New Rule: indent

[LJNeon]

Rule details

Should function similarly to the indent rule for JavaScript.

What type of rule is this?

Suggests an alternate way of doing something

Example code

There are many different standard indentations:

1. No whitespace

   {"a":5,"b":true}

2. Tabs

   {
   "a": 5,
   "b": true
   }

3. Two-space

   {
   "a": 5,
   "b": true
   }

4. Four-space

   {
   "a": 5,
   "b": true
   }

   and so on.

Participation

• [ ] I am willing to submit a pull request to implement this rule.

Additional comments

Could easily follow the standard set by JSON.stringify()s space option. If that doesn't seem like a good idea, then could follow the standard set by eslint's indent rule.

hi, thanks for the issue! however, formatting-rules have been deprecated in eslint (https://eslint.org/blog/2023/10/deprecating-formatting-rules/). We might want to follow the same strategy here.

[LJNeon]

In the case of eslint they were deprecated and moved to their own package. But there's no @stylistic/json package for the same to happen here.

We're not going to be adding formatting rules to this package. Please use a formatter like Prettier for this purpose.
