read settings config for rules like remark-lint-strong-marker

As title

Problem

var report = require('vfile-reporter')
var remark = require('remark')
var emphasisMarker = require('remark-lint-emphasis-marker')
var strongMarker = require('remark-lint-strong-marker')

remark()
  .use({
    settings: { emphasis: '*', strong: '*' },
    // ^ `remark-stringify` settings.
  })
  .use(emphasisMarker)
  .use(strongMarker)
  // ^ two `remark-lint` rules.
  .process('_Hello_, __world__!', function(err, file) {
    console.error(report(err || file))
    console.log(String(file))
  })

There is no warning at all.

Expected behavior

emphasisMarker and strongMarker can read remark-stringify settings automatically to set the default style, so that the user don't have to config same thing twice.

That might work 🤔

Rules don’t have access to settings though. So that would mean some changes have to land in unified-lint-rule first.

I think it’s fine to do this. One part is:

remark-lint/packages/unified-lint-rule/lib/index.js

Line 64 in 909d9cc

})(tree, file, options)

which should probably be:

}).call(this, tree, file, options)

then, this.data('settings') could be uses in the rules, based on https://github.com/syntax-tree/mdast-util-to-markdown#tomarkdowntree-options, to replace the default where needed.

@JounQin Is this something you could help with?

[JounQin]

@wooorm What kind help do you mean? Raising a PR as you suggested or something else?

[wooorm]

Yeah, if this is something you could and would want to work on?
I could perhaps also work on it?

[JounQin]

I'd like to help, but I'm a bit busy these days, and I'm not so familiar with the code base.

I'll let you know whether I have time to work on before tomorrow, is this OK?

[wooorm]

Of course, no rush!
Can also be in a week or so.
Or if you’re not interested, that’s also okay!
