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.
