-<div class="outline-text-2" id="text-1">
-
-
-<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—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"] ==> foo.bar
-
-</li>
-<li>
-remove block brackets <code>{}</code>
-
-</li>
-<li>
-join consecutive var declarations:
-var a = 10; var b = 20; ==> var a=10,b=20;
-
-</li>
-<li>
-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.
-
-</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(); ==> foo?bar():baz();
-</li>
-<li>
-if (!foo) bar(); else baz(); ==> foo?baz():bar();
-</li>
-<li>
-if (foo) bar(); ==> foo&&bar();
-</li>
-<li>
-if (!foo) bar(); ==> foo||bar();
-</li>
-<li>
-if (foo) return bar(); else return baz(); ==> return foo?bar():baz();
-</li>
-<li>
-if (foo) return bar(); else something(); ==> {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>

-<div class="outline-text-3" id="text-1_1">
-
-
-<p>
-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.

-<h4 id="sec-1_1_1"><span class="section-number-4">1.1.1</span> Calls involving the global Array constructor </h4>
-<div class="outline-text-4" id="text-1_1_1">
-
-
-<p>
-The following transformations occur:
-</p>
-
-
-
-<pre class="src src-js"><span style="color: #8b0000;">new</span> <span style="color: #4682b4;">Array</span>(1, 2, 3, 4) => [1,2,3,4]
-Array(a, b, c) => [a,b,c]
-<span style="color: #8b0000;">new</span> <span style="color: #4682b4;">Array</span>(5) => Array(5)
-<span style="color: #8b0000;">new</span> <span style="color: #4682b4;">Array</span>(a) => Array(a)
-</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:

-<div class="outline-text-3" id="text-1_4">
-
-
-<p>
-There is a command-line tool that exposes the functionality of this library
-for your shell-scripting needs:
-</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> — output indented code; when passed, additional
-options control the beautifier:
-
-<ul>
-<li>
-<code>-i N</code> or <code>--indent N</code> — indentation level (number of spaces)
-
-</li>
-<li>
-<code>-q</code> or <code>--quote-keys</code> — quote keys in literal objects (by default,
-only keys that cannot be identifier names will be quotes).
-
-</li>
-</ul>
-</li>
-<li>
-<code>--ascii</code> — 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> — don't mangle variable names
-
-</li>
-<li>
-<code>-ns</code> or <code>--no-squeeze</code> — 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> — mangle names in the toplevel scope too
-(by default we don't do this).
-
-</li>
-<li>
-<code>--no-seqs</code> — 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> — 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> — 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> — 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> — 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> — 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> — output some notes on STDERR (for now just how long
-each operation takes).
-
-</li>
-<li>
-<code>--extra</code> — 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> — 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() ==> foo+""
-
-</li>
-</ul>
-</li>
-<li>
-<code>--max-line-len</code> (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.
-
-</li>
-<li>
-<code>--reserved-names</code> — 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>$super</code>
-intact you'd specify –reserved-names "require,$super".
-
-</li>
-<li>
-<code>--inline-script</code> – when you want to include the output literally in an
-HTML <code><script></code> tag you can use this option to prevent <code></script</code> from
-showing up in the output.
-</li>
-</ul>

-<div class="outline-text-4" id="text-1_4_1">
-
-
-<p>
-To use the library from JavaScript, you'd do the following (example for
-NodeJS):
-</p>
-
-
-
-<pre class="src src-js"><span style="color: #8b0000;">var</span> <span style="color: #8b008b;">jsp</span> = require(<span style="color: #008b00;">"uglify-js"</span>).parser;
-<span style="color: #8b0000;">var</span> <span style="color: #8b008b;">pro</span> = require(<span style="color: #008b00;">"uglify-js"</span>).uglify;
-
-<span style="color: #8b0000;">var</span> <span style="color: #8b008b;">orig_code</span> = <span style="color: #008b00;">"... JS code here"</span>;
-<span style="color: #8b0000;">var</span> <span style="color: #8b008b;">ast</span> = jsp.parse(orig_code); <span style="color: #00008b;">// </span><span style="color: #00008b;">parse code and get the initial AST
-</span>ast = pro.ast_mangle(ast); <span style="color: #00008b;">// </span><span style="color: #00008b;">get a new AST with mangled names
-</span>ast = pro.ast_squeeze(ast); <span style="color: #00008b;">// </span><span style="color: #00008b;">get an AST with compression optimizations
-</span><span style="color: #8b0000;">var</span> <span style="color: #8b008b;">final_code</span> = pro.gen_code(ast); <span style="color: #00008b;">// </span><span style="color: #00008b;">compressed code here
-</span></pre>
-
-
-
-<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> – 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> – generates a new AST containing mangled
-(compressed) variable and function names. It supports the following
-options:
-
-<ul>
-<li>
-<code>toplevel</code> – mangle toplevel names (by default we don't touch them).
-</li>
-<li>
-<code>except</code> – an array of names to exclude from compression.
-
-</li>
-</ul>
-</li>
-<li>
-<code>pro.ast_squeeze(ast, options)</code> – 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>

