综述

VSCode可以很方便地编辑用户自定义代码段，即文件>首选项>用户代码片段或直接在命令面板搜索snippets，根据示例编写代码段即可。但是我在编写markdown代码段后出现了问题：输入prefix没有自动提示，即markdown没有intellisense功能。

解决方法

• 在文件>首选项>设置中搜索tabCompletion选择on或者onlySnippets

• 或者直接在settings.json文件中添加如下代码：

"editor.tabCompletion": "onlySnippets"

然后在编写markdown文件时输入相应的prefix按Tab键即可插入代码段。

By default, tab completion is disabled. Use the editor.tabCompletion setting to enable it. These values exist:

• off - (default) Tab completion is disabled.
• on - Tab completion is enabled for all suggestions and repeated invocations insert the next best suggestion.
• onlySnippets - Tab completion only inserts static snippets which prefix match the current line prefix.

In Visual Studio Code, snippets show in IntelliSense (Ctrl+Space) mixed with other suggestions as well as in a dedicated snippet picker (Insert Snippet in the Command Palette). There is also support for tab-completion: Enable it with “editor.tabCompletion”: “on”, type a snippet prefix, and press Tab to insert a snippet.
