rss module throws exception on including

Hello, I tried to implement a sample photo RSS application according to Apple's tutorial "Building a RubyCocoa Application: A Tutorial" using MacRuby. However, I'm getting such error: ---- /Library/Frameworks/MacRuby.framework/Versions/0.2/usr/lib/ruby/1.9.0/ rss/dublincore.rb:88:in `module_eval': /Library/Frameworks/ MacRuby.framework/Versions/0.2/usr/lib/ruby/1.9.0/rss/dublincore.rb: 123: syntax error, unexpected $end, expecting keyword_end (SyntaxError) target.new_ ^ from /Library/Frameworks/MacRuby.framework/Versions/0.2/usr/lib/ruby/ 1.9.0/rss/dublincore.rb:88:in `block (1 levels) in <module:DublinCoreModel>' from /Library/Frameworks/MacRuby.framework/Versions/0.2/usr/lib/ruby/ 1.9.0/rss/dublincore.rb:87:in `each' from /Library/Frameworks/MacRuby.framework/Versions/0.2/usr/lib/ruby/ 1.9.0/rss/dublincore.rb:87:in `<module:DublinCoreModel>' from /Library/Frameworks/MacRuby.framework/Versions/0.2/usr/lib/ruby/ 1.9.0/rss/dublincore.rb:54:in `<module:RSS>' from /Library/Frameworks/MacRuby.framework/Versions/0.2/usr/lib/ruby/ 1.9.0/rss/dublincore.rb:3:in `<top (required)>' from /Library/Frameworks/MacRuby.framework/Versions/0.2/usr/lib/ruby/ 1.9.0/rss.rb:11:in `require' from /Library/Frameworks/MacRuby.framework/Versions/0.2/usr/lib/ruby/ 1.9.0/rss.rb:11:in `<top (required)>' ---- This error can be reproduced by simply running macirb from the terminal and doing require 'rss'. Same thing happens when I download the latest version of the file dublincore.rb and include it. What's interesting is that this error isn't displayed when I include the same file using plain irb. This probably means that it's not a bug in that file, but in the parser that interprets it. I've tried to download and compile the latest version from trunk and the testing version to check if this happens in those versions too, but I'm unable to install any of them - both of them throw such exception on 'sudo rake install': ---- (in /Users/psionides/Downloads/MacRuby-trunk) ./miniruby instruby.rb --make="/usr/bin/make" --dest-dir="" -- extout=".ext" --mflags="" --make-flags="" --data-mode=0644 --prog- mode=0755 --installed-list .installed.list --mantype="doc" installing binary commands /Users/psionides/Downloads/MacRuby-trunk/lib/fileutils.rb:1259:in `initialize': Is a directory - /Library/Frameworks/MacRuby.framework/ Versions/0.3/usr/bin/ (Errno::EPERM::ENOENT::ESRCH::EINTR::EIO::ENXIO::E2BIG::ENOEXEC::EBADF::ECHILD::EAGAIN::ENOMEM::EACCES::EFAULT::ENOTBLK::EBUSY::EEXIST::EXDEV::ENODEV::ENOTDIR::EISDIR::EINVAL::ENFILE::EMFILE::ENOTTY::ETXTBSY::EFBIG::ENOSPC::ESPIPE::EROFS::EMLINK::EPIPE::EDOM::ERANGE::EDEADLK::ENAMETOOLONG::ENOLCK::ENOSYS::ENOTEMPTY::ELOOP::ENOMSG::EIDRM::ENOSTR::ENODATA::ETIME::ENOSR::EREMOTE::ENOLINK::EPROTO::EMULTIHOP::EBADMSG::EOVERFLOW::EILSEQ::EUSERS::ENOTSOCK::EDESTADDRREQ::EMSGSIZE::EPROTOTYPE::ENOPROTOOPT::EPROTONOSUPPORT::ESOCKTNOSUPPORT::EOPNOTSUPP::EPFNOSUPPORT::EAFNOSUPPORT::EADDRINUSE::EADDRNOTAVAIL::ENETDOWN::ENETUNREACH::ENETRESET::ECONNABORTED::ECONNRESET::ENOBUFS::EISCONN::ENOTCONN::ESHUTDOWN::ETOOMANYREFS::ETIMEDOUT::ECONNREFUSED::EHOSTDOWN::EHOSTUNREACH::EALREADY::EINPROGRESS::ESTALE::EDQUOT::NOERROR) from /Users/psionides/Downloads/MacRuby-trunk/lib/fileutils.rb: 1259:in `open' from /Users/psionides/Downloads/MacRuby-trunk/lib/fileutils.rb: 1259:in `block in copy_file' from /Users/psionides/Downloads/MacRuby-trunk/lib/fileutils.rb: 1258:in `open' from /Users/psionides/Downloads/MacRuby-trunk/lib/fileutils.rb: 1258:in `copy_file' from /Users/psionides/Downloads/MacRuby-trunk/lib/fileutils.rb:462:in `copy_file' from /Users/psionides/Downloads/MacRuby-trunk/lib/fileutils.rb:838:in `block in install' from /Users/psionides/Downloads/MacRuby-trunk/lib/fileutils.rb: 1392:in `block in fu_each_src_dest' from /Users/psionides/Downloads/MacRuby-trunk/lib/fileutils.rb: 1406:in `fu_each_src_dest0' from /Users/psionides/Downloads/MacRuby-trunk/lib/fileutils.rb: 1390:in `fu_each_src_dest' from /Users/psionides/Downloads/MacRuby-trunk/lib/fileutils.rb:834:in `install' from instruby.rb:133:in `install' from instruby.rb:233:in `block in <main>' from instruby.rb:412:in `call' from instruby.rb:412:in `block (2 levels) in <main>' from instruby.rb:409:in `each' from instruby.rb:409:in `block in <main>' from instruby.rb:405:in `each' from instruby.rb:405:in `<main>' rake aborted! ---- Am I doing something wrong?...

0.2 available for testing
by Laurent Sansonetti 18 Jun '08

18 Jun '08

Hi all, Well, after 3 months and a few days of development, 0.2 is now mostly ready to be released. I just merged trunk into the testing branch, please give it a try! $ svn co http://svn.macosforge.org/repository/ruby/MacRuby/branches/testing MacRuby $ cd MacRuby $ autoconf $ ./configure --enable-framework --enable-fat-binary --program- prefix=mac $ make $ sudo make install-nodoc # the `make install' target should now work, but it takes around 15 minutes to generate the RI files, so you might want to skip that step. But at least it should not crash and/or eat all your memory anymore. Unless a big problem is reported, I will release 0.2 next week. In the meantime I will write/port some additional sample code. I also wrote a project roadmap, for the upcoming releases: http://ruby.macosforge.org/trac/wiki/MacRubyRoadmap Some notable 0.2 changes: The String, Array and Hash have been re-implemented using their CoreFoundation equivalent, respectively CFString, CFArray and CFDictionary. For example, String is not a class anymore but a shortcut (alias) to NSMutableString. The whole String interface has been re-implemented on top of NSString. Every string created by MacRuby is therefore a CFString/NSString, and can be passed without any conversion to an underlying API that expects a CFString/NSString. Same thing for Array and Hash. All well-known GC crashers and memory leaks have been fixed. Lots of bugs have also been fixed. irb/erb/rdoc/ri should work! The 1.9 source base was synchronized with the upstream trunk. The new 1.9 APIs introduced since the latest snapshot were implemented. Laurent
