// Package confirm provides an interface to ask a user to confirm an action.
|
|
// The user is provided with an interface to choose an affirmative or negative
|
|
// answer, which is then reflected in the exit code for use in scripting.
|
|
//
|
|
// If the user selects the affirmative answer, the program exits with 0. If the
|
|
// user selects the negative answer, the program exits with 1.
|
|
//
|
|
// I.e. confirm if the user wants to delete a file
|
|
//
|
|
// $ gum confirm "Are you sure?" && rm file.txt
