Package: libjs-uglify-js (3.12.8-1)

JavaScript parser, mangler/compressor and beautifier - browser library

UglifyJS is a JavaScript compressor/minifier written in JavaScript. It also contains tools that allow one to automate working with JavaScript code:

 * A parser which produces an abstract syntax tree (AST) from
   JavaScript code.
 * A code generator which outputs JavaScript code from an AST, also
   providing the option to get a source map.
 * A compressor (optimizer) - it uses the transformer API to optimize
   an AST into a smaller one.
 * A mangler - reduce names of local variables to (usually)
   single-letters.
 * A scope analyzer, which is a tool that augments the AST with
   information about where variables are defined/referenced etc.
 * A tree walker - a simple API allowing you to do something on every
   node in the AST.
 * A tree transformer - another API intended to transform the tree.

All the above utilities and APIs are defined in ~6500 lines of code (except for the effective generation of the source-map, which is handled by the source-map module). Compared to alternatives, UglifyJS is pretty small.

This package provides UglifyJS library directly usable in web browsers.
