Add harpoon2 as an option

[stuckinsnow]

Hello,

I love fzf-lua! And I wanted to contribute something. Harpoon2 is extremely popular, and I made a function to connect it to fzf-lua. In my opinion, the result is far prettier than the regular float:

             {
        "<leader>fe",
        function()
          local harpoon = require("harpoon")
          local fzf = require("fzf-lua")
          local list = harpoon:list()
          local items = {}
          for i = 1, list:length() do
            local item = list:get(i)
            if item and item.value and item.value ~= "" then
              table.insert(items, string.format("%d: %s", i, item.value)) -- skip empty lines if deletion didn't functional properly
            end
          end
          fzf.fzf_exec(items, {
            prompt = "Harpoon Files> ",
            winopts = {
              width = 0.4,
              height = 0.4,
            },

            fzf_opts = {
              ["--preview"] = "bat --style=numbers --color=always $(echo {} | sed 's/^\\([0-9]\\+\\): //')",
            },
            actions = {
              ["default"] = function(selected)
                local idx = tonumber(selected[1]:match("^(%d+):"))
                if idx then
                  list:select(idx)
                end
              end,
              ["ctrl-d"] = function(selected)
                local idx = tonumber(selected[1]:match("^(%d+):"))
                if idx then
                  local item = list:get(idx)
                  list:remove(item)
                end
              end,
            },
          })
        end,
        desc = "Harpoon FZF Menu",
      },

Is this something you would be interested in adding to your readme or fzf-lua itself?

That’s great @stuckinsnow! I think the best place for this is the Wiki, it’s open edit you can add it yourself if you wish :)

Thanks for the fast reply. Done!

Great initiative, I've actually started working on this yesterday but adding a picker for it (probably overkill). I came to the discussions section to ask a question to unblock me and I'm glad I saw this harpoon2 integration as the last posted item.

I have a small list of things I wanted to improve on the Harpoon UI which would benefit my workflow a lot:

• Fuzzy search (my main reason why integrating with fzf-lua).
• Showing the number at the start of the line, to make it easy to fuzzy find, like code actions. (Included in this solution).
• Showing dev-icons.

Preview for me is really not a must, but if I would include preview it would need to show the las position in the file, not the start of the file.

The solution I was working on adding a Harpoon picker is this one:
https://github.com/ibhagwan/fzf-lua/compare/main...carloscalla:fzf-lua:harpoon-integration?expand=1

Unfortunately so far this one goes to the beginning of the file because I wasn't using Harpoon's select method, I was trying to introduce that but was having trouble with it.

From your solution I'm only missing the dev-icons given that the preview is not really a priority for me to improve, just icon number and fuzzy search.

One more note, you can use harpoon:list():display() to get the list of files ready for display, already filtering '' empty lines.

This shouldn’t be hard @carloscalla, format your entire with icon<FzfLua.utils.nbps>file:line and you can use any of the file previewer in fzf-lua (builtin, bat, etc) with file location.
