| Beschreibung |
This module implements the select loop of the "POSIX" shells (Bash, Korn, and
derivatives) for Perl. That loop is unique in two ways: it's by far the
friendliest feature of any UNIX shell, and it's the only UNIX shell loop
that's missing from the Perl language. Until now!
.
What's so great about this loop? It automates the generation of a numbered
menu of choices, prompts for a choice, proofreads that choice and complains if
it's invalid (at least in this enhanced implementation), and executes a
code-block with a variable set to the chosen value. That saves a lot of coding
for interactive programs -- especially if the menu consists of many values!
.
The benefit of bringing this loop to Perl is that it obviates the need for
future programmers to reinvent the Choose-From-A-Menu wheel.
