How to format code

[STofone]

I want to format selected code (or auto format after save or after setValue).
The solutions i found is to use indentLine. But when i print the reference of CodeMirror Component, there's no method indentLine.

<CodeMirror
  ref="codeMirror"
  v-model="code"
  :extensions="extensions"
  :tab="true"
  placeholder="Please enter the code."
  style="height: 100%"
  @change="save"
></CodeMirror>

......
console.log(codeMirror)

It seems that this function does not exist in the CodeMirror standard, but it seems possible to do it by implementing the process described on the following site.

In this program, I think you can do this by putting this function in @update.
