Live preview for simple editors like helix #722

Open knuesel opened 3 weeks ago

knuesel commented 3 weeks ago

Motivation

Having instant preview work in Helix.

Description

The live preview would be configured from the Helix side using the initialize request. I guess this could work similarly to how it works in this fork of typst-lsp: https://github.com/tmistele/typst-lsp

(This feature is a follow-up of https://github.com/Myriad-Dreamin/tinymist/issues/357 to discuss specifically the support for editors like Helix that have limited LSP support.)

I came up with a hack to get this feature working before helix supports custom lsp commands:

We can have a small proxy between helix and tinymist which inserts the preview commands into the LSP. For now I made a proof of concept that can start and view the preview, but forward/backward sync is not available. I'll probably look at that tomorrow.

Got sync from the document to the editor working by translating the scroll events into window/showDocument requests.

I also tried adding an additional request on hover to sync from editor to document, but that seems to silently fail and I can't find exactly what I need to send

From reading the source code, it seems like something along the lines of

{"jsonrpc":"2.0","method":"workspace/executeCommand","params":{"command":"tinymist.scrollPreview","arguments":["primary",{"character":0,"event":"panelScrollTo","filepath":""/home/frans/Documents/rust/tinymist-preview-proxy/test.typp","line":10}]},"id":"1_scroll"}

But it fails silently. @Myriad-Dreamin is there something I'm missing with that command?
