Fix `new Buffer` deprecation warning by updating dependency

[jacobq]

Right now, it seems this project uses a very old version of inquirer. What would it take to upgrade that? The main reason I care is because this seems to be blocking resolution of an annoying deprecation warning when using yarn with Node >= 10 because it uses commitizen#inquirer#external-editor#chardet (v0.4.2, which uses new Buffer(...) -- v0.7.0 updates to Buffer.alloc(...), but it's not getting used because here inquirer is pinned to 1.2.3).

It looks like these are the breaking changes between 1.x and 6.x:

• 2.x: Drop support for node 0.10 and 0.12
• 3.x: Drop support for Node < 4
• 4.x: The core codebase went through a major es5 to 6 refactor. As such, we're dropping support for Node 4. This change will likely require changes to the community Plugins as es6 classes are enforcing more restriction (like constructor can only be invoked with new)."
• 5.x: Upgrade to RxJS v5 which updates a bunch of Reactive interface method names. For people not using the Reactive interface directly, this new major release should just work out of the box.
• 6.x: Update to Rx.js v6

We could probably go to 3.x without problem, unfortunately going beyond that would be a breaking change from our side.

That being said, us passing inquirer to the adapter is deprecated, so we could probably create a breaking change that removes it 🙌

In case you want to go ahead with the upgrade after all, I recently upgraded Inquirer.js from version 3 to 6 in inquirer-autocomplete-prompt. I tried to make the commits as granular as possible.

Maybe the pull request is good reference:

mokkabonna/inquirer-autocomplete-prompt#64

Nice!

The problem we have here is that we simply pass inquirer to the adapter, and thus we cannot really migrate since that code is beyond our reach 🤔

Thanks for considering this; I've never used inquirer and am not even sure what "the adapter" is, so I don't think I should try to dive in and make a PR unless you're for sure never going to get around to this.
A quick "band-aid" may also be possible if you could upgrade transitive dependency chardet to v0.7.0 without changing anything else (e.g. https://yarnpkg.com/lang/en/docs/selective-version-resolutions/ or https://github.com/rogeriochaves/npm-force-resolutions) as I don't think its API has changed significantly between that and its current version.

I think it’s time for us to release a new 2.x version with some deprecation warnings about specific items. Then 3.x will just be a bigger breaking change release than we’d anticipated. IMO it is worth it at this point.

prompter here is an external adapter, e.g. cz-conventional-changelog

cz-cli/src/commitizen/commit.js

Line 48 in 247d2c4

prompter(inquirer, function (error, template, overrideOptions) {

I'd be happy with a PR that removes inquirer, and passes in an object that mimics the API, but throws a helpful error whenever it's being called, something like this:

const inquirer = {
  prompt () {
    throw new Error('Being passed an instance of `inquirer` from `cz-cli` is removed, please depend on `inquirer` directly')
  }

  // all other methods...
}

Sounds good