-<li>
-<code>pro.gen_code(ast, options)</code> – 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> – 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>) – 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> – 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>) – wether
-to put a space before the colon in object literals
-</li>
-<li>
-<code>ascii_only: false</code> – pass <code>true</code> if you want to encode non-ASCII
-characters as <code>\uXXXX</code>.
-</li>
-<li>
-<code>inline_script: false</code> – pass <code>true</code> to escape occurrences of
-<code></script</code> in strings
-</li>
-</ul>

-UglifyJS is the fastest to run. On my laptop UglifyJS takes 1.35s for

-<p>
-GoogleClosure does a lot of smart ass optimizations. I had to strive really

-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> – it just dumps a warning and proceeds to
-mangle names anyway; my DynarchLIB compiled with it is buggy because of
-this.

-<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

-Unfortunately, for the time being there is no automated test suite. But I

-<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,

-#+KEYWORDS: javascript, js, parser, compiler, compressor, mangle, minify, minifier
-#+DESCRIPTION: a JavaScript parser/compressor/beautifier in JavaScript
-#+STYLE: <link rel="stylesheet" type="text/css" href="docstyle.css" />
-#+AUTHOR: Mihai Bazon
-#+EMAIL: mihai.bazon@gmail.com
-
-* UglifyJS --- a JavaScript parser/compressor/beautifier
-
-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 js
-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 js
-// 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);
- })();
-
- // or
- (function(){
- return new Array(1, 2, 3, 4);
- function Array() { ... }
- })();
-
- // etc.
-#+END_SRC
-
-** Install (NPM)
-
-UglifyJS is now available through NPM --- =npm install uglify-js= should do
-the job.
-
-** Install latest code from GitHub
-
-#+BEGIN_SRC sh
-## clone the repository
-mkdir -p /where/you/wanna/put/it
-cd /where/you/wanna/put/it
-git clone git://github.com/mishoo/UglifyJS.git
-
-## make the module available to Node
-mkdir -p ~/.node_libraries/
-cd ~/.node_libraries/
-ln -s /where/you/wanna/put/it/UglifyJS/uglify-js.js
-
-## and if you want the CLI script too:
-mkdir -p ~/bin
-cd ~/bin
-ln -s /where/you/wanna/put/it/UglifyJS/bin/uglifyjs
- # (then add ~/bin to your $PATH if it's not there already)
-#+END_SRC
-
-** Usage
-
-There is a command-line tool that exposes the functionality of this library
-for your shell-scripting needs:
-
-#+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".
-
-- =--inline-script= -- when you want to include the output literally in an
- HTML =<script>= tag you can use this option to prevent =</script= from
- showing up in the output.
-
-*** API
-
-To use the library from JavaScript, you'd do the following (example for
-NodeJS):
-
-#+BEGIN_SRC js
-var jsp = require("uglify-js").parser;
-var pro = require("uglify-js").uglify;
-
-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=.
- - =inline_script: false= -- pass =true= to escape occurrences of
- =</script= in strings
-
-*** 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:

-| 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.

-/***********************************************************************
-
- 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.

