visualizer library

Classes

GzBaseNode: DOT language Graph Viz markup node. Every node is given a unique key from the ever-increasing GzBaseNode.globalKeys counter. This ensures nodes in the Lua AST can be uniquely identified even if they contain similar content. This is utilized by GzBaseNode.stubId. If a node's label is non-empty, then GzBaseNode.stubLabel will construct the expression to set that attribute in DOT language.
GzChunk: Represents a chunk in a DOT graph as the AST visits every Lua node. It introduces new nodes and links them together in the GzChunk.toString implementation which should be called in GzGraph.toString only.
GzGraph: Represents the graph block in DOT language. Introduces new getters GzGraph.stubHeaders and GzGraph.stubBody which fill the graph with nodes and links them together respectively.
GzNode: Represents a DOT node that has no children.
Visualizer: Walks the AST and generates a new AST corresponding to DOT language nodes which can render a graph for visualizing in DOT preview tools. The highest node will be a GzGraph whose GzGraph.label is "Program".

node(String id, {List<GzBaseNode>? children, String? label, String? color, String? fontColor, String? shape}) → GzBaseNode: A shorthand util that constructs either a GzChunk node or a GzNode based on whether or not children are provided.
quote(String s) → String: Helper util to quote strings.
