-/**
- * @fileoverview Enhances UglifyJS with consolidation of null, Boolean, and String values.
- * Also known as aliasing, this feature has been deprecated in the Closure Compiler since its
- * initial release, where it is unavailable from the CLI. The Closure Compiler allows one to log and
- * influence this process. In contrast, this implementation does not introduce
- * any variable declarations in global code and derives String values from
- * identifier names used as property accessors.
- * Consolidating literals may worsen the data compression ratio when an encoding
- * transformation is applied. For instance, jQuery 1.7.1 takes 248235 bytes.
- * Building it with
- * UglifyJS v1.2.5 results in 93647 bytes (37.73% of the original) which are
- * then compressed to 33154 bytes (13.36% of the original) using gzip(1). Building it with the same
- * version of UglifyJS 1.2.5 patched with the implementation of consolidation
- * results in 80784 bytes (a decrease of 12863 bytes, i.e. 13.74%, in comparison
- * to the aforementioned 93647 bytes) which are then compressed to 34013 bytes
- * (an increase of 859 bytes, i.e. 2.59%, in comparison to the aforementioned
- * 33154 bytes).
- * Written in the strict variant
- * of ECMA-262 5.1 Edition. Encoded in UTF-8. Follows Revision 2.28 of the Google JavaScript Style Guide (except for the
- * discouraged use of the {@code function} tag and the {@code namespace} tag).
- * 100% typed for the Closure Compiler Version 1741.
- * Should you find this software useful, please consider a donation.

-
- A JavaScript tokenizer / parser / beautifier / compressor.
-
- This version is suitable for Node.js. With minimal changes (the
- exports stuff) it should work on any JS platform.
-
- This file contains the tokenizer/parser. It is a port to JavaScript
- of parse-js [1], a JavaScript parser library written in Common Lisp
- by Marijn Haverbeke. Thank you Marijn!
-
- [1] http://marijn.haverbeke.nl/parse-js/
-
- Exported functions:
-
- - tokenizer(code) -- returns a function. Call the returned
- function to fetch the next token.
-
- - parse(code) -- returns an AST of the given JavaScript code.

-
- A JavaScript tokenizer / parser / beautifier / compressor.
-
- This version is suitable for Node.js. With minimal changes (the
- exports stuff) it should work on any JS platform.
-
- This file implements some AST processors. They work on data built
- by parse-js.
-
- Exported functions:
-
- - ast_mangle(ast, options) -- mangles the variable/function names
- in the AST. Returns an AST.
-
- - ast_squeeze(ast) -- employs various optimizations to make the
- final generated code even smaller. Returns an AST.
-
- - gen_code(ast, options) -- generates JS code from the AST. Pass
- true (or an object, see the code for some options) as second
- argument to get "pretty" (indented) code.