# Jade - template engine
Jade is a high performance template engine heavily influenced by [Haml](http://haml-lang.com)
- combine dynamic and static tag classes
- parse tree manipulation via _filters_
- supports [Express JS](http://expressjs.com) out of the box
- - transparent iteration over objects, arrays, and even non-enumerables via `- each`
+ - transparent iteration over objects, arrays, and even non-enumerables via `each`
- block comments
- no tag prefix
- AST filters
$ make jade.js
- Alternatively, if uglifyjs is installed via npm (`npm install uglify-js`) you may execute the following which will create both files.
+ Alternatively, if uglifyjs is installed via npm (`npm install uglify-js`) you may execute the following which will create both files. However each release builds these for you.
$ make jade.min.js
+ By default Jade instruments templates with line number statements such as `__.lineno = 3` for debugging purposes. When used in a browser it's useful to minimize this boiler plate, you can do so by passing the option `{ compileDebug: false }`. The following template
+
+ p Hello #{name}
+
+ Can then be as small as the following generated function:
+
+```js
+function anonymous(locals, attrs, escape, rethrow) {
+ var buf = [];
+ with (locals || {}) {
+ var interp;
+ buf.push('\n<p>Hello ' + escape((interp = name) == null ? '' : interp) + '\n</p>');
+ }
+ return buf.join("");
+}
+```
+
+ Through the use of Jade's `./runtime.js` you may utilize these pre-compiled templates on the client-side _without_ Jade itself, all you need is the associated utility functions (in runtime.js), which are then available as `jade.attrs`, `jade.escape` etc. To enable this you should pass `{ client: true }` to `jade.compile()` to tell Jade to reference the helper functions
+ via `jade.attrs`, `jade.escape` etc.
+
+```js
+function anonymous(locals, attrs, escape, rethrow) {
+ var attrs = jade.attrs, escape = jade.escape, rethrow = jade.rethrow;
+ var buf = [];
+ with (locals || {}) {
+ var interp;
+ buf.push('\n<p>Hello ' + escape((interp = name) == null ? '' : interp) + '\n</p>');
+ }
+ return buf.join("");
+}
+```
+
## Public API
```javascript
var jade = require('jade');
- // Render a string
- jade.render('string of jade', { options: 'here' });
-
- // Render a file
- jade.renderFile('path/to/some.jade', { options: 'here' }, function(err, html){
- // options are optional,
- // the callback can be the second arg
- });
-
// Compile a function
var fn = jade.compile('string of jade', options);
- fn.call(scope, locals);
+ fn(locals);
```
### Options
- - `scope` Evaluation scope (`this`)
- `self` Use a `self` namespace to hold the locals. _false by default_
- `locals` Local variable object
- `filename` Used in exceptions, and required when using includes
- `debug` Outputs tokens and function body generated
- `compiler` Compiler to replace jade's default
+ - `compileDebug` When `false` no debug instrumentation is compiled
## Syntax
renders `<p>foo bar baz rawr.....</p>`
interpolation? yup! both types of text can utilize interpolation,
-if we passed `{ locals: { name: 'tj', email: 'tj@vision-media.ca' }}` to `render()`
-we can do the following:
+if we passed `{ name: 'tj', email: 'tj@vision-media.ca' }` to the compiled function we can do the following:
#user #{name} <#{email}>
<p>.</p>
+
+It should be noted that text blocks should be doubled escaped. For example if you desire the following output.
+
+ </p>foo\bar</p>
+
+use:
+
+ p.
+ foo\\bar
+
### Comments
Single line comments currently look the same as JavaScript comments,
a(href='/login', title='View login page') Login
+When a value is `undefined` or `null` the attribute is _not_ added,
+so this is fine, it will not compile 'something="null"'.
+
+ div(something=null)
+
Boolean attributes are also supported:
input(type="checkbox", checked)
Boolean attributes with code will only output the attribute when `true`:
- input(type="checkbox", checked= someValue)
+ input(type="checkbox", checked=someValue)
Multiple lines work too:
a(href='/user/' + user.id)= user.name
-or we could use jade's interpolation:
+or we could use jade's interpolation, which I added because everyone
+using Ruby or CoffeeScript seems to think this is legal js..:
a(href='/user/#{user.id}')= user.name
body(class=bodyClasses)
+### HTML
+
+ Inline html is fine, we can use the pipe syntax to
+ write arbitrary text, in this case some html:
+
+```
+html
+ body
+ | <h1>Title</h1>
+ | <p>foo bar baz</p>
+```
+
+ Or we can use the trailing `.` to indicate to Jade that we
+ only want text in this block, allowing us to omit the pipes:
+
+```
+html
+ body.
+ <h1>Title</h1>
+ <p>foo bar baz</p>
+```
+
+ Both of these examples yield the same result:
+
+```
+<html><body><h1>Title</h1>
+<p>foo bar baz</p>
+</body></html>
+```
+
+ The same rule applies for anywhere you can have text
+ in jade, raw html is fine:
+
+```
+html
+ body
+ h1 User <em>#{name}</em>
+```
+
### Doctypes
To add a doctype simply use `!!!`, or `doctype` followed by an optional value:
p!= aVarContainingMoreHTML
-The on exception made in terms of allowing "vanilla" JavaScript, is
-the `- each` token. This takes the form of:
+## Iteration
- - each VAL[, KEY] in OBJ
+ Along with vanilla JavaScript Jade also supports a subset of
+ constructs that allow you to create more designer-friendly templates,
+ one of these constructs is `each`, taking the form:
+
+ each VAL[, KEY] in OBJ
An example iterating over an array:
- var items = ["one", "two", "three"]
- - each item in items
+ each item in items
li= item
outputs:
<li>two</li>
<li>three</li>
+iterating an array with index:
+
+ - var items = ["one", "two", "three"]
+ each item, i in items
+ li #{item}: #{i}
+
+outputs:
+
+ <li>one: 0</li>
+ <li>two: 1</li>
+ <li>three: 2</li>
+
iterating an object's keys and values:
- var obj = { foo: 'bar' }
- - each val, key in obj
+ each val, key in obj
li #{key}: #{val}
would output `<li>foo: bar</li>`
-You can also nest these!
+Internally Jade converts these statements to regular
+JavaScript loops such as `users.forEach(function(user){`,
+so lexical scope and nesting applies as it would with regular
+JavaScript:
- - each user in users
- - each role in user.roles
+ each user in users
+ each role in user.roles
li= role
-When a property is undefined, Jade will output an empty string. For example:
+ You may also use `for` if you prefer:
+
+ for user in users
+ for role in user.roles
+ li= role
+
+## Conditionals
+
+ Jade conditionals are equivalent to those using the code (`-`) prefix,
+ however allow you to ditch parenthesis to become more designer friendly,
+ however keep in mind the expression given is _regular_ JavaScript:
- textarea= user.signature
+ for user in users
+ if user.role == 'admin'
+ p #{user.name} is an admin
+ else
+ p= user.name
-when undefined would normally output "undefined" in your html, however recent
-versions of Jade will simply render:
+ is equivalent to the following using vanilla JavaScript literals:
- <textarea></textarea>
+ for user in users
+ - if (user.role == 'admin')
+ p #{user.name} is an admin
+ - else
+ p= user.name
+
+ Jade also provides have `unless` which is equivalent to `if (!(expr))`:
+
+ for user in users
+ unless user.isAnonymous
+ p
+ | Click to view
+ a(href='/users/' + user.id)= user.name
## Includes
both includes _includes/head_ and _includes/foot_ are
read relative to the `filename` option given to _layout.jade_,
-which should be an absolute path to this file, however Express
-and the `renderFile()` method do this for you. Include then parses
-these files, and injects the AST produced to render what you would expect:
+which should be an absolute path to this file, however Express does this for you. Include then parses these files, and injects the AST produced to render what you would expect:

