Subject: Re: TCL interpreter in Ruby?

Thanks,  I have been playing with this all day and have made some 
discoveries, but I still need some help.

I have written the following:

def Tk.load_tcl_script(file)
  begin 
    Tk.tk_call('source', file)
  rescue
    puts $!
  end
end


The $! gives the error found during the Tk call 
(for example, wrong # args: should be "set varName ?newValue?")
But, I also want to report the current line number and stack
trace of the tcl error.  (To be more exact, I want the output
to look exactly like the error output when running tclsh.)

Is there any way to accomplish this?



On a side note, I finally figured out the call backs in tcl.
  
tcl syntax (in the tcl file):
ruby { ruby_method(arg1, arg2...) }

ruby syntax:
def ruby_method(arg1, arg2,...)
....
end

Tk.load_tcl_script(file)
