Jselocity

a velocity like javascript template engine

How to use

variable

var renderer = tmpl('fire in the $name!')
renderer.render({name: 'hole'}); //return 'fire in the hole!'

if statement

var s =	'						\
		#if($flag === "yes")	\n\
			you are right!		\n\
		#elseif($flag === "no")	\n\
			go die! 			\n\
		#else					\n\
			WTF!!				\n\
		#end					\n\
		';
tmpl(s).render({flag: 'true'}); //return 'WTF!!'

for statement

built-in variables: $INDEX $ODD $EVEN

var s = '							\
		#for($item in $items)		\n\
			day$INDEX, $item.did.	\n\
		#end						\n\
		';
var d = {
	list : [
		{weather: 'fine', did: 'sleep'},
		{weather: 'rainy', did: 'sleep'},
		{weather: 'cloudy', did: 'sleep'},
		{weather: 'fine', did: 'sleep'},
	]
};
tmpl(s).render(d);
/*	return
	day1, sleep.
	day2, sleep.
	day3, sleep.
	day4, sleep.
*/

format

tmpl.addFormat('time', function(v) { //add formatter first
	return new Date(v).toLocaleDateString();;
});

tmpl('#format.time($msec)').render({msec: 1356278400000}); //return 'Mon Dec 24 2012 00:00:00 GMT+0800'

TIPS

use '\0'

tmpl('$name\0DAM!!!').render({name: 'GUN'}); //return 'GUNDAM!!!';

there is no cache sys in jselocity, you should cache it by self.

var cache	= {},
	url 	= '/user/id',
	s		= getStringByURL(url);
	
var renderer = tmpl(s); //get it
cache[url] = renderer; //cache it
/* ===========> */
var rendererNow = cache[url]; //reget
var result = rendererNow.render(data); //output
