DotGrammar class

The grammar definition of the Graphviz Dot Language.

You probably don't want to use this yourself, see DotParser.parseGraph instead.

You can find the spec here: https://graphviz.org/doc/info/lang.html. Notable deviations from the spec in this library include:

  • Inability to read files with HTML strings.
  • No restrictions on edge_ops (-- or ->) depending on the type of the current graph.

To learn how to use this grammar definition, check out the documentation for GrammarDefinition and the petitparser package.
