Starting a New Project tutorial
by Frisco Del Rosario 16 Mar '09

16 Mar '09

I'm following the steps to Starting a New Project at http://www.macruby.org/trac/wiki/MacRubyTutorial, which says: First, let's instantiate our class. In the Library pane, drag-and-drop an NSObject item to the main window. Then, make sure you selected it, and open the inspector pane (click on Window, then Document Info). In the Object Identity tab, select MyController as the object class. But after dragging and dropping an NSObject into the MainMenu.nib window, Document Info shows nothing in the Object ID panel.

OT: seeking advice on GIT client for OSX
by Sophie (itsme213) 14 Mar '09

14 Mar '09

Google was somewhat inconclusive, so I'm seeking recommendations here. Apologies if inappropriate, but I'd guess folks here would know. What GIT OSX client would you recommend, comparable to Cornerstone (osx svn client) or Tortoise-SVN (windows SVN client) ? Thanks!

[MacRuby] #154: Odd behavior with NSTableView
by MacRuby 12 Mar '09

#154: Odd behavior with NSTableView -------------------------------------+-------------------------------------- Reporter: parzival(a)mindspring.com | Owner: lsansonetti(a)apple.com Type: defect | Status: new Priority: minor | Milestone: Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- I'm trying to learn some Mac programming via MacRuby & Xcode, so I built the project in the tutorial here: http://developer.apple.com/mac/articles/scriptingautomation/cocoaappswithma… (It's a good tutorial; perhaps it should be added to the examples unless that's already been done.) Just playing around I tried extending it by adding a 'phone number' field. That worked fine until I attempted to do some formatting on the input. If you're unfamiliar with the project, it builds a simpls NSTableView with a few fields, a Controller class, and then a Friend class to store the data (first name, last name, etc). Aside from adding a few lines to the Controller class, I added a setter function to the Friend class. Here's the setter function (comments stripped): def setphone_no (p_no) @phone_no=p_no.gsub(/[^\d]/,'') if @phone_no.length > 10 # || p_no[0] == '+' @phone_no = '+' << @phone_no end end This mostly works, except in the following case. If a string is entered into a field that is only digits, and longer than the limit (10), all that gets displayed in the table is the "+". The field works okay if you change the number after that. In fact, the number seems to be stored okay; it's only being displayed properly that is the problem. Adding the second test condition has no effect. However, strings which fail the first test and pass the second are okay. It's only the ones that are 'too long' that end up missing. Strings that work: The default string that gets passed from the Controller class : "0123456789012" (but this does NOT work if typed in) "+012345" (any string with a leading + (regardless of length if the second condition is turned on)) "01234567890 12" (any long string with a non-numeric in it) "0123456789" (any string of 10 or fewer digits) Other things tried: Using either attr_reader or a custom getter makes no difference. I tried using a different attached marker ('INT' instead of '+') - whatever the marker is is all that gets displayed for 'bad' strings. No difference using ' vs. " or + vs. << to add the marker. Changing the length limit affects the length of strings that will not get displayed, but otherwise shows the same problem. Changing the test condition order has no effect. Looking at the console output using 'debugging' puts lines, the Friend object always shows the entered value correctly (e.g. when updating the table after another entry is changed). The class (when setting or getting) shows up as NSMutableString. This problem doesn't seem to show up when doing this without a GUI. I pulled out what just the Friend class and made a simplified Controller class, and it tested fine in macirb. Project is attached. -- Ticket URL: <http://www.macruby.org/trac/ticket/154> MacRuby <http://macruby.org/>

[ANN] MacRuby 0.4
by Laurent Sansonetti 10 Mar '09

10 Mar '09

Hi, After several months of development and some slight delays, MacRuby 0.4 is now available. Get it here while it's still hot! MacRuby is a version of Ruby 1.9, ported to run directly on top of Mac OS X core technologies such as the Objective-C common runtime and garbage collector, and the CoreFoundation framework. While still a work in progress, it is the goal of MacRuby to enable the creation of full-fledged Mac OS X applications which do not sacrifice performance in order to enjoy the benefits of using Ruby. You can learn more about MacRuby, and download a binary installer, from the website: http://ruby.macosforge.org Or about this release more specifically, on our blog: http://www.macruby.org/post/macruby-04 Enjoy, Laurent

