Remove nix-mode.el from Nix.
This removes the file nix-mode.el from Nix. The file is now available within the repository https://github.com/NixOS/nix-mode. Fixes #662 Fixes #1040 Fixes #1054 Fixes #1055 Closes #1119 Fixes #1419 NOTE: all of the above should be fixed within NixOS/nix-mode. If one of those hasn’t please reopen within NixOS/nix-mode and not within NixOS/nix.

The Nix Emacs mode supports syntax highlighting, somewhat sensible
|
||||
indenting, and refilling of comments.
|
||||
|
||||
To enable Nix mode in Emacs, add something like this to your ~/.emacs
|
||||
file:
|
||||
|
||||
(load "/nix/share/emacs/site-lisp/nix-mode.el")
|
||||
|
||||
This automatically causes Nix mode to be activated for all files with
|
||||
extension `.nix'.