</div>
```
-## bin/jade
+## Generated Output
+
+ Suppose we have the following Jade:
+
+```
+- var title = 'yay'
+h1.title #{title}
+p Just an example
+```
+
+ When the `compileDebug` option is not explicitly `false`, Jade
+ will compile the function instrumented with `__.lineno = n;`, which
+ in the event of an exception is passed to `rethrow()` which constructs
+ a useful message relative to the initial Jade input.
+
+```js
+function anonymous(locals) {
+ var __ = { lineno: 1, input: "- var title = 'yay'\nh1.title #{title}\np Just an example", filename: "testing/test.js" };
+ var rethrow = jade.rethrow;
+ try {
+ var attrs = jade.attrs, escape = jade.escape;
+ var buf = [];
+ with (locals || {}) {
+ var interp;
+ __.lineno = 1;
+ var title = 'yay'
+ __.lineno = 2;
+ buf.push('<h1');
+ buf.push(attrs({ "class": ('title') }));
+ buf.push('>');
+ buf.push('' + escape((interp = title) == null ? '' : interp) + '');
+ buf.push('</h1>');
+ __.lineno = 3;
+ buf.push('<p>');
+ buf.push('Just an example');
+ buf.push('</p>');
+ }
+ return buf.join("");
+ } catch (err) {
+ rethrow(err, __.input, __.filename, __.lineno);
+ }
+}
+```
+
+When the `compileDebug` option _is_ explicitly `false`, this instrumentation
+is stripped, which is very helpful for light-weight client-side templates. Combining Jade's options with the `./runtime.js` file in this repo allows you
+to toString() compiled templates and avoid running the entire Jade library on
+the client, increasing performance, and decreasing the amount of JavaScript
+required.
+
+```js
+function anonymous(locals) {
+ var attrs = jade.attrs, escape = jade.escape;
+ var buf = [];
+ with (locals || {}) {
+ var interp;
+ var title = 'yay'
+ buf.push('<h1');
+ buf.push(attrs({ "class": ('title') }));
+ buf.push('>');
+ buf.push('' + escape((interp = title) == null ? '' : interp) + '');
+ buf.push('</h1>');
+ buf.push('<p>');
+ buf.push('Just an example');
+ buf.push('</p>');
+ }
+ return buf.join("");
+}
+```
-Output html to _stdout_:
+## Example Makefile
- jade < my.jade > my.html
+ Below is an example Makefile used to compile _pages/*.jade_
+ into _pages/*.html_ files by simply executing `make`.
+
+```make
+JADE = $(shell find pages/*.jade)
+HTML = $(JADE:.jade=.html)
-Generate _examples/*.html_:
+all: $(HTML)
+
+%.html: %.jade
+ jade < $< > $@
- jade examples/*.jade
+clean:
+ rm -f $(HTML)
+
+.PHONY: clean
+```
-Pass options:
+this can be combined with the `watch(1)` command to produce
+a watcher-like behaviour:
+
+ $ watch make
+
+## jade(1)
+
+```
- jade examples/layout.jade --options '{ locals: { title: "foo" }}'
+Usage: jade [options] [dir|file ...]
-Usage info:

-# EJS
-
-Embedded JavaScript templates.
-
-## Installation
-
- $ npm install ejs
-
-## Features
-
- * Complies with the [Express](http://expressjs.com) view system
- * Static caching of intermediate JavaScript
- * Unbuffered code for conditionals etc `<% code %>`
- * Escapes html by default with `<%= code %>`
- * Unescaped buffering with `<%- code %>`
- * Supports tag customization
- * Filter support for designer-friendly templates
-
-## Example
-
- <% if (user) { %>
- <h2><%= user.name %></h2>
- <% } %>
-
-## Usage
-
- ejs.compile(str, options);
- // => Function
-
- ejs.render(str, options);
- // => str
-
-## Options
-
- - `locals` Local variables object
- - `cache` Compiled functions are cached, requires `filename`
- - `filename` Used by `cache` to key caches
- - `scope` Function execution context
- - `debug` Output generated function body
- - `open` Open tag, defaulting to "<%"
- - `close` Closing tag, defaulting to "%>"
-
-## Custom Tags
-
-Custom tags can also be applied globally:
-
- var ejs = require('ejs');
- ejs.open = '{{';
- ejs.close = '}}';
-
-Which would make the following a valid template:
-
- <h1>{{= title }}</h1>
-
-## Filters
-
-EJS conditionally supports the concept of "filters". A "filter chain"
-is a designer friendly api for manipulating data, without writing JavaScript.
-
-Filters can be applied by supplying the _:_ modifier, so for example if we wish to take the array `[{ name: 'tj' }, { name: 'mape' }, { name: 'guillermo' }]` and output a list of names we can do this simply with filters:
-
-Template:
-
- <p><%=: users | map:'name' | join %></p>
-
-Output:
-
- <p>Tj, Mape, Guillermo</p>
-
-Render call:
-
- ejs.render(str, {
- locals: {
- users: [
- { name: 'tj' },
- { name: 'mape' },
- { name: 'guillermo' }
- ]
- }
- });
-
-Or perhaps capitalize the first user's name for display:
-
- <p><%=: users | first | capitalize %></p>
-
-## Filter List
-
-Currently these filters are available:
-
- - first
- - last
- - capitalize
- - downcase
- - upcase
- - sort
- - sort_by:'prop'
- - size
- - length
- - plus:n
- - minus:n
- - times:n
- - divided_by:n
- - join:'val'
- - truncate:n
- - truncate_words:n
- - replace:pattern,substitution
- - prepend:val
- - append:val
- - map:'prop'
- - reverse
- - get:'prop'