I've been successfully building the MacRuby framework as a 32bit PPC/i386 UB, from trunk, with following command: RC_ARCHS="ppc i386" rake macruby For some reason, the order in which the archs are specified matters. I am not sure how well it actually runs, as I don't have any reports from PPC users for my app, and it doesn't work in Rosetta. 2009/3/9 Rich Morin <rdm(a)cfcl.com>: > On Mon, Mar 9, 2009 at 2:52 PM, Laurent Sansonetti >> You can learn more about MacRuby, and download a binary installer, >> from the website: >> >> http://ruby.macosforge.org >> >> Or about this release more specifically, on our blog: >> >> http://www.macruby.org/post/macruby-04 > > Neither the posting, the web site, nor the blog mentions the fact > that the binary installer for the new release doesn't include > support for PowerPC machines: > > $ file /usr/local/bin/macruby > /usr/local/bin/macruby: > Mach-O universal binary with 2 architectures > /usr/local/bin/macruby (for architecture i386): > Mach-O executable i386 > /usr/local/bin/macruby (for architecture x86_64): > Mach-O 64-bit executable x86_64 > > I downloaded the sources > > $ svn co http://svn.macosforge.org/repository/ruby/MacRuby/tags/0.4 \ > MacRuby-0.4 > > and attempted to follow the build instructions on > > http://www.macruby.org/trac/wiki/InstallingMacRuby > > $ cd MacRuby > MacRuby: No such file or directory. > > Sigh. > > $ ls > MacRuby-0.4 > > $ cd MacRuby-0.4 > > $ rake > (in /Local/_Private/Homes/rdm/Private/Work/MacRuby/MacRuby-0.4) > Warning: your appear to use a PowerPC machine.

Sorry Rich, but I personally only target intel processors. I don't think MacRuby will ever officially support non-intel machines. I know that sucks but I really don't think it's worth my time.

If the gem name has a specific platform/arch then it won't be visible to alternate archicture/platforms afaik.

ruby gems just for MacRuby

Hey Guys, I worked on a JSON lib for MacRuby which uses a dynlib. I'm thinking about making it in a gem but it would only be compatible with MacRuby. I feel like we should discuss this as a group and try to come up with a standard way of dealing with this challenge. - Matt

[MacRuby] #228: Crash in my NSOutlineView data source
by MacRuby 09 Mar '09

09 Mar '09

#228: Crash in my NSOutlineView data source --------------------------------+------------------------------------------- Reporter: cyberfox@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: MacRuby 1.0 Component: MacRuby | Keywords: crash --------------------------------+------------------------------------------- Greetings, I am at a loss; I've thrown away two days trying to figure out what it might be in my code, and countless variations on the theme of 'what data will this allow?' I've tried a deep hash, recursive arrays, and now a custom Pair structure, and it always blows up at a certain point _eventually_, and not in a nice Ruby way. :) I've figured out so much, but I'm fully stymied on getting NSOutlineView working with in my app. Specifically, it appears that some data is being corrupted in memory, and when it's being referenced, it's crashing to gdb. My application is at http://github.com/cyberfox/fallout3 and is my first attempt at a MacRuby app. I don't really know Cocoa either, although I was able to figure out a lot. If you run it, and paste the following data: {{{ #1234 #4321 #1245 #2143 #5432 #3412 }}} into the TextView, then click 'Analyze', then try to open up some of the entries in the OutlineView on the right. You'll see the crash after one or two levels. I tried 0.3, I tried trunk, and then 0.4 was released, and I jumped on that. Nothing works. It's entirely possible I'm doing something wrong; I figured out how to write a NSOutlineView data source by the seat of my pants, and it's obviously possible I'm getting it wrong. But I can't imagine that I'm getting it wrong in a way that's letting me stomp on memory from Ruby... Please help me understand this; I really believe it shouldn't be crashing to GDB, even if I've really screwed up my algorithm. When debugging an earlier version (it used array pairs and .first and .last), I found it died at ruby.h:1149 which was a reference to *(Class *)obj == (Class)rb_cFixnum and it was blowing up because obj was 0xffffffff, obviously bad. I believe that something is getting stomped on; and my program is showing it consistently. It is likely my fault, but it shouldn't be _possible_... Please try it and let me know what is going on... -- Morgan Schweers -- Ticket URL: <http://www.macruby.org/trac/ticket/228> MacRuby <http://macruby.org/>
