* norns etc

Three scripts useful for local development on norns (i.e., outside of the ~maiden~ web interface):

+ ~norns_shell~: Get a lua shell or supercollider shell on a norns from the command-line, similar to the shell in the maiden interface. This connects to the same websocket interface that ~maiden~ does.
  #+BEGIN_SRC sh
  # get a lua shell
  ./norns_shell
  ./norns_shell ws://norns.local:5555
  # get a supercollider shell
  ./norns_shell ws://norns.local:5556
  #+END_SRC
+ ~norns_upload~: Upload a file to norns over http, just like how ~maiden~ does it.
+ ~norns_load~: Activate a norns script already on the device with ~norns.script.load(...)~ on the lua interface.

~norns_shell~ requires nanomsg. ~norns_upload~ requires jq and curl. Install everything with ~sudo make install~.

There's an example in ~example/~ of a project with a Makefile that uploads and loads when ~M-x compile~'d in emacs. This piece of emacs lisp may be helpful if you'd like to ~C-c C-c~ instead.

#+BEGIN_SRC lisp
(defun recursive-upwards-compile ()
  (interactive)
  (if (string-prefix-p "make" compile-command)
      (let ((directory (locate-dominating-file default-directory "Makefile")))
	(when directory
	  (cd directory)
	  (compile compile-command)
	  (message directory)))
    (compile compile-command)))

(add-hook 'lua-mode-hook
	  (lambda ()
	    (local-set-key (kbd "C-c C-c") 'recursive-upwards-compile)))
#+END_SRC
