Logical assignment support for Acorn

This is a plugin for Acorn - a tiny, fast JavaScript parser, written completely in JavaScript.

It implements support for logical assignments as defined in the stage 3 proposal Logical Assignments. The AST follows ESTree.

Usage

This module provides a plugin that can be used to extend the Acorn Parser class to parse logical assignments. You can either choose to use it via CommonJS (for example in Node.js) like this

var acorn = require('acorn');
var logicalAssignment = require('acorn-logical-assignment');
acorn.Parser.extend(logicalAssignment).parse('x ||= y');

or as an ECMAScript module like this:

import {Parser} from 'acorn';
import logicalAssignment from 'path/to/acorn-logical-assignment.mjs';
Parser.extend(logicalAssignment).parse('x ||= y');
