Features

• Works out of the box with a single require('mini.animate').setup(). No extra mappings or commands needed.
• Animate cursor movement inside same buffer by showing customizable path.
• Animate scrolling with a series of subscrolls ("smooth scrolling").
• Animate window resize by gradually changing sizes of all windows.
• Animate window open/close with visually updating floating window.
• Timings for all actions can be customized independently.
• Action animations can be enabled/disabled independently.
• All animations are asynchronous/non-blocking and trigger a targeted event which can be used to perform actions after animation is done.
• MiniAnimate.animate() function which can be used to perform own animations.

Notes:

• Although all animations work in all supported versions of Neovim, scroll and resize animations have best experience with Neovim>=0.9.
• Scroll and resize animations actually change Neovim state to achieve their effects and are asynchronous. This can cause following issues:
  • If you have remapped any movement operation to center after it is done (like with nzvzz or <C-d>zz), you need to change those mappings. Either remove them or update to use MiniAnimate.execute_after() (see :h MiniAnimate.config.scroll)
  • Using mouse wheel to scroll can appear slower or can have visual jitter. This usually happens due to high number of wheel turns per second: each turn is taking over previous one to start new animation. To mitigate this, you can either modify 'mousescroll' option (set vertical scroll to 1 and use high turn speed or set to high value and use one turn at a time) or config.scroll to fine tune when/how scroll animation is done.

Installation

This plugin can be installed as part of 'mini.nvim' library (recommended) or as a standalone Git repository.

There are two branches to install from:

• main (default, recommended) will have latest development version of plugin. All changes since last stable release should be perceived as being in beta testing phase (meaning they already passed alpha-testing and are moderately settled).
• stable will be updated only upon releases with code tested during public beta-testing phase in main branch.

Here are code snippets for some common installation methods (use only one):

With mini.deps

Github repo	Branch	Code snippet
'mini.nvim' library	Main	Follow recommended 'mini.deps' installation
	Stable
Standalone plugin	Main	add('echasnovski/mini.animate')
	Stable	add({ source = 'echasnovski/mini.animate', checkout = 'stable' })

With folke/lazy.nvim

Github repo	Branch	Code snippet
'mini.nvim' library	Main	{ 'echasnovski/mini.nvim', version = false },
	Stable	{ 'echasnovski/mini.nvim', version = '*' },
Standalone plugin	Main	{ 'echasnovski/mini.animate', version = false },
	Stable	{ 'echasnovski/mini.animate', version = '*' },

With junegunn/vim-plug

Github repo	Branch	Code snippet
'mini.nvim' library	Main	Plug 'echasnovski/mini.nvim'
	Stable	Plug 'echasnovski/mini.nvim', { 'branch': 'stable' }
Standalone plugin	Main	Plug 'echasnovski/mini.animate'
	Stable	Plug 'echasnovski/mini.animate', { 'branch': 'stable' }

Important: don't forget to call require('mini.animate').setup() to enable its functionality.

Note: if you are on Windows, there might be problems with too long file paths (like error: unable to create file <some file name>: Filename too long). Try doing one of the following:

• Enable corresponding git global config value: git config --system core.longpaths true. Then try to reinstall.
• Install plugin in other place with shorter path.

Default config

-- No need to copy this inside `setup()`. Will be used automatically.
{
  -- Cursor path
  cursor = {
    -- Whether to enable this animation
    enable = true,

    -- Timing of animation (how steps will progress in time)
    timing = --<function: implements linear total 250ms animation duration>,

    -- Path generator for visualized cursor movement
    path = --<function: implements shortest line path>,
  },

  -- Vertical scroll
  scroll = {
    -- Whether to enable this animation
    enable = true,

    -- Timing of animation (how steps will progress in time)
    timing = --<function: implements linear total 250ms animation duration>,

    -- Subscroll generator based on total scroll
    subscroll = --<function: implements equal scroll with at most 60 steps>,
  },

  -- Window resize
  resize = {
    -- Whether to enable this animation
    enable = true,

    -- Timing of animation (how steps will progress in time)
    timing = --<function: implements linear total 250ms animation duration>,

    -- Subresize generator for all steps of resize animations
    subresize = --<function: implements equal linear steps>,
  },

  -- Window open
  open = {
    -- Whether to enable this animation
    enable = true,

    -- Timing of animation (how steps will progress in time)
    timing = --<function: implements linear total 250ms animation duration>,

    -- Floating window config generator visualizing specific window
    winconfig = --<function: implements static window for 25 steps>,

    -- 'winblend' (window transparency) generator for floating window
    winblend = --<function: implements equal linear steps from 80 to 100>,
  },

  -- Window close
  close = {
    -- Whether to enable this animation
    enable = true,

    -- Timing of animation (how steps will progress in time)
    timing = --<function: implements linear total 250ms animation duration>,
