This is a collection of tools to make writing Juju charms easier. See Juju's home page for more information.

First, you'll need Juju. If its not available in your version of Ubuntu you can use the PPA:

sudo add-apt-repository ppa:juju/stable
sudo apt-get update
sudo apt-get install juju-core

Most people will want to install charm-tools from the Juju PPA.

sudo apt-get install charm-tools

Alternatively you can download the project and run the tip of the code.

git clone http://github.com/juju/charm-tools
cd charm-tools

In order to use any of these tools you need to have Juju setup and working in your path

To generate a new charm from a Debian package available on your system

juju charm create foo

This should add a directory to charms with the name foo, and some of the metadata.yml and hooks filled in. It will create these in $CHARM_HOME or under the current working directory.

To perform basic static analysis on a charm, run

juju charm proof foo

It will analyze the charm for any obvious mistakes.

Retrieves all of the charms in the charm distribution via bzr.

This is used to check the quality of maintainer<->bug subscriptions in launchpad since we do not have this relationship automatically setup.

As a maintainer, if you would like to ensure that you are subscribed to all of your charms you can run this command:

juju charm subscribers --fix-unsubscribed --maintainer [email protected] --repository path/to/your/charms
