easy-dotnet.nvim LSP integration

[GustavEikaas]

Hello,

I am the author of easy-dotnet.nvim. I recently added a Roslyn integration, the plugin now ships the Roslyn language server and configures it automatically. I see that you have roslyn.nvim integration in you readme, would it be possible to achieve the same for easy-dotnet?

Thanks for your time, and for your work on your plugin!

Essentially, you need to just add some dll's to the runtime command for the roslyn lsp
and then there are some autocommands to make the LSPs communicate to each other through the editor

You should be able to work out what you need to add to your plugin by reading the source of rzls.nvim and roslyn.nvim

I'd be more than happy to review a PR for docs changes as appropriate

Awesome, I think I remember there were some event emitter thing in roslyn.nvim used by rzls.nvim but I might be misremembering. Ill give it a go and report back. Thank you for the quick reply!

Oh there are some handler's that we provide too. So you'll need a way to invest those into the lsp config you provide

I'm close I think but I keep getting this error, any ideas?
easy_dotnet: -32000: Attempted to retrieve a Document but a TextDocument was found instead.

I'm adding all the handlers in my lsp config

          local ok, razor_handlers = pcall(require, "rzls.roslyn_handlers")

          local razor = ok and { handlers = razor_handlers } or {}

          local lsp_opts = vim.tbl_deep_extend("force", M.lsp_config, razor, user_lsp_config, {
            cmd = function(dispatchers) return vim.lsp.rpc.connect(pipe_path)(dispatchers) end,
            root_dir = root,
          })

I'm also sourcing the source generator, targets file and vscode razor extension

    psi.ArgumentList.Add($"--razorSourceGenerator={razorDllPath}");
    psi.ArgumentList.Add($"--razorDesignTimePath={razorTargetsPath}");
    foreach (var dll in GetAnalyzers(options))
    {
        psi.ArgumentList.Add("--extension");
        psi.ArgumentList.Add(dll);
    }

lsp.log

From memory I think that means that the extension is being added properly

The extension is shipped with the rzls language server from mason

Ah okay I didnt read the fine-print as I was testing on windows, which apparantly doesnt work. Am I understanding it correctly that running rzls.nvim on windows does not work at all without wsl? Is this a rzls.nvim issue or roslyn issue?

Native Windows support doesn't work at this time, due to path normalization.

[tris203]

I think windows support works now after we did some changes on the path stuff

But I don't have a window machine to test on

Okay I configured my server to use the mason version but everytime I load a .razor file my log is spammed with this
easy_dotnet: -32000: Razor source generator did not produce a host output for project 'aspire.Web (net9.0)': any idea what might be wrong here? Using roslyn.nvim + rzls.nvim it works but not when using the LSP through my server
