- 4. Some Stayed capturing: (…) escape: mods: i, g quantifier: *, +, ? alternatives: | match var.: $/ min. match. suffix: ??, *?, +?
- 5. Operators
- 6. Create A Regex rx/.../
- 7. It's The New qr// rx/.../
- 8. Apply Rx ~~,
- 9. Known Since 5.10 ~~,
- 10. Still Changing In 5.18 ~~,
- 11. Apply Rx ~~, no more =~
- 13. Rx Methods match comb subst
- 15. Operators m :s// s :ss///
- 16. Modifiers no x
- 17. Modifiers no x m s
- 18. Modifiers no s e x
- 19. Modifiers no s ee x
- 22. Modifiers ~~ m :P5 /.../
- 24. Match x Times :x(n)
- 25. Just nth Match :nth(n)
- 26. Search from Pos On :c(n) :continue(n)
- 27. Search Only On Pos :p(n) :pos(n)
- 28. Spaces Have Meaning :s :sigspace :ss :samespace
- 29. Like qw// Only Smarter :s :sigspace :ss :samespace
- 30. Lower Line Is For s/// :s :sigspace :ss :samespace
- 32. Modifiers :m :ignoremark :mm :samemark
