feature(input): keep history of inputs for named prompts

[jdrouhard]

Did you check the docs?

• I have read all the snacks.nvim docs

Is your feature request related to a problem? Please describe.

vim.fn.input() and vim.ui.input() both keep a separate history for inputs with the same prompt. That is, when typing input for a particular prompt, you can press the up arrow and get previous inputs you've used for it.

I use this for repeating searches I've typed before, using something like:

local function search()
  vim.ui.input({ prompt = "Grep For" }, function(input)
    Snacks.picker.grep({ live = false, search = input })
  end)
end

M.keys = {
  { '<leader>s',   search, { desc = 'grep' } },
  { '<leader>rg',  function() Snacks.picker.grep() end },
}

Describe the solution you'd like

I can type <leader>s followed by up and scroll through my history of typed greps. Snacks.input doesn't seem to support this, but would be amazing if it did.

Describe alternatives you've considered

For now, I'm using vim.fn.input to type my search queries instead of vim.ui.input, but would love to switch.

Pickers already support history with <c-Up> and <c-Down>

[jdrouhard]

@folke - For sure, pickers definitely support it, but this was specifically a feature request for Snacks.input (which is supposed to be a drop in replacement for vim.ui.input). The latter does support a history, but the former doesn't yet.

I guess my usage of picker in my example was confusing but in fact it was irrelevant since you could use the input for anything. Is it possible to reconsider opening this request?

Thanks for making such fantastic quality plugins.

Just added this. Default keymaps are <Up> and <Down>

[jdrouhard]

Thank you! Does it save the history to shada so it is persistent between neovim sessions?

Edit: #528

[folke]

Added persistent history as well

Incredible. Thank you @folke!
