Progress Indicator
by Daniel Westendorf 15 Apr '11

15 Apr '11

Hi all, I want to display a progress indicator (slider looking thing) when playing media, similar to what you would see in iTunes or QuickTime. It will need to update as the media plays. I'm at a bit of a loss on how to go about this in terms of the UI. I've thought about subclassing NSSlider and adding the tweaks there, but maybe there is a better solution? Can someone point me in the right direction? Thanks for the help, Daniel

XCode 4 and ObjC bundles
by Julien Jassaud 14 Apr '11

14 Apr '11

Hi, A while back I tried to port some ObjC examples to MacRuby ( github.com/sojastar/Some-MacRuby-sample-code ). I had to leave parts dealing with C strings in an ObjC bundle that is required in the MacRuby code. The ported samples' building process was a bit complicated with XCode 3 : 1) clone from github 2) run the ObjC bundle Makefile. The Makefile also copied the compiled bundle at the proper location in the build directory. 3) build the project in XCode An inelegant process but it was working fine. Now that XCode 4 adds some random string to the build directory's name I don't know how to point the Makefile to the proper location for copying the bundle. So my question is : what is good practice when it comes to ObjC bundles and MacRuby in XCode 4 ? Is there a way to automate the whole bundle build / copy process ? I tried to modify the "Compile" scheme's "Build" step by adding a pre-action script to it but I don't really know what to put in it. I couldn't even run the Makefile from it. Thanks, Julien Jassaud

How do I get gems into XCode/MacRuby environment?
by Paul Davis 14 Apr '11

14 Apr '11

I'm past the Hello World tutorial, and want to try something useful but I cannot seem to access my gems from within the XCode/MacRuby environment. rubygems is there, as is pp; but not, for instance hpricot. $gem list --local ... hpricot (0.8.1, 0.6.164) ... rack (1.0.1) rails (2.3.5, 2.3.4, 1.2.6) ... Within rb_main.rb: puts "Loading rubygems... #{require 'rubygems'}" #=> true puts "Loading pp... #{require 'pp'}" #=> true but puts "Loading hpricot... #{require 'hpricot'}" gets me "no such file to load -- hpricot (LoadError)" Any hints? Do I need to hunt down the full path?

no superclass method `initialize' with xml-object gem
by Andre Lewis 13 Apr '11

13 Apr '11

Hey all, I hit a snag with the xml-object<http://rubygems.org/gems/xml-object>gem on MacRuby; the code works on MRI 1.9.2. A simple test case: $ macgem install xml-object $ macirb > require "rubygems" require "open-uri" require "xml-object" o=XMLObject.new(open("http://www.w3schools.com/xml/simple.xml")) NoMethodError: super: no superclass method `initialize' for #<XMLObject::Adapters::REXML::Element:0x2004fbea0 ...> /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/xml-object-0.9.93/lib/xml-object/adapters/rexml.rb:32:in `initialize:' /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/xml-object-0.9.93/lib/xml-object/adapters.rb:13:in `block' /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/xml-object-0.9.93/lib/xml-object/adapters.rb:13:in `initialize:' /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/xml-object-0.9.93/lib/xml-object/adapters/rexml.rb:32:in `initialize:' /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/xml-object-0.9.93/lib/xml-object/adapters.rb:13:in `block' /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/xml-object-0.9.93/lib/xml-object/adapters.rb:13:in `initialize:' /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/xml-object-0.9.93/lib/xml-object/adapters/rexml.rb:32:in `initialize:' /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/xml-object-0.9.93/lib/xml-object/adapters/rexml.rb:9:in `new:' /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/xml-object-0.9.93/lib/xml-object.rb:15:in `new:' The same test case works fine on MRI 1.9.2. Let me know if there's a better place to report issues like this. Andre

Concurrent SSL requests -> segfault
by Andre Lewis 12 Apr '11

12 Apr '11

Think I found a bug with Net:HTTP on MacRuby 0.10. Code is here: https://gist.github.com/904320. In a nutshell: * Multiple, concurrent SSL http requests generate a segfault * Multiple, concurrent non-SSL http requests are OK * Multiple, sequential SSL http requests are OK All the scenarios run fine on 1.9.2. Should I file a bug on trac? Andre

MacRuby 0.10 Sqlite3 and Sequel
by Daniel Westendorf 12 Apr '11

12 Apr '11

Hi all, I'm not able to query a Sqlite database using MacRuby and Sequel. Consider the following gist: https://gist.github.com/910989 macruby => 0.10 sequel => 3.22.0 sqlite3 => 1.3.3 I get a response from the the db when I select ALL the rows, but not when I query for one record. It works with MRI 1.9.2. Am I doing something wrong, or is this a bug? Does anyone have some suggestions on what I should do to troubleshoot this or work around it? Thanks, Daniel

Thanks for the input. I found that as a workaround, calling .all() on the end of the query gives me the datas I'm looking for. Thanks for looking!

Validating App Store binaries
by Chris Lloyd 11 Apr '11

11 Apr '11

Hi, I'm trying to submit a MacRuby app that I've been working on to the App Store. I'm using v0.10 and XCode 4. A working binary is produced, however validation fails because of multiple missing symlinks. This happens even with an empty app generated from the scaffold. It seems as though there are two issues: 1. In the macruby.framework directory there is no "Current" version. Creating a symlink for this doesn't work as Xcode gets confused with the separate Info.plist. A workaround I've been using is to rename the "0.10" folder to "Current". 2. None of the Headers are copied in. Am I doing something wrong? This seems like something that somebody must have stumbled into before. Cheers, Chris Lloyd PS. It would be kick-ass if ruby_deploy supported Bundler for getting a list of Gems to include. `macruby_deploy --compile --embed --bundle`

Deploying a macruby document based app
by Rob Ista MM 10 Apr '11

10 Apr '11

Hi all, My document based app runs fine on a mac with the framework installed (macruby 0.10, xcode4) but macruby_deploy seems to fail in building a working app. I think i have implemented all the required overrides, but obviously i am overlooking something Ofc i did set the class in the plist. teh messages i get is: "No document can be created" when i start the deployed app Also when i choose open, the documents of the appropriate types cannot be selected And: trying to select one from the "Open recent" goves the message " .. cannot open files in the "xxxx" format" plz give me some clue's if you have any :))) cheers, Rob Some code: class SubtitleDoc < NSDocument attr_accessor :subtitlesTableView, :oneall, :from, :to, :scan, :replace, :errormessage def windowNibName 'MyDocument' end def init super @subtitles = [] self end def awakeFromNib @subtitlesTableView.dataSource = self end # # read file to raw data and convert to table of subtitles # def readFromData(data, ofType:type, error:error) @subtitles = SubtitleFile.loadFile(NSString.alloc.initWithData(data, encoding:NSUTF8StringEncoding)) return true end # # convert table of subtitles into raw data and return it to filesystem # def dataOfType(type, error:error) data = SubtitleFile.saveFile(@subtitles) data.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion:true) end end

MacRuby crash log
by Gabriel Gilder 09 Apr '11

09 Apr '11

Hi, I'm working on a MacRuby app that occasionally - and somewhat randomly - crashes with a SIGABRT. Not sure if I can create a code sample that recreates the issue, since performing the same actions doesn't always trigger the crash. I've posted the crash log here: https://gist.github.com/910336 Hoping somebody can make more sense of that than me... ;) -Gabriel
