Workspace diagnostics for Roslyn language server

On demand generation of workspace diagnostics for your .NET project.

📦 Installation

-- lazy.nvim
{
  "bosvik/roslyn-diagnostics.nvim",
  -- lazy load on filetype
  ft = { "cs", "fs" },
  opts = { },
}

Important

For large solutions roslyn.nvim needs to be setup with dotnet_analyzer_diagnostics_scope = "openFiles" to avoid roslyn crashing.

 {
   "seblj/roslyn.nvim",
   ft = { "cs", "csproj" },
   opts = {
     config = {
       settings = {
         -- ...
         ["csharp|background_analysis"] = {
           dotnet_analyzer_diagnostics_scope = "openFiles",
           dotnet_compiler_diagnostics_scope = "fullSolution",
         },
         -- ...
       },
     },
     -- ...
   }
 }

⚙ Configuration

You can configure a different function to filter which files should be processed.

-- lazy.nvim
{
  "bosvik/roslyn-diagnostics.nvim",
  ft = { "cs", "fs" },
  opts = {,
    -- Optional filter function to filter out files that should not be processed
    -- This is equivalent to the default filter.
    filter = function(filename) 
      return (filename:match("%.cs$") or filename:match("%.fs$")) and not filename:match("/[ob][ij][bn]/")
    end,
    -- set custom diagnostic opts
    -- refer :h vim.diagnostic.Opts
    diagnostic_opts = {
      virtual_text = {
        prefix = "●",
      },
      severity_sort = true,
      signs = {
        text = {
          [vim.diagnostic.severity.ERROR] = "",
          [vim.diagnostic.severity.WARN] = "",
          [vim.diagnostic.severity.INFO] = "",
          [vim.diagnostic.severity.HINT] = "",
        },
      },
    },
  },
  keys = {
    { "<leader>cD", "<cmd>RequestDiagnostics<cr>", desc = "Request diagnostics", ft = { "cs", "fs" } },
  }
}
