NeoZoom.lua

NeoZoom.lua helps you focus... and maybe protect your left-rotated neck.

DEMO

show-off.mov

How it works

The idea is simple: toggle your current window into a floating one, so you can:

  1. Focus on one of your windows without mess-up any of your tabpages(=window layouts).
  2. Pre-define a window layout for each list of filetypes. Now you can use the same keymap to have a customized window layout depending on the filetype of the current buffer.

(The original idea of this project can be found at branch neo-zoom-original)

Features

  • Only one function neo_zoom().
    • setup.winopts will be picked up if no match against setup.presets[i].filetypes.
    • setup.presets[n] will be picked up, otherwise.
    • setup.callbacks are always called, regardless of setup.presets[i].filetypes.
  • Some APIs to help you do customization:
    • M.did_zoom(tabpage=0) by passing a number tabpage, you can check for whether there is zoom-in window on the given tabpage.

Setup

NOTE: remove use if you're using lazy.nvim.

use {
  'nyngwang/NeoZoom.lua',
  config = function ()
    require('neo-zoom').setup {
      popup = { enabled = true }, -- this is the default.
      -- NOTE: Add popup-effect (replace the window on-zoom with a `[No Name]`).
      -- EXPLAIN: This improves the performance, and you won't see two
      --          identical buffers got updated at the same time.
      -- popup = {
      --   enabled = true,
      --   exclude_filetypes = {},
      --   exclude_buftypes = {},
      -- },
      exclude_buftypes = { 'terminal' },
      -- exclude_filetypes = { 'lspinfo', 'mason', 'lazy', 'fzf', 'qf' },
      winopts = {
        offset = {
          -- NOTE: omit `top`/`left` to center the floating window vertically/horizontally.
          -- top = 0,
          -- left = 0.17,
          width = 150,
          height = 0.85,
        },
        -- NOTE: check :help nvim_open_win() for possible border values.
        border = 'thicc', -- this is a preset, try it :)
      },
      presets = {
        {
          -- NOTE: regex pattern can be used here!
          filetypes = { 'dapui_.*', 'dap-repl' },
          winopts = {
            offset = { top = 0.02, left = 0.26, width = 0.74, height = 0.25 },
          },
        },
        {
          filetypes = { 'markdown' },
          callbacks = {
            function () vim.wo.wrap = true end,
          },
        },
      },
    }
    vim.keymap.set('n', '<CR>', function () vim.cmd('NeoZoomToggle') end, { silent = true, nowait = true })
  end
}

Bonus: transparent bg when unfocus

Thanks for the support from the upstream, i.e. neovim/neovim#23542 :)

    then for z, _ in pairs(zoom_book) do vim.wo[z].winbl = 0 end
