I have a script with which I toggle between a dark and a light colorscheme. The terminal emulator I use (termite) rereads its configuration when receiving the signal USR1, so when toggling my colorscheme I send USR1 to all termite instances so that the colorscheme is updated immediatly.
Does there exist some possibility to convince neovim to reread its configuration (from outside of neovim)?
I couldn't really find a list of what neovim makes of unix signals. It also doesn't need to be a signal, as far as I understand neovim has some concepts of "server" and "frontend", so I guess something like connecting to each server and issuing to reload the configuration would also work.
