Narrow helm-projectile-grep to specific file type

Question

I usually find myself when using helm-projectile-grep to narrow my search down to a specific file type.

For example: I do a search for "container" but only want to show the results in the .style files. I haven't been able to find if you can do this with helm-projectile-grep but it does seem like it should be possible.

Answer 1

It is possible with the helm-ag package, which passes every "--" prefixed field to ag as CLI arguments.

To filter by file type use its extension as an argument. So calling helm-projectil-ag with:

--style container

will do the trick.

Additional examples:

--hidden search-pattern

Will include hidden files during search for search-pattern

--ignore=*.html container

Will ignore all html files. Note that --ignore accepts glob pattern instead of regexp.

Requirement

To use helm-ag you should install ag, which is multi-platform, uses perl-like regexp by default and is way faster than grep.

Answer 2

Unlike RichieHH stated in a comment under atevm's answer in 2020, it now do work with helm-projectile-ag too

For example, I managed to search for a string in all php files with :

stringIsearchFor -G=*.php
