by david kramf 09 Dec '12

09 Dec '12

Hi, In the copied below code only the awakeFromNib is executed . Can someone explain me what do I do wrong ? Window is displayed and I expected all other methods to be called. Thanks, David class MyController < NSWindowController attr_accessor :window def awakeFromNib @window.delegate = self puts " at end of awake from nib. title is #{(a)window.title}" end def windowWillLoad puts "window will be soon loaded" end def windowDidLoad puts "window loaded" end def windowTitleForDocumentDisplayName(displayName) "Hello World" end

MacBacon problem
by stephen horne 03 Dec '12

03 Dec '12

I'm trying to get started with tdd and MacRuby, but I've hit a stumbling block immediately with macbacon. I suspect it's something to do with rvm, but I'm not sure. When I run macbacon like this: $macbacon my_class_test.rb I get the following error backtrace: /Users/fatboy/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': /Users/fatboy/.rvm/gems/ruby-1.9.3-p125/gems/mac_bacon-1.3/lib/mac_bacon.rb:212: syntax error, unexpected tLABEL (SyntaxError) ...eForKeyPath(key_path, ofObject:object, change:_, context:__) ... ^ /Users/fatboy/.rvm/gems/ruby-1.9.3-p125/gems/mac_bacon-1.3/lib/mac_bacon.rb:337: class definition in method body /Users/fatboy/.rvm/gems/ruby-1.9.3-p125/gems/mac_bacon-1.3/lib/mac_bacon.rb:429: syntax error, unexpected keyword_end, expecting $end from /Users/fatboy/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from /Users/fatboy/.rvm/gems/ruby-1.9.3-p125/gems/mac_bacon-1.3/bin/macbacon:110:in `<top (required)>' from /Users/fatboy/.rvm/gems/ruby-1.9.3-p125/bin/macbacon:19:in `load' from /Users/fatboy/.rvm/gems/ruby-1.9.3-p125/bin/macbacon:19:in `<main>' Can anyone see what's wrong with my setup?

gem install globalchat https://rubygems.org/gems/globalchat Should work on Mac, Windows and Linux. On Linux you need a lot of dependencies but it will work. sudo aptitude install build-essential bison openssl libreadline5 libreadline-dev curl git-core zlib1g zlib1g-dev libssl-dev vim libsqlite3-0 libsqlite3-dev sqlite3 libreadline5-dev libreadline6-dev libxml2-dev git-core subversion autoconf xorg-dev libgl1-mesa-dev libglu1-mesa-dev cmake libqt4-dev If you're really crazy to try it And I was able to achieve a degree of success in Windows with Ruby OCRA bundler, the EXE can be found here: https://github.com/downloads/jsilverMDX/GlobalChat2/GlobalChat2-Windows.zip Sources are in the main GlobalChat2 repository on GitHub Domo jsilver

A QtRuby Version of The GC2 Client has Been Created
by J Silver 23 Nov '12

23 Nov '12

http://cl.ly/image/2w0P1X3H1v3T http://cl.ly/image/3Q3j260q1s1F Want to report success using QtRuby library with the qtbindings gem. Internally, Able to use Signals and Slots through the advanced techniques described around the web. Now have a working version of the chat available in the GlobalChat2 repository. https://github.com/jsilverMDX/GlobalChat2/tree/master/gc2-qtruby It runs on 1.8.7 and 1.9.3. It lacks many of the features of the advanced MacRuby client coming soon to App Store. It uses QtDesigner for the GUI files with the UI loader and should run natively on Mac, Windows and Linux. However, one thing. The MacRuby client is DAYS faster getting a big log back from the server than QtRuby, and the signal is obviously not to blame. This happens on both 1.9 and 1.8.7. Any ideas? HAPPY TURKY DAY! jsilver

Using Virtus or SmartProperty as outlets?
by Carolyn Ann Grant 22 Nov '12

22 Nov '12

I've done a bit of Googling, but couldn't find anything on this. I'd like to use something like SmartProperties (for lightweight situations) or Virtus (when I absolutely must have industrial-strength validations, etc) as outlets. My experiments, such as they are, aren't helping me any! What, if anything, am I doing wrong? My experiments are basically: require 'virtue' class TestClass attribute :test_attr, String end And then I try to "wire" up a text field from IB to the attribute; the result? Nothing happens. Basically, I need to make sure that when I ask for an integer, I get an integer. And when I want a string - I can reject anything but strings. But sometimes I'd like the "defaults" capability of Virtus & SmartProperty, and I'd definitely like the industrial-strength validations of Virtus when I'm working against the database. In MacRuby terms, am I addressing the right problem!? Did I miss something in my Googling? Thanks in advance! Carolyn

Cannot compile RJB using MacRuby nightly
by Eduardo G. Melguizo 20 Nov '12

20 Nov '12

Hi all, I installed macruby-nightly from RVM, installed a few gems such as Nokogiri and modified a test XCode project scheme accordingly to get the gems to be known by XCode and it was a success! Now, one additional gem I would like to use have a dependency on RJB, as it contains a jar file. But the installation of RJB fails. It has a dependency on dl.h, a header that I have seen in MRI 1.9.2 and 1.9.3 inside a 1.9.1 folder (/Users/tnarik/.rvm/rubies/ruby-1.9.3-p125/include/ruby-1.9.1/ruby/dl.h), but not in MacRuby. I'm trying to identify it this file is needed at all of it it's part of some future MacRuby release. Or if what I'm trying to do here it's impossible and I should find an alternative without RJB dependencies. Any thoughts? Regards, Eduardo

