JSCheck

JSCheck is a Javascript syntax checker for the full ECMAScript 3, without any additional style constraint. See it as complementary to JSLint ("simplified Javascript" subset, with style constraints).

Thanks: to Brendan Eich & Mozilla for the original SpiderMonkey Narcissus parser (which I ported to other browsers & engines), to Stefan Weiss for mentionning Narcissus, and to Jerome Wagner for his bug fix.

JSCheck also runs within the Google V8 Engine (e.g. in the unit tests), as do other Narcissus-based tools.

• narcissus.code.compress.js: ECMAScript 3 compression (also integrated into a build system).
• narcissus.code.equal.js: Compare two programs (independent of spaces, comments and local names).
• narcissus.jsdef.js: The Narcissus token definitions (cross-browser/engine port of jsdef_original.js).
• narcissus.jsparse.js: The Narcissus parser (cross-browser/engine port of jsparse_original.js), which produces a Narcissus tree.
• narcissus.tree2code.js: Generate code from a Narcissus tree.
• narcissus.tree.equal.js: Compare two Narcissus trees.
• narcissus.tree.js: Core tools to analyze and recurse-walk through a Narcissus tree.
• narcissus.tree.scope.js: Walk through a Narcissus tree and produce a list of scopes, with for each scope a list of local variable names.
• proto.js: minimalistic inheritance for ECMAScript 3.

/*global a,b,c*/

a = 123;
b = 'foo';
c = { t: 123, z: '765' };

/*global*/d = 456;

/*global*/f = function (x, y) { do_something; };

/*prep -> */   (click the edit button for examples)

/*global*/f = (x, y)->{ do_some; return thing; };
/*global*/g = (x, y)->{ return x + y; }
/*global*/h = (x, y)->x + y; // Shortcut

/*prep tailopt*/ (⇒ production examples)

/*prep ->,tailopt*/ Multiple prep. (order matters)

JSCheck, yeah, a JS Check code checker for JavaScript code, well JS. All checked, right?
