Promptui is a library providing a simple interface to create command-line prompts for go. It can be easily integrated into spf13/cobra, urfave/cli or any cli go application.
Promptui has two main input modes:
-
Promptprovides a single line for user input. Prompt supports optional live validation, confirmation and masking the input. -
Selectprovides a list of options to choose from. Select supports pagination, search, detailed view and custom templates.
For a full list of options check GoDoc.
