ParseJS is a JavaScript parser for Dart. It is well-tested and is reasonably efficient.
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
})
}
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 onNode.filename
and onParseError.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 initializeNode.parent
,Scope.environment
, andName.scope
, to simplify subsequent AST analysis. Default is true.parseAsExpression
: If true, the input will be parsed as an expression statement.
