alternative to Emacs' isearch with an overview
Swiper gives an overview of the current regex search candidates. The search regex can be split into groups with a space. Each group is highlighted with a different face. . It can double as a quick regex-builder; however, only single lines will be matched. Swiper uses Ivy to show an overview of all matches.
