Overview

Generates the WHATWG “component pattern string” returned by the component getters (protocol, hostname, pathname, …). It parses the raw component pattern into a part list — applying the same per-component canonicalization used for matching — and re-serialises it (“generate a pattern string”), so wildcards become “*”, hostnames are punycoded, fixed text is percent-encoded, redundant “{}” groups are dropped, and so on.

This is a port of the path-to-regexp-derived parse()/partsToPattern() used by the reference URLPattern implementation.

".*"
IDENTIFIER_PART =

Identifier continuation code points. The reference uses /[$_‌‍pID_Continue]/u; in Ruby “_”, ZWNJ and ZWJ are already in pID_Continue, so only “$” needs to be added (avoids a duplicate-range warning).

/[$\p{ID_Continue}]/u
