Full Description

Lindenmayer Systems





NOTE This project is currently undergoing significant rework

An L-System or Lindenmayer system is a parallel rewriting system, namely a
variant of a formal grammar, most famously used to model the growth
processes of plant development, but also able to model the morphology of
a variety of organisms.

This project is written using Clojure, demonstrating L-System
re-writing, deployed to Heroku:

Pre-defined examples can be generated using these links:

Pre-requisites

You will need Leiningen 2.6.1 or above installed.

Building

To build and start the service locally, run:

$ cd lindenmayer-systems
$ lein deps
$ lein ring server-headless

To build and run a standalone jar:

$ lein ring uberjar
$ java -jar target/lindenmayer-systems-0.2.0-SNAPSHOT-standalone.jar

In both instances, the webapp starts on http://localhost:3000.

Docker image

A docker image is available as richardhull/lindenmayer-systems,
and can be downloaded and started with:

$ docker pull richardhull/lindenmayer-systems
$ docker run --name lindenmayer-systems -d -p 3000:3000 richardhull/lindenmayer-systems
