🕗 Version & Regression Information

• This is the behavior in every version I tried, since the feature was introduced in 3.7

Playground link with relevant code

💻 Code

declare function assert(v: any): asserts /* | */

🙁 Actual behavior

Typing v after asserts brings up the completion list with void at the first position. I'm used to accept the first completion, so I end up with an invalid asserts predicate.

🙂 Expected behavior

List all parameter names of the function and/or this

Hi is this bug being worked on?

[Simar-B]

Hi this is my first time working with the typescript compiler I'm wondering if any of you know what files I should be looking at to fix this issue?

[ajafff]

@Simar-B the relevant code should be somewhere in this function:

TypeScript/src/services/completions.ts

Line 161 in 154f209

export function getCompletionsAtPosition(

Unfortunately I cannot give any more guidance as I don't have any experience with completions and don't know how to debug this code.

@ajafff Is your playground code a complete example? It's throwing error on asserts return type

[ajafff]

The code is intentionally incomplete to show where I expect a completion.
The code becomes valid if you replace the comment with v

Hi @Simar-B . Are you still interested on working on this?

If so, I might could give more suggestions for you (recommends).
If not, I'm also happy to working on this.

Hi @Kingwl. Sorry for not mentioning it earlier but I am not working on this.

[Kingwl]

@Simar-B Okay. Never mind.

Hi @Kingwl , are you working on this? I haven't worked on TypeScript in the past and it looks like a good first issue :)

@omril321 I don't know if he was, but I started working on it this morning, since I didn't see anyone else say they had.
