MacRuby not finding a method that Ruby is
by Edward Hynes 09 Oct '09

09 Oct '09

Hi, I'm attempting to use the RParsec gem under MacRuby, but am getting a NoMethodError when it loads. I've create a test file that simply adds my local gem directory to the front of the library search path and then calls "require 'rparsec'". This file runs fine under Ruby 1.9, but produces the following error when called from MacRuby 0.4. /Users/ehynes/Test/Gems/rparsec/parser.rb:32:in `block in init': super: no superclass method `initialize:' for RParsec::ValueParser:RParsec::ValueParser (NoMethodError) from /Users/ehynes/Test/Gems/rparsec/parsers.rb:621:in `new' from /Users/ehynes/Test/Gems/rparsec/parsers.rb:621:in `<module:RParsec>' from /Users/ehynes/Test/Gems/rparsec/parsers.rb:3:in `<top (required)>' from /Users/ehynes/Test/Gems/rparsec.rb:3:in `require' from /Users/ehynes/Test/Gems/rparsec.rb:3:in `block in <top (required)>' from /Users/ehynes/Test/Gems/rparsec.rb:2:in `each' from /Users/ehynes/Test/Gems/rparsec.rb:2:in `<top (required)>' from AbcParser.rb:2:in `require' from AbcParser.rb:2:in `<main>' The method with the error in the Parser class is: def self.init(*vars) parser_checker = {} vars.each_with_index do |var, i| name = var.to_s parser_checker[i] = var if name.include?('parser') && ! name.include?('parsers') end define_method(:initialize) do |*params| ---> super() # <--- line 32 vars.each_with_index do |var, i| param = params[i] if parser_checker.include? i TypeChecker.check_arg_type Parser, param, self, i end instance_variable_set("@"+var.to_s, param) end end end Any ideas as to why Ruby can call super in the above method, but MacRuby can't? Is there a fix or workaround that I could use? An alternate parser? Thanks, Ed P.S. I did have to change one line in the RParsec parser.rb file to get it to run under Ruby 1.9, replacing a ':' with a 'then' in a case statement. $ diff parser_original.rb parser.rb 881c881 < case c when String: c[0] else c end --- > case c when String then c[0] else c end # ':' replaced with 'then'

macruby in a bubble
by Diego Virasoro 08 Oct '09

08 Oct '09

Hello, I'd like to try MacRuby (especially now that 0.5 beta 1 is out). However I really really _really_ like to avoid having programs spread their files across my fs. So, the questions are: 1) Is it possible to install macruby inside a specified directory? 2) Are any other files modified (say the .profile to extend the $PATH, or others)? 3) Especially if the answer to 1) is negative, is there a script file to erase/uninstall macruby? Thanks and congrats for an awsome project Diego

Link Error in 0.5b1 blog post announcement
by Keith Gautreaux 08 Oct '09

08 Oct '09

FYI, the "report us" link the in third paragraph of the 0.5b1 announcement on macruby.org has a link error. It should be top-level (http://macruby.org/contact-us.html) but instead is under the blog/2009/10/07 hierarchy. I tried to fork the site on github and make a diff but the github mirror seems to be lagging behind (last commit is from 10/2/09). -- Keith
