[MacRuby] #174: Allow embedding of arbitrary versions of MacRuby

#174: Allow embedding of arbitrary versions of MacRuby --------------------------------+------------------------------------------- Reporter: self@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: --------------------------------+------------------------------------------- However the new embedding approach for MacRuby should work it should not be dependent upon the version of MacRuby that is installed on the system (ideally it should not even be dependent upon there *being* a version of MacRuby installed). The primary use case is anticipating needing 0.4, 0.5, or 1.0 installed for apps that I am running that depend upon MacRuby (e.g. LimeChat when it moves across) and wanting to deploy other versions (e.g. trunk) in my own application. I'm also not keen on the removal of the build_as_embeddable option and a new dependency upon Xcode. I would rather this problem were solved by keeping the build_as_embeddable rask task and having that task patch the dylibs and and embed them into MR itself (rather than into my application). The way things are going MacRuby is forcing its dependencies into my project. I want to treat it just like any other framework I link to. -- Ticket URL: <http://www.macruby.org/trac/ticket/174> MacRuby <http://macruby.org/>

MacRuby talk at the San Francisco Ruby MeetUp, 12/11
by Rich Morin 06 Dec '08

06 Dec '08

FYI... Laurent Sansonetti of Apple will reprise his RubyConf 2008 talk on MacRuby, a version of Ruby 1.9 that makes convenient and efficient use of Mac OS X core technologies such as the Objective-C common runtime and garbage collector, and the CoreFoundation framework. -- http://www.meetup.com/sfruby/calendar/8841115/ -r P.S. I'm collecting names of folks who would like to attend a Bay Area MacRuby hackfest (aimed at app developers). Drop me a line if you're interested... -- 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, and web development

Limelight - possible HC mashup candidate
by Rich Morin 05 Dec '08

05 Dec '08

I recently ran across Limelight, a JRuby-based toolkit for the creation of portable, GUI-based applications. Rather than try to explain it, I'll just point you to this video: http://limelight.8thlight.com/screencasts/CalculatorProductIn10min.mov I think it might be pretty neat to do that sort of thing in HotCocoa. Dunno anything about how hard that would be, but I thought it might be worth bringing up the idea. See http://limelight.8thlight.com/ for more information. -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, and web development

printing
by John Shea 04 Dec '08

04 Dec '08

Hello all, has anyone done any printing in MacRuby? I can get it to print ok - if I select the page range, otherwise the print routine wants to print thousands (or more - i got scared and stopped it) pages. The rectForPage and the drawRect get called those thousands of times - even though the range should be 1 page. I suspect that the issue is in the knowsRangePage - it is passed a pointer. I de reference the pointer with range = range_pointer[0] (which does give me a range) and then set values with range.location = etc, etc (rather than range_pointer->location = 1 , in Objective C) My suspicion is that although i set the range length and location that in fact it is not changing the original pointer appropriately, but perhaps inappropriately ;-) with a very large number (a memory address perhaps?). Anyone else had this issue? cheers and thanks, John

HotCocoa Part I
by Richard Kilmer 03 Dec '08

03 Dec '08

All, As the main author of HotCocoa let me chime in on what I see its main purpose is. In a nutshell here is my 5 second primary definition: "HotCocoa is an idiomatic Ruby API that simplifies the configuration and wiring together of complex ObjC/Cocoa classes." I realize this will not be all things to all people, and that some may not see the much value in this. I do, and I think that HotCocoa should NOT try and be all things to all people. Let me even get more specific. I don't think that HotCocoa should strive to contain simplifications for all frameworks in Cocoa. If core audio needs to be simplified though a wonderful Ruby API then it should be done with a wonderful Ruby API, but that is not HotCocoa, its a core audio MacRuby library. Something that uses HotCocoa could also use that wonderfully simplified core audio library. To try and say every simplified use of ObjC frameworks is included in HotCocoa creates a truly unwieldy beast. In ObjC/Cocoa here are the common patterns I see that can be simplified with HotCocoa: * Instance configuration * Delegation * KVO * Object wiring/containment/etc * Data sources * App building I will follow up with an email that explains these in more detail and provides examples. Best, Rich

sub classing with hot cocoa
by John Shea 03 Dec '08

03 Dec '08

Hi folks, I am sure there is an easy answer to this question, but I have not figured it out after some experimenting (nor can I find an example in the examples) What do I do if i want to subclass (say) an NSView ? And yet still employ that subclass with all the rest of the hot cocoa magic? (so without using nib/xibs) I would do this to overwrite the drawRect callback for NSView for example - perhaps to do some animation. Thanks in advance, John
