+ * @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).

+
+ 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.

-/**
- * @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).
