nvim-libmodal

This is a rewrite of vim-libmodal using Neovim's Lua API. This project aims to be cross-compatable with vim-libmodal— with a few notable exceptions (see the FAQ).

Installation

Either use packadd or any package manager. I recommend using lazy.nvim.

Requirements

  • Neovim 0.7+.
  • vim-libmodal is not installed.

Examples

lazy.nvim

{'Iron-E/nvim-libmodal',
  lazy = true, -- don't load until necessary
  version = '^3.0', -- OPTIONAL: unsubscribe from breaking changes
},

packer.nvim

return require('packer').startup {function(use)
  use 'Iron-E/nvim-libmodal'
end}

Usage

The following plugins have been constructed using nvim-libmodal:

Statusline

You can add libmodal modes to your status line. Here are a few examples of how to integrate with existing plugins.
