Castabout is an example Neovim plugin to search through a buffer. You should probably use Telescope instead. Castabout is a simple demonstratation of a basic Neovim plugin in Lua.

Castabout optionally depends on dressing.nvim for fancy UI.

Install the plugin using your favorite package manager. For example, with Packer:

return require('packer').startup(function(use)
  use({
    'https://github.com/nat-418/castabout.nvim',
    requires = 'https://github.com/stevearc/dressing.nvim'
  })
end)

There is no configuration. Just use :Castabout forwards or :Castabout backwards to search like / or ?.

You could override default keymaps like this, but probably should not:

-- Use Castabout in normal and visual modes using / and ? keys
vim.keymap.set({'n', 'v'}, '/', '<Cmd>Castabout forwards<CR>')
vim.keymap.set({'n', 'v'}, '?', '<Cmd>Castabout backwards<CR>')
