-<p>
-<b>Update</b>: please read the section on <a href="#sec-1_1">unsafe transformations</a>.
-</p>
-<p>
-This package implements a general-purpose JavaScript
-parser/compressor/beautifier toolkit. It is developed on <a href="http://nodejs.org/">NodeJS</a>, but it
-should work on any JavaScript platform supporting the CommonJS module system
-(and if your platform of choice doesn't support CommonJS, you can easily
-implement it, or discard the <code>exports.*</code> lines from UglifyJS sources).
-</p>
-<p>
-The tokenizer/parser generates an abstract syntax tree from JS code. You
-can then traverse the AST to learn more about the code, or do various
-manipulations on it. This part is implemented in <a href="../lib/parse-js.js">parse-js.js</a> and it's a
-port to JavaScript of the excellent <a href="http://marijn.haverbeke.nl/parse-js/">parse-js</a> Common Lisp library from <a href="http://marijn.haverbeke.nl/">Marijn Haverbeke</a>.
-</p>
-<p>
-( See <a href="http://github.com/mishoo/cl-uglify-js">cl-uglify-js</a> if you're looking for the Common Lisp version of
-UglifyJS. )
-</p>
-<p>
-The second part of this package, implemented in <a href="../lib/process.js">process.js</a>, inspects and
-manipulates the AST generated by the parser to provide the following:
-</p>
-<ul>
-<li>
-ability to re-generate JavaScript code from the AST. Optionally
-indented&mdash;you can use this if you want to “beautify” a program that has
-been compressed, so that you can inspect the source. But you can also run
-our code generator to print out an AST without any whitespace, so you
-achieve compression as well.
-
-</li>
-<li>
-shorten variable names (usually to single characters). Our mangler will
-analyze the code and generate proper variable names, depending on scope
-and usage, and is smart enough to deal with globals defined elsewhere, or
-with <code>eval()</code> calls or <code>with{}</code> statements. In short, if <code>eval()</code> or
-<code>with{}</code> are used in some scope, then all variables in that scope and any
-variables in the parent scopes will remain unmangled, and any references
-to such variables remain unmangled as well.
-
-</li>
-<li>
-various small optimizations that may lead to faster code but certainly
-lead to smaller code. Where possible, we do the following:
-
-<ul>
-<li>
-foo["bar"] ==&gt; foo.bar
-
-</li>
-<li>
-remove block brackets <code>{}</code>
-
-</li>
-<li>
-join consecutive var declarations:
-var a = 10; var b = 20; ==&gt; var a=10,b=20;
-
-</li>
-<li>
-resolve simple constant expressions: 1 +2 * 3 ==&gt; 7. We only do the
-replacement if the result occupies less bytes; for example 1/3 would
-translate to 0.333333333333, so in this case we don't replace it.
-
-</li>
-<li>
-consecutive statements in blocks are merged into a sequence; in many
-cases, this leaves blocks with a single statement, so then we can remove
-the block brackets.
-
-</li>
-<li>
-various optimizations for IF statements:
-
-<ul>
-<li>
-if (foo) bar(); else baz(); ==&gt; foo?bar():baz();
-</li>
-<li>
-if (!foo) bar(); else baz(); ==&gt; foo?baz():bar();
-</li>
-<li>
-if (foo) bar(); ==&gt; foo&amp;&amp;bar();
-</li>
-<li>
-if (!foo) bar(); ==&gt; foo||bar();
-</li>
-<li>
-if (foo) return bar(); else return baz(); ==&gt; return foo?bar():baz();
-</li>
-<li>
-if (foo) return bar(); else something(); ==&gt; {if(foo)return bar();something()}
-
-</li>
-</ul>
-</li>
-<li>
-remove some unreachable code and warn about it (code that follows a
-<code>return</code>, <code>throw</code>, <code>break</code> or <code>continue</code> statement, except
-function/variable declarations).
