Changing Clipboard Data From The Shell

Jwsh: Version 1.1.0 - use simpler and more reliable get/put functions to update the clipboard

== Changing Clipboard Data From The Shell ==

When you use the copy and paste function on your Pre the string has to go somewhere. Right? Well, from what I learned from '''tharris''' which was that the string goes to a file called '''webkit-clipboard''' which is located in the '''/tmp''' directory.

== Manual Steps ==

'''Step One:''' Access the Linux portion of your Pre

'''Step Two:''' Edit your clipboard file '''(you need to at least copy and paste something once for the file to show up)'''

<pre>
vi /tmp/webkit-clipboard
</pre>

'''Step Three:''' Save it.

'''Tip:''' for more info on how to use vi, remember Google is your friend...

== WebOS Clipboard Buddy ==

'''WebOS Clipboard Buddy''' is a very simple pyGTK app that allows you to easily copy data between your desktop's clipboard and the Pre's clipboard. Feel free to improve upon it. Currently this is Linux only, though it should be trivial to get working under windows. It currently requires that you have the SDK installed (specifically that novacom is functional and available at /usr/local/bin/novacom/novacom).

I just added '''WebOS Clipboard Buddy''' directly to this page, if someone wants to put it into an appropriate code repository, that's fine by me. I tried to upload it instead of dumping the code directly in, but .py attachments were not allowed.
