Snippets是可以复用的代码片段模板,可以帮助你快速输入大量重复内容,极大提高写作效率。
在Sublime Text中新建Snippet,选择菜单:Tools->Developer->New Snippet...,Sublime Text会生成一个Snippet模板。

<snippet>
<content><![CDATA[
Hello, ${1:this} is a ${2:snippet}.
]]></content>
<!-- Optional: Set a tabTrigger to define how to trigger the snippet -->
<!-- <tabTrigger>hello</tabTrigger> -->
<!-- Optional: Set a scope to limit where the snippet will trigger -->
<!-- <scope>source.python</scope> -->
</snippet>
将模板内容修改如下:
<snippet>
<content><![CDATA[
Hello, this is a snippet.
]]></content>
<!-- Optional: Set a tabTrigger to define how to trigger the snippet -->
<tabTrigger>hello</tabTrigger>
<!-- Optional: Set a scope to limit where the snippet will trigger -->
<scope>source.python</scope>
</snippet>
简单介绍一下各节点含义(看不懂没关系,后面的实际操作会让你豁然开朗,可以回头再看^_^
):
-
content
节点内容表示实际的代码片段。 -
tabTrigger
节点内容表示用来输入代码片段的快捷字符串。 -
scope
节点内容表示代码片段会在哪种上下文环境下激活, 比如上面代码定义了source.python, 意思是这段代码片段会在python语言环境下激活。注意:Scope不是文件扩展名,可以从菜单:Tools->Developer->Show Scope Name查看当前文件扩展名对应的Scope。
把修改后的模板保存为文件hello.sublime-snippet
(保存目录保持默认打开的目录即可)。
新建文件t.py
,在文件中输入hello
,按下Tab
键,则输出如下:
好了,这就是Snippet最基本的用法,是不是很简单很强大!更多高级功能请参考官方文档http://docs.sublimetext.info/en/latest/extensibility/snippets.html
一个常见问题:针对Markdown文件的Snippet没有出现在自动补全列表中
解决办法是选择菜单Preferences->Settings,在右侧的窗口中增加如下设置:
"auto_complete_selector": "meta.tag - punctuation.definition.tag.begin, source - comment - string.quoted.double.block - string.quoted.single.block - string.unquoted.heredoc, text",
