An Emacs front-end for ack

Build Status

ack is a tool like grep, aimed at programmers with large trees of heterogeneous source code. It is available at

Add the following to your .emacs:

(add-to-list 'load-path "/path/to/full-ack")
(autoload 'ack-same "full-ack" nil t)
(autoload 'ack "full-ack" nil t)
(autoload 'ack-find-same-file "full-ack" nil t)
(autoload 'ack-find-file "full-ack" nil t)

Run ack to search for all files and ack-same to search for files of the same type as the current buffer.

next-error and previous-error can be used to jump to the matches.

ack-find-file and ack-find-same-file use ack to list the files in the current project. It's a convenient, though slow, way of finding files.
