visualize clara rule engine namespaces

claravis

A Leiningen plugin for visualizing Clara rule data flow.

Clara Rule Engine is a super cool project. But sometimes the data flow can get messy due to the high number of rules and facts. This project helps you visualize your data flow in order to catch bugs more efficiently.

Usage

1. Clone this repo somewhere git clone https://github.com/erdos/claravis
2. Go to repo directory and install mvn dependency: $ lein install
3. Add the following to the :plugins section of your project.clj file: [claravis "0.1.0-SNAPSHOT"]
4. Make sure Graphviz is installed in your system.
5. In the project folder execute the command: $ lein claravis my.namespace.core output.png
6. See the generated graph in the output.png file.

Pro tip: you can add the plugin to your ~/.lein/profiles.clj instead of project.clj if you wish to use it across multiple projects.

Example

This is the generated example for the clara.examples.shopping namespace of the Clara Examples repository.

The tabular data are the facts and the brown boxes are the rules. You can see the queries at the bottom.