-</li>
-</ul>
-</li>
-</ul>

-UglifyJS tries its best to achieve great compression while leaving the
-semantics of the code intact. In general, if your code logic is broken by
-UglifyJS then it's a bug in UglifyJS and you should report it and I should
-fix it. :-)
-</p>
-<p>
-However, I opted to include the following potentially unsafe transformations
-as default behavior. Discussion is welcome, if you have ideas of how to
-handle this better, or any objections to these optimizations, please let me
-know.

-The following transformations occur:

-<pre class="src src-espresso"><span style="color: #afeeee; font-weight: bold;">new</span> <span style="color: #87ceeb; font-weight: bold;">Array</span>(1, 2, 3, 4) =&gt; [1,2,3,4]

-</pre>
-
-
-
-<p>
-These are all safe if the Array name isn't redefined. JavaScript does allow
-one to globally redefine Array (and pretty much everything, in fact) but I
-personally don't see why would anyone do that.
-</p>
-<p>
-UglifyJS does handle the case where Array is redefined locally, or even
-globally but with a <code>function</code> or <code>var</code> declaration. Therefore, in the
-following cases UglifyJS <b>doesn't touch</b> calls or instantiations of Array:

-There is a helper script now &mdash; <code>bin/uglifyjs</code> &mdash; that uses the library to
-compress a script using the maximum compression settings. Synopsis:
-</p>
-
-
-
-<pre class="src src-sh">uglifyjs [ options... ] [ filename ]
-</pre>
-
-
-
-<p>
-<code>filename</code> should be the last argument and should name the file from which
-to read the JavaScript code. If you don't specify it, it will read code
-from STDIN.
-</p>
-<p>
-Supported options:
-</p>
-<ul>
-<li>
-<code>-b</code> or <code>--beautify</code> &mdash; output indented code; when passed, additional
-options control the beautifier:
-
-<ul>
-<li>
-<code>-i N</code> or <code>--indent N</code> &mdash; indentation level (number of spaces)
-
-</li>
-<li>
-<code>-q</code> or <code>--quote-keys</code> &mdash; quote keys in literal objects (by default,
-only keys that cannot be identifier names will be quotes).
-
-</li>
-</ul>
-</li>
-<li>
-<code>--ascii</code> &mdash; pass this argument to encode non-ASCII characters as
-<code>\uXXXX</code> sequences. By default UglifyJS won't bother to do it and will
-output Unicode characters instead. (the output is always encoded in UTF8,
-but if you pass this option you'll only get ASCII).
-
-</li>
-<li>
-<code>-nm</code> or <code>--no-mangle</code> &mdash; don't mangle variable names
-
-</li>
-<li>
-<code>-ns</code> or <code>--no-squeeze</code> &mdash; don't call <code>ast_squeeze()</code> (which does various
-optimizations that result in smaller, less readable code).
-
-</li>
-<li>
-<code>-mt</code> or <code>--mangle-toplevel</code> &mdash; mangle names in the toplevel scope too
-(by default we don't do this).
-
-</li>
-<li>
-<code>--no-seqs</code> &mdash; when <code>ast_squeeze()</code> is called (thus, unless you pass
-<code>--no-squeeze</code>) it will reduce consecutive statements in blocks into a
-sequence. For example, "a = 10; b = 20; foo();" will be written as
-"a=10,b=20,foo();". In various occasions, this allows us to discard the
-block brackets (since the block becomes a single statement). This is ON
-by default because it seems safe and saves a few hundred bytes on some
-libs that I tested it on, but pass <code>--no-seqs</code> to disable it.
-
-</li>
-<li>
-<code>--no-dead-code</code> &mdash; by default, UglifyJS will remove code that is
-obviously unreachable (code that follows a <code>return</code>, <code>throw</code>, <code>break</code> or
-<code>continue</code> statement and is not a function/variable declaration). Pass
-this option to disable this optimization.
-
-</li>
-<li>
-<code>-nc</code> or <code>--no-copyright</code> &mdash; by default, <code>uglifyjs</code> will keep the initial
-comment tokens in the generated code (assumed to be copyright information
-etc.). If you pass this it will discard it.
