Visibility of ruby methods to objective-C delegates
by Michael Pitra 02 Feb '10

02 Feb '10

I'm trying to do something similar to this example: http://code.reflectivepixel.com/post/103638573/require-hotcocoa-framework-w… Code excerpt: require 'hotcocoa' framework 'webkit' class Application include HotCocoa FULL={:expand => [:width,:height]} BASE=<<-END <html><head><style type="text/css"> * { font-family: Monaco; } </style><script type="text/javascript"> function say(arg) { window.TheBridge.click(arg);} </script> </head><body><h3>Ruby JavaScript Bridge</h3> <a href="#" onclick="say('hi')">tell</a></body></html> END def click(arg) #called from javascript root = document.createElement("div"); root.innerHTML="javascript tells ruby: #{arg}" document.body.appendChild(root) end def document @web_view.mainFrame.DOMDocument end def self.webScriptNameForSelector(sel) #hide : in name sel.to_s.sub(/:$/,'') if is_available_selector?(sel) end def self.isSelectorExcludedFromWebScript(sel) ! is_available_selector?(sel) end def self.isKeyExcludedFromWebScript(key) true end def self.is_available_selector?(sel) ['click:'].include?(sel.to_s) end def start application :name => "MyBridge" do |app| app.delegate = self window :title => "MyBridge", :frame => [10, 620, 330, 230] do |win| win << @web_view=web_view(:layout => FULL) do |wv| wv.mainFrame.loadHTMLString BASE, baseURL: nil wv.frameLoadDelegate=self wso=wv.windowScriptObject #make visible to JS wso.setValue(self, forKey:"TheBridge") end win.will_close { exit } end end end end Application.new.start Clicking on "tell" does not work. It seems, that the selector for "click:" is not found. When logging the selector values in self.isSelectorExcludedFromWebScript(sel), the "click:" selector is not amongst the results. What am I missing here? Regards, Michael

[MacRuby] #593: Website: use git svn clone

#593: Website: use git svn clone ----------------------------------------+----------------------------------- Reporter: ernest.prabhakar@… | Owner: lsansonetti@… Type: enhancement | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: ----------------------------------------+----------------------------------- Proposed change to https://www.macruby.org/source.html While "git clone" of the mirror works great for working off of trunk, it is often useful to have a direct pull of the SVN repository via, e.g.: git svn clone http://svn.macosforge.org/repository/ruby/MacRuby/trunk MacRuby.git I believe this is necessary to push changes back upstream, so why not suggest that first? -- Ticket URL: <http://www.macruby.org/trac/ticket/593> MacRuby <http://macruby.org/>

MacRuby examples
by Matt Aimonetti 02 Feb '10

02 Feb '10

I just realized that I forgot to mention some of Macruby related posts I worked on, so here is a quick list: * Undo/Redo with MacRuby using NSUndoManager http://merbist.com/2010/02/02/undoredo-in-macruby/ * How to detect Cylons with MacRuby/ new 0.6 debugger http://merbist.com/2010/01/18/how-to-detect-cylons-with-macruby/ * Controlling iTunes with MacRuby http://merbist.com/2010/01/17/controlling-itunes-with-macruby/ * IM countdown with MacRuby / controlling iChat from MacRuby http://merbist.com/2009/12/31/im-new-year-count-down-with-macruby/ * Language detector using Foundations' tokenizer: http://merbist.com/2009/12/29/fun-with-macruby/ I need to convert these posts and put them on the main website, but I figured some of you might be interested in reading them now. - Matt p.s: I'm making some good progress on the O'Reilly book but these kind of things take a while and I'm still working on chapter 2 (out of 7).

