> Hi Russell, > > Sorry for the late response. no worries... :) > OpenDirectory.framework ships with BridgeSupport annotations, so doing "framework 'OpenDirectory'" should merge all symbols into MacRuby. If some are missing, it's likely a bug in the BridgeSupport generator, that should be reported via http://bugreport.apple.com. cool - shall do... I wasn't doing that until I had some evidence it wasn't just me missing something... > Fortunately, we are working on a new BridgeSupport generator which might already fix this issue, but it's not ready yet for prime time. In the meantime I recommend to wrap the symbols/APIs you need inside an Objective-C class and call it from MacRuby. I've ended up just running the relevant OpenDirectory headers through perl to generate an opendirectory/constants.rb that I pull into the other stuff I'm doing - pretty straightforward once I figured out where the strings I was after lived... in case anyone finds it useful, here's gen-constants.sh which pulls in both the enum constants and the extern NSString "constants" into a single ruby file... #!/bin/sh target_dir=$(dirname "$0")/../lib/opendirectory target_file=${target_dir}/constants.rb cat <<HEADER > $target_file module OpenDirectory module Constants HEADER # enum constants curl 'http://www.opensource.apple.com/source/OpenDirectory/OpenDirectory-57/CFOpe…' | \ perl -ne 'next unless /^\s*kOD([A-Za-z]+)\s*=\s*(0x[0-9a-fA-F]+)/; print qq( $1 = $2\n)' >> $target_file # string "constants" curl 'http://www.opensource.apple.com/source/OpenDirectory/OpenDirectory-57/CFOpe…' | \ perl -ne 'next unless /^\s*CFStringRef\s+kOD([[:alpha:]]+)\s*=\s*CFSTR$(".*?")$/; print qq( $1 = $2\n)' >> $target_file cat <<FOOTER >> $target_file end end FOOTER

how to access OpenDirectory C constants from MacRuby?
by russell muetzelfeldt 10 Apr '10

10 Apr '10

Hi All, I'm trying to use MacRuby (0.5) to poke at OpenDirectory, but can't figure out how to get the ruby environment to see constants defined in the CFOpenDirectory subframework of the OpenDirectory framework. http://gist.github.com/358599 is a simple case of what I can't work out. Constants like ODSessionProxyAddress are visible when I'm opening a connection to a remote OD server, but the kSomeConstant ones aren't available under their obj-c or capitalised-K versions (as vaguely implied in http://www.macruby.org/recipes/embed-a-custom-font.html) The bridgesupport files in OpenDirectory.framework also don't contain entries for these constants. Is there some way of getting access to these constants, or do I need to find and use their literal values instead? cheers Russell

[MacRuby] #201: rb_objc_define_kvo_setter does not handle the case where the user might override the regular Ruby writer method.

#201: rb_objc_define_kvo_setter does not handle the case where the user might override the regular Ruby writer method. -------------------------------------+-------------------------------------- Reporter: eloy.de.enige@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- In my opinion, the setter created by rb_objc_define_kvo_setter should check if the user might have overrided the regular Ruby writer method and call it. Consider: {{{ class Foo attr_accessor :bar def bar=(value) @bar = 'bar' # super # depending on the impl. end end f = Foo.new f.bar = "foo" f.bar # => "bar" f.setBar("foo") f.bar # => "foo" }}} The user will expect the value to always be "bar" as defined in the #bar= impl. -- Ticket URL: <http://www.macruby.org/trac/ticket/201> MacRuby <http://macruby.org/>

[MacRuby] #645: Segmentation Fault using File::sysseek

#645: Segmentation Fault using File::sysseek ----------------------------+----------------------------------------------- Reporter: foranje@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: ----------------------------+----------------------------------------------- Using the sysseek method of a file always seems to result into a Segmentation fault using MacRuby. Using the same code with regular Ruby works fine. '''test.rb''' {{{ file = File.new("test.txt") file.sysseek(2, IO::SEEK_SET) print file.sysread(5) file.close }}} '''test.txt''' {{{ blaatblaatblaatblaatblaat }}} '''Result''' when executing the file using MacRuby: {{{ Segmentation fault }}} If I comment out the sysseek line, it gives no error. So the sysseek seems to be the issue. -- Ticket URL: <http://www.macruby.org/trac/ticket/645> MacRuby <http://macruby.org/>
