Add a rule to the grammar. If the rule already exists, but the implementation differs, an error will be thrown.

Merge this grammar builder with another. It is best to merge the bigger grammar with the smaller one. If the two builders both have a grammar rule with the same name, no error will be thrown case they map to the same ruledef object. If they map to a different object, an error will be thrown. To fix this problem, the overridingRules array should contain a rule with the same conflicting name, this rule implementation will be used.
Change the implementation of an existing grammar rule.
StaticcreateCreate a builder from some initial grammar rules or an existing builder. If a builder is provided, a new copy will be created.
The grammar builder. This is the core of traqula (besides using the amazing chevrotain framework). Using the builder you can create a grammar + AST creator. At any point in time, a parser can be constructed from the added rules. Constructing a parser will cause a validation which will validate the correctness of the grammar.
