Version 1.11 of package Ack has just been released in GNU ELPA. You can now find it in M-x list-packages RET.
Ack describes itself as: =========================== interface to ack-like tools =========================== More at https://elpa.gnu.org/packages/ack.html ## Summary: ============================================================== The Simple Emacs Interface to `Ack <http://beyondgrep.com>`_-like Tools ============================================================== .. image:: https://elpa.gnu.org/packages/ack.svg :target: https://elpa.gnu.org/packages/ack.html :alt: GNU ELPA package This package integrates `ack <http://beyondgrep.com>`_ with `Emacs <http://www.gnu.org/software/emacs>`_. The resulting ``*ack*`` buffer is just like vanilla ``*grep*`` but results come from your tool of choice. Not only ack, but Ack-like tools such as `the silver searcher (ag) <https://github.com/ggreer/the_silver_searcher>`_, `ripgrep (rg) <https://github.com/BurntSushi/ripgrep>`_ are well supported, as are ``git grep`` and ``hg grep``. ## Recent NEWS: [Not provided 🙁]
