This is a simple neovim plugin that helps keeping blocks of code and reusing them as needed.

Packer:

use({
    'FabrizioPerria/CodeBox.nvim',
    requires = {
        'nvim-lua/plenary.nvim',
        'nvim-telescope/telescope.nvim',
    }
})

N.B.: Remember to call require('codebox').setup({}).

Enter visual mode and select the snippet you wish to store. Then, run :CodeBox command; it will prompt for a snippet title so you can easily retrieve it later.

Run :CodeUnbox; you will get a telescope window asking to select the snippet. Pressing Enter will write the snippet in the line next to the cursor. Pressing <C-d>(insert mode) / d(normal mode) will delete the snippet.

I suggest to map those commands with keys; using whick_key you can map to something like:

...
["c"]
{
    ['B'] = { ':CodeBox<CR>', 'Store code snippet', mode = { 'x' } },
    ['b'] = { ':CodeUnbox<CR>', 'Restore code snippet', mode = { 'n' } },
}
...

This is my first plugin :) i know it's not optimized, but it does what i need it to do. Feel free to file issues and send suggestions if you want.
