BBEdit / BBEdit-Lite / TextWrangler Regular Expression Guide              Modified: 2018/08/10 01:19
————————————————————————————————————————————————————————————————————————————————————————————————————

NOTES: 

The PCRE engine (Perl Compatible Regular Expressions) is what BBEdit and TextWrangler use.

Items I'm unsure of are marked '# PCRE?'.  The list while fairly comprehensive is not complete.

Finding the Simulator

You can test with the iOS Simulator that comes with Xcode. Navigate to the Xcode app in the Finder, right click and select "Show Package Contents":

Then navigate to Contents > Applications, and open the shortcut to "iPhone Simulator" (it may be called "iOS Simulator" depending on which version of Xcode you're running):

Open Source code doesn’t always come in big complex packages. At ProPublica we sometimes share small, simple snippets of using GitHub "Gists." These Gists range from single-byte file delimiters to an entire JavaScript framework for making stepper graphics. They rarely have documentation and don’t even always have names, but they can be super-useful. Here are some we’ve shared over the past few years:

• A simple way to grab remote template elements in your Rails app (after Brian Boyer's RemoteSnippets) https://gist.github.com/1664329
• A single byte gist that contains ASCII character 28, which the FEC uses as a field delimiter. https://gist.github.com/2191300
• A [quine](http://en.wikipedia.org/wiki/Quine_(computing) in Ruby https://gist.github.com/523940