-
-</li>
-<li>
-<code>-o filename</code> or <code>--output filename</code> &mdash; put the result in <code>filename</code>. If
-this isn't given, the result goes to standard output (or see next one).
-
-</li>
-<li>
-<code>--overwrite</code> &mdash; if the code is read from a file (not from STDIN) and you
-pass <code>--overwrite</code> then the output will be written in the same file.
-
-</li>
-<li>
-<code>--ast</code> &mdash; pass this if you want to get the Abstract Syntax Tree instead
-of JavaScript as output. Useful for debugging or learning more about the
-internals.
-
-</li>
-<li>
-<code>-v</code> or <code>--verbose</code> &mdash; output some notes on STDERR (for now just how long
-each operation takes).
-
-</li>
-<li>
-<code>--extra</code> &mdash; enable additional optimizations that have not yet been
-extensively tested. These might, or might not, break your code. If you
-find a bug using this option, please report a test case.
-
-</li>
-<li>
-<code>--unsafe</code> &mdash; enable other additional optimizations that are known to be
-unsafe in some contrived situations, but could still be generally useful.
-For now only this:
-
-<ul>
-<li>
-foo.toString() ==&gt; foo+""
-
-</li>
-</ul>
-</li>
-<li>
-<code>--max-line-len</code> (default 32K characters) &mdash; add a newline after around
-32K characters. I've seen both FF and Chrome croak when all the code was
-on a single line of around 670K. Pass &ndash;max-line-len 0 to disable this
-safety feature.
-
-</li>
-<li>
-<code>--reserved-names</code> &mdash; some libraries rely on certain names to be used, as
-pointed out in issue #92 and #81, so this option allow you to exclude such
-names from the mangler. For example, to keep names <code>require</code> and <code>$super</code>
-intact you'd specify &ndash;reserved-names "require,$super".

-Symlink the <b>lib</b> directory as <b>~/.node_libraries/uglifyjs</b>, so that the

-
-<p>
-The above performs the full compression that is possible right now. As you
-can see, there are a sequence of steps which you can apply. For example if
-you want compressed output but for some reason you don't want to mangle
-variable names, you would simply skip the line that calls
-<code>pro.ast_mangle(ast)</code>.
-</p>
-<p>
-Some of these functions take optional arguments. Here's a description:
-</p>
-<ul>
-<li>
-<code>jsp.parse(code, strict_semicolons)</code> &ndash; parses JS code and returns an AST.
-<code>strict_semicolons</code> is optional and defaults to <code>false</code>. If you pass
-<code>true</code> then the parser will throw an error when it expects a semicolon and
-it doesn't find it. For most JS code you don't want that, but it's useful
-if you want to strictly sanitize your code.
-
-</li>
-<li>
-<code>pro.ast_mangle(ast, options)</code> &ndash; generates a new AST containing mangled
-(compressed) variable and function names. It supports the following
-options:
-
-<ul>
-<li>
-<code>toplevel</code> &ndash; mangle toplevel names (by default we don't touch them).
-</li>
-<li>
-<code>except</code> &ndash; an array of names to exclude from compression.
-
-</li>
-</ul>
-</li>
-<li>
-<code>pro.ast_squeeze(ast, options)</code> &ndash; employs further optimizations designed
-to reduce the size of the code that <code>gen_code</code> would generate from the
-AST. Returns a new AST. <code>options</code> can be a hash; the supported options
-are:
-
-<ul>
-<li>
-<code>make_seqs</code> (default true) which will cause consecutive statements in a
-block to be merged using the "sequence" (comma) operator
-
-</li>
-<li>
-<code>dead_code</code> (default true) which will remove unreachable code.
