Experimental keycast plugin for Vim/Neovim

Overview

vim-keycasty

demo

Introduction

Keycasty is an experimental keycast plugin for Vim/Neovim.

Still work in progress. Use it just for testing.

Design

  • Keycasty estimates key inputs from each event (cursor movement, text modification, etc.), rather than watching real key inputs, which is not possible on Neovim
  • Keycasts are shown beside the cursor, so that one can follow both of cursor movement and keycasts easily

Limitations

  • Keycasts from the plugin are not necessarily identical with true key inputs
  • Events other than cursor movement are not supported yet
  • Custom key mappings are not supported yet

Dependency

  • Vim (v8.2.3995+) or Neovim (v0.6.1+)
  • Deno (v1.21.0+)
  • denops.vim (v3.0.0+)

Installation

  1. Install Deno
  2. Install denops.vim and vim-keycasty with your package manager

Example: vim-plug

Plug 'vim-denops/denops.vim'
Plug 'hasundue/vim-keycasty'

Configuration

Keycasty refers the updatetime value for the time for which the pop-up automatically disappears if no input is received.

Set it as an appropriate value like 1000 ms, but notice that this may affect behavior of the editor or other plugins.

Example:

set updatetime=1000

:KeycastyEnable

Enable keycasty in all buffers.

:KeycastyDisable
