Eovim is a client for Neovim written using the Enlightenment Foundation Library.

Eovim is written in plain C, with the amazing EFL, adding value to the
text-only neovim with a minimal runtime overhead. If you don't like the
externalized UI, it can be turned off, or changed via themes. Eovim also
provides its own plugin system, so the UI can be modified directly from neovim.
