Cookbook: Standalone executable zip - ShuaiYAN/ipython GitHub Wiki

[Contributed].

With the code below, you can make a standalone executable zip file that contains all of IPython. The code as written is made for 0.10, but it's easy enough to adapt (we'll likely include it in IPython proper as a utility). If you update the library layout for the post-0.10 refactoring, please post an updated version below.
