Go read about the Rob Pike's sam editor (such as http://doc.cat-v.org/plan_9/4th_edition/papers/sam/) and prepare to have your mind blown :)

Also read Rob’s Structured Regular Expressions paper which has more details on using REs for describing the *structure* of a piece of text rather than its content: https://doc.cat-v.org/bell_labs/structural_regexps/se.pdf
