ESC之ESC.wsf可以实现javascript的代码压缩附使用方法

人气:0
作用:可以对javascript的大小进行压缩。使javascript的加载速度变快。

用法:
在 cmd下面输入的东西;
cscript ESC.wsf -l 3 -ow ../global.js global.js

上面是一个简单的例子:可以自己建一个bat文件放在当前目录下面

cscript ESC.wsf -l 压缩级别 -ow 。。/要压缩到那个目录 需要进行压缩的原js
1.
Level 0 :: No compression //没有处里
Level 1 :: Comment removal //删除掉注释
Level 3 :: Newline removal //删除掉新行
Level 4 :: Variable substitution //变量的替换
2.下图时所用到的参数:
-l 级别
-s
-v
-$
-oa 以追加的形式覆盖
-ow 以覆盖的形式覆盖


所用压缩包在附件 还有帮助文档

使用的例子见压缩包中的图片。

Introduction 
ESC is an ECMAScript pre-processor written in JScript, enabling an unlimited number of external scripts to be compressed/crunched into supertight, bandwidth-optimized packages. Featuring several compression-techniques such as comment removal, whitespace stripping, newline stripping and variable substitution ESC can reduce the overall size of your code with up to ~45%. Single, multiple scripts and even directories with scripts can be merged together at the compression level you decide. The processed output can later be appended or written to a file, or piped to another application for further processing via STDOUT.      ESC do NOT support crunching of inline scripts. So any attempt passing HTML, ASP, JSP, PHP or other equivalent documents to ESC is done at your own risk.      ESC supports four levels of compression, where a higher level equals higher compression. Beware though that levels >2 requires your code to be syntaxically perfect or ESC will punish you by producing a broken and useless output.      The compression ratio should hit around 25% using the default compression level on a vanilla looking script, but results as high as ~45% can be achieved depending on the script's design / your style of writing code.      ESC's compression engine is intelligent in the meaning that it has language syntax, statement and keyword awareness and it *knows* about native objects and members provided by the most common scripting hosts. This knowledgebase can easily be extended by pluggin in userdefined maps with additional information to further gain control of the crunching procedure. During processing following things are taken into account :      String and RegExpression read-ahead 
JScript Conditional compilation statements and variables 
ECMA-262 Core language definitions (ECMAScript) 
Intermediate DOM's (level 0) and DOM level 1 
MS JScript specific objects/methods 
Netscape/Mozilla/Opera specific objects/methods/properties 
MS WSH (Windows Scripting Host) 1+ native objects  

Crunching, level by level   

Level 0 :: No compression 
No compression done. Basically a content transfer/append from input(s) to output. This level is mainly used for tracking down problems occuring to scripts after been shoved through the variable substitution engine.      

Level 1 :: Comment removal 
ESC removes empty lines (\r?\n)+, single and multi-line and single-line comments (//..., /* ... */) and trailing whitespace. [ \t]+\r?\n  

 
Level 2 :: Whitespace removal 
Any occurance of space and tabs (\s\t\r) are removed from the infile(s). This is the default compression-level if none is supplied.  

 
Level 3 :: Newline removal 
Newlines (\r?\n) are removed. ESC do not like sloppy written code and will at this level punish you for it by producing a very tight, human unreadable, uninpretable chunk o' chars :) So remember, *ALWAYS* terminate your statements with semi-colons (';'). If you come from a C/C++ bg you have probably been taught this the hard way by an evercroaking compiler. If not for getting your script thru ESC, so start doing it anyway for good ol' programming style.  

 
Level 4 :: Variable substitution 
(variable substitution mode, identical to options '-l 3 -$') Additionally to level 3, ESC will run your script(s) through the variable substitution engine. This will certainly break your scripts at the first try, but with a little fiddling around and once you understand how the substitution scheme works, this thing rule since it will save you another extra 5-20% bytewise depending on your coding style. Variable-names less than 3 chars are not affected. Before you try running ESC with variable substitution enabled, I advice you to carefully read the other sections in this manual about the pros and cons, thinking session-dependencies and the known caveats of variable crunching with ESC. Your specific situation in terms of namespaces, shared variables or the design/architecture of your scripts may make it difficult, even impossible to combine with this technique whereas you'll have to stick with level 3.  


Commandline options
There are a set of options available to provide full control of how you want your source files treated. This list is also available by running ESC with the -help option, but I'll try to explain some of them here more indepth.
 
  • -l (level) Sets the crunch-level you wish to use in the range of 0-4. If this option is not set, level 2 is assumed.
  • -s (silent) Produce no report and no error messages whatsoever.
  • -v (verbose) When verbose mode is enabled, ESC will echo every action performed back to the console. This comes in handy when debugging or if you just want to view the process taking place. By using > you can even pipe the verbosed output to a logfile or similar. Ex. cscript ESC.wsf -v -ow all.js C:\script-dir > verbose.log
  • -$ This option explicitly instructs ESC to activate the variable-substitution engine. The substition engine is the man doing the dirtywork at level 4, responsible for the most complex part of the crunching process, but by using this option ESC can be told to use it on lower levels also. For instance, using the option-combo -l 0 -$ would leave your scripts unprocessed in terms of whitespace and comments, but any variable-name not recognized as blessed will be mangled within a global scope.
  • -oa <filename> With this directive you are telling ESC to append the crunched data to the file specified. If the specified file doesn't exist, ESC will create it.
  • -ow <filename> | STDOUT Same as with -ao, but with the difference that ESC will write the output to the file specified instead of appending. This option will cause any previous file with the same name to be overwritten, so be careful. Optionally you can instruct ESC to write the stream to STDOUT instead of a file. Comes in handy if you are piping the output to another process.
