Module: RedQuilt::Slug

Defined in:
lib/red_quilt/slug.rb

Overview

Heading-anchor slugs, following GitHub’s github-slugger approach: downcase, strip punctuation, spaces to hyphens – but keep Unicode letters/marks/numbers verbatim, so Japanese (and other non-ASCII) headings survive instead of collapsing to empty ids.

STRIP_RE =

Drop anything that is not a letter, mark, number, underscore, space, or hyphen. Browsers percent-encode non-ASCII fragment ids on the wire but resolve and display them fine, matching GitHub.
