You probably need to set your environment variable
and export it.  If you don't export a variable the
variable is not available to spawned processes.

I am unfamiliar with fish, but this is what the borne
shell needs:


DARCS_EDITOR=/usr/local/bin/nvim
export DARCS_EDITOR

or just

export DARCS_EDITOR=/usr/local/bin/nvim



This from "darcs help environment" (which is why you get nano):

DARCS_EDITOR, VISUAL, and EDITOR:
  To edit a patch description of email comment, Darcs will invoke an
  external editor.  Your preferred editor can be set as any of the
  environment variables $DARCS_EDITOR, $VISUAL or $EDITOR.
  If none of these are set, nano is used.  If nano crashes or is not
  found in your PATH, vi, emacs, emacs -nw and (on Windows) edit are
  each tried in turn.
