Question

Trying to use Term::ANSIMenu to build a nice menu.

The doc says items() expects an array of arrays:

items()

Type: array of arrays
Constraints: [[<keyname>, <string>, <code_ref>], ...]
Default: []

So this works fine:

my $menu = Term::ANSIMenu->new(
    items  => [['1', 'First menu item', \&exec_item],
               ['2', 'And so on', \&exec_item],
              ]) ;

What I need to do is feed items() with strings in an existing array (that gets dynamically created by my program – it may contain any number of strings).

e.g.

@array = ('menu choice one', 'menu choice two', 'menu choice three') ;

I’m struggling to create an “array of arrays” that I can then pass to items().

Any takers?

Answer 1

You need to pass reference to array

Should looks like:

@array = (['1', 'First menu item', \&exec_item]); 
push @array, ['2', 'And so on', \&exec_item];

my $menu = Term::ANSIMenu->new(items => \@array);
