Overview

A little tool to help visualize a parse tree. It generates .dot files parsable by graphviz. If you have graphviz installed, you may be able to invoke it like so and generate a .png file

Gullah::Dotifier.dot parses.first, "tree", make_it: :so

This will generate a file called tree.png showing the parse tree. If you don’t have graphviz, or perhaps if you’re on a machine which doesn’t like the command this generates – I suspect Windows doesn’t – you can skip the named argument and just generate the dot file which you can feed into graphviz some other way.

I make no guarantees about this utility. You may want to build your own, in which case this can serve as a simple prototype.

Class Method Details

.dot(parse, file, make_it: false, type: 'png') ⇒ Object

Receives a parse and a file name and generates a graph specification readable by graphviz. The specification is written to a file with the specified file name. If make_it is truthy, the dot command will also be invoked and the graph image generated. By default this will be a png, though the type is specifiable via the type named argument.
