[Feature] Each formatter should generate separate output.

[quisido]

🚀 Feature request

Description

I want to use multiple formatters for my report, e.g.

• html formatter to generate hint-report/mysite.html
• json formatter to generate hint-report/output.json
• codeframe formatter for logs during execution
• summary formatter for logs during execution

Details

Today, if I specify a --output parameter, then this will throw errors, because json codeframe and summary all try to write to the same file.

html correctly generates a dynamic file name, allowing me to use it + another one.

I need to be able to tell each formatter whether to output to file: html yes, json yes (preferably with a different path than html), codeframe no, and summary no; because I want the latter two to output to console.

As a workaround, I've had to replace formatters: ["html"] with formatters: ["./path/to/custom-html.js"] and this implementation:

import HTMLFormatter from '@hint/formatter-html';
import type { Problem } from '@hint/utils-types';
import type { FormatterOptions } from 'hint';

export default class PatchedHTMLFormatter extends HTMLFormatter.default {
  override format(
    problems: Problem[],
    options: FormatterOptions = {},
  ): ReturnType<HTMLFormatter.default['format']> {
    return super.format(problems, {
      ...options,
      output: options.output ?? 'MY/CUSTOM/PATH/HERE', // <-- ⚠️
    });
  }
}

This isn't ideal, but hopefully it unblocks anyone else experiencing this error.

The optimal solution is likely to pass { "name": "html", "options": { "output": "..." } } the same way connectors supports options.
