JavaScript API to "unparse" any nearley grammar. Also allows overrides for given grammar rules.

var grammar = require("./grammar");

API
src = unparse(grammar[, options])
options.start
which rule to start the unparser. (default:grammar.ParserStart
)options.override_rule
a map where the keys are the rule name and the value is a function that returns a string for that rule.options.filterRule
a function that will take in a rule and return true if it should be selected. This is handy when you want to exclude rules like paren wrapping so it doesn't just output something like this:(((((1)))))
options.max_stack_size
useful to limit how deeply nested rules are. (default: 25)options.max_loops
useful to keep it from running "forever". (default: 500)