-
-</li>
-</ul>
-</li>
-<li>
-<code>pro.gen_code(ast, options)</code> &ndash; generates JS code from the AST. By
-default it's minified, but using the <code>options</code> argument you can get nicely
-formatted output. <code>options</code> is, well, optional :-) and if you pass it it
-must be an object and supports the following properties (below you can see
-the default values):
-
-<ul>
-<li>
-<code>beautify: false</code> &ndash; pass <code>true</code> if you want indented output
-</li>
-<li>
-<code>indent_start: 0</code> (only applies when <code>beautify</code> is <code>true</code>) &ndash; initial
-indentation in spaces
-</li>
-<li>
-<code>indent_level: 4</code> (only applies when <code>beautify</code> is <code>true</code>) --
-indentation level, in spaces (pass an even number)
-</li>
-<li>
-<code>quote_keys: false</code> &ndash; if you pass <code>true</code> it will quote all keys in
-literal objects
-</li>
-<li>
-<code>space_colon: false</code> (only applies when <code>beautify</code> is <code>true</code>) &ndash; wether
-to put a space before the colon in object literals
-</li>
-<li>
-<code>ascii_only: false</code> &ndash; pass <code>true</code> if you want to encode non-ASCII
-characters as <code>\uXXXX</code>.

-<p>
-The beautifier can be used as a general purpose indentation tool. It's
-useful when you want to make a minified file readable. One limitation,
-though, is that it discards all comments, so you don't really want to use it
-to reformat your code, unless you don't have, or don't care about, comments.
-</p>
-<p>
-In fact it's not the beautifier who discards comments &mdash; they are dumped at
-the parsing stage, when we build the initial AST. Comments don't really
-make sense in the AST, and while we could add nodes for them, it would be
-inconvenient because we'd have to add special rules to ignore them at all
-the processing stages.

-(XXX: this is somewhat outdated. On the jQuery source code we beat Closure
-by 168 bytes (560 after gzip) and by many seconds.)
-</p>
-<p>
-There are a few popular JS minifiers nowadays &ndash; the two most well known
-being the GoogleClosure (GCL) compiler and the YUI compressor. For some
-reason they are both written in Java. I didn't really hope to beat any of
-them, but finally I did &ndash; UglifyJS compresses better than the YUI
-compressor, and safer than GoogleClosure.
-</p>
-<p>
-I tested it on two big libraries. <a href="http://www.dynarchlib.com/">DynarchLIB</a> is my own, and it's big enough
-to contain probably all the JavaScript tricks known to mankind. <a href="http://jquery.com/">jQuery</a> is
-definitely the most popular JavaScript library (to some people, it's a
-synonym to JavaScript itself).
-</p>
-<p>
-I cannot swear that there are no bugs in the generated codes, but they
-appear to work fine.
-</p>
-<p>
-Compression results:

-</tbody>
-</table>
-
-
-<p>
-UglifyJS is the fastest to run. On my laptop UglifyJS takes 1.35s for
-DynarchLIB, while YUI takes 2.7s and GCL takes 6.5s.
-</p>
-<p>
-GoogleClosure does a lot of smart ass optimizations. I had to strive really
-hard to get close to it. It should be possible to even beat it, but then
-again, GCL has a gazillion lines of code and runs terribly slow, so I'm not
-sure it worths spending the effort to save a few bytes. Also, GCL doesn't
-cope with <code>eval()</code> or <code>with{}</code> &ndash; it just dumps a warning and proceeds to
-mangle names anyway; my DynarchLIB compiled with it is buggy because of
-this.
-</p>
-<p>
-UglifyJS consists of ~1100 lines of code for the tokenizer/parser, and ~1100
-lines for the compressor and code generator. That should make it very
-maintainable and easily extensible, so I would say it has a good place in
-this field and it's bound to become the de-facto standard JS minifier. And
-I shall rule the world. :-) Use it, and <b>spread the word</b>!

-
-
-<p>
-Unfortunately, for the time being there is no automated test suite. But I
-ran the compressor manually on non-trivial code, and then I tested that the
-generated code works as expected. A few hundred times.
