정규 표현식, 유니 코드 및 Javascript가있는 상황은 짜증납니다. 프로그래머가 "Αλφα"가 단어이거나 심지어 "é"가 문자임을 인식하기 위해 외부 라이브러리에 의존해야한다는 것은 우스운 일입니다.
그러나 그렇습니다.
이 사람은 Javascript Regexes에서 유니 코드를 처리하기위한 좋은 라이브러리를 작성했습니다.
http://blog.stevenlevithan.com/archives/javascript-regex-and-unicode
유니 코드 항목은이 정규식 라이브러리에 대한 플러그인입니다.
유니 코드 확장에 대한 게시물은 다음과 같습니다.
http://blog.stevenlevithan.com/archives/xregexp-unicode-plugin
그리고 확장 페이지 자체 :
대단한 일이지만 Javascript가 이와 관련하여 너무 뒤떨어져 있다는 것은 여전히 저를 울립니다.
(그는 주제에 관해 O'Reilly를 위해 책을 썼으므로 그가 말하는 것을 아는 것이 가능할 것입니다.)
그가 구현 한 방식은 특정 속성을 가진 문자표를 추가하는 것입니다. 그런 다음 라이브러리로 정규 표현식을 구성 \p{charclass}하면로 대체됩니다 [allthecharactersintheclass].
유니 코드 속성 이스케이프 는 ES2018의 기능 중 하나입니다.
유니 코드 속성 이스케이프를 사용하면 모든 언어의 문자를 다음과 같은 간단한 정규식과 일치시킬 수 있습니다.
/\p{Letter}/u또는 속기, 심지어 더 간결한 :
/\p{L}/u질문의 구체적인 사용 사례 (일치하는 단어), 당신은 문자 클래스에서 유니 코드 속성 탈출을 사용하여 쉽게 문자와 일치 할 수있게 할 수 있습니다에 대해서 함께 하이픈 같은 다른 워드 문자를 :
/[\p{L}-]/u이 모든 것을 하나로 묶으면 모든 [1] 언어의 단어 를이 짧은 짧은 RegEx와 일치시킬 수 있습니다.
/([\p{L}-]+)/ug예 ( 위의 답변 에서 뻔뻔하게 연결 ) :
'Düsseldorf, Köln, Москва, 北京市, إسرائيل !@#$'.match(/([\p{L}-]+)/ug)
// ["Düsseldorf", "Köln", "Москва", "北京市", "إسرائيل"][1] 나는 언어 전문가가 아닙니다. 글자와 하이픈 이외 의 단어의 일부일 수있는 다른 문자에 대한 자체 연구를 계속하고 싶을 수도 있습니다.
현재 (2018 년 12 월) Chrome (및 Opera, Vivaldi 또는 이후 버전의 Microsoft Edge와 같은 다른 Blink 기반 브라우저) 및 Safari (버전 12, 버전 11 이전 테스트)에서만이 정규식을 성공적으로 테스트 할 수있었습니다. 실패한). 그러나 사양이 완성되고 기능이 표준화되었으므로 다른 최신 브라우저도 곧 출시 될 것으로 예상됩니다.
브라우저가 유니 코드 속성 이스케이프를 지원하는지 확인하기 위해 작은 웹 사이트 를 만들었습니다 .
유니 코드 속성 탈출이라는 도구로 ES5까지 transpiled 할 수 regexpu . 온라인 데모가 여기 있습니다 . 데모에서 볼 수 있듯이 오늘날 비 라틴 문자를 다음과 같은 ES5 정규식과 일치시킬 수 있습니다.
