debugging question

eggman2001

10/18/2007 4:00:00 AM

I run this one gem with the command "foo <options>". I'd like to try
to run it off the foo.rb file so that I can debug it. However, when I
do "ruby path/to/foo.rb <options>" it doesn't behave in the same way
as "foo <options>". How do I need to run this program in order to
debug it?

maybe first
require 'rubygems'
then require the file,
maybe run it from within that directory.
maybe do Dir.chdir to it, first, then require.

Specifics would be nice, as I don't quite understand what you're trying
to do. "run a gem"?

so I installed the gem rdig. You run rdig with "rdig <options>" and
I'd like to debug it.

I tried that, but it doesn't work.

Here's the error that I'm getting...

checkout the topmost file line.
Maybe you're trying to run something on a port in use?

Not quite sure what you mean - sorry. I know very little about the
role that ports play in these situations.

go into the rdig file (find it), then add
require 'ruby-debug'
debugger

and it should open a breakpoint for you there (run it normal).

IIRC, M*A*S*H's Fr. Mulcahy guested on MURDER, SHE WROTE. He ended up
being the killer and he was ... a bird watcher.

That's the only one that comes to mind for me, though.

I've seen about 4 characters who were birdwatchers (or claimed to be) on
TV, and they were all murderers.
