'require' to fill $" with long names?

ruby-talk
1

Require fills $" with (the short names of) the library files it
is able to find. When the program has ended, RubyScript2Exe
tries to match the libraries in $" with the directories in $:
and the default extensions in order to collect the files. But,
since $: might change when running the program (RubyGems!...),
the files RubyScript2Exe finds are not necessarily the ones
Ruby finds.

I came up with this solution (see below). Just redefine require
before executing the application and $" will be filled with the
full names of the library files. Seems to work....

Any suggestions or considerations?

alias :old_require :require

def require(lib, *rest)
   extensions = ["", ".rb", ".so", ".o", ".dll"]
   search_list = $:.collect{|dir| extensions.collect{|ext|
File.expand_path(lib + ext, dir)}}.flatten
   found = search_list.find{|file| File.file?(file)}
   lib = found unless found.nil?

   old_require(lib, *rest)
end

1.9 does so.

1.9 does so.

Quick check...

Well, uh, just partly. It does expand all pathes, except for
enumerator.so. Where does enumerator.so come from? Why isn't it
a full path?

Running on Cygwin on XP.

$ ./ruby.exe -v
ruby 1.9.0 (2005-10-04) [i386-cygwin]

$ ./ruby.exe -e 'p $"'
["enumerator.so"]

$ ./ruby.exe -r rbconfig -e 'p $"'
["enumerator.so", "/scratch/snapshot/ruby/rbconfig.rb"]

It is built-in now, and defined for backward compatibility
purpose.
