Create an LSP to supports both Monaco and CodeMirror

[wherewhere]

I see CodeMirror has a @codemirror/lsp-client plugin, and it only need a Transport to work as an LSP. Maybe Monaco also has such thing. We can create an LSP to supports both Monaco and CodeMirror easily. And if it can work with LSP, it can easily support local or online server LSP so that we don't need to wait a long time to wait it start up. This playground is loading too slowly...

Maybe Monaco also has such thing.

Yes, recently that was added officially: microsoft/vscode#262872

online server LSP

I'm not sure an LSP would help with that. .NET Lab can do more things than the LSP spec provides (like giving back compiler outputs) and we would need to have those on the server too. So, yes, a server component is under consideration, but I think it wouldn't be based on LSP.

This playground is loading too slowly...

Consider using the desktop app (currently only available for Windows), that one loads almost instantly.

SharpLab is do everything on server, so that it can load faster and have full Roslyn experience. I want a fast online playground so that I can write code when I discussing with other and they can experience the code I shared comfortably...
My playground is based on Vue so that it won't need to load .NET before starting compilation, but it still very slow when compile. It will be better to create a playground full based on HTML/JS and run compiler on server just like SharpLab...

Just want LSP can both supports Monaco and CodeMirror easily. Monaco is almost unworkable on touch devices...

Sure, but there are tradeoffs - maintaining active servers is difficult (that's likely why SharpLab became unmaintained) and expensive, especially playgrounds like this which need to be sandboxed since they can run arbitrary code. Because .NET Lab is local-only, it is very simple, hence

• it can use static hosting which is free,
• anyone can run it locally easily (and contribute to it or just use it offline) unlike SharpLab which is a distributed complexity I wasn't able to run locally when I tried,
• it will likely work even if I stop maintaining it (since it allows you to load any compiler version).

Yes, I understand and I think that's a good idea. My "not sure an LSP would help with that" was referring to the server part, but that's unrelated to your original request.

Maybe can create a bowser extension, we can create local server instead of online one.

It can compile on server and running on wasm. SharpLab even not allow to have many [...

Not sure if that would be substantially better than the desktop app that we already have, since you need to install something in either case. The desktop app supports opening/copying the shareable links too (currently there are buttons for that but could be made more automatic too). And there is result caching so people you send the link see the results fast too (that's not even limited to the desktop app).

It can compile on server and running on wasm.

The slow thing is the initialization. You can see that subsequent compilations after the first one are fast. So running the app locally would also require the slow initialization (e.g., downloading all the runtime DLLs), I'm afraid.

I see the desktop version is not free :(
(Is that server version will also not free? Maybe we can have an option to set custom server so that we can host our own servers, such as using vercel.app

The slow thing is the initialization.

Decompilation and other not running tasks can still working on server, just slow on first run. So the really slow is the website is build on .NET so that it should download all the .NET at beginning...

Hi, I reviewed 'Create an LSP to supports both Monaco and CodeMirror' and can start immediately. I can deliver a first usable version quickly and iterate based on your feedback. If this scope still matches your priority, I can proceed right away.
