readline: promote _getCursorPos to public api #30687

Js-Brecht · 2019-11-27T20:12:03Z

Aliases Interface._getCursorPos to Interface.getCursorPos, for consumption as a public API.

If so desired, I can replace _getCursorPos method calls with getCursorPos, and create an alias the other way around. Doing it like this was just the simplest way to accomplish exposing _getCursorPos.

Needs docs and a regression test and I think I have a preference for simply renaming instead of aliasing it but perhaps other maintainers feel differently.

Making this public sounds good to me, but like Ben said having a test + docs is necessary here.

jasnell · 2019-12-01T19:46:34Z

+1 to making this public as an alias with docs and tests added.

targos · 2019-12-01T20:06:55Z

can we invert the definitions so the name of the function doesn't have an underscore?

Js-Brecht · 2019-12-01T20:17:24Z

I should have some time tomorrow to get the docs & tests done. Had already planned on writing docs for it, but as a separate PR; it does make sense to just include it in this one, though.

I can also strip the underscore (and invert the alias, for backwards compatibility) since that seems to be the most desired? I see two votes for that, so far. Or maybe wait a couple more days and let more people weigh in 🤷‍♂️

Js-Brecht · 2019-12-02T19:43:35Z

I am looking into getting these tests done, but I need a bit of guidance.

_getCursorPos() is pretty well covered by the unit tests, and regression tests were what was requested. That tells me that you want to ensure that the new alias is covered by tests to ensure it incurs no breaking changes, but since the alias is running all of the same code, I'm a little bit at a loss.

Are you expecting a coverage test report of some kind for readline, or a unit test using the alias, or both?

Unit testing
1. I could write a simple unit test using the alias; that's easy enough
2. How much coverage is expected with alias unit test(s)?
  - Would successful function execution be enough for an alias?
  - If all of the existing functionality surrounding _getCursorPos() should be covered, then is there a recommended method for reusing the existing tests, but with the alias swapped in?
Coverage
1. I'm not sure what the recommended method would be for including any kind of coverage (attach to this PR, etc... ?)

Please advise.

bnoordhuis · 2019-12-03T15:26:02Z

You're right, test/parallel/test-readline-interface.js exercises _getCursorPos(). It's enough to update that to use the non-underscored name.

Js-Brecht · 2019-12-03T17:21:56Z

So basically use the alias in the tests? I had considered that, but then disregarded.

I will go ahead and strip the underscore in readline.js as requested (and invert the alias) today. Shouldn't even need to touch the tests in that case, yeah? They will all be using the alias to access the primary function.

Just committed the doc. Please let me know if it is not clear enough.

Can you update test/parallel/test-readline-interface.js to use the public API? Thanks.

Js-Brecht · 2019-12-09T00:44:20Z

@bnoordhuis done. Sorry about that

bnoordhuis

No problem. LGTM, thanks. There's a small conflict in readline.md but it should be trivial to resolve when rebasing.

Js-Brecht · 2019-12-09T18:47:22Z

One question: since this is going public now, should the YAML doc be "added: REPLACEME", or should I make it the version where the internal function was created? Looks like v0.7.6

@Js-Brecht please keep the REPLACEME as it is. It will be replaced with the Node.js version where this is first released in.

Considering versions < v13 are still widely used, is it possible to merge this into v12 & v10 as well? If so, would that mean that I should submit a PR against the v10.x and v12.x branches?

MylesBorins · 2020-01-03T18:19:27Z

@Js-Brecht I've added an lts-watch label to this PR and we'll discuss in an upcoming LTS meeting when planning the next Semver-Minor for 12.x and 10.x

It appears like this lands cleanly on 12.x with minor conflicts in the docs. As for 10.x there are more conflicts... so we may have to wait a little bit to see how feasible this change is on that release line.

Js-Brecht · 2020-01-03T19:01:58Z

@MylesBorins Okay, sounds good. Please let me know if you'd like me to submit a new PR for 10.x. I haven't reviewed the 10.x code yet, but I imagine that these changes would be simple to implement there, too. All they really required was find/replace, and the addition of one line. Implementing it directly in the 10.x branch should resolve any conflicts, I would think.
