JAPE语法规则

Question

我是GATE，JAPE的新手。不知道注释。我查看了文档，但是，我仍然难以编写规则，例如输入内容：什么是rule（）xyz - ＆gt;使用规则名称，宏等。如何从初学者开始？

LIKE：

Phase:firstpass       //1 what is this phase 
Input:  Lookup        //2 when to use lookup or other other things, how to know
Options: control = brill  //3 Got it
Rule: SportsCategory      //4 Got it
Priority: 20              //5 Got it
(                              //6 
{Lookup.majorType == "Sports"} //7 wht is majorType, from where it comes 
): label                        //8 what we writeafter : 
-->                             //9 
:label.Sport = {rule= "SportsCategory" }
