Turning emacs into a Python IDE

## Create a new config/initialisation file

Create a user-level initialisation file init.el:

touch .emacs.d/init.el

pesterhazy

Consider this ClojureScript code:

(defn foo []
  (let [location 12345] (prn js/location.hash)))

This won't work. js/ isn't a real namespace. This code will throw an exception at runtime.

The reason is that the code expands to this JS snippet:

gonewest818

(setq lexical-binding t)

(defun cider-eval-pprint-to-multiline-comment-handler (buffer location arrow-prefix comment-prefix)
  "Make a handler for evaluating and printing commented results in BUFFER.
LOCATION is the location at which to insert.
COMMENT-PREFIX is the comment prefix to use."
  (cl-flet ((multiline-comment-handler (buffer value)
             (with-current-buffer buffer
               (save-excursion

Google Protobuf 3.0.1 - Mac OS X and iOS Support

The script in this gist will help you buid the Google Protobuf library for use with Mac OS X and iOS. Other methods (such as homebrew or direct compilation) have issues that prevent their use. The libraries built by this script are universal and support all iOS device architectures including the simulator.

This gist was adapted from the original at https://gist.github.com/BennettSmith/7150245, and updated to deal with Xcode 7 and iOS 9, and download protobuf version 3.0.0.
