encoding mismatch ?
by Yvon Thoraval 11 Mar '10

11 Mar '10

I have to read an UTF-8 encoded file with accentuated chars. if i do : #! /usr/local/bin/macruby # encoding: utf-8 SIGNATURES_FILE = "/Users/yt/dev/Signature/signatures.txt" open(SIGNATURES_FILE) do |file| file.each do |line| puts line end end i get the correct characters on the Terminal, ie. : ... -- « Pour ceux qui vont chercher midi à quatorze heures, la minute de vérité risque de se faire longtemps attendre. » (Pierre Dac) however when doing (with or without the .force_encoding("UTF-8" and , "r:UTF-8") : t = "".force_encoding("UTF-8") open(SIGNATURES_FILE, "r:UTF-8") do |file| file.each do |line| t += line.force_encoding("UTF-8") end end puts t i get wrong chars : ... -- Â« Pour ceux qui vont chercher midi Ã quatorze heures, la minute de vÃ©ritÃ© risque de se faire longtemps attendre. Â» (Pierre Dac) the only difference is that i make use of a String t = "" what did i missunderstood ?

RE2: a principled approach to regular expression matching - Google Open Source Blog

Fascinating. Wonder if Ruby might benefit from this... http://google-opensource.blogspot.com/2010/03/re2-principled-approach-to-re… Today, we released RE2 as an open source project. It's a mostly drop-in replacement for PCRE's C++ bindings and is available under a BSD-style license. See the RE2 project page for details.

[MacRuby] #624: assigning a layout_view to a layout_view in a block and then assigning it to a window.view: fails

#624: assigning a layout_view to a layout_view in a block and then assigning it to a window.view: fails ----------------------------------------+----------------------------------- Reporter: pontus.stromdahl@… | Owner: lsansonetti@… Type: defect | Status: new Priority: minor | Milestone: MacRuby 0.6 Component: MacRuby | Keywords: hotcocoa layout_view setFrame superclass ----------------------------------------+----------------------------------- I built MacRuby from the trunk and started a hotcocoa app that I've been working. I got this little thing: /Library/Frameworks/MacRuby.framework/Versions/0.6/usr/lib/ruby/Gems/1.9.0/gems/hotcocoa-0.5.1.1/lib/hotcocoa/layout_view.rb:321:in `setFrame:': super: no superclass method `setFrame' for #<HotCocoa::LayoutView:0x2005d32c0> (NoMethodError) So far I've tracked the problem to the following: if I do this, (assume that I have the code from the start method in the hotcocoa tutorial) win.view = layout_view do |view1| view1 << layout_view end then I get the error above. (see first trace below) if I do this instead win.view = layout_view view2 = layout_view win.view << view2 everything is well, except for some NSLock thing (see second trace below). This does not happen with 0.5. I used both the hotcocoa 0.5.1 gem as well as the current master from dj2.

MacRuby 0.5 vs. CG Bitmap Context
by Scott Thompson 07 Mar '10

07 Mar '10

I'm using MacRuby to work with CoreGraphics and having some trouble with pointers. My first attempt was to create the data for a bitmap context using NSMutableData: bitmap_data = NSMutableData.alloc.initWithLength(image_data_size) bitmap_context = CGBitmapContextCreate( bitmap_data.mutableBytes(), image_width, image_height, 8, image_width, gray_color_space, KCGImageAlphaNone) If I do this, I get an error that "expected instance of Pointer of type 'v', got 'C' (TypeError)" I gather from this that CGBitmapContextCreate was expecting a (void *) and got a (UInt8 *). In C I would just type the difference away, but Ruby doesn't like ti. I tried something like: bitmap_data_ptr = Pointer.new_of_type('v') bitmap_data_ptr.assign(bitmap_data.mutableBytes()) This didn't work very well either. I get an error that the system can't do a "sizeof" of an unsized type (presumably void *) I also tried doing similar using CFDataRef (not much difference really). It looked like: bitmap_data = CFDataCreateMutable(nil, image_data_size) CFDataSetLength(bitmap_data, image_data_size) bitmap_data_ptr = CFDataGetMutableBytePtr(bitmap_data) bitmap_context = CGBitmapContextCreate( CFDataGetMutableBytePtr(bitmap_data), image_width, image_height, 8, image_width, gray_color_space, KCGImageAlphaNone) In this case, I get an error that "expected instance of Pointer, got '""' (NSMutableString) (TypeError) Evidently MacRuby sees the return value of CFDataGetMutableBytePtr as being a string, subsequently typecasts it as such, and goes on. Is there anything I can do to typecast the pointers to a type that MacRuby will accept? Scott

unit testing and mocks
by Jason Coffin 01 Mar '10

01 Mar '10

Greetings, I was wondering what our choices are for unit test/mocking frameworks for MacRuby 0.5. It seems Test::Unit and Bacon work. How about Rspec? I wasn't able to get Shoulda working. How about mocking frameworks? Is Mocha, RR or any of the other mock frameworks working? Thanks in advance! ~ Jason
