Simple Gridlab-D GLM parser and utilities.

GLM

A small GridLab-D 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.

glm2json

glmprops

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"];
	}
