Equivalent to clojure.core/re-find, but returns the result of calling re-groups-ncg when the pattern is found, or nil otherwise.

If multiple finds are being performed, the versions where the sequence of named-capturing groups is passed in may be more efficient as they allow the caller to calculate the named-capturing groups in the regex once, then reuse that information, potentially avoiding re-parsing of the regex on each call.

Equivalent to clojure.core/re-groups, but instead of returning a sequence containing the entire match and each group, it returns a map of the named-capturing groups as well as the start index (:start), end index (:end), and text (:match) of the entire match.

The key for each named-capturing group that’s found is the (String) name of that group, and the corresponding value is the (String) text that matched that group.

If the same regex is being used many times, the 2-arg version may be more efficient as it allows the caller to calculate the named-capturing groups in the regex once, then reuse that information, potentially avoiding re-parsing of the regex on each call.

Equivalent to clojure.core/re-matches, but returns the result of calling re-groups-ncg when there’s a match, or nil otherwise.

If the regex is being reused many times, the 3-arg version may be more efficient as it allows the caller to calculate the named-capturing groups in the regex once, then reuse that information, potentially avoiding re-parsing of the regex on each call.

Returns the names of all of the named-capturing groups in the given regular expression (java.util.regex.Pattern) or matcher (java.util.regex.Matcher) as a set of Strings, or an empty set if there aren’t any.

Note: on older JDKs (pre v20), this uses a JDK-agnostic workaround for JDK-7032377.

Equivalent to clojure.core/re-seq, but returns the result of calling re-groups-ncg on each successive match, or nil if there are no matches.

If the regex is being reused many times, the 3-arg version may be more efficient as it allows the caller to calculate the named-capturing groups in the regex once, then reuse that information, potentially avoiding re-parsing of the regex on each call.