-# HAML-JS Changelog
-
-- **v0.2.5** - *2010-05-06* - NPM support
-
- Fixed to work with Node Package Manager
-
-- **v0.2.4** - *2010-04-16* - Bug fixes, XML support
-
- Allow for commas in calls to helpers in attributes. Also make haml more XML friendly.
-
-- **v0.2.3** - *2010-04-10* - Bug fixes
-
- Fixed an issue where "content" html attributes got munched. (This broke meta tags)
-
-- **v0.2.2** - *2010-04-05* - Bug fixes
-
- Fixed two issues where the parser incorrectly parsed blank lines and extra spaces in attribute blocks.
-
-- **v0.2.1** - *2010-04-01* - Minor speed tweak
-
- `Haml()` now caches the eval step so that there is no eval in executing a compiled template. This should make things a bit faster.
-
-- **v0.2.0** - *2010-03-31* - Function based API, Safe whitespace, Code interpolation.
-
- At the request of some users, I've removed the new insertion into the generated html. This means that most html will be on one long line, but as an added advantage you won't have that extra whitespace next to your anchor labels messing up your visual display.
-
- Also I added string interpolation to every place I could fit it. This means you can do crazy stuff like interpolate within strings in attributes, in the body on plain text sections, and of course in javascript and css plugin blocks.
-
- In order to tame the API, I deprecated the four old interfaces `compile`, `optimize`, `execute` and `render`. The new API is that the Haml/exports object itself is now a function that takes in haml text and outputs a compiled, optimized, ready to execute function.
-
-- **0.1.2** - *2010-02-03* - Bug fixes, plugin aliases, CommonJS, and more...
-
- This is a big release with many improvements. First haml-js is now a CommonJS module and is in the Tusk repository. Thanks to Tom Robinson for helping with that. Some of the plugins got aliases for people who didn't like the original name. For example, you can now do `:javascript` instead of `:script` and `:for` instead of `:each`. There were many bug fixes now that the code is starting to be actually used by myself and others.
-
-- **0.1.1** - *2010-01-09* - Add :css and :script plugins
-
- Added two quick plugins that make working with javascript and css much easier.
-
- - **0.1.0** - *2010-01-09* - Complete Rewrite
-
- Rewrote the compiler to be recursive and compile to JavaScript code instead of JSON data structures. This fixes all the outstanding bugs and simplifies the code. Pending is restoring the `:script` and `:css` plugins.
-
- - **0.0.1** - *2009-12-16* - Initial release
-
- Change how haml is packaged. It is a pure JS function with no node dependencies. There is an exports hook for commonjs usability. It's now the responsibility of the script user to acquire the haml text.

-# haml-js - Server side templating language for JavaScript
-
-Ever wanted to use the excellent HAML syntax on a javascript project? Me too, so I made one!. This has most of the same functionality as the traditional [haml][].
-
-## About the language
-
-Here is the first example(with a little extra added) from the [haml][] site converted to haml-js:
-
-**haml-js**
-
- !!! XML
- !!! strict
- %html{ xmlns: "http://www.w3.org/1999/xhtml" }
- %head
- %title Sample haml template
- %body
- .profile
- .left.column
- #date= print_date()
- #address= current_user.address
- .right.column
- #email= current_user.email
- #bio= current_user.bio
-
-**html**
-
- <?xml version='1.0' encoding='utf-8' ?>
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
- <html xmlns="http://www.w3.org/1999/xhtml"><head><title>Sample haml template
- </title></head><body><div class="profile"><div class="left column"><div id="date">January 1, 2009
- </div><div id="address">Richardson, TX
- </div></div><div class="right column"><div id="email">tim@creationix.com
- </div><div id="bio">Experienced software professional...
- </div></div></div></body></html>
-
-Note that this works almost the same as ruby's [haml][], but doesn't pretty print the html. This would greatly slow down and complicate the code. If you really want pretty printed html, then I suggest writing one using the xml parser library and process the resulting html..
-
-## API
-
-### Haml(haml) -> template(locals) -> html
-
-This is the new (as of 0.2.0) way to generate haml templates. A haml template is a live function that takes in "this" context and a "locals" variable. This compile step takes a few milliseconds to complete so it should be done at startup and the resulting function should be cached. Then to use the template function you simply call it with the desired local variables and it will output html at blazing speeds (we're talking millions per second on my 13" MBP)
-
-Compile and store a template:
-
- var main = Haml(main_haml);
-
-Then use it whenever you need a new version:
-
- main({name: "Tim", age: 28});
-
-That's it. Haml templating made easy!
-
