This plugin provides a VERY basic automation to restart any LSP client with tracing enabled.

use({
    "neandertech/nvim-langoustine",
    requires = {
      { "nvim-telescope/telescope.nvim" }
    },
})

It is packaged as a Telescope extension, so you will need to load it as such (this goes into your init.lua):

require('telescope').load_extension 'langoustine'

You can then invoke (or bind to a hotkey) the following command:

:Telescope langoustine enable_lsp_tracer

What this plugin does is replace the original command cmd which was used to start LSP server with a modified command that prepends langoustine tracer parameters.

By default it prepends langoustine-tracer trace - assuming you have a langoustine-tracer binary set up globally.

You can modify that by configuring the extensions section when you set up telescope:

  require("telescope").setup({
    extensions = {
      langoustine = {
        command_prefix = { "langoustine-tracer-dev", "trace" }
      }
    }
  })
