If you're using Emacs with consult-ripgrep (M-x consult-ripgrep), you might want to search only within certain file types—say, just .scala files in a project. Here's the trick:

M-x consult-ripgrep RET -- -g '*.scala'

• The -- separates ripgrep (rg) options from the search term.
• -g '*.scala' tells rg to search only in .scala files.
• You can add multiple -g flags for different file types like below.

M-x consult-ripgrep RET -- -g '*.scala' -g '*.sbt'
