It was a bit fiddly, but here's something that works:
In Gedit go to Tools=>Manage External Tools...
Then add this:
Here's the code:
#!/bin/sh EHOME=`echo $HOME | sed "s/#/\#/"` DIR=$GEDIT_CURRENT_DOCUMENT_DIR while test "$DIR" != "/"; do if [ -f "${DIR}/setup.py" ]; then echo "Using quickly from ${DIR}" | sed "s#$EHOME#~#" > /dev/stderr cd ${DIR} quickly run exit fi DIR=`dirname "${DIR}"` done echo "Couldn't find Quickly project folder!" > /dev/stderr
Hope this helps you too.
