textlint: support --rule ./path/to/rule.js

[azu]

We want to support file path to rule file for command line flag and textlinrc.

Actual(Current)

--rule support only rule module name.

textlint --rule <rulename>

Expected

textlint --rule <rulename>
textlint --rule ./path/to/rule.js

Purpose

It help to debug developing rule.

UseCase: check the developing rule with actual texts.

cat example.md | xargs ./node_modules/textlint/bin/textlint.js --rule lib/my-rule.js -f pretty-error

In my real usecase: test my rule with some corpus.

technological-book-corpus-ja | xargs ./node_modules/textlint/bin/textlint.js --rule lib/my-rule.js -f pretty-error

Workaround

Install the rule and textlint to global

# install the rule to global
$ npm i -g . textlint technological-book-corpus-ja
$ technological-book-corpus-ja | xargs textlint --rule textlint-rule-ja-no-redundant-expression -f pretty-error

Task

• support file path in .textlinrc
• support file path in --rule flag

{
   "rules": {
     "./path/to/rule.js": true
   }
}

I don't know that the above case is safe?

Maybe, Other implementation is suitable for this purpose.

Sob! I came here, wanting a solution to the statement in https://github.com/textlint/textlint/blob/master/docs/faq/failed-to-load-textlints-module.md :

• If you have installed textlint as --global(-g), must install each rule as --global.
• If you have installed textlint as --save-dev(-D), must install each rule as --save-dev.

It sounds like this would be that solution - but it's not nearly implemented.
