Question: how should I use timer:close?

[fvictorio]

Hi, thanks a lot for writing and sharing this.

I'm trying to show LSP diagnostics on cursor hold, but I also want to (trail) throttle it. This is what I'm doing:

function ThrottledOpenDiagnostic()
  local fn, timer = require("throttle-debounce").throttle_trailing(OpenDiagnostic, 1000)
  fn()
end

-- Show diagnostics under the cursor when holding position
vim.api.nvim_create_augroup("lsp_diagnostics_hold", { clear = true })
vim.api.nvim_create_autocmd({ "CursorHold" }, {
  pattern = "*",
  command = "lua ThrottledOpenDiagnostic()",
  group = "lsp_diagnostics_hold",
})

This works, but I'm not calling timer:close anywhere. If I call it immediately after fn(), this will obviously won't work. Could you help me understand what's the right way to use it? Thanks!

Honestly, I'd do it the same way, i.e. just call it right after the call to fn(). Your ticket made me think, however, that maybe I ought to close the timer right there in the throttle_trailing() function instead of exposing it to the user. Unfortunately it's been a while since I touched this code, so I won't be able to fix this right away I'm afraid.

Haha, understandable, thanks for responding!
