This is a lookahead plugin package for the Chevrotain parser library. It implements the ALL(*) lookahead algorithm introduced for ANTLR4. The algorithm features unbounded lookahead, compared to the normal LL(k) behavior of Chevrotain.
When creating your parser, pass an instance of the LLStarLookaheadStrategy
to the lookaheadStrategy
property of the base parser constructor options.
import { LLStarLookaheadStrategy } from "chevrotain-allstar";
class Parser extends EmbeddedActionsParser {
constructor() {
super(tokens, {
lookaheadStrategy: new LLStarLookaheadStrategy()
});
this.performSelfAnalysis()
}
}