-</p>
-<p>
-DynarchLIB was started in times when there was no good JS minifier.
-Therefore I was quite religious about trying to write short code manually,
-and as such DL contains a lot of syntactic hacks<sup><a class="footref" name="fnr.1" href="#fn.1">1</a></sup> such as “foo == bar ? a
-= 10 : b = 20”, though the more readable version would clearly be to use
-“if/else”.
-</p>
-<p>
-Since the parser/compressor runs fine on DL and jQuery, I'm quite confident
-that it's solid enough for production use. If you can identify any bugs,

-#+STYLE: <link rel="stylesheet" type="text/css" href="docstyle.css" />
-#+AUTHOR: Mihai Bazon
-#+EMAIL: mihai.bazon@gmail.com
-
-* UglifyJS --- a JavaScript parser/compressor/beautifier
-
-*Update*: please read the section on [[unsafe transformations]].
-
-This package implements a general-purpose JavaScript
-parser/compressor/beautifier toolkit. It is developed on [[http://nodejs.org/][NodeJS]], but it
-should work on any JavaScript platform supporting the CommonJS module system
-(and if your platform of choice doesn't support CommonJS, you can easily
-implement it, or discard the =exports.*= lines from UglifyJS sources).
-
-The tokenizer/parser generates an abstract syntax tree from JS code. You
-can then traverse the AST to learn more about the code, or do various
-manipulations on it. This part is implemented in [[../lib/parse-js.js][parse-js.js]] and it's a
-port to JavaScript of the excellent [[http://marijn.haverbeke.nl/parse-js/][parse-js]] Common Lisp library from [[http://marijn.haverbeke.nl/][Marijn
-Haverbeke]].
-
-( See [[http://github.com/mishoo/cl-uglify-js][cl-uglify-js]] if you're looking for the Common Lisp version of
-UglifyJS. )
-
-The second part of this package, implemented in [[../lib/process.js][process.js]], inspects and
-manipulates the AST generated by the parser to provide the following:
-
-- ability to re-generate JavaScript code from the AST. Optionally
- indented---you can use this if you want to “beautify” a program that has
- been compressed, so that you can inspect the source. But you can also run
- our code generator to print out an AST without any whitespace, so you
- achieve compression as well.
-
-- shorten variable names (usually to single characters). Our mangler will
- analyze the code and generate proper variable names, depending on scope
- and usage, and is smart enough to deal with globals defined elsewhere, or
- with =eval()= calls or =with{}= statements. In short, if =eval()= or
- =with{}= are used in some scope, then all variables in that scope and any
- variables in the parent scopes will remain unmangled, and any references
- to such variables remain unmangled as well.
-
-- various small optimizations that may lead to faster code but certainly
- lead to smaller code. Where possible, we do the following:
-
- - foo["bar"] ==> foo.bar
-
- - remove block brackets ={}=
-
- - join consecutive var declarations:
- var a = 10; var b = 20; ==> var a=10,b=20;
-
- - resolve simple constant expressions: 1 +2 * 3 ==> 7. We only do the
- replacement if the result occupies less bytes; for example 1/3 would
- translate to 0.333333333333, so in this case we don't replace it.
-
- - consecutive statements in blocks are merged into a sequence; in many
- cases, this leaves blocks with a single statement, so then we can remove
- the block brackets.
-
- - various optimizations for IF statements:
-
- - if (foo) bar(); else baz(); ==> foo?bar():baz();
- - if (!foo) bar(); else baz(); ==> foo?baz():bar();
- - if (foo) bar(); ==> foo&&bar();
- - if (!foo) bar(); ==> foo||bar();
- - if (foo) return bar(); else return baz(); ==> return foo?bar():baz();
- - if (foo) return bar(); else something(); ==> {if(foo)return bar();something()}
-
- - remove some unreachable code and warn about it (code that follows a
- =return=, =throw=, =break= or =continue= statement, except
- function/variable declarations).
