Hi all I have a big PCRE regex, that have conditional named groups. I want to reference all of the groups, even if match didn't occur and handle it on my side with simple if or something like this.
As nre [documentation](https://nim-lang.org/docs/nre.html) states: captures[]: string the string value of whatever was captured at that id. If the value is invalid, then behavior is undefined. If the id is -1, then the whole match is returned. If the given capture was not matched, nil is returned. "abc".match(re"(\w)").get.captures[0] == "a" "abc".match(re"(?<letter>\w)").get.captures["letter"] == "a" "abc".match(re"(\w)\w").get.captures[-1] == "ab" Run I can do that and get nil, if pattern was not matched. But actual nre code contains this: func checkNamedCaptured(pattern: RegexMatch, name: string): void = if not (name in pattern.captureBounds): raise newException(KeyError, "Group '" & name & "' was not captured") ... func `[]`*(pattern: Captures, name: string): string = let pattern = RegexMatch(pattern) checkNamedCaptured(pattern, name) return pattern.captures[pattern.pattern.captureNameToId[name]] Run Which throws error if named group was not matched.