-If you want to store the generated javascript to a file to skip the compile step later on you can either decompile the template function or use the `compile` and `optimize` advanced functions directly.
-
-
-### Haml.compile(text) -> JavaScript compiled template
-
-Given a haml template as raw text, this compiles it to a javascript expression
-that can later be eval'ed to get the final HTML.
-
-The following input:
-
- #home
- = title
- %ul.menu
- %li Go Home
- %li Go Back
-
-Produces the following JavaScript expression:
-
- "<div id=\"home\">" +
- title +
- "\n" +

-### Haml.optimize(js) -> optimized JavaScript expression
-
-Takes the output of compile and optimizes it to run faster with the tradeoff of longer compile time. This is useful for framework developers wanting to use haml in their framework and want to cache the compiled templates for performance.
-
-With the previous input it outputs:
-
- "<div id=\"home\">" +
- title +
- "\n<ul class=\"menu\"><li>Go Home\n</li><li>Go Back\n</li></ul></div>"
-
-Notice how congruent static strings are merged into a single string literal when possible.
-
-### Haml.execute(js, context, locals) -> Executes a compiles template
-
-Context is the value of `this` in the template, and locals is a hash of local variables.
-
-### Haml.render(text, options) -> html text
-
-This is a convenience function that compiles and executes to html in one shot. Most casual users will want to use this function exclusively.
-
-The `text` parameter is the haml source already read from a file.
-
-The three recognized `options` are:
-
- - **context**: This is the `this` context within the haml template.
- - **locals**: This is an object that's used in the `with` scope. Basically it creates local variables and function accessible to the haml template.
- - **optimize**: This is a flag to tell the compiler to use the extra optimizations.
-
-See [test.js][] for an example usage of Haml.render
-
-## Code interpolation
-
-New in version 0.2.0 there is string interpolation throughout. This means that the body of regular text areas can have embedded code. This is true for attributes and the contents of plugins like javascript and markdown also. If you notice an area that doesn't support interpolation and it should then send me a note and I'll add it.
-
-## Plugins
-
-There are plugins in the parser for things like inline script tags, css blocks, and support for if statements and for loops.
-
-### `:if` statements
-
-`if` statements evaluate a condition for truthiness (as opposed to a strict comparison to `true`) and includes the content inside the block if it's truthy.
-
- :if todolist.length > 20
- %p Oh my, you are a busy fellow!
-
-### `:each` loops
-
-`:each` loops allow you to loop over a collection including a block of content once for each item. You need to what variable to pull the data from and where to put the index and value. The index variable is optional and defaults to `__key__`.
-
-Here is an example over a simple array.
-
- %ul.todolist
- :each item in todolist
- %li= item.description
-
-You can loop over the keys and values of objects too (Note the inner `:each` loop)
-
- :each item in data
- :if item.age < 100
- %dl
- :each name, value in item
- %dt&= name
- %dd&= value
-
-### `:css` and `:javascript` helpers.
-
-It's easy to embed javascript and css blocks in an haml document.
-
- %head
- :javascript
- function greet(message) {
- alert("Message from MCP: " + message);
- }
- %title Script and Css test
- :css
- body {
- color: pink;
- }
- %body{ onload: "greet(\"I'm Pink\")" } COLOR ME PINK
-
-This compiles to the following HTML:
-
- <head>
- <script type="text/javascript">
- //<![CDATA[
- function greet(message) {
- alert("Message from MCP: " + message);
- }
- //]]>
- </script>
- <title>Script and Css test
- </title>
- <style type="text/css">
- body {
- color: pink;
- }
- </style>
- </head><body onload="greet("I'm Pink")"> COLOR ME PINK
- </body>
-
-## Get Involved
-
-If you want to use this project and something is missing then send me a message. I'm very busy and have several open source projects I manage. I'll contribute to this project as I have time, but if there is more interest for some particular aspect, I'll work on it a lot faster. Also you're welcome to fork this project and send me patches/pull-requests.
-
-## About Performance
-
-The haml compiler isn't built for speed, it's built for maintainability. The actual generated templates, however are blazing fast. I benchmarked them with over 65 million renders per second on a small (20 line) template with some dynamic data on my laptop. Compare this to the 629 compiles per second I got out of the compiler. The idea is that you pre-compile your templates and reuse them on every request. While 629 per second is nothing compared to 65 million, that still means that your server with over 600 different views can boot up in about a second. I think that's fine for something that only happens every few weeks.

