ChavaScript Parser

A tokenizer/parser for the ChavaScript language, forked from acorn.

Installation

npm install chavascript-parser

Usage

const chsParser = require("chavascript-parser");
 
var code = `
יכולת אחד() {
   יהי א = 12;
   בקרה.תעד(א);
}
`;
const ast = chsParser.parse(code);
console.log(JSON.stringify(ast, null, "  "));

would produce the following abstract syntax tree:
