Custom language support

[jakoss]

Hello,
I'm trying to add support for C# language using this configuration:

{
  "languages": {
    "c_sharp": {
      "extensions": ["cs", "csx"],
      "grammar": "c_sharp",
      "comment_prefix": "//"
    }
  },
  "lsp": {
    "c_sharp": {
      "command": "csharp-ls",
      "enabled": true,
      "args": []
    }
  }
}

When i load fresh with this configuration i have no errors, but i still don't have any syntax highlighting and the lsp is not detected ("No LSP server configured for this file type"). Am i doing something wrong here? I see that you have dependency on the c_sharp treesitter grammar in your crate file

I also tried this with no luck, hard coded the paths to the lsp:

"c_sharp": {
      "command": "/home/csharp/csharp-language-server",
      "args": [
        "--solution-path",
        "/home/FreshTest/FreshTest.sln"
      ],
      "enabled": true,
      "auto_start": true,
      "process_limits": {
        "max_memory_mb": 31698,
        "max_cpu_percent": 90,
        "enabled": true
      }
    }

The language servier I have downloaded is this one:

@jakoss try with latest master (or version >= 0.1.22)

should be fixed by commit aa59fda

Work great now, thanks

The syntax highlighting is working but I do get an error that looks like the args are not being forwarded, although I'm not sure...it could also be the language server I'm trying to use:

thread 'main' (249009) panicked at src/path.rs:15:39:
Root path not part of initialize notification: Root URI/path was not given by the client
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

using the same arguments on the command line gives me this, which looks more positive:

{"jsonrpc":"2.0","method":"window/logMessage","params":{"type":3,"message":"[Program] Language server initialized"}}^C

@sfjohansson This error is from the language server or is Fresh itself crashing?

[sfjohansson]

Fresh itself is not crashing, displayed in tab:

ok that's from the lsp server. reproduced here - taking a look
