[MacRuby] #308: "too short multibyte code string" when using Pathname

#308: "too short multibyte code string" when using Pathname -------------------------------+-------------------------------------------- Reporter: tjw@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: -------------------------------+-------------------------------------------- Possibly related, but simpler case of https://www.macruby.org/trac/ticket/303 See the attached script, which hits a regex parse error when run. Digging around, it looks like this might start from lib/pathname.rb in #initialize: if /\0/ =~ @path raise ArgumentError, "pathname contains \\0: #{(a)path.inspect}" end The /\0/ fails to parse and a RegexpError error is thrown. -- Ticket URL: <http://www.macruby.org/trac/ticket/308> MacRuby <http://macruby.org/>

[MacRuby] #529: Using a Proc as a ‘callback function’

#529: Using a Proc as a ‘callback function’ -------------------------------------+-------------------------------------- Reporter: eloy.de.enige@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- Some Cocoa methods, or C functions, take pointers to functions which can be used as callbacks. For instance, FSEventStreamCreate: http://bit.ly/8p70Yw. RubyCocoa, in conjunction with BridgeSupport, supported this by allowing the user to give a proc that would be used as the callback. MacRuby should support this too. Here's a spec example: {{{ describe "BridgeSupport" do it "bridges a proc to be used where a pointer to a callback function is required" do array = [5, 3, 2, 4, 1] proc = Proc.new do |x, y, context_pointer| context = context_pointer[0].chr + context_pointer[1].chr + context_pointer[2].chr x <=> y if context == 'foo' end array.sortUsingFunction(proc, context: 'bar') array.should == [5, 3, 2, 4, 1] array.sortUsingFunction(proc, context: 'foo') array.should == [1, 2, 3, 4, 5] end end }}} Don't know if this is feasible, but it would be great if the arguments given to the proc, like the context argument, were no Pointer objects, but the object they actually point to: {{{ describe "BridgeSupport" do it "bridges a proc to be used where a pointer to a callback function is required" do array = [5, 3, 2, 4, 1] proc = Proc.new do |x, y, context| x <=> y if context == 'foo' end array.sortUsingFunction(proc, context: 'bar') array.should == [5, 3, 2, 4, 1] array.sortUsingFunction(proc, context: 'foo') array.should == [1, 2, 3, 4, 5] end end }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/529> MacRuby <http://macruby.org/>

Will FFI make it into macruby?
by robert gleeson 18 Mar '10

18 Mar '10

Hi -- I read on a previous post in the mailing list that some/basic support for C extensions will be implemented for 0.6 .. Great work! And that brought me onto my question, will FFI be distributed with MacRuby whenever it becomes a little more stable? I think it'd be a great addition if a fully-featured FFI library was apart of MacRuby. Thanks, Rob

Hi group: UTF-8 default is working again in 3/17 build but I have new problems with strings: Given: def reportDate return nil if @calendar.nil? desc = @calendar.dateValue.description desc.slice(0..3) + desc.slice(5..6) + desc.slice(8..9) end puts "rptdate #{reportDate}" I get: 2010-03-17 23:03:32.320 MacRuby 0.5[1594:a0f] undefined method `slice' for #<String:0x2022a9c40> Given: def reportDate return nil if @calendar.nil? desc = @calendar.dateValue.description.to_s desc.slice(0..3) + desc.slice(5..6) + desc.slice(8..9) end puts "rptdate #{reportDate()}" I get: rptdate #<Stin:0 @calendar is linked to a Date Selector object.

After loading the latest nightly build I have a new error message generated by the following string: "#{degrees}° #{minutes}' #{seconds}\"" returns: incompatible character encodings: US-ASCII and UTF-8 Is there something I can change so that I can use special characters again? Bob Rice

Re: [MacRuby-devel] macruby and sqlite3 gem (Wladjmir)

Hi, yes i used the latest nightly build, honestly i would prefer to use sqlite3 and activerecord instead of coredata, maybe in few months that will be possible. Thanks for your commitment Wladjmir > > Hi, > > C extensions are not supported in the current stable release, 0.5. > > I suppose you are using MacRuby trunk? Support for C extensions on trunk is _very_ experimental. I was able to get the sqlite3 extension working a couple of weeks ago, but I didn't test recently. And currently trunk is a bit unstable because we just merged a big branch. I recommend to wait for the next release if you want to use C extensions, and in the meantime, to use something that does not rely on the C API (such as Objective-C frameworks like CoreData). > > Laurent > > On Mar 13, 2010, at 4:13 AM, Wladj wrote: > >> Can someone help me to get sqlite3 gem working with macruby? >> >>> macirb >> irb(main):006:0> require 'rubygems' >> => true >> irb(main):007:0> require 'sqlite3' >> => true >> irb(main):008:0> db = SQLite3::Database.new("test.db") >> Segmentation fault >> >> or suggest me a viable other way or db to have simple db function in macruby (CoreData seems to me too cumbersome) >> >> Thanks >> Wladjmir >> _______________________________________________ >> MacRuby-devel mailing list >> MacRuby-devel(a)lists.macosforge.org >> http://lists.macosforge.org/mailman/listinfo.cgi/macruby-devel

Can someone help me to get sqlite3 gem working with macruby? > macirb irb(main):006:0> require 'rubygems' => true irb(main):007:0> require 'sqlite3' => true irb(main):008:0> db = SQLite3::Database.new("test.db") Segmentation fault or suggest me a viable other way or db to have simple db function in macruby (CoreData seems to me too cumbersome) Thanks Wladjmir
