is a regular grammar), then it can be applied directly to a string by calling it on that string. In addition, if a rule is compiled without reference to another expression (i.e. For instance, if you compiled an expression that matches on two consecutive integers, when this rule is applied to a string with two integers, it will pass an array with both those integers to the function passed to apply. apply() function that can be passed another function that is called with the value that this expression matched. Rules that are compiled with pile expose a. pile(rule) takes a grammar string and compiles it into a tyranny rule. These rules can either be a string (as defined in the section Grammar Syntax) or as a compiled grammar from pile. Tyrant.addRules(rules), like addTokens takes a single parameter which represents a key value pair of grammatical expression names, with the rules that define them. Make sure all rules start with ^ and end with $! tyrant.addRules(rules) This will be used in the lexing step, and will be available to your grammar. Tyrant.addTokens(tokens) takes a single parameter, tokens which represents a key value pair mapping token names to a regular expression that defines them. For Jury to determine the sentence, it needs a set of rules that are defined using a regular expression-like sentence tyrant.addTokens(tokens) This can be registered as an object whose keys are the token names, and the values are regular expressions that select each token.

For Judge to tokenize a string, it needs a set of rules for tokening. Specifying a grammar requires input for each of the three steps. Each tyrant can only parse one grammar, but it can have multiple rules. New tyranny.tyrant() returns a new tyrant. Executioner - Applies a mapping function to each sentence element based on its location in the string.Jury - Compares the tokenized string against a grammar, and if it is valid determines the sentence.Judge - Judges whether an input string can be tokenized, and returns its token value if so.

Tyranny is a node module that allows for the tokenization, parsing, and mapping of arbitrary regular, and context free grammars using a regular expression like syntax.
