Code suggestions in interpolations in a quoted string don't come automatically

• Extension version: 3.1.11
• Operating system: macOS

Reproducible Case: https://github.com/MenSeb/some-sass-bug/commit/48d7175c264b08107e7be8a9ed2566a5bc0af691

Steps to Reproduce:

1. Open index.scss
2. On line 6 ($test: "#{test.hello()}") the interpolation should show code completions once you finish typing "#{.

Investigating in #186, it seems like VS Code does not send onCompletion requests even if we last responded with isIncomplete = true set on the result.

As mentioned in https://github.com/wkillerud/some-sass/issues/186#issuecomment-2256681536, there are workarounds:

• Trigger code suggestions manually with Ctrl + Space
• Skip the quotes

[MenSeb]

Ok, I can confirm that without the quotes it shows suggestions and with quotes using crtl + space works.

I may have found something else related to this issue/bug.

If I want to include a mixin from another file with the @include rule it works, for example:

@use './test' as test;

@include test. // shows the existing mixins

But if I want to use a function or variable in a mixin from an @include rule, it won't work, for example:

// _test.scss
@function name() {
    @return 'Some Sass';
}

// _index.scss
@use './test' as test;

// works correctly here, but it only shows existing mixins
// it should show the variable $name and the function name()
@include test.hello(test.name());

This conflict seems to be related to the fact that it only expects mixin since the line includes a @include rule. This raises another issue related to what it shoud display depending on the context in which it is used. For example:

// _index.scss

// work with the ctrl + space, but it shows everything, even mixins?
$test: "#{test.hello()}"; 

// works correctly here, but it shows everything, even mixins?
#{test.selector()} { 
    width: 100%;
}

The repository is up to date with all of this.

Thanks @MenSeb, the bug of variables and functions not being suggested as mixin parameters is fixed in 3.3.0.

works correctly here, but it shows everything, even mixins?

I don't see mixins in my code suggestions there. There are two suggestions for hello, but both of them are for the function (one with, and one without parameters).

[MenSeb]

Thanks @wkillerud it works perfectly!

I don't see mixins in my code suggestions there. There are two suggestions for hello, but both of them are for the function (one with, and one without parameters).

My apologies, I may have confused functions with mixins at that moment, I can't reproduce what I pointed out.

I may have something else to add, I don't think it as a bug, but rather a feature that could be implemented. It is related to code suggestion, would you rather have a new issue for that or should I continue here? (I am updating the repo right now)

It does behave differently in some situation, I don't know if it is related to the extension tho.

The suggestions won't show what was forwarded from a sass package.

// _sass.scss

@use 'sass:meta';

@function is-number($value) {
    @return meta.type-of($value) == number;
}

// _test.scss

@forward 'pkg:sass-true';
@forward 'sass:meta';
@forward './sass';

// index.scss

@use './test' as test;

// The custom logic is forwarded and shows suggestions
@debug test.is-number(10);

// The package pkg:sass-true is forwarded and shows suggestions
@debug test.$catch-errors;

// The package sass:meta is forwarded but it won't shows suggestions
@debug test.type-of('string'); 

The repo is up to date, please let me know if you wish to open a new issue for that.

Interesting, I hadn't considered that case 😄 The completions for sass built-ins get added here, but only if they are @used in the current document.

https://github.com/wkillerud/some-sass/blob/5f29b4e208b2c93850b01f7fac71f4ad73107a57/packages/language-services/src/features/do-complete.ts#L608-L624

I'll take a look at adding support for @forward in this case.

No need for a new issue this time, but if you find something else it would be great if you opened a new issue – easier for me to keep track that way 👍

Edit: fixed in 3.4.0

[MenSeb]

I came up with this case while trying to forward "enhanced" sass modules with more utilities added to them haha

It works like a charm, thank you so much for your time and development :)
