NAME

6       Term::Completion::Multi - read one line of user input with multiple
7       values
8

USAGE

10         use Term::Completion::Multi;
11         my $tc = Term::Completion::Multi->new(
12           prompt  => "Enter your first names: ",
13           choices => [ qw(Alice Bob Chris Dave Ellen Frank George Heidi Ida) ]
14         );
15         my @names = $tc->complete();
16         print "You entered: @names\n";

DESCRIPTION

19       Term::Completion::Multi is a derived class of Term::Complete. It allows
20       to enter one line with multiple choices from a list of choices,
21       delimited by a configurable delimiter character (typically one space).
22       The return value of the "complete()" method is the list of values.
23
24       See Term::Complete for details.
25
26   Configuration
27       Term::Completion::Multi adds one additional configuration parameter,
28       namely "delim". The default is one space. You can change this to e.g.
29       a comma character if you prefer the user to separate the choices with a
30       comma instead of a space:
31
32         my $tc = Term::Completion->new(
33           delim => ',',
34           ...
35
36   Validation
37       The input validation works very much like in Term::Completion. Here
38       however the input is first split upon the delimiter character, and then
39       each item is validated. Consecutive delimiter characters are treated as
40       one.  If any single validation fails, the entire input is cancelled. If
41       all items validate OK, then the return value is built by concatenating
42       the items returned from validation with the delimiter character.
43
44       If you don't like the above then you are free to write a class that is
45       derived from Term::Completion::Multi and overrides the "validate"
46       method.
