/**
* 编译模板片段，并将模板片段放在name缓存文件中
* 模板文件中允许存在如下三种形式：
* <pre>
* 1、第一种：
* <hook-action name="hook1" args='a,b,c'>
* <div>i am from hook1 {$a} |{$b}|{$c}</div>
* </hook-action>
* 如上将会被编译成：
* function templateName_hook1($a, $b, $c){
* }
* 2、第二种：
* <hook-action name="hook2">
* <div> i am from hook2 {$data} </div>
* </hook-action>
* 如上将会编译成：
* function templateName_hook2($data){
* }
* 3、第三种：
* <div> i am from segment {$data}</div>
* 如上将会被编译成：
* function templateName($data) {
* }
*
* 模板标签：
* <segment alias='' name='' args='' tpl='' />
* tpl文件中的模板内容按照如上三种规则被编译之后，将会保存到__segment_alias文件中
* 调用方法根据：
* tpl_name来调用,如果func没有写，则调用方法为tpl，否则为tpl_func,传入参数为args
* </pre>
*
* @param string $template
* @param array $args
* @param string $func
* @param string $alias
* @param WindViewResolve $viewer
* @return
