Signature help, document hover, diagnostics don't show up

[duydang2311]

Hello, I finally get typescript-language-server to work after following the guide in Troubleshooting.
Auto-completion works as expected but not for signature help, document hover or even diagnostics.

1. Triggering signature_help does not show signature popup or any errors in the log, but hover does have an error in the log.
2. I'm assuming that diagnostics is shown in the gutter automatically? If my assumption was correct, I had a wrong syntax error in my code but the hint wasn't displayed for me.

Reproduction steps

Create a keybinding for signature_help only, hover already has space-k.

[keys.insert]
"C-k" = "signature_help"

Triggering signature_help or hover, and none of them shows anything.

chat.registerCmd('v', onV);
     ^^^^^^^^^^^
     cursor position where i trigger signature_help, hover

Only hover prints an error as in the log below.

Environment

• Platform: Windows
• Helix version: helix 0.5.0

~/.cache/helix/helix.log

2021-12-19T20:31:22.080 helix_term::commands [ERROR] hover contents [LanguageString(LanguageString { language: "typescript", value: "function registerCmd(cmd: string, callback: Callback): void" }), String("")]

Signature help is not yet fully implemented, see #1331.

Oh, I see.
Same for document hover and diagnostics, is it?

[sudormrfbin]

Hover and diagnostica should work properly though. Can you try with another typescript project ?

[archseer]

The documentation popups are fixed in master, but not in 0.5. The typescript server uses MarkedString e128a87

[archseer]

Diagnostics should work. You can see if the LSP is working by running helix with the -v flag and checking the logs for LSP traffic

[duydang2311]

This is the log when I run with -v flag, LSP seems like working but there's no diagnostics.

Hover and diagnostica should work properly though. Can you try with another typescript project ?

There's an initialization error when I try with a new typescript project.

Reproduction steps

• Create a directory for the new project.
• npm install typescript --save-dev.
• npx tsc --init.
• Create index.ts.
• Open helix with the current working directory is the project directory, then open index.ts with file picker.

Here's how the project looks:

    Directory: F:\coding\ts-project

Looks like we can't find the workspace root. It currently uses .git to find the root, and since you're not using version control it can't find it.

There's some glue code to also consider marker files (e.g. package.json) but it's not currently hooked up

[archseer]

Should be resolved by now
