#537: Missing Time#strftime formatter: "%P" -------------------------------+-------------------------------------------- Reporter: bburky@… | Owner: lsansonetti@… Type: defect | Status: new Priority: minor | Milestone: Component: MacRuby | Keywords: -------------------------------+-------------------------------------------- I use the command line [http://sup.rubyforge.org/ sup] email program which is written in ruby. While I don't run it under MacRuby, I was checking an issue which came up on the mailing list about the "%P" formatter for strftime and tested it in MacRuby too. The "%P" should output either "am" or "pm" in lower case. Apparently most (all?) 1.8.7 rubys on OS X, don't support the "%P" formatting, which is not required. Most linux 1.8.7 rubys do support it though. MacRuby also does not support it. However it is required for 1.9. The ruby docs for Time list it for example: http://ruby-doc.org/core-1.9/classes/Time.html#M000314 Here's an example: {{{ $ macruby --version MacRuby version 0.5 (ruby 1.9.0) [universal-darwin10.0, x86_64] $ macruby -e 'puts Time.now().strftime("%l:%M%P")' 11:25P }}} That should output "11:25pm" I didn't check any of the other format strings. -- Ticket URL: <http://www.macruby.org/trac/ticket/537> MacRuby <http://macruby.org/>

Apple System Logger

I've been trying to use the asl from macruby. Accordingly I've created the necessary bridgesupport file from asl.h. I can call asl_log just fine, but the issue comes when trying to customize the message. For example, I'd like to have the output show up in Console.app. To do this I need to >> m = asl_new(ASL_TYPE_MSG) >> asl_set(m, ASL_KEY_FACILITY, "com.apple.console") >> asl_log(nil, m, ASL_LEVEL_INFO, "Shows up in console") Unfortunately there is an error on the asl_new TypeError: unrecognized runtime type `{__aslmsg=}' from /Users/cehoffman/Repos/Ruby/mp4tag/(irb):9:in `<main>' Similarly trying to use client connections fails >> asl_open($0, "com.apple.console", ASL_OPT_NO_DELAY) TypeError: unrecognized runtime type `{__aslclient=}' from /Users/cehoffman/Repos/Ruby/mp4tag/(irb):4:in `<main>' I was wondering what the next steps would be correct this since I have not encountered this error with BridgeSupport before. P.S. I found an error in gen_bridge_metadata when creating 64-bit bridgesupport files. Setting headers directly bypassed the creation of the @import_directive which prevented the script from continuing. Line 505: g.headers = @headers should be the following or similar to set @import_directive @headers.each { |header| g.add_header(header) }

[MacRuby] #599: improve reliability of LLVM build instructions

#599: improve reliability of LLVM build instructions -------------------------------------+-------------------------------------- Reporter: jordan.breeding@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- Since MacRuby currently depends on specific LLVM revisions it is a good idea to make sure the build instructions work in as many conditions as possible. Prior to Jan 27th when Xcode 3.2.2 got put into beta this was fairly easy. You could just trim things like /usr/local and /Developer/usr/bin from your path long enough to build LLVM with these instructions: {{{ ./configure --enable-bindings=none UNIVERSAL=1 UNIVERSAL_ARCH="i386 x86_64" ENABLE_OPTIMIZED=1 make sudo env UNIVERSAL=1 UNIVERSAL_ARCH="i386 x86_64" ENABLE_OPTIMIZED=1 make install }}} As of Xcode 3.2.2 it looks like the Xcode team is fixing up some things, rather than some compilers only being in /Developer (or /Developer-BETA, etc.) and gcc being in /usr/bin, all of them are put into /usr/bin. {{{ -rwxrwxr-x 1 root admin 819K Jan 9 23:04 /usr/bin/clang* lrwxr-xr-x 1 root wheel 7B Jan 27 19:46 /usr/bin/g++@ -> g++-4.2 -rwxr-xr-x 1 root wheel 95K Nov 25 06:47 /usr/bin/g++-4.0* -rwxr-xr-x 1 root wheel 162K Dec 22 22:12 /usr/bin/g++-4.2* lrwxr-xr-x 1 root wheel 7B Jan 27 19:46 /usr/bin/gcc@ -> gcc-4.2 -rwxr-xr-x 1 root wheel 95K Nov 25 06:47 /usr/bin/gcc-4.0* -rwxr-xr-x 1 root wheel 162K Dec 22 22:12 /usr/bin/gcc-4.2* lrwxr-xr-x 1 root admin 32B Jan 27 19:46 /usr/bin/llvm-g++@ -> ../llvm-gcc-4.2/bin/llvm-g++-4.2 lrwxr-xr-x 1 root admin 32B Jan 27 19:46 /usr/bin/llvm-g++-4.2@ -> ../llvm-gcc-4.2/bin/llvm-g++-4.2 lrwxr-xr-x 1 root admin 32B Jan 27 19:46 /usr/bin/llvm-gcc@ -> ../llvm-gcc-4.2/bin/llvm-gcc-4.2 lrwxr-xr-x 1 root admin 32B Jan 27 19:46 /usr/bin/llvm-gcc-4.2@ -> ../llvm-gcc-4.2/bin/llvm-gcc-4.2 }}} So, LLVM is now much more likely to fail to build with UNIVERSAL enabled because it is almost guaranteed to find llvm-gcc and llvm-g++ since it finds them by search PATH, and /usr/bin needs to be in PATH. This does work though (setting the compiler specifically as well as telling it to look in a place where llvm-gcc and llvm-g++ are unlikely to exist): {{{ env UNIVERSAL=1 UNIVERSAL_ARCH="i386 x86_64" CC=/usr/bin/gcc CXX=/usr/bin/g++ ./configure --enable-bindings=none --enable-optimzed --with-llvmgccdir=/tmp env UNIVERSAL=1 UNIVERSAL_ARCH="i386 x86_64" CC=/usr/bin/gcc CXX=/usr/bin/g++ make -j2 sudo env UNIVERSAL=1 UNIVERSAL_ARCH="i386 x86_64" CC=/usr/bin/gcc CXX=/usr/bin/g++ make install }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/599> MacRuby <http://macruby.org/>

#553: Fixnum Does Not Appear to Map to NSNumber -------------------------------+-------------------------------------------- Reporter: cwdinfo@… | Owner: lsansonetti@… Type: enhancement | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: -------------------------------+-------------------------------------------- In the context of Cocoa Bindings, Fixnum should "magically" convert to NSNumber much as String becomes NSString.
