Regarding your problem, I may have an idea. In the file datatypes.rb, I define helper methods directly in built-in classes such as IO, String and Array. Most of them are new method names, so there’s no conflict. However, you need to check if some of them are not conflicting.

One I saw is IO#read. Redefining this method was a terrible idea! To fix this, you need to rename it to say _read() and then you need to replace places in the library that use read(). This includes all the read_ methods in datatypes.rb (read_ushort, read_ulong etc).

If you’re able to fix the bug, I can give you access to the Rubyforge project so that you can commit the fix in SVN if you like.

However, I’m now starting to see a strange error in my application that goes away if I comment out my require ‘ttf’ line. Here’s the error:

IOError (Couldn’t load the unicode tables for UTF8Handler (wrong number of arguments (0 for 1)), handler is unusable):

From the stack trace I get I can’t find anywhere that it goes through your code, but there’s definitely something strange going on. Do you have any ideas what that could be?

Thanks again,
Jeremy
