Pgrepper

#+TITLE: Pgrepper: (Peco|Powerful|Parallel) Grepper

• (Peco|Powerful|Parallel) Grepper This tiny Ruby script enables narrowing by multiple grep(s). It aims to enhance [[https://github.com/peco/peco][peco]] as a custom filter, but you can use it anywhere. It is based on searcher of Emacs's incremental completion and selection narrowing framework, [[https://github.com/emacs-helm/helm/][helm]] (helm-multi-match) and [[http://repo.or.cz/anything-config.git][anything]] (anything-match-plugin).
