gulp-ifcompile

A conditional compling plugin for gulp. You can easily output two different codes for conditional with one source code.

一个用于实现条件编译的gulp插件。可以自行添加不同的条件，类似宏的预编译。

use

	npm install --save-dev gulp-ifcompile
	
	
	
	var ifcompile = require("ifcompile")
	
	gulp.task('pub', function () {
    		gulp.src(["build/Base64.js", "build/profiler/nativeProfiler.js"])
        	.pipe(ifcompile({isApp:true, isDebug:true}))
        	.pipe(concat("native.js"))
        	.pipe(gulp.dest('product/ios'));
        

Current condition

	condition = {
		isDebug:{begin:"IFDEBUG", end:"FIDEBUG"},
		isApp:{begin:"IFAPP", end:"FIAPP"},
		isH5:{begin:"IFH5", end:"FIH5"},
		isWeChat:{begin:"IFWECHAT", end:"FIWECHAT"}
	}

Usage in JS files Just use it like this:

	/*IFCONDITION Any js here FICONDITION*/

Start with "/IFCONDITION", end with"FICONDITION/", and js code in the center. you can use it any where in js files.

eg:

	$state.go('win', {dir: menu.winId /*IFCONDITION , reload: true FICONDITION*/})

or

	/* IFCONDITION
		alert('Hi~');
	FICONDITION*/

Since it is a comment style, the code can run normaly even though gulp-ifcompile is not processed.

因为是注释的形式，故即使不运行gulp-ifcompile，也不影响js代码的运行。

Config in gulp You should call this plugin before other js file processes, like this:

需要在js文件的其他处理过程之前调用此插件，像这样：

gulp.task('js', function () {
	return gulp.src(sources)
        .pipe($.ifcompile(  {isDebug: !isProduction, isApp: !isProduction}  ))
        ...pipe other processes...
});

options

isCondition: {bool = true}

If isCondition === false, all the codes between "/IFCONDITION" and "FICONDITION/" will be removed, otherwise the codes will be remained.

如果isDebug === false，所有"/IFCONDITION" 和 "IFCONDITION/"之间的代码都会被移除。 其他情况的isDebug，这些代码则会被保留。