-
-** <<Unsafe transformations>>
-
-UglifyJS tries its best to achieve great compression while leaving the
-semantics of the code intact. In general, if your code logic is broken by
-UglifyJS then it's a bug in UglifyJS and you should report it and I should
-fix it. :-)
-
-However, I opted to include the following potentially unsafe transformations
-as default behavior. Discussion is welcome, if you have ideas of how to
-handle this better, or any objections to these optimizations, please let me
-know.
-
-*** Calls involving the global Array constructor
-
-The following transformations occur:
-
-#+BEGIN_SRC espresso
-new Array(1, 2, 3, 4) => [1,2,3,4]
-Array(a, b, c) => [a,b,c]
-new Array(5) => Array(5)
-new Array(a) => Array(a)
-#+END_SRC
-
-These are all safe if the Array name isn't redefined. JavaScript does allow
-one to globally redefine Array (and pretty much everything, in fact) but I
-personally don't see why would anyone do that.
-
-UglifyJS does handle the case where Array is redefined locally, or even
-globally but with a =function= or =var= declaration. Therefore, in the
-following cases UglifyJS *doesn't touch* calls or instantiations of Array:
-
-#+BEGIN_SRC espresso
-// case 1. globally declared variable
- var Array;
- new Array(1, 2, 3);
- Array(a, b);
-
- // or (can be declared later)
- new Array(1, 2, 3);
- var Array;
-
- // or (can be a function)
- new Array(1, 2, 3);
- function Array() { ... }
-
-// case 2. declared in a function
- (function(){
- a = new Array(1, 2, 3);
- b = Array(5, 6);
- var Array;
- })();
-
- // or
- (function(Array){
- return Array(5, 6, 7);
- })();
-

-** Usage
-
-There is a helper script now --- =bin/uglifyjs= --- that uses the library to
-compress a script using the maximum compression settings. Synopsis:
-
-#+BEGIN_SRC sh
-uglifyjs [ options... ] [ filename ]
-#+END_SRC
-
-=filename= should be the last argument and should name the file from which
-to read the JavaScript code. If you don't specify it, it will read code
-from STDIN.
-
-Supported options:
-
-- =-b= or =--beautify= --- output indented code; when passed, additional
- options control the beautifier:
-
- - =-i N= or =--indent N= --- indentation level (number of spaces)
-
- - =-q= or =--quote-keys= --- quote keys in literal objects (by default,
- only keys that cannot be identifier names will be quotes).
-
-- =--ascii= --- pass this argument to encode non-ASCII characters as
- =\uXXXX= sequences. By default UglifyJS won't bother to do it and will
- output Unicode characters instead. (the output is always encoded in UTF8,
- but if you pass this option you'll only get ASCII).
-
-- =-nm= or =--no-mangle= --- don't mangle variable names
-
-- =-ns= or =--no-squeeze= --- don't call =ast_squeeze()= (which does various
- optimizations that result in smaller, less readable code).
-
-- =-mt= or =--mangle-toplevel= --- mangle names in the toplevel scope too
- (by default we don't do this).
-
-- =--no-seqs= --- when =ast_squeeze()= is called (thus, unless you pass
- =--no-squeeze=) it will reduce consecutive statements in blocks into a
- sequence. For example, "a = 10; b = 20; foo();" will be written as
- "a=10,b=20,foo();". In various occasions, this allows us to discard the
- block brackets (since the block becomes a single statement). This is ON
- by default because it seems safe and saves a few hundred bytes on some
- libs that I tested it on, but pass =--no-seqs= to disable it.
-
-- =--no-dead-code= --- by default, UglifyJS will remove code that is
- obviously unreachable (code that follows a =return=, =throw=, =break= or
- =continue= statement and is not a function/variable declaration). Pass
- this option to disable this optimization.
-
-- =-nc= or =--no-copyright= --- by default, =uglifyjs= will keep the initial
- comment tokens in the generated code (assumed to be copyright information
- etc.). If you pass this it will discard it.
