Programming

I’ve only been coding Python for ~12 hours total, so don’t expect this to be perfect. Knowing what I know about creating/testing other software and doing my best to scour through very light pynotify documentation, I’ve begun to build out this script to be more useful / portable / configurable. As the Version 0.6 indicates, I’m not quite at my goal yet and there is still more to learn to bring it up to that point.

I’m releasing this early on my blog just in case I caught any people yesterday who’ve been experimenting with my research / code so far. I’ll share it on github when I evolve it just a bit more.

# Title: scp-notifications
# Author: Tyler Mulligan (tyler@detrition.net)
# Date: 06/26/2010
# Version: 0.6
# Description:
# Used in combination with an event, such as an action or cronjob, this script
# will scp the latest file from a folder to your server.
#
# Optionally, it can copy the url to your clipboard and/or show a popup with a
# link to the file after succesfully uploading
#
# Orginally developed to be piped to from compiz screenshot tool
# http://interwebninja.com/videos/compiz-screenshot-piped-to-notification-daemon-for-upload.ogv
