rb:1:in `require' from /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/ 1.9.1/rexml/document.rb:1:in `<top (required)>' from /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/ 1.9.1/xmlrpc/parser.rb:700:in `require' from /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/ 1.9.1/xmlrpc/parser.rb:700:in `initialize' from /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/ 1.9.1/xmlrpc/utils.rb:48:in `new' from /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/ 1.9.1/xmlrpc/utils.rb:48:in `parser' from /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/ 1.9.1/xmlrpc/client.rb:421:in `call2' from /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/ 1.9.1/xmlrpc/client.rb:410:in `call' from ./client.rb:6:in `<main>' Here is the source code of my small client #!/usr/local/bin/macruby require "xmlrpc/client" server = XMLRPC::Client.new("tiny.my.odoo.com", "/xmlrpc/common", 8069) puts server.call("about") This code works fine with the standard ruby. So, I have downloaded the trunk version and I will try to fix this bug, and make a patch. Regards, Stephane

branches/experimental
by Laurent Sansonetti 30 Mar '09

30 Mar '09

Hi guys, As some of you already noticed we have been working on a branch for a few weeks and I thought it's now time to describe what has been done and were we are going exactly. I wrote a blog entry here: http://www.macruby.org/blog/2009/03/28/experimental-branch.html 2 big features in this branch: a LLVM-based JIT compiler and a new IO subsystem. Obviously performance-related, we really need to be faster. Current status of the branch: - The compiler is now able to pass most of the Ruby AST. It compiles nodes directly from the parser in a lazy fashion. - Only JIT compilation for the moment (AOT is planned for later). - The VM is still under development, it's not as complete as the compiler yet. - Early performance benchmarks are very promising. - By the time of this writing, we pass the vast majority of the language RubySpecs (a week ago we weren't even able to even bootstrap mspec!), about 1190 expectations. Work is very active in this area, we are also making sure the specs do run with the original Ruby 1.9 and writing missing specs. - The new IO subsystem is mostly functional, but there are still many methods that are not implemented yet and we are working on this. Once it will be complete we will integrate a default runloop in the VM and expose asynchronous IOs. For the near future, the goals are: - Improving the compiler. Currently compile time has not really been optimized yet. - Be able to run IRB. We are almost there. - Remove the libffi code used to call C/ObjC implementations and instead JIT compile stubs and insert them in the dispatcher cache. We should be way closer to ObjC then (and maybe faster once we enable secondary compilations of hotspots and inline the stubs). - Rewrite the BridgeSupport side using LLVM types. - Implement full concurrent threading! (this is a big one :-)). - And many more (check the TODO file for more info). Once we arrive at a point when the branch is as functional as trunk, it will be merged in trunk and we will then work on stabilizing it, to later on release it as 0.5. The schedule for this release is unknown, it will be released when it will be ready (preferably this year though). If you want to help let me know! Laurent

helping out
by John Shea 30 Mar '09

30 Mar '09

Hi Matt, you said: > If you were thinking about helping out, be reassured, help is always welcome ;) I would happily spend some time on MacRuby, but I have no idea where to start. I downloaded the experimental branch - was not really sure to go from there but tried running some simple ruby code with the miniruby executable - it hung so I assume I was doing something wrong. Anyway I was wondering whether you could give me a quick run down on how to start investigating learning and experimenting with the experimental branch. Any links would be helpful. I would like to start as simple as possible - but down the track one particular part that i would be interested in is tracing the dispatch from bridgesupport method to opengl function. I can't really spend much time until after the Amsterdam conference however. Speaking of which is it you that cannot make it? Pity if so - I was looking fwd to your talk as I have some very flakey code which interfaces with some traditional (ie non REST) webservices - I was hoping for some (yet more) tips ;-). Cheers, J

Rubyspec - Google Summer of Code
by Federico Builes 30 Mar '09

30 Mar '09

(This message is being sent to several lists, I apologize if you get more than one copy). The Rubyspec project (http://rubyspec.org) is interested in finding one student to work with us this year in the Google Summer of Code. We'll be applying under the Ruby on Rails organization, you can find more information at: http://socghop.appspot.com/org/show/google/gsoc2009/rails A few months ago we merged the 1.8/1.9 specs and currently, Ruby 1.9 is not able to get a complete run on the specs. We'd like to start there, making sure that we can get a complete run with failures (instead of crashes/freezes). After having that, the student could start working on fixing some of the failing specs and writing new ones that target 1.9 specifically. The ideal candidate would be someone experienced with RSpec-style testing (we use our own system called MSpec), familiar with Ruby and interested in spending his summer helping the Ruby community. I'll be happy to answer to your ideas/comments/suggestions at federico.builes(a)gmail.com. We also have a mailing list and IRC channel that you might want to check out: * http://groups.google.com/group/rubyspec * #rubyspec @ irc.freenode.net * http://github.com/rubyspec If you're interested in applying please check out the Google Summer of Code application at: http://socghop.appspot.com/ -- Federico

[MacRuby] #238: rdoc memleaks & segfaults when installing gems

#238: rdoc memleaks & segfaults when installing gems --------------------------------+------------------------------------------- Reporter: ted@… | Owner: lsansonetti@… Type: defect | Status: new Priority: critical | Milestone: Component: MacRuby | Keywords: gem install rdoc --------------------------------+------------------------------------------- Was trying to install some dependencies for a gem i am working on (so i can test it on macruby). I get a lot of mentions that macruby has a non- zero refcount (all the info is in the trace). http://gist.github.com/87225 installing w/ --no-rdoc & --no-ri works just fine :) -- Ticket URL: <http://www.macruby.org/trac/ticket/238> MacRuby <http://macruby.org/>

new website!
by Laurent Sansonetti 28 Mar '09

Hi guys, I'm glad to introduce you our new website! http://macruby.org It's written with webby and it's very easy to maintain it. It was implemented so that people can easily contribute changes. Dependencies: $ sudo gem install coderay $ sudo gem install webby To get the sources: $ svn co http://svn.macosforge.org/repository/ruby/MacRubyWebsite/trunk macruby-website To build it + start a local web browser + open a new browser window and refresh the server when a file changes: $ cd macruby-website $ webby autobuild Feel free to check it out and if you want to provide a tutorial/recipe please send your patch! I would like to personally thank: John Athayde (design), Rich Kilmer (implementation) and William Siegrist (server hosting). Enjoy, Laurent
