How to Use Yasnippet?

Find Out What Templates Are Available
1: when coding HTML. YASnippet->html-mode->submenu -> 〖<body>…</body>〗 ->“body =>” it means type body -> press Tab -> it'll expand to <body> </body>.

2: folder /snippets/html-mode/-> a list of files.the first part before “.”, is the abbreviation you can use.

#name : is for a short title for the template.
# -- : Everything above that line is either comment or directive. Below the line is the actual template definition.

自定义模板

1：当在文件中，不指明key的话，文件名中不论有没有点号，都是作为一个整体作为标识。只要文件名不一样就是不同的模板，内容无视。
2：但是当你在文件中指定了key的话，只要内部name一样，它们就会互相覆盖。前提是name不一样，它才会展现出来，并且这个时候key作为标识。
