Using ack to search for regex in a specific file type

Question

Wondering if there's a way to look for something like ack foo "*.scss"

Answer 1

Generally ack uses predefined file types, so the pessimistic answer is "No". However, if you regularly search in .scss files, you may want to set it as a file type in your .ackrc by adding the following line:

--type-set=sassy=.scss

Answer 2

"*.scss" isn't a regex, but shell globbing.

Like voyager42 says about, use

--type-set=sassy=.scss

in your .ackrc and then you can do

ack foo --sassy

or if you do NOT want to search sassy files

ack foo --nosassy