-# Haml.js
-
- High performance JavaScript [Haml](http://haml-lang.com) implementation for [nodejs](http://nodejs.org)
-
- For a higher quality implementation you may want to look at my [Jade](http://jade-lang.com) template engine,
- however the syntax is slightly different. Jade's engine may be back-ported to haml.js in the future.
-
-## Installation
-
- Install the [Kiwi package manager for nodejs](http://github.com/visionmedia/kiwi)
- and run:
-
- $ kiwi install haml
-
- node> require('haml')
-
-Or npm:
-
- $ npm install hamljs
-
- node> require('hamljs')
-
-## About
-
- Benchmarks rendering the same 21 line haml file located at _benchmarks/page.haml_,
- shows that this library is nearly **65%** or **3 times** faster than haml-js.
-
- Winner: haml.js
- Compared with next highest (haml-js), it's:
- 65.39% faster
- 2.89 times as fast
- 0 order(s) of magnitude faster
-
- Haml.js attempts to comply with the original [Haml](http://haml-lang.com/docs/yardoc/file.HAML_REFERENCE.html)
- implementation as well as possible. There are no magic "plugins" like
- found in other JavaScript haml implementations, for example the following
- will work just fine:
-
- - if (items)
- %ul
- - for (var i = 0; i < items.length; ++i)
- %li= items[i]
-
- Iteration is the one exception to these magical plugins,
- since this is **ugly** in JavaScript, you may also:
-
- - if (items)
- %ul
- - each item in items
- %li= item
-
-## Usage
-
- var haml = require('haml')
- haml.render('a string of haml', { a: 'hash', of: 'options' })
-
-## Options
-
- * context
- - when passed the value of "this" becomes the given "context" object
- * locals
- - when passed all members of this object become available to this template
- * filename
- - required when _cache_ is enabled
- * cache
- - compiled intermediate javascript is cached in memory keyed by _filename_
-
-## Tags
-
- %div text
-
-html:
-
- <div>text</div>
-
-## Classes
-
- %div.article.first
- article text here
- and here
-
-html:
-
- <div class="article first">
- article text here and here
- </div>
-
-## Div Class Shortcut
-
- .comment hey
-
-html:
-
- <div class="comment">hey</div>
-
-## Div Id Shortcut
-
- #article-1 foo
-
-html:
-
- <div id="article-1">foo</div>
-
-## Combining Ids and Classes
-
-You may chain id and classes in any order:
-
- .article#first.summary content
-
-html:
-
- <div id="first" class="article summary">context</div>
-
-## Attributes
-
- %a{ href: 'http://google.com', title: 'Google It' } Google
-
-html:
-
- <a href="http://google.com" title="Google It">Google</a>
-
-Attribute keys such as "for" are automatically quoted
-by haml.js, so instead of:
-
- %label{ 'for': 'something' }
-
-you should:
-
- %label{ for: 'something' }
-
-which will render:
-
- <label for="something"></label>
-
-## Boolean Attributes
-
- %input{ type: 'checkbox', checked: true }
-
-html:
-
- <input type="checkbox" checked="checked"/>
-
-## Combining Attributes, Ids, and Classes
-
-Wemay also contain id and classes before or after:
-
- %a.button{ href: 'http://google.com', title: 'Google It' }.first Google
-
-html:
-
- <a href="http://google.com" title="Google It" class="button first">Google</a>
-
-## Code
-
-Code starting with a hyphen will be executed but
-not buffered, where as code using the equals sign
-will be buffered:
-
- - a = 1
- - b = 2
- = a + b
-
-html:
-
- 3
-
-HTML buffered with equals sign will **always** be escaped:
-
- = "<br/>"
-
-html:
-
- <br/>
-
-To prevent escaping of HTML entities we can use _!=_:
-
- != "<br/>"
-
-html:
-
- <br/>
-
-## Iteration
-
- %ul
- - each item in items
- %li= item
-
-html:
-
- <ul>
- <li>one</li>
- <li>two</li>
- <li>three</li>
- </ul>
-
-If you require the key or index of the object
-or array during iteration simple append a comma
-following another id:
-
- %ul
- - each item, index in items
- %li= item + '(' + index + ')'
-
-html:
-
- <ul>
- <li>one(0)</li>
- <li>two(1)</li>
- <li>three(2)</li>
- </ul>
-
-## Doctypes
-
-Defaults to transitional:
-
- !!!
-
-html:
-
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
-
-Optionally pass a supported doctype name:
-
- !!! strict
-
-html:
-
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
-
-currently supported doctypes, which can be
-extended simply by adding values to to _haml.doctypes_.
-
- '5': '<!DOCTYPE html>',
- 'xml': '<?xml version="1.0" encoding="utf-8" ?>',
- 'default': '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">',
- 'strict': '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">',
- 'frameset': '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">',
- '1.1': '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">',
- 'basic': '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML Basic 1.1//EN" "http://www.w3.org/TR/xhtml-basic/xhtml-basic11.dtd">',

-## Extending Haml
-
-### Adding Filters
-
- var haml = require('haml')