Requiring dynamic libraries trouble
by Darrin Eden 02 Feb '10

02 Feb '10

Hi, I'm attempting to use a dynamic library. On my workstation it works well. Yet as soon as I try other computers it fails to behave as expected. I have a feeling I'm missing something trivial, but for the life of me I'm not seeing it: <http://gist.github.com/292829>. Many thanks, -- Darrin

Requirements for Interface Builder to correctly parse MacRuby files?
by Paul Howson 02 Feb '10

02 Feb '10

Hello Laurent et al, In an attempt to ease code management for a large document class, I split the code for my NSDocument subclass into a number of separate Ruby files. e.g. MyDocument-base.rb, MyDocument-commands.rb, and so on, reopening the Ruby class and adding more methods in each file. When the class was in a single source file (eg. MyDocument.rb), Interface Builder would correctly parse this and recognise outlets and action methods. Splitting the class into separate files had the effect of causing Interface Builder to no longer recognise outlets and action methods. Can you please explain how and when IB parses Ruby source files and why splitting a class into separate files breaks the parsing? Is this documented somewhere? Any suggestions for a way around this? Thanks, Paul Howson Queensland Australia

trunk now requires a new LLVM
by Laurent Sansonetti 02 Feb '10

02 Feb '10

For those who follow trunk, please note that as of r3408 a new LLVM revision is required: r89156. Please follow the instructions in the README.rdoc file that have been upgraded. For those who follow the nightly builds, I wrote a message to Claudio, maybe the upcoming build will be good :-) Laurent

[MacRuby] #378: Macruby 0.5 allows instantiation of a Module instance
by MacRuby 02 Feb '10

02 Feb '10

#378: Macruby 0.5 allows instantiation of a Module instance ---------------------------------------+------------------------------------ Reporter: keith.gautreaux@… | Owner: lsansonetti@… Type: defect | Status: new Priority: minor | Milestone: MacRuby 0.5 Component: MacRuby | Keywords: ---------------------------------------+------------------------------------ It seems that MacRuby treats modules differently than Ruby 1.9. You shouldn't be able to instantiate a named module using the new method, i.e. {{{ A = Module.new do def meth1 "hello" end end }}} YARV: {{{ a = A.new => NoMethodError: undefined method `new' for A:Module }}} but it does in MacRuby returning an instance of A:Module which responds to the meth1 call: {{{ a.meth1 =>"hello" }}} I believe the proper behavior (based on the 1.9 pickaxe documentation) is to allow extending of an object with A's methods but not instantiation. {{{ a = NSObject.new a.extend(A) a.meth1 => "hello" }}} Once I figure out how to write specs I'll see if I can submit a failing one. -- Ticket URL: <http://www.macruby.org/trac/ticket/378> MacRuby <http://macruby.org/>

Packaging a HotCocoa application without the standard library
by isaac kearse 02 Feb '10

02 Feb '10

Hey Guys, Just wrote a few blog posts about a HotCocoa app I just released, and how I packaged it up: http://isaac.kearse.co.nz/2010/01/31/stopwatch/ http://isaac.kearse.co.nz/2010/02/01/packaging-hotcocoa/ Interested in getting feedback about the way I embedded MacRuby & HotCocoa in this app. (also feedback about the app is welcome) I was thinking about patching HotCocoa to enable this out of the box because at the moment it seems to copy across the MacRuby framework instead of using macruby_deploy. Cheers, Isaac

[MacRuby] #571: #respond_to? should return false for unimplemented methods
by MacRuby 01 Feb '10

#571: #respond_to? should return false for unimplemented methods ---------------------------------+------------------------------------------ Reporter: honglilai@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: ---------------------------------+------------------------------------------ MRI >= 1.9.2's #respond_to? method now returns false for unimplemented methods. By "unimplemented" I mean methods which are #defined as rb_f_notimplement in the MRI 1.9 source code. rb_f_notimplemented is a method which raises NotImplementedErrror. An example of this is Process.fork, implemented on MRI 1.9 as rb_f_fork. The #fork method is defined on all platforms, even on platforms where fork is not actually supported (i.e. rb_f_fork is #defined to rb_f_notimplemented). However Process.respond_to?(:fork) now returns false instead of true on these platforms. MacRuby should follow this behavior. -- Ticket URL: <http://www.macruby.org/trac/ticket/571> MacRuby <http://macruby.org/>