-
-- =-o filename= or =--output filename= --- put the result in =filename=. If
- this isn't given, the result goes to standard output (or see next one).
-
-- =--overwrite= --- if the code is read from a file (not from STDIN) and you
- pass =--overwrite= then the output will be written in the same file.
-
-- =--ast= --- pass this if you want to get the Abstract Syntax Tree instead
- of JavaScript as output. Useful for debugging or learning more about the
- internals.
-
-- =-v= or =--verbose= --- output some notes on STDERR (for now just how long
- each operation takes).
-
-- =--extra= --- enable additional optimizations that have not yet been
- extensively tested. These might, or might not, break your code. If you
- find a bug using this option, please report a test case.
-
-- =--unsafe= --- enable other additional optimizations that are known to be
- unsafe in some contrived situations, but could still be generally useful.
- For now only this:
-
- - foo.toString() ==> foo+""
-
-- =--max-line-len= (default 32K characters) --- add a newline after around
- 32K characters. I've seen both FF and Chrome croak when all the code was
- on a single line of around 670K. Pass --max-line-len 0 to disable this
- safety feature.
-
-- =--reserved-names= --- some libraries rely on certain names to be used, as
- pointed out in issue #92 and #81, so this option allow you to exclude such
- names from the mangler. For example, to keep names =require= and =$super=
- intact you'd specify --reserved-names "require,$super".
-
-*** API
-
-Symlink the *lib* directory as *~/.node\_libraries/uglifyjs*, so that the
-*require* calls in the following sample will work:
-
-#+BEGIN_SRC espresso
-var jsp = require("uglifyjs/parse-js");
-var pro = require("uglifyjs/process");
-
-var orig_code = "... JS code here";
-var ast = jsp.parse(orig_code); // parse code and get the initial AST
-ast = pro.ast_mangle(ast); // get a new AST with mangled names
-ast = pro.ast_squeeze(ast); // get an AST with compression optimizations
-var final_code = pro.gen_code(ast); // compressed code here
-#+END_SRC
-
-The above performs the full compression that is possible right now. As you
-can see, there are a sequence of steps which you can apply. For example if
-you want compressed output but for some reason you don't want to mangle
-variable names, you would simply skip the line that calls
-=pro.ast_mangle(ast)=.
-
-Some of these functions take optional arguments. Here's a description:
-
-- =jsp.parse(code, strict_semicolons)= -- parses JS code and returns an AST.
- =strict_semicolons= is optional and defaults to =false=. If you pass
- =true= then the parser will throw an error when it expects a semicolon and
- it doesn't find it. For most JS code you don't want that, but it's useful
- if you want to strictly sanitize your code.
-
-- =pro.ast_mangle(ast, options)= -- generates a new AST containing mangled
- (compressed) variable and function names. It supports the following
- options:
-
- - =toplevel= -- mangle toplevel names (by default we don't touch them).
- - =except= -- an array of names to exclude from compression.
-
-- =pro.ast_squeeze(ast, options)= -- employs further optimizations designed
- to reduce the size of the code that =gen_code= would generate from the
- AST. Returns a new AST. =options= can be a hash; the supported options
- are:
-
- - =make_seqs= (default true) which will cause consecutive statements in a
- block to be merged using the "sequence" (comma) operator
-
- - =dead_code= (default true) which will remove unreachable code.
-
-- =pro.gen_code(ast, options)= -- generates JS code from the AST. By
- default it's minified, but using the =options= argument you can get nicely
- formatted output. =options= is, well, optional :-) and if you pass it it
- must be an object and supports the following properties (below you can see
- the default values):
-
- - =beautify: false= -- pass =true= if you want indented output
- - =indent_start: 0= (only applies when =beautify= is =true=) -- initial
- indentation in spaces
- - =indent_level: 4= (only applies when =beautify= is =true=) --
- indentation level, in spaces (pass an even number)
- - =quote_keys: false= -- if you pass =true= it will quote all keys in
- literal objects
- - =space_colon: false= (only applies when =beautify= is =true=) -- wether
- to put a space before the colon in object literals
- - =ascii_only: false= -- pass =true= if you want to encode non-ASCII
- characters as =\uXXXX=.
