Scaladiagrams is a command line tool to generate DOT files representing a Scala projects class hierarchy. These DOT files can then be passed to a renderer such as GraphViz to draw the hierarchy.

Usage

First, compile and package with ./build

To run Scaladiagrams do the following:

scaladiagrams --source pathToScalaSourcefiles > dotFile

If you have Graphviz installed, you can generate an image like so:

scaladiagrams --source pathToScalaSourcefiles | dot -Tpng > file.png

Large class hierarchies are probably best rendered as an SVG file, just replace the target in dot.

Other options

./scaladiagrams --help
	-e, --extension  <arg>    (default = .scala) 
	-l, --linked             only output types that extend other types 
	-s, --source  <arg>      location of source files (default = .)

Most useful of these is -l, to remove types that do not inherit anything and are not inherited.
