非 JS 文件中更漂亮的 Pragma 支持

Question

Adding "requirePragma": true , to the prettier config makes it format a files that contain a special comment only.

Here is a special comment for .js and similar files, according to the docs :

/**
 * @prettier
 */

or

/**
 * @format
 */

How to make such a comment in files, such as .html or .json , where comments of this kind are not allowed?

For example <!-- @prettier --> is not recognised as a special comment in .html files

Answer 1

For anyone ending up here in the future:

This appears to be partially solved today, but not for all formats.

• .md gets <!-- @format -->
• .html gets <!-- @format -->
• .yml gets # @format

JSON still doesn't get anything, which makes sense.

The documentation doesn't mention this explicitly: https://prettier.io/docs/en/options.html#require-pragma
