# GLM

A small [GridLab-D](http://gridlab-d.sourceforge.net) markup parser.

Currently incomplete, but does work for simple files.

Includes the executables:

* glm2props - List properties found in file
* glm2dot   - Output a Dot file for use with GraphViz
* glm2json  - Convert GLM format to JSON format

Library functions are also exposesd under:

* GLM.Dot
* GLM.Nesting
* GLM.Parser2
* GLM.Tokenizer
* GLM.JSON

## Library

The main library interface can be found in GLM.Parser.

## glm2dot

Usage:

		Usage: glm2dot [-h|--help] [-e|--edges] [-f|--flatten] [FILE]*

		--flatten    creates new linked nodes for nested nodes
		--edge       only renders nodes that are connected to others


Also accepts GLM format on STDIN.

Example:

		bash-3.2$ head IEEE_4_node.glm
		// Exercise 4.1.1

		clock {
			timestamp '2000-01-01 0:00:00';
			timezone EST+5EDT;
		}

		module powerflow {
			solver_method NR;
		}

		bash-3.2$ glm2dot IEEE_4_node.glm

		digraph {
			// Missed entry ["clock"] - noname
			// Missed entry ["module","powerflow"] - powerflow
			"460bc4159" [label="overhead_line_conductor100"];
			"f98a57e6e" [label="overhead_line_conductor101"];
			"3ae695a1a" [label="line_spacing200"];
			"125c9f13f" [label="line_configuration300"];
			"6666bc20c" [label="transformer_configuration400"];
			"164546f60" [label="node1"];
			"89b8519c3" [label="overhead_line"];
			"164546f60" -> "78882aaeb"; // node1 -> node2
			"78882aaeb" [label="node2"];
			"72f1da2f1" [label="transformer23"];
			"78882aaeb" -> "1315e07dc"; // node2 -> node3
			"1315e07dc" [label="node3"];
			"ff93d9775" [label="overhead_line:34"];
			"1315e07dc" -> "6bf7ab42e"; // node3 -> load4
			"6bf7ab42e" [label="load4"];
		}

Graphical output:

		glm2dot -e IEEE_37node.glm | dot -Tpng -o blah.png && open blah.png