0.5 status... good to go!
by Laurent Sansonetti 01 Feb '10

01 Feb '10

Hi guys, It has been a long time since I did a status report here, but I have been busy :) Here is a status about what happened since 0.5 beta 2 until we started working on 0.6. I think 0.5 is good enough to be released as final now. I will prepare the release and hopefully it will go out later today. Highlights: - HotCocoa support is back! Also, HotCocoa is no longer developed in the MacRuby repository but on GitHub: http://github.com/richkilmer/hotcocoa . We hope that by being on GitHub, HotCocoa will evolve faster. Be sure to do a 'macrake install hotcocoa'. - AOT compiler is more stable, supports compilation of multiple Ruby files into shared/dynamic libraries. It is also documented in a man- page, be sure to check it out for a detailed list of options and some use case examples. - GCD API is complete, frozen and fully documented. Stay tuned for GCD tutorials on the website. - Better runtime symbolication (backtraces) by emitting DWARF annotations. - Numerous miscellaneous bug fixes! Changes: - macrubyc: better CPU architecture check - ruby catch/throw statements now use specialized C++ exceptions instead of setjmp/longjmp - macrubyc: make sure compilation works if paths contain spaces - macrubyc: no longer use llvm-config for C++ compilation flags but rbconfig - fixed Module#method_defined? - rake build: ignore RUBYOPT - templates: updated rb_main.rb to honor .rbo files - GCD: ignore exceptions raised inside GCD blocks - do not cache blocks for functions - openssl extention: misc fixes - #throw must clear the current VM exception before unwinding the stack - GCD: fixed a few race conditions - define the GC and ObjectSpace API as module functions - start tagging non-RObject classes to not use ivar slots - added Module#__properties__ to return the list of Objective-C properties - never overwrite -[NSObject hash] - when registering a method as a BS informal protocol, pad the signature with @ in case the ruby arity is greater than the objc one - property handle missing 64-bit bridgesupport annotations in informal protocols for pointer types - fixed a bug when inserting an object into a KVO array - str.split('') should split into characters - honor nil backtraces when printing an uncaught exception - misc KVC bug fixes - templates: switched from .nib to .xib - GCD: block shared/dynamic variables are now copied - GCD: Queue#dispatch and Group#dispatch are gone. Replacements: Queue#async(group=nil) and Queue#sync - macrubyc: don't forgot to initialize load path and program name - GCD: aliased Queue#to_s to Queue#label - emit DWARF metadata at compilation time and use it to establish backtracing later at runtime - fixed Time marshalling - GCD: don't try to release a NULL semaphore - fixed a whole lot of crashes on 32-bit - macrubyc: added support for AOT compiled source code objects in #require - macrubyc: added manpage - GCD: when finalizing a dispatch semaphore, re-equilibrate before release to avoid a crash - fixed #method_missing and #respond_to? for NSProxy-based objects - fixed some class variables bugs - when changing the visibility of a method and duplicating its entry in the lookup table, be sure to keep the same flags too - added Pointer out-of-bounds access check - optimized #to_path conversion - fixed Fixnum#odd? and Fixnum#even? - fixed a thread-safety bug in RoxorCore::retype_method() - #extend_object: honor nested modules - added some basic support for multibyte regexps - FFI::Library#attach_function: the first argument can also be a symbol - macrubyc: generate better tmpfiles to allow multiple compilations of the same project - GCD: added rdoc documentation for all APIs - fixed a bunch of super-dispatch bugs - added preliminary (not complete) support for objc methods aliasing - fixed a bug when accessing regexp match special variables - fixed a bug in String#dump in case the receiver is a bytestring - fixed a bug in the #send method inliner where protected methods would not be callable - removed HotCocoa from the repository. It is now living on github as a separate gem. - implemented Thread.kill and Thread.exit - rb_str_dup(): in case the receiver is not a pure CF string, send - mutableCopy - Thread.list: do not return the internal thread list but a copy instead - don't use #delete to remove a thread from the internal list since it might trigger custom methods which might acquire the core lock and therefore cause a deadlock - implemented #[] and #[]= as shortcuts for objectForKey: and setObject:forKey: - GCD: added sources API - do not uncache a block if the context (self) is different - templates: do not load rb_main.rb twice Laurent
