## About This Game
Copy Editor is an intricate puzzle game that teaches you Regular Expressions
(RegEx), commonly used in computer science and language theory. Build complex
rules that process and sanitize text for your wacky and demanding publishers
who perpetually find themselves in turmoil over comical errors that arise in a
variety of old manuscripts that need to be reprinted.

Like its spiritual predecessor, The Devil’s Calculator, no familiarity with
advanced or even intermediate concepts is assumed, rudiments are learned
through gentle tutorials but the focus is always on tactics and lateral
thinking. While you will no doubt learn valuable RegEx skills, it is primarily
used a pre-text for these sophisticated and rewarding logic puzzles. Game
mechanics permit such playful obstructions as a limited number of rules,
certain keyboard keys not working for particular levels, and an embellishment
of RegEx that extends to Natural Language Processing allowing you to
discriminate on criteria like sentiment analysis, stems and parts of speech.

Optimization is a big part of Copy Editor, and you can see how well you stack
up to others with detailed histograms of your performance, the number of rules
required to sanitize the text as well as the number of chars needed. In this
way it is similar to RegEx Golf but far more elaborate and nuanced, since text
replacement is of equal importance. A fully formed level editor will allow you
to pose your own challenges to the community.
