structured

structured.js is a Javascript library that provides a simple interface for static analysis of Javascript code, backed by the abstract syntax tree generated by Esprima. Structured.js works in-browser <script src='structured.js'></script>, or as a standalone npm module.

Examples

var structure = function structure() {
  var _ = _;
  if (_ % 2 == 1) {
    _ += 1;
  }
};
var code = "var a = 11; var b = 1; if (a % 2 == 1) { b += 1;}"
var result = Structured.match(structure, code); // true

Check out the test suite for more.

Demo

demo/demo.html provides a user interface to create and test wildcard structures. The demo page is a good way to get a feel for the analysis and generate QUnit tests.

Tests

Run structured.js tests with npm test or by opening browser-test/index.html.

Dependencies

Esprima and UnderscoreJS for the framework, QUnit for the test suite.
