Cinnamon Scroll 🌀

Smooth scrolling for ANY movement command (or string of commands) đŸ¤¯. A highly customizable Neovim plugin written in Lua which doesn't break the single-repeat "." command (unlike some other plugins) and supports scrolling over folds.

New Features:

  • Support for the go-to-definition and go-to-declaration builtin LSP functions đŸĨŗ🎉.
  • Smooth horizontal scrolling when view has shifted left or right.
  • Smooth scrolling for the scroll wheel.

đŸ“Ļ Installation

Just install with your favorite package manager and run the setup function.

Packer

use {
  'declancm/cinnamon.nvim',
  config = function() require('cinnamon').setup() end
}

Lazy

{
  'declancm/cinnamon.nvim',
  config = function() require('cinnamon').setup() end
}

⚙ī¸ Configuration

A settings table can be passed into the setup function for custom options.

Default Settings

-- KEYMAPS:
default_keymaps = true,   -- Create default keymaps.
extra_keymaps = false,    -- Create extra keymaps.
extended_keymaps = false, -- Create extended keymaps.
override_keymaps = false, -- The plugin keymaps will override any existing keymaps.

-- OPTIONS:
always_scroll = false,    -- Scroll the cursor even when the window hasn't scrolled.
centered = true,          -- Keep cursor centered in window when using window scrolling.
disabled = false,         -- Disables the plugin.
default_delay = 7,        -- The default delay (in ms) between each line when scrolling.
hide_cursor = false,      -- Hide the cursor while scrolling. Requires enabling termguicolors!
horizontal_scroll = true, -- Enable smooth horizontal scrolling when view shifts left or right.
max_length = -1,          -- Maximum length (in ms) of a command. The line delay will be
                          -- re-calculated. Setting to -1 will disable this option.
scroll_limit = 150,       -- Max number of lines moved before scrolling is skipped. Setting
                          -- to -1 will disable this option.

Example Configuration

require('cinnamon').setup {
  extra_keymaps = true,
  override_keymaps = true,
  max_length = 500,
  scroll_limit = -1,
}

⌨ī¸ Keymaps

Extra Keymaps

Smooth scrolling for ...

Start/end of line:          0, ^ and $
Paragraph movements:        { and }
Prev/next search result:    n, N, *, #, g* and g#
Prev/next cursor location:  <C-O> and <C-I>
Screen scrolling:           zz, zt, zb, z., z<CR>, z-, z^, z+, <C-Y> and <C-E>
Horizontal scrolling:       zH, zL, zs, ze, zh and zl

Extended Keymaps

Smooth scrolling for ...

Up/down movements:          [count]j, [count]k, [count]<Up> and [count]<Down>
Left/right movements:       [count]h, [count]l, [count]<Left> and [count]<Right>

ℹī¸ API

Scroll(arg1, arg2, arg3, arg4)
  • arg1 = A string containing the normal mode movement commands. Look at the 'Keymaps' section for examples.
    • To use the go-to-definition LSP function, use 'definition' (or 'declaration' for go-to-declaration).
  • arg2 = Scroll the window with the cursor. (1 for on, 0 for off). Default is 0.
  • arg3 = Accept a count before the command (1 for on, 0 for off). Default is 0.
  • arg4 = Length of delay between each line (in ms). Setting to -1 will use the 'default_delay' config value. Default is -1.

Note: When scrolling horizontally, the delay argument is halved so vertical and horizontal scrolling have similar speeds.

Custom Keymaps

Cinnamon will detect when a user has created their own keymaps for a command and will not replace it.

-- Activating Cinnamon:
require('cinnamon').setup { extra_keymaps = true }

-- Customizing keymaps that are part of the extra mappings:
vim.keymap.set('n', 'n', "<Cmd>lua Scroll('n')<CR>")
vim.keymap.set('n', 'N', "<Cmd>lua Scroll('N')<CR>")
