Ruby LSP

No documentation on hover in nvim

Using Shopify ruby-lsp.

~/dotfiles/.config/nvim/lsp/ruby-lsp.lua

return {
  cmd = {
    "ruby-lsp",
  },
  filetypes = {
    "ruby",
  },
  root_markers = {
    "Gemfile",
    ".git",
  },
  init_options = {
    formatter = "standard",
    linters = { "standard" },
    hover = true,
    documentHighlight = true,
    addonSettings = {
      ["Ruby LSP Rails"] = {
        enablePendingMigrationsPrompt = false,
      },
    },
  },
}

Note that even with hover = true, kbd:[C-k] would say “No information available.”

Try removing the cache and restarting LSP or the whole nvim:

$ rm -rv ~/.cache/nvim

Then, kbd:[C-k] works for the first time, but not a second or subsequent times. Same problem calling :lua vim.lsp.buf.hover() directly.
