DESCRIPTION ^

This script offers a shell-level interface to the Term::Clui CPAN-module. The first argument is the question; by default, subsequent arguments are offered as choices; with the -f (Filter) option, the lines of STDIN are offered as the choices.

For the user, it uses the Arrow-keys and Return, or q to quit. If a -m multiple-choice is being offered, then SpaceBar highlights choices additional to the one under the final Return.

This program comes packaged with the Term::Clui module, in the examples/ directory.

OPTIONS ^

-f

Causes choose to work as a filter (like grep), so that the user chooses between lines from the standard input. (The default is that the user chooses between the 2nd and all subsequent arguments.)

-m

This offers multiple-choice; the equivalent of calling Term::Clui::choose in a list context.

-v

Prints version number.

CHANGES ^
