If you are having trouble getting an editor to work right on your platform, Adobe has released Brackets.io as a cross-platform (i.e., works on Mac, Windows, etc.) text editor. I haven’t spent a lot of time on it, but it looks like it could be an easier way to manipulate text files. My goal for the book was to show that you can program your computer without buying or even downloading anything. However, it may be just a bit easier to use a text editor geared for writing code.
