custom keybinds for Snacks.picker.files and more

[nautilor]

I have created this custom function to use with the explorer

local function choose_picker_action(source)
	local Snacks = require("snacks")
	local explorer = Snacks.picker.get({ source = source })
	if #explorer == 0 then return end
	local node = explorer[1]
	local cursor = node.list.cursor
	local item = node.finder.items[cursor]
	if item == nil then return end
	if item.type ~= "directory" then
		local ok = node:action({ "pick_win", "jump" })
		if ok then return end
	end
	node:action({ "confirm" })
end

mapped like this

picker = {
	enabled = true,
	sources = {
		explorer = {
			auto_close = true,
			win = {
				list = {
					keys = {
						["a"] = "explorer_add",
						["d"] = "explorer_del",
						["r"] = "explorer_rename",
						["c"] = "explorer_copy",
						["p"] = "explorer_paste",
						["u"] = "explorer_update",
						["x"] = "explorer_move",
						["y"] = "explorer_yank",
						["<CR>"] = function()
							choose_picker_action("explorer")
						end
					}
				}
			}
		},
	},
}

so that when from the explorer i press <CR> it does the following

• If is a directory navigate into it normally
• If it's a file and I have no split open it
• If it's a file and I have some splits let me choose where to open it

Basically merging the and functionality in one

and I was wondering if this was possible also for Snacks.picker.files/grep/buffer and it would be really useful

I tried adding files to the sources but without any luck

1. Use <S-CR>. It's already possible without additional configuration.

snacks.nvim/docs/picker.md

Line 234 in 9912042

["<S-CR>"] = { { "pick_win", "jump" }, mode = { "n", "i" } },

2. Here is an example of the way to define an action:

---@module 'snacks'

return {
  "folke/snacks.nvim",
  lazy = false,
  ---@type snacks.Config
  opts = {
    picker = {
      actions = {
        print_item = function(picker, item)
          vim.print(item)
        end,
      },
      win = {
        input = {
          keys = {
            ["<F1>"] = { "print_item", mode = { "i", "n" } },
          },
        },
        list = {
          keys = {
            ["<F1>"] = "print_item",
          },
        },
      },
      sources = {
        explorer = {
          actions = {
            print_item = function(picker, item)
              vim.print({ cwd = picker:cwd(), item = item })
            end,
          },
          win = {
            input = {
              -- keys = { ... }
            },
            list = {
              -- keys = { ... },
            },
            preview = {
              -- keys = { ... },
            },
          },
        },
      },
    },
  },
}

Thanks for the heads up on actions, the reason I am using my implementation in the explorer is that for folders I cannot used <S-CR> cause snacks would open them in the split instead of expanding the tree so I combined them both in a single mapping <CR> and i wanted to do the same for other pickers such as files/grep/etc...

            pick_win = function(picker, item, action)
              if item.dir then
                picker:action("confirm")
                return true
              else
                return Snacks.picker.actions.pick_win(picker, item, action)
              end
            end,
          },
        },
      },
    },
  },
}

pick_win does not work if there's no splits, i manage to solve it by using

picker = {
	actions = {
		smart_open = function(picker, item)
			if not item.dir then
				local ok = picker:action({ "pick_win", "jump" })
				if ok then return end
			end
			picker:action({ "confirm" })
		end
	},
	win = {
		input = {
			keys = {
				["<CR>"] = { { "smart_open" }, mode = { "n", "i" } },
			},
		},
		list = {
			keys = {
				["<CR>"] = { "smart_open" }
			},
		},
	},
	enabled = true,
	sources = {
		explorer = {
			auto_close = true,
			win = {
				list = {
					keys = {
						["<CR>"] = "smart_open"
					}
				}
			}
		},
	},
}
