  2  erock's minimal config
  3  ======================
  4
  5  design goals:
  6    - single file
  7    - use native nvim features (>= v0.12)
  8    - use default keybindings unless painful otherwise
  9    - use built-ins unless painful otherwise
 10    - use default colorschemes
 11    - plugins must be integral to workflow