-
-*** Beautifier shortcoming -- no more comments
-
-The beautifier can be used as a general purpose indentation tool. It's
-useful when you want to make a minified file readable. One limitation,
-though, is that it discards all comments, so you don't really want to use it
-to reformat your code, unless you don't have, or don't care about, comments.
-
-In fact it's not the beautifier who discards comments --- they are dumped at
-the parsing stage, when we build the initial AST. Comments don't really
-make sense in the AST, and while we could add nodes for them, it would be
-inconvenient because we'd have to add special rules to ignore them at all
-the processing stages.
-
-** Compression -- how good is it?
-
-(XXX: this is somewhat outdated. On the jQuery source code we beat Closure
-by 168 bytes (560 after gzip) and by many seconds.)
-
-There are a few popular JS minifiers nowadays -- the two most well known
-being the GoogleClosure (GCL) compiler and the YUI compressor. For some
-reason they are both written in Java. I didn't really hope to beat any of
-them, but finally I did -- UglifyJS compresses better than the YUI
-compressor, and safer than GoogleClosure.
-
-I tested it on two big libraries. [[http://www.dynarchlib.com/][DynarchLIB]] is my own, and it's big enough
-to contain probably all the JavaScript tricks known to mankind. [[http://jquery.com/][jQuery]] is
-definitely the most popular JavaScript library (to some people, it's a
-synonym to JavaScript itself).
-
-I cannot swear that there are no bugs in the generated codes, but they
-appear to work fine.
-
-Compression results:
-
-| Library | Orig. size | UglifyJS | YUI | GCL |
-|------------+------------+----------+----------------+------------------------|
-| DynarchLIB | 636896 | 241441 | 246452 (+5011) | 240439 (-1002) (buggy) |
-| jQuery | 163855 | 72006 | 79702 (+7696) | 71858 (-148) |
-
-UglifyJS is the fastest to run. On my laptop UglifyJS takes 1.35s for
-DynarchLIB, while YUI takes 2.7s and GCL takes 6.5s.
-
-GoogleClosure does a lot of smart ass optimizations. I had to strive really
-hard to get close to it. It should be possible to even beat it, but then
-again, GCL has a gazillion lines of code and runs terribly slow, so I'm not
-sure it worths spending the effort to save a few bytes. Also, GCL doesn't
-cope with =eval()= or =with{}= -- it just dumps a warning and proceeds to
-mangle names anyway; my DynarchLIB compiled with it is buggy because of
-this.
-
-UglifyJS consists of ~1100 lines of code for the tokenizer/parser, and ~1100
-lines for the compressor and code generator. That should make it very
-maintainable and easily extensible, so I would say it has a good place in
-this field and it's bound to become the de-facto standard JS minifier. And
-I shall rule the world. :-) Use it, and *spread the word*!
-
-** Bugs?
-
-Unfortunately, for the time being there is no automated test suite. But I
-ran the compressor manually on non-trivial code, and then I tested that the
-generated code works as expected. A few hundred times.
-
-DynarchLIB was started in times when there was no good JS minifier.
-Therefore I was quite religious about trying to write short code manually,
-and as such DL contains a lot of syntactic hacks[1] such as “foo == bar ? a
-= 10 : b = 20”, though the more readable version would clearly be to use
-“if/else”.
-
-Since the parser/compressor runs fine on DL and jQuery, I'm quite confident
-that it's solid enough for production use. If you can identify any bugs,
-I'd love to hear about them ([[http://groups.google.com/group/uglifyjs][use the Google Group]] or email me directly).
-
-[1] I even reported a few bugs and suggested some fixes in the original
- [[http://marijn.haverbeke.nl/parse-js/][parse-js]] library, and Marijn pushed fixes literally in minutes.

-
- 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.
