Dynamic height for bottom panel - buffers

[crates51]

Hello !

How would i be able to make the height of the bottom panel for buffers to be relative to the results inside, in my case the number of buffer

For now i use gb to open that panel, and i set the height to 0.15, i dont know how to make that automatic

This is my fzf-lua config:

return {
  "ibhagwan/fzf-lua",
  dependencies = { "kyazdani42/nvim-web-devicons" },
  config = function()
    local fzflua = require("fzf-lua")

    -- configure fzf-lua
    fzflua.setup({
      winopts = {
        preview = {
          layout = "vertical",
          flip_columns = 130,
          scrollbar = "float",
        },
      },
      fzf_opts = {
        ["--layout"] = "default",
      },
      files = {
        rg_opts = "--color=never --files --hidden --follow --no-ignore -g '!.git' -g '!vimlog' -g '!.mypy*' -g '!__pycache__' -g '!.pytest_cache'",
      },
      grep = {
        rg_opts = "--column --line-number --hidden --no-heading --color=always --hidden -g '!.git' -g '!vimlog'",
      },
      keymap = {
        fzf = {
          ["ctrl-q"] = "select-all+accept",
        },
      },
    })

    local keymap = vim.keymap -- for conciseness

    -- Keymap for searching text with ripgrep
    keymap.set("n", "<C-f>", "<cmd>lua require('fzf-lua').grep({ search = '' })<CR>", { desc = "Search" })
    keymap.set("n", "<space>l", "<cmd>lua require('fzf-lua').grep_last()<CR>", { desc = "Search Last Pattern" })

    -- Keymap for buffers with last-used buffer sorting and bottom positioning
    keymap.set("n", "gb", function()
      fzflua.buffers({
        sort_lastused = true, -- Sort buffers by last used
        ignore_current_buffer = true, -- Optionally ignore the current buffer
        previewer = false,
        winopts = {
          height = 0.15, -- Set the height to 25% of the screen
          width = 0.15,
          row = 1.0, -- Position it at the bottom
        },
      })
    end, { desc = "Fuzzy find buffers with last used sorting at the bottom" })
  end,
}

Thanks

Set height to an integer that’s equal to the number of buffers + borders, something like:

  height = #vim.api.nvim_list_bufs() + 2,

Note that to get an accurate count of the buffer list you’ll need to filter hidden and scratch buffers by iterating the output of the table.
