No autocompletion in string interpolation

[dkirchhof]

Unfortunatelly i don't get autocompletion in string interpolations. It worked in v 1.2.x but since 1.3.x it doesn't work anymore.

Now i have installed the version from this action: https://github.com/rescript-lang/rescript-vscode/actions/runs/2628522856

While typing, no autocompletion:

While hovering, there is a type hint:

Thank you.
Could you cut it down to the shortest possible self-contained example? That will speed up fixing it.

[dkirchhof]

Sure :)
Following code breaks:

module hello = {
  world = "hello world"
}

let foo = "foo bar"

let message = `hello ${foo}`

While writing this code, I realized, that it works, if i remove the module:

let foo = "foo bar"

let message = `hello ${foo}`

[cristianoc]

module hello = {
  world = "hello world"
}

let foo = "foo bar"

let message = `hello ${foo}`

Would you give an example in correct syntax and explain what it is that does not work?

Btw have you tried asking for completion explicitly? For me it's ctrl+space.

After fixing, the example does complete for me with ctrl+space.

Just in case, autocomplete is not going to work for code with syntax errors. It can sometimes, but not always.

[dkirchhof]

Sorry, was to quick. There are several errors 🤦

With correct code, the autocompletion works.

module Hello = {
    let world = "hello world"
}

let foo = "foo bar"

let message = `hello ${foo}`

I will try to find an example where it breaks (with correct syntax :D).

Well another try:

no autocompletion for red in the interpolated string:

let red = "#ff0000"

let header = `
    color: ${red};
    background-color: ${red};
`

without the second line (background-color...), which also includes a variable, the autocompletion for red works:

let red = "#ff0000"

let header = `
    color: ${red};
`

Thanks I can see it too.

For now: tests with a repro: #483
