Re: [MacRuby-devel] status and prospects of HotCocoa?
by Matt Aimonetti 11 Jun '10

Unless some people really embrace the project, fix the various issues and add a proper test suite, I don't know if HotCocoa will survive too long. However, it looks like enough people are interested in doing something with HotCocoa, I would suggest to fork the project (it's on github) and set a team of people to work on it. - Matt On Thu, Jun 10, 2010 at 3:41 PM, Rich Morin <rdm(a)cfcl.com> wrote: > I folded some information from Dan and Gary into a wiki page: > > https://www.macruby.org/trac/wiki/HotCocoaResources > > and tweaked the main page a bit: > > https://www.macruby.org/trac/wiki/HotCocoa > > Contributions and corrections are solicited... > > -r > -- > http://www.cfcl.com/rdm Rich Morin > http://www.cfcl.com/rdm/resume rdm(a)cfcl.com > http://www.cfcl.com/rdm/weblog +1 650-873-7841 > > Technical editing and writing, programming, system design > _______________________________________________ > MacRuby-devel mailing list > MacRuby-devel(a)lists.macosforge.org > http://lists.macosforge.org/mailman/listinfo.cgi/macruby-devel >

[MacRuby] #269: Calling a method on a pointer passed to a KVC validation method fails

#269: Calling a method on a pointer passed to a KVC validation method fails --------------------------------+------------------------------------------- Reporter: mikael@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: kvc pointer crash --------------------------------+------------------------------------------- If I define a -validate<Key>:error: method in the class used as an NSArrayController's class, any method call on any parameter causes a crash. == Steps to reproduce: == Create a new MacRuby project. Place a table view and a button in the main window. Instantiate a new NSArrayController. Set the class of the array controller to SomeModel, with the key someKey. Bind the table view's single column's value to the array controller's arrangedObject.someKey key path, and check Validates Immediately. Set the button's target to be the array controller, action add:. Create a new Ruby file in the project. Here's the code: {{{ #encoding: utf-8 class SomeModel attr_accessor :someKey def validateSomeKey someKeyPointer, error: errorPointer NSLog "Validating someKey." someKeyPointer.nil? # This is where the program crashes. return true end end }}} Launch the application, add a new row, try to change its someKey. When you press enter, it crashes. Attached is the backtrace I get from GDB. -- Ticket URL: <http://www.macruby.org/trac/ticket/269> MacRuby <http://macruby.org/>

status and prospects of HotCocoa?
by Rich Morin 10 Jun '10

10 Jun '10

I'm curious about the status of HotCocoa. Although it seems like a very cool piece of technology, the activity level and documentation status seem pretty minimal. For example: * http://www.macruby.org/trac/wiki/HotCocoaStatus shows about thirty "partial" mappings; the rest are "unknown". * http://www.macruby.org/trac/wiki/HotCocoaTutorial just says "TODO". * "MacRuby: The Definitive Guide" doesn't mention HotCocoa in the Table of Contents. If some folks here are using HotCocoa, I'd love to see some examples, howtos, etc! -r -- http://www.cfcl.com/rdm Rich Morin http://www.cfcl.com/rdm/resume rdm(a)cfcl.com http://www.cfcl.com/rdm/weblog +1 650-873-7841 Technical editing and writing, programming, system design

YAML - taquri? warning
by macruby＠djc.net 10 Jun '10

10 Jun '10

Under MacRuby 0.6, dumping out a large Hash into a YAML file generates many warning lines of: unknown: warning: instance variable @taguri not initialized A brief web search sees this popping up in ruby 1.8.3, but subsequently fixed (at least 1.8.7 does not emit these msgs) Are there known issues with YAML dumps, especially on large Hashes (under MR, native NSDictionaries passed back from a framework)? -Daniel

WebScripting protocol
by Michael Jackson 10 Jun '10

10 Jun '10

Hi, I'm trying to create an object that conforms to the WebScripting protocol, but the only method that is working is invokeUndefinedMethodFromWebScript:withArguments:. Here's a sample of my class so far. The puts statements are just there so I can see what is actually being called. For reference, the WebScripting protocol is defined here: http://developer.apple.com/mac/library/documentation/Cocoa/Reference/WebKit… class HelloScriptObject def self.isKeyExcludedFromWebScript(key) puts key.inspect end def self.webScriptNameForKey(key) puts key.inspect end def self.isSelectorExcludedFromWebScript(sel) puts sel.inspect end def self.webScriptNameForSelector(sel) puts sel.inspect end def invokeUndefinedMethodFromWebScript(name, withArguments:args) puts name puts args.inspect end def sayHi puts 'hi' end end The sayHi method is the one that I'm calling via JavaScript, but every time it just defaults to using invokeUndefinedMethodFromWebScript:withArguments: instead of using self.isSelectorExcludedFromWebScript: to first check if the selector is valid or not. Is support for this implemented yet (in 0.6)? If so, what am I missing? Thanks, Michael -- Michael Jackson http://mjijackson.com @mjijackson

Has anyone used Apple's ImageAndTextCell in a MacRuby example? ImageAndTextCell is included in the "DragNDropOutlineView" sample code. Thanks, Bob Rice

REXML
by Robert Rice 09 Jun '10

09 Jun '10

Note to REXML users. I suspect that there is a bug in the each_element method of REXML. In the each_element loop I would get intermittent errors where the index was not a REXML element or I would get a Bad Instruction crash with no traceback. My system became stable after replacing calls to each_element with elements.each. Bob Rice

Ruby and JSCocoa — A bridge from Ruby to JavascriptCore too far?
by Ernest N. Prabhakar, Ph.D. 09 Jun '10

09 Jun '10

Hi all, Okay, this is probably a completely insane idea brought on my WWDC/toddler-induced sleep deprivation, but... Given all the hoopla around node.js lately, I've been playing around with JSCocoa to see what can be don with JavaScript on the Mac: http://inexdo.com/JSCocoa Alas, my ObjC skills have atrophied (or maybe just spoiled by Ruby), so I've looked with envy at various Ruby-in-JavaScript solutions: cowboyd's therubyrhino at master - GitHub therubyracer jbarnette's johnson at master - GitHub The simplest of these is Rhino, since it already "boxes" up JavaScript inside the Java object model, which bridges trivially to JRuby. If I squint just right and don't think too hard, it seems like I should be able to do the same thing with JSCocoa from MacRuby. That is, use JSCocoa as a "JavaScript API to real objects" translator, then MacRuby to access those objects from there. The tricky part is that JSCocoa still passes around a bunch of C structs (JS Data types). But presumably Bridge Support can take care of (most) of that for me? Or am I overlooking something profound? -- Ernie P.
