parsejs 1.2.0

JavaScript parser.

ParseJS

ParseJS is a JavaScript parser for Dart. It is well-tested and is reasonably efficient.

Example Usage

import 'package:parsejs/parsejs.dart';

void main() {
    new File('test.js').readAsString().then((String code) {
        Program ast = parsejs(code, filename: 'test.js')
        // Use the AST for something
    })
}

Options

The parsejs function takes the following optional arguments:

• filename: An arbitrary string indicating where the source came from. For your convenience this will be available on Node.filename and on ParseError.filename.
• firstLine: The line number to associate with the first line of code. Default is 1. Useful if code was extracted from an HTML file, and you prefer absolute line numbers.
• handleNoise: If true, parser will try to ignore hash bangs and HTML comment tags surrounding the source code. Default is true.
• annotate: If true, parser will initialize Node.parent, Scope.environment, and Name.scope, to simplify subsequent AST analysis. Default is true.
• parseAsExpression: If true, the input will be parsed as an expression statement.
