"No information available" for some LSPs

[mauriciotp]

I was editing my React project, and for no reason, after using hover provided by lsp, a message shows up saying: "No information available" for each Lsp that nvim notify can't get information. For example, i'm using tailwindcss and cssmodules servers, and after pressing shift k (keymap for 'vim.lsp.buf.hover()'), nvim notify generates two messages, one for each server (i presume). Any idea on how to solve it? I was wondering if i could manage to disable the message "No information available" for that specific case that nvim notify can't get information about it.

for that specific case that nvim notify can't get information about it.

nvim-notify is purely a messaging service, it has nothing to do with the message contents. This is the built-in lsp hover handler.

I'd suggest just writing your own handler for hover to not send these messages. Here is the default handler with the message commented out:

    vim.lsp.handlers["textDocument/hover"] = function(_, result, ctx, config)
      config = config or {}
      config.focus_id = ctx.method
      if not (result and result.contents) then
        vim.notify('No information available')
        return
      end
      local markdown_lines = vim.lsp.util.convert_input_to_markdown_lines(result.contents)
      markdown_lines = vim.lsp.util.trim_empty_lines(markdown_lines)
      if vim.tbl_isempty(markdown_lines) then
        -- vim.notify('No information available')
        return
      end
      return vim.lsp.util.open_floating_preview(markdown_lines, 'markdown', config)
    end
