Type inference for options and arguments works in rc.5 but fails in rc.7

[lionel-rowe]

// import { Command } from 'jsr:@cliffy/command@1.0.0-rc.7'
import { Command } from 'jsr:@cliffy/command@1.0.0-rc.5'

export const cli = new Command()
    .option('-v, --verbose', 'Enable verbose output.')
    .arguments('[...keywords:string]')
    .action((options, ...args) => {})

In rc.5, options is correctly inferred as { verbose?: true | undefined } and args as string[]; however, in rc.7, both options and args implicitly have any type unless manually annotated.

works fine for me with both versions. do you still have the issue?

[lionel-rowe]

Weird, seems the problem is very flaky. Adding console.log(options, args) seemed to fix the issue for me, and commenting out the console log didn't cause it to recur. Even weirder, clearing the Deno cache had no effect either way.

Maybe an issue with JSR/VS Code/TS/Deno/Deno lint/something else?

Still not working for me.

@lionel-rowe adding the console.log makes no difference for me.

Using:

jsr:@cliffy/command@^1.0.0-rc.7

deno 2.1.2 (stable, release, x86_64-pc-windows-msvc)
v8 13.0.245.12-rusty
typescript 5.6.2

Works fine using rc.5:

FWIW I just ran into this. Not sure what's unique about my system, apart from running WSL & VsCode.

deno 2.1.3 (stable, release, x86_64-unknown-linux-gnu)
v8 13.0.245.12-rusty
typescript 5.6.2

Interestingly when I tried the same directly on Windows, no issues.

deno 2.1.3 (stable, release, x86_64-pc-windows-msvc)
v8 13.0.245.12-rusty
typescript 5.6.2

Left is Windows, right is WSL.

And similarly now it's come good in WSL & all I did was:

• Close vscode
• Create a new folder complete seperate from the last project I was working on
• Opened vscode in this new folder
• Enabled Deno for the workspace
• Added the same test typescript to a new file
• Restored dependencies

ie: nothing too special.

I can only assume it's somehow related to deno's cache.

I have the same error, it works with rc 4 and stops with rc 5 (fedora 41 )

Cannot get it to work in rc.7 whatsoever, rc.5 works out-of-the-box.

I remember having this problem from time to time in the past. But currently I can't reproduce it. I tested it again with all rc versions, on two different laptops, with deno and node+typescript.

I also think it's either an lsp or a caching issue.

Does anyone have this issue with node as well?

[sigmaSd]

It fixed itself when I explicitly run deno check fileInQuestion.ts (it seem to have downloaded some missing files that the lsp maybe didn't download automatically)
