accelerated-jk.nvim

This plugin accelerates j/k mappings' steps while j or k key is repeating. The original version is rhysd/accelerated-jk and now i rewrited it with Lua.

Requirements

• Neovim latest stable version or nightly

Installation

You can install accelerated-jk.nvim with your favorite package manager.

vim-plug:

Plug 'rainbowhxch/accelerated-jk.nvim'

packer.nvim:

use { 'rainbowhxch/accelerated-jk.nvim' }

Usage

After install, you can make acceleration work through mapping j/k to plugin's internal mappings.

vim.api.nvim_set_keymap('n', 'j', '<Plug>(accelerated_jk_gj)', {})
vim.api.nvim_set_keymap('n', 'k', '<Plug>(accelerated_jk_gk)', {})

All internal mappings here:

Mappings	Meaning
<Plug>(accelerated_jk_j)	accelerated j movement
<Plug>(accelerated_jk_k)	accelerated k movement
<Plug>(accelerated_jk_gj)	accelerated gj movement
<Plug>(accelerated_jk_gk)	accelerated gk movement

Modes

All modes acceleration step according to the setting acceleration_table.

• time_driven: The default one. With this mode, if the interval of key-repeat takes more than acceleration_limit ms, the step is reset. If you want to decelerate up/down moving by time instead of reset, set enable_deceleration to true. In addition, if you want to change deceleration rate, set deceleration_table to a proper value. Even better, you can accelerate other movements (such as w, b) through acceleration_motions.

• position_driven: Reset steps using only position determination. Not sensitive enough, the effect is not good as the time_driven mode. Note that acceleration_motions isn't supported by this mode.

Configuration

If you stasify the default configuration, nothing is need to changed. Otherwise you can call require('accelerated-jk').setup() to change the behavior of acceleration. The default configuration is:

require('accelerated-jk').setup({
    mode = 'time_driven',
    enable_deceleration = false,
    acceleration_motions = {},
    acceleration_limit = 150,
    acceleration_table = { 7,12,17,21,24,26,28,30 },
    -- when 'enable_deceleration = true', 'deceleration_table = { {200, 3}, {300, 7}, {450, 11}, {600, 15}, {750, 21}, {900, 9999} }'
    deceleration_table = { {150, 9999} }
})

All configuration is here:

Item	Value	Meaning
mode	'time_driven' or 'position_driven'	Acceleration modes
enable_deceleration	Boolean	Whether to enable deceleration
acceleration_motions	List	The additional accelerated motions for time_driven mode, such as {'w', 'b'}.
acceleration_limit	Integer	The accelerated limit for time_driven mode
acceleration_table	List	Indexs represent steps of j/k mappings, values represent required number of typing j/k to advance steps. In the case of {5, 15, 29}, if j is hited: 1)less than 5 times, the acceleration step is 1, 2)more than 5 times and less than 15 times, the acceleration steps is 2, 3)more than 15 times and less than 29 times, the acceleration steps is 3, 4)and after 29 j hits, the acceleration steps is 4.
deceleration_table	List	Every element is a pair which the first element is elapsed time after last j/k typed and the second element is the count to decelerate steps. In the case of {{200, 3}, {300, 7}}, if the elapsed time: 1)less than 200ms, the deceleration step is 1, 2)more than 200ms and less than 300ms, the deceleration steps is 3, 3)more than 300ms, then deceleration steps is 7.
