Asp Forum - Clipboard command line utility

I've been doing a lot of Python for Google's Highly Open Participation
contest lately but finally found the time to make a utility I thought
of a few weeks ago. Basically, it allows you to pipe to and from the
clipboard on the command line. Example:

daniel@daniel-desktop:~$ echo 'ruby' | clipboard
daniel@daniel-desktop:~$ clipboard
ruby
daniel@daniel-desktop:~$

You can also access it with the normal Control-C/Control-V shortcuts.

So, it's a great concept, but not such a good implementation. First,
I doctored the output above. ruby-gnome2 seems to be outputting error
messages that I can't get rid of, even after a Google search. This is
the real output:

daniel@daniel-desktop:~$ echo 'ruby' | clipboard
/usr/lib/ruby/1.8/glib2.rb: line 55
GLib-GObject-CRITICAL **:g_boxed_type_register_static: assertion

ruby
daniel@daniel-desktop:~$

I have tried doing something like this with stderr, stdout, and defout
with no luck:
require 'stringio'

old_stderr = $stderr
$stderr = StringIO.new

require 'gtk2'

$stderr = old_stderr

Any suggestions?

I have posted the full source code to http://ruby.pastebin.com...

I would also like a better way to capture STDIN without blocking if
there is no text on STDIN.

Thanks,

I have seen these errors as well, you will have better luck if you
compile ruby-gnome2 directly from SVN.
Yeah, it has lots of dependencies, but probably you will have them.

I will love to play with code and see where it takes me!

I'm not saying you shouldn't write this utility -- I've been known to
duplicate existing utilities at times, too, sometimes with a good reason
and sometimes for less-good reasons. However . . .

Are you aware there's a commonly available utility for this already
called xclip? I use it pretty extensively.

ren@kokopelli:~> echo 'ruby'|xclip
ren@kokopelli:~> xclip -o
ruby
ren@kokopelli:~> cat books.txt
Policy Made Easy
ren@kokopelli:~> xclip books.txt
ren@kokopelli:~> xclip -o
Policy Made Easy
ren@kokopelli:~>

. . et cetera.

FreeBSD:
root@host:/> portinstall xclip
(assuming you use portupgrade)

Debian:
root@host:/# apt-get install xclip

If you already knew about xclip, I'm curious why you are writing what
amounts to a Ruby replacement for it. Are you just practicing? Do you
want to rewrite a bunch of utilities in Ruby kinda like the Perl Power
Tools? Do you dislike the xclip licensing?

Feel free to refuse to cater to my idle curiosity. I'm just nosy that
way.

There are probably a many reasons, I do not know why he wants to have
this,
but one thing which immediately comes to my mind is:

- To have the same functionality available in pure ruby, without
depending on
some C program like xclip. :)

I actually did not know about xclip, I wrote the utility to use it, not as
an exercise. Thanks for the link.

Do you have any other favorite command line utilities?

Thanks,
