다음은 dabbrev-expand를 확장하여 하위 문자열 확장을 지원하는 것입니다. 아는 한 예상대로 작동합니다. 그러나 심볼 내 확장을 mdabbrev과 비슷한 방식으로 지원하면 기호 문자 및 대소 문자 조정 지원 측면에서 불완전한 것으로 나타났습니다. 그러나 dabbrev-substring-search에 대한 pattern 인수는 점 이전의 패턴 일 뿐이지 만 내부 확장을 위해서는 점 다음에 패턴이 필요합니다. hippie/dabbrev-expand에서이 패턴을 사용할 수없는 이유는 무엇입니까?자리 표시 Word/Symbol Dabbrev 확장
