neovim

[fit] What's wrong with vim?

  • Nothing!
  • over 20 years old
  • 300K lines of "scary" C89 code
  • All code is Bram Mooleaner's responsibility
  • Lots of platform-specific code
  • All plugin code runs synchronously

left filtered

[fit] What does neovim do better?

  • Aggressively refactor source code1
    • Replace platform-specific code with libuv
    • Simplify maintenance
  • Split work between multiple developers
  • Provide a new plugin architecture based on coprocesses
    • Plugins can be written in any language without explicit support from the editor

Similar to vundle, but super-fast!

call plug#begin('~/.vim/plugged')

Plug 'tpope/vim-fugitive'
Plug 'tpope/vim-repeat'
Plug 'garbas/vim-snipmate'

" On-demand loading
Plug 'scrooloose/nerdtree', { 'on':  'NERDTreeToggle' }

" Unmanaged plugin (manually installed and updated)
Plug '~/my-prototype-plugin'

" Add plugins to &runtimepath
call plug#end()

There's more!