- haml.filters.my_filter = function(str) {
- return doSomethingWith(str)
- }
-
-by registering the filter function _my_filter_ we can now
-utilize it within our Haml templates as shown below:
- %p
- :my_filter
- some text
- here yay
- whoop awesome
-
-### Adding Doctypes
-
- var haml = require('haml')
- haml.doctypes.foo = '<!DOCTYPE ... >'
-
-Will now allow you to:
- !!! foo
-
-## Running Benchmarks
-
-To run benchmarks against [haml-js](http://github.com/creationix/haml-js)
-simply execute:
-
- $ git submodule update --init
- $ node benchmarks/run.js
-

+A prototype [Web Socket](http://www.whatwg.org/specs/web-socket-protocol/)
+client implementation for [node.js](http://nodejs.org).
+
+Tested with
+[miksago/node-websocket-server](http://github.com/miksago/node-websocket-server)
+v1.2.00.
+
+Requires [nodejs](http://nodejs.org) 0.1.98 or later.
+
+## Installation
+
+Install this using `npm` as follows
+
+ npm install websocket-client
+
+... or just dump `lib/websocket.js` in your `$NODE_PATH`.
+
+## Usage
+
+ var sys = require('sys');
+ var WebSocket = require('websocket').WebSocket;
+
+ var ws = new WebSocket('ws://localhost:8000/biff', 'borf');
+ ws.addListener('data', function(buf) {
+ sys.debug('Got data: ' + sys.inspect(buf));
+ });
+ ws.onmessage = function(m) {
+ sys.debug('Got message: ' + m);
+ }
+
+## API
+
+This supports the `send()` and `onmessage()` APIs. The `WebSocket` object will
+also emit `data` events that are node `Buffer` objects, in case you want to
+work with something lower-level than strings.
+
+## Transports
+
+Multiple transports are supported, indicated by the scheme provided to the
+`WebSocket` constructor. `ws://` is a standard TCP-based Web Socket;
+`ws+unix://` allows connection to a UNIX socket at the given path.

-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 can in theory break code, although they're
+probably safe in most practical cases. To enable them you need to pass the
+<code>--unsafe</code> flag.

-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> – 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>!

** <<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.
+The following transformations can in theory break code, although they're
+probably safe in most practical cases. To enable them you need to pass the
+=--unsafe= flag.
*** Calls involving the global Array constructor
// etc.
#+END_SRC
+*** =obj.toString()= ==> =obj+“”=
+
** Install (NPM)
UglifyJS is now available through NPM --- =npm install uglify-js= should do
- =-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:
HTML =<script>= tag you can use this option to prevent =</script= from
showing up in the output.
+- =--lift-vars= -- when you pass this, UglifyJS will apply the following
+ transformations (see the notes in API, =ast_lift_variables=):
+
+ - put all =var= declarations at the start of the scope
+ - make sure a variable is declared only once
+ - discard unused function arguments
+ - discard unused inner (named) functions
+ - finally, try to merge assignments into that one =var= declaration, if
+ possible.
+
*** API
To use the library from JavaScript, you'd do the following (example for
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_lift_variables(ast)= -- merge and move =var= declarations to the
+ scop of the scope; discard unused function arguments or variables; discard
+ unused (named) inner functions. It also tries to merge assignments
+ following the =var= declaration into it.
+
+ If your code is very hand-optimized concerning =var= declarations, this
+ lifting variable declarations might actually increase size. For me it
+ helps out. On jQuery it adds 865 bytes (243 after gzip). YMMV. Also
+ note that (since it's not enabled by default) this operation isn't yet
+ heavily tested (please report if you find issues!).
+
+ Note that although it might increase the image size (on jQuery it gains
+ 865 bytes, 243 after gzip) it's technically more correct: in certain
+ situations, dead code removal might drop variable declarations, which
+ would not happen if the variables are lifted in advance.
+
+ Here's an example of what it does:
+
+#+BEGIN_SRC js
+function f(a, b, c, d, e) {
+ var q;
+ var w;
+ w = 10;
+ q = 20;
+ for (var i = 1; i < 10; ++i) {
+ var boo = foo(a);
+ }
+ for (var i = 0; i < 1; ++i) {
+ var boo = bar(c);
+ }
+ function foo(){ ... }
+ function bar(){ ... }
+ function baz(){ ... }
+}
+
+// transforms into ==>

+function f(a, b, c) {
+ var i, boo, w = 10, q = 20;

-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.
+Here are updated statistics. (I also updated my Google Closure and YUI
+installations).
-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.
+We're still a lot better than YUI in terms of compression, though slightly
+slower. We're still a lot faster than Closure, and compression after gzip
+is comparable.
-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*!
