We fixed a few 32-bit issues in trunk so you may want to give it a try
one more time.
At least we are not maintaining 0.4 anymore, so it would be great if
you could try your code with trunk and let us know if the bug is still
there. Then we can try to reduce it and fix it :)

I'm still on a 32-bit machine, so can't try 0.5 yet :^(
I did manage to find a workaround, however, by creating an alias for
the 'initialize' method and then calling it instead of 'super'
inside of the 'define_method' call.

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'
