Execute custom function in picker keymap

[Silzinc]

Hello! I am trying to make a custom source using the "select" layout preset. Specifically, I want to add rebind a keymap to a custom function while in the input field. I tried the following, but hitting ctrl+r while in the input activates the regular binding (showing registers).

Snacks.picker.pick({
    source = "mysource",
    items = { { text = "test1" }, { text = "test2" } },
    format = "text",
    layout = {
        preset = "select",
        layout = { title = " My picker " },
    },
    win = {
        input = {
            keys = {
                ["<c-r>"] = {
                    "refresh",
                    function()
                        print("Refreshing")
                    end,
                    mode = "i",
                },
            },
        },
    },
    confirm = function(picker, item)
        picker:close()
        if item then
            print("Selected: " .. item.text)
        end
    end,
})

What do I lack for it to work? Thanks in advance!

Try this version instead. Your keymap needs to point to an action:

Snacks.picker.pick({
  source = "mysource",
  items = { { text = "test1" }, { text = "test2" } },
  format = "text",
  layout = {
    preset = "select",
    layout = { title = " My picker " },
  },
  win = {
    input = {
      keys = {
        ["<c-r>"] = { "refresh", mode = "i" },
      },
    },
  },
  actions = {
    refresh = function(picker, item)
      vim.notify("Hello, world")
    end,
  },
  confirm = function(picker, item)
    picker:close()
    if item then
      vim.notify("Selected: " .. item.text)
    end
  end,
})

I feel stupid, but I've tried that and cannot get it working. I gave up the other day as lua ls complains, so I just assumed it was not supported:

It works in my case (although the type checker complains).

Yeah, well, this is embarrassing, it's working for me too now. I have no idea what I was doing before. Sorry for the noise.

@folke I tried the following. But it looks like the parameters are different if directly passing a function to keys.
Am I doing anything wrong?

 keys = {
    ["<c-r>"] = {
        function(picker)
            -- the first arg is not a picker 
            picker:find()
        end,
        mode = "I",
    },
},

the picker uses the snacks windows module. Those have win as their param.
If you put it in an action, and then refer to the action from the key it will work.
