Pause/disable user input when displaying stats for countdown game

[gerazov]

It would be nice if the user input is paused for a bit, or even better completely disabled, after the game finishes and the stats are displayed.

Otherwise depending on what word your typing you can edit over the displayed text.

I tried the following:

1. Pause Neovim using vim.wait(500). This doesn't really work, if it does pause Vim the keypresses are still accumulated sent after the wait.

2. Turn off modifiable via api.nvim_buf_set_option(0, "modifiable", false), this I think is a good choice but can lead to a bunch of E21: Cannot make changes, 'modifiable' is off. I couldn't find if this can be suppressed at a buffer level..

3. Prompt user for input, e.g. "Press Enter to continue ..." but vim.fn.input() would open a new prompt. Maybe a custom function could be implemented 🤔

I'm pushing the 2. PR - seems the cleanest.

Ignore if it doesn't make sense 😅 :

Thanks again for the help 😁. The solution you proposed in PR makes sense, but I would like to suppress the error, I'll look into it and try to come up with a different solution. If I don't make any progress, I will merge the PR (it's much better than the current state 😀).

[gerazov]

Yeah - it would be better for sure 👍

I did go over the API, forums, LLMs, for all 3 of these, and couldn't find an elegant way to resolve this 😅

Maybe you have better luck 😉

I was just about to type this.

The only other way I thought of was to do something like this:

local keys_to_disable =
    { "a", "A", "i", "I", "o", "O", "s", "S", "x", "d", "D", "c", "C", "p", "P", "u", "U", "J", "r", "R", ".", }
for _, key in pairs(keys_to_disable) do
    vim.keymap.set("n", key, "<nop>", { buffer = 0 })
end

But it's very hacky, there are a lot of edge cases that aren't covered.

Also, when I tried using the solution you proposed in PR, I noticed that the error it was throwing was not the same as the ones that block your Neovim instance (I don't know what are they called), as I thought at first. So I think this solution is good enough until the better one emerges.

PS: I will not merge your PR, because it uses the API function that is deprecated in nightly versions, and the "use instead" function already exists in versions 0.9.x

[gerazov]

Yeah that is a hell of a hack but it could do the trick - as long as the user can't enter insert mode 👍

Great that it got solved - thanks 🙏

[gerazov]

I keep getting the E21 errors all the time 😅

Can you still merge the hack that disables all inserting commands? 🙏

[NStefan002]

Do you mind testing it now, @gerazov? I will leave this issue open for now.

Works great - thanks 🤟
