Package Exports

chevrotain-allstar
chevrotain-allstar/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (chevrotain-allstar) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Chevrotain Allstar

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.

Usage

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()
    }
}
