SUBROUTINES

banner(MESSAGE, FH)

Print a banner message on the supplied file handle (defaults to STDOUT)

banner( "Hello World" );
banner( "Hello World", $outputFH );

MESSAGE The message to display in the banner

FH is a file handle where the banner will be output, default: STDOUT

display_menu(MSG,ITEMS)

Display a simple menu of options. The choices come from an array. Returns the index of the choice.

MSG a string or variable containing the prompt message to display.

ITEMS a reference to an array of the choices to list

my $msg   = 'Pick one of the suits: ';
my @items = qw( hearts clubs spades diamonds );
display_menu( $msg, \@items );

yes_no_prompt(ARGS_HASH)

Prompt user for a yes or no response. Takes a single character for input, must be [yYnN\n]. A carriage return will return the default. Returns 1 for yes, 0 for no.

ARGS_HASH: { text => TEXT, default => DEFAULT_BOOL, prepend => PREPEND, append => APPEND }

TEXT The text of the prompt.

DEFAULT_BOOL Set the default response: 1 -> Yes ([Y]/N), 0 -> No (Y/[N]), undef -> none

PREPEND Text to prepend to TEXT

APPEND Text to append to TEXT

my $action = yes_no_prompt(
                       { text    => "Rename Files?",
                         default => 1,
                         prepend => '>' x 3,
                         append  => ': '
                       }
                     );

prompt(ARGS_HASH)

Prompt user for input.

ARGS_HASH: { text => TEXT, default => DEFAULT, valid => VALID, prepend => PREPEND, append => APPEND, noecho => ECHO_BOOL }

DEFAULT Set the default response, optionally.

VALID Ensures the response is valid. Can be a list or array reference, in which case the values will be presented as a menu. Alternately, it can be a code ref, where the subroutine is run with $_ set to the response. An invalid response will re-prompt the user for input.

ECHO_BOOL Normally (the default 0) text will be echoed as it is typed. If set to 1 text will not be echoed back to the screen.

my $interval = prompt(
                       { text    => "Move Files Daily or Monthly",
                         valid   => [ 'daily', 'monthly' ],
                         default => 'daily',
                         prepend => '> ' x 3,
                         append  => ': ',
                         noecho  => 0
                       }
                     );
my $dir = prompt(
                  { text    => "Enter Destination Dir",
                    valid   => \&dir_writable,
                    prepend => '<' x 3,
                    append  => ': '
                  }
                );
my $color = prompt(
                    { text    => "What is your favorite color",
                      prepend => '.' x 3,
                      append  => ': '
                    }
                  );

Note: The API for this function is maintained to support the existing code base that uses it. It would probably be better to use IO::Prompter for new code.
