Charmworld uses virtualenv to isolate the environment. In order to add a new package as a requirement you need to add it to the requirements.txt file and make sure you lock the version.
The make target make deps will then install the new dependency.
Note The package must exist in the download cache. See lp:~juju-jitsu/charmworld/download-cache.
Charmworld is currently using the Ubuntu CSS framework. Additional classes may be added in static/css/base.css but that should be avoided unless absolutely necessary.
You can use a tool like watchdog to auto update the css when you’re hacking on it. A sample watchdog command would be:
bin/watchmedo shell-command \
--patterns="*.less" \
--command='make css' charmworld/static/css/
# Canonistack
$ source ~/.canonistack/novarc

$ juju status
# Wait for environment to come up

$ juju set mongodb dbpath=/mnt/mongodb

$ juju expose charmworld

Running locally will install a number of packages, but if you don’t mind it is a fine way to proceed.
