Documentation

Overview

Package filter provides a fuzzy searching text input to allow filtering a list of options to select one option.

By default it will list all the files (recursively) in the current directory for the user to choose one, but the script (or user) can provide different new-line separated options to choose from.

I.e. let's pick from a list of gum flavors:

$ cat flavors.text | gum filter
