Copy your clipboard to the pastebin

on Kde, Ruby

Klipper Pastie.org Menu When you are a power IRC user, you might know the problem. You cannot copy the whole source code, error message or log file etc. directly in the IRC channel. You need a pastebin. I like http://pastie.org really much. It has a clean interface and supports highlighting for many languages. But how to copy the text to the pastebin in a handy and short way?

Do the following to copy the clipboard content to the pastebin by a simple <Ctrl>+<Alt>+<R> (global shortcut to open Klipper actions) and a click:

  • Copy the file pastie.rb to a folder which is in your $PATH
  • Make the file executable for you
  • Edit the actions of Klipper and add for the .* Regexp (means: no special string) a new action (do not activate automatic).
  • Add the command echo '%s' | pastie.rb, feedback should go to clipboard and set the description to “post as plain text” for instance
  • You can add another command echo '%s' | pastie.rb -f ruby to paste the text with ruby syntax highlighting

Klipper Pastie.org Settings After that you should be able to send your clipboard to the pastebin with one selection (to copy text into clipboard), one hotkey (to trigger Klipper actions) and one click (to choose between different highlighters). You can paste the URL with a single click on the middle button of your mouse. You don’t even have to open the pastebin page yourself!

I like it. Just want to share this with you in the case you was locking for something similiar. :)

pastie.rb

Copy this file to your ~/bin and make it executable.

A big thank to the unknown author of this file. I found it via google on http://pastie.org and did only some minor modifications on it.

You can use the pastie.rb script via command line by pipe a file to it. To set the code highlighting use the switch -f LANG. To get all supported languages you want to try a pastie.rb -h.
