|
* @namespace TemplateLoader
|
|
* @description Swig is able to accept custom template loaders written by you, so that your templates can come from your favorite storage medium without needing to be part of the core library.
|
|
* A template loader consists of two methods: <var>resolve</var> and <var>load</var>. Each method is used internally by Swig to find and load the source of the template before attempting to parse and compile it.
|
|
* @example
|
|
* // A theoretical memcached loader
|
|
* var path = require('path'),
|
|
* Memcached = require('memcached');
|
|
* function memcachedLoader(locations, options) {
|
|
* var memcached = new Memcached(locations, options);
|
|
* return {
|
|
* resolve: function (to, from) {
|
|
* return path.resolve(from, to);
|
|
* },
|
|
* load: function (identifier, cb) {
|
|
* memcached.get(identifier, function (err, data) {
|
|
* // if (!data) { load from filesystem; }
|
|
* cb(err, data);
|
|
* });
|
|
* }
|
|
* };
|
|
* };
|
|
* // Tell swig about the loader:
|
|
* swig.setDefaults({ loader: memcachedLoader(['192.168.0.2']) });
