Kjscompiler

Makes compilation of multiple JavaScript files with Google Closure Compiler application in right order.

Goal is to convert layout at input:

In to minifed layout:

With respect to internal and external dependencies.

Requirements

Requires Java Runtime Environment version 7.

How to run

java -jar kjscompiler.jar

Kjscompiler.json

Instead of kjscompile.json you can specify your own path to configuration file with --settings %path% attribute.

basedir - directory or array of directories with JavaScript files;

output - output JavaScript file name;

pattern - rule for filename (*.js);

level - level of optimization (WHITESPACE_ONLY, SIMPLE_OPTIMIZATIONS, ADVANCED_OPTIMIZATIONS).

wrapper - setting to wrap your output. The place holder is "%output%".

Example:

{
	"basedir": "js",
	"output": "js.min/all.js",
	"level": "SIMPLE_OPTIMIZATIONS",
	"pattern": "*.js"
}

Example:

{
	"basedir": ["lib/javascript", "lib/ecmascript"],
	"output": "js.min/all.js",
	"level": "SIMPLE_OPTIMIZATIONS",
	"pattern": "*.js",
	"wrapper" : "(function(){ %output% }());"
}

Note: Any path will be relative to the settings file. If none provided it will be relative to the current working directory ( the directory where you launched kjscompiler ).

Annotating JavaScript files

Kjscompiler can use information about JavaScript file to build right compiling chain.

Tag	Example	Description
@depends	@depends {somescript.js}	Specifies dependency on other file.
@ignore	@ignore	File with this mark will be ignored.
@external	@external	File with this mark will be considered as external. It will not be compiled, but it will give no unknown variable error during the compilation.

/**
 * kjscompiler annotation
 * @depends {somescript}
 * @depends {dir/otherscript}
 */

/**
 * kjscompiler annotation
 * @ignore
 */

/**
 * kjscompiler annotation
 * @external
 */

Debug

To debug add --debug true in call line.