Malloc and EXC_BAD_ACCESS error for this loop
by F. Timur Senguen 16 Nov '12

16 Nov '12

Hi everyone, I am trying to write a simple batch Excel extractor: I have an array of file names that I created a .each loop for. In the loop (under Exception handling) I open that file, add the name of the file to another spreadsheet (which I created earlier), then move on to the next file. This works great for the first 3 files, but after that I get malloc errors and eventually the app crashes with an EXC_BAD_ACCESS error in the Garbage Collection Work Queue. Code: require 'rubygems' require 'write_xlsx' require 'roo' class SimpleExcelExtractor attr_accessor :input_path, :output_path, :input_button, :output_button attr_accessor :quit_button, :go_button, :sheet_text, :column_text, :row_text GUI Stuff ... ... ... def run_func(input, filelist, sheet, column, row, output) row = col = 0 wb = WriteXLSX.new(output) worksheet = wb.add_worksheet p filelist filelist.each do |f| begin input_file = Excelx.new(input + "/" + f) p "Opened file: " + f worksheet.write(row, col, f) p "Wrote it up" row += 1 p "Went ahead" input_file rescue Exception => e p e end end p "Saving now" wb.write p "Saved" end def quit_func(sender) end end Debug output: *["test 2.xlsx", "test.xlsx", "test2 2.xlsx", "test2.xlsx", "test3 2.xlsx", "test3.xlsx", "test4 2.xlsx", "test4.xlsx"]* *"Opened file: test 2.xlsx"* *"Wrote it up"* *"Went ahead"* *"Opened file: test.xlsx"* *"Wrote it up"* *"Went ahead"* *"Opened file: test2 2.xlsx"* *"Wrote it up"* *"Went ahead"* *"Opened file: test2.xlsx"* *SimpleExcelExtractor(57679,0x1082f6000) malloc: *** free() called on collectable block with 0x401234b20 with refcount 0 (ignored)* *"Wrote it up"* *"Went ahead"* *SimpleExcelExtractor(57679,0x1082f6000) malloc: *** free() called on collectable block with 0x4016622e0 with refcount 0 (ignored)* *SimpleExcelExtractor(57679,0x1082f6000) malloc: *** free() called on collectable block with 0x40127b640 with refcount 0 (ignored)* *SimpleExcelExtractor(57679,0x1082f6000) malloc: *** free() called on collectable block with 0x40138b7a0 with refcount 0 (ignored)* *SimpleExcelExtractor(57679,0x1082f6000) malloc: *** free() called on collectable block with 0x40154cd40 with refcount 0 (ignored)* *SimpleExcelExtractor(57679,0x1082f6000) malloc: *** free() called on collectable block with 0x40136d4c0 with refcount 0 (ignored)* *SimpleExcelExtractor(57679,0x1082f6000) malloc: *** free() called on collectable block with 0x4016d2620 with refcount 0 (ignored)* *(lldb) * Then in the Debug window it has the following in the Garbage Collector Work Queue: #include <xml_node_set.h> #include <libxml/xpathInternals.h> static ID decorate ; static int dealloc_namespace(xmlNsPtr ns) { if (ns->href) <----Thread 12: EXC_BAD_ACCESS (code=1, address = 0x22) xmlFree((xmlChar *)ns->href); if (ns->prefix) xmlFree((xmlChar *)ns->prefix); xmlFree(ns); return ST_CONTINUE; } -- F.

New Version of GlobalChat2 Pro on App Store
by J Silver 14 Nov '12

14 Nov '12

GlobalChat https://itunes.apple.com/us/app/globalchat-2-pro/id566614902?ls=1&mt=12 https://itunes.apple.com/us/app/globalchat-server/id566163288?ls=1&mt=12 Written in 100% MacRuby! Source code: https://github.com/jsilverMDX/GlobalChat2 Bonus: RubyMotion version Definitely planned and in the works: Android Ruboto version Not yet planned or in the works: Windows, Linux Reporting in on IronRuby, it feels like a huge dead end. Takes ages to get anywhere and there's no toolchain support in OS X, though it builds under Mono. It's incredibly frusterating because it seems that the language they built is actually 99% of what it needs to be to be a great Ruby next to MacRuby. But there doesn't seem to be an interest (?) even by Xamarin, Mono developer, so I've given up on it. Shoes may be used to make the Windows or Linux versions. If anyone knows any other cross platform Ruby solutions, please let me know! Thanks and MINASWAN ! Jonathan Silverman

Core Dump When Importing 3rd Party gems
by Templeton Jason 14 Nov '12

14 Nov '12

I've been having some problems importing 3rd party gems. Basically, this is what happens #!/usr/local/bin/macruby framework 'Foundation' framework 'ScriptingBridge' framework 'cocoa' puts "Hola" require "rubygems" puts "Imported rubygems" require "mechanize" puts "Imported mechanize..." I will get a Segmentation Fault when I import mechanize, this also happens if I replace the import of mechanize with 'nokogiri'. I can import sqlite3, but I just can't refer to SQLite3::Database.new, otherwise, I get another Segmentation Fault In other words, I will see from the above code: Hola Imported rubygems Segmentation fault This is my setup [ jtempleton macruby_client(master) 01:11 ] macruby -v MacRuby 0.12 (ruby 1.9.2) [universal-darwin10.0, x86_64] Mac Version 10.6.8, 2Ghz Core i7, 8GB RAM $ macgem list ** LOCAL GEMS ** ----- mechanize (2.5.1) nokogiri (1.5.2, 1.5.0, 1.4.3.1) sqlite3 (1.3.5) sqlite3-ruby (1.3.3) ------ I was also having the same thing occur on macRuby 0.11 Any suggestions would be greatly appreciated. Thank you!!! Jason
