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'.

"Major mode for editing Nix expressions.
The following commands may be useful:
'\\[newline-and-indent]'
Insert a newline and move the cursor to align with the previous
non-empty line.
'\\[fill-paragraph]'
Refill a paragraph so that all lines are at most `fill-column'
lines long. This should do the right thing for comments beginning
with `#'. However, this command doesn't work properly yet if the
comment is adjacent to code (i.e., no intervening empty lines).
In that case, select the text to be refilled and use
`\\[fill-region]' instead.
The hook `nix-mode-hook' is run when Nix mode is started.
