68 own methods · 12 forms written with extensions, listed under their method

the source: base/regex/stzRegexMaker.ring(opens in a new tab) · All classes · The area reference: Pattern matching

Under each method, its extensions (Q CS XT Z ZZ IB W U): bold and ticked, it exists; struck, it does not. The extensions and what they mean

Examples: 5 come from the library's tests; 12 were composed from each method's signature and run for this page, on a fresh object, for example o1 = new stzRegexMaker() o1.AddWordBoundary(:start) o1.AddCapturingGroup("digits", "\d+") o1.AddWordBoundary(:end). 51 methods have none yet. Examples run on 2026-10-04 07:31 inside the library at commit 0e72e2e2c.
