Subject: tk.rb: incompatible change between 1.8.1 and 1.8.2

Hi all,

The "can't dup Fixnum" error what I have mentioned in my previous post
is caused by a change in tk.rb.

The tk.rb in 1.8.1 has the following portion from line 657:

module TkCore
  include TkComm
  extend TkComm

  unless self.const_defined? :INTERP
    if self.const_defined? :IP_NAME
      name = IP_NAME.to_s
    else
      name = nil
####  ^^^^^^^^^^  #####################
    end
    if self.const_defined? :IP_OPTS
      if IP_OPTS.kind_of?(Hash)
        opts = hash_kv(IP_OPTS).join(' ')
      else
        opts = IP_OPTS.to_s
      end
    else
      opts = ''
    end

    INTERP = TclTkIp.new(name, opts)
[...]

The 1.8.2 version has this (from line 940):

module TkCore
  include TkComm
  extend TkComm

  unless self.const_defined? :INTERP
    if self.const_defined? :IP_NAME
      name = IP_NAME.to_s
    else
      #name = nil
      name = $0
####  ^^^^^^^^^^  #####################
    end
    if self.const_defined? :IP_OPTS
      if IP_OPTS.kind_of?(Hash)
        opts = hash_kv(IP_OPTS).join(' ')
      else
        opts = IP_OPTS.to_s
      end
    else
      opts = ''
    end

    INTERP = TclTkIp.new(name, opts)

(The version numbers are from the debian packages.)

This change causes the fixnum problem in class TclTkExtIp's constructor.

I have a 1.8.0 source where TclTkIp's initialize fn (in tcltklib.c) do
not get params, so I do not know why is it for.

What to do?

Thanks,
Ferenc
