Auto complete on analysis option not working correctly

[FMorschel]

Working as intented

If you have on analysis_options.yaml the following:

include: package:lints/recommended.yaml

linter:
  rules:
    - ^

analyzer:
  enable-experiment:
    - ^

On either ^ it will show you the possible rules for lints or possible experiments we have.

If you trigger auto-complete (CTRL + Space) on the left of the file, it will show you the sections; analyzer, linter, code-style, etc.

---

NOT Working as intended

If you do that with one indentation inside analyzer it still shows the same as the previous paragraph.

If you do that on ^ below:

analyzer:
  language:
    ^

Here is the output:

This is a mix of the possible entries for the analyzer section and the entire file-valid sections and (at the end because this is alphabetically sorted) the valid options for the analyzer.language section (strict-inference, strict-casts, etc).

---

Also, on another note, we can't do with the analyzer.language section what we can with the linter.rules section of posting them on a list. We need to add each one with : true (again, the auto-complete here is totally lost when it would show true/false options it shows a lot more).

Do you have a complete file sample that triggers this? When I try reproducing, I see this:

Part of the difference might be due to me having "editor.wordBasedSuggestions": "off" off. By default, VS Code will add suggestions for all the words it finds in the document (I think this is poor behaviour myself). However, even with that enabled, the case above works correctly (but all the words from the document do show up in some other places).

Not on the same OS, will test it out later today on that same project. But there is still this problem with the parts for the analyzer scope:

Also,wordBasedSuggestions is set to off on Dart -> User

But I'm unsure of what it means. Would it only be set to off on .dart files?

Correct. I have it set to off in my VS Code User Settings so it's disabled for all languages, because IMO it's never useful. I think if you turned it off globally (or for YAML), you might be seeing empty results in the places where you see those (I think it might only appear as a fallback if the server doesn't return anything?).

I can reproduce this one:

I`ve tested it again and I can confirm that was it.

I've also confirmed that the case you managed to repro above only happens if you already have one of the internal options for analyzer later.

If you trigger autocomplete after, it still thinks you're at the last spot:

See that there is no auto-complete option for true/false here and as I mentioned at the start, for some reason, this is not coherent with the linter->rules section where we can use a yaml list.
