Question

This works:

#!/usr/bin/env perl
use warnings;
use 5.012;
use Curses;

initscr();

addstr( 5, 5, 'Hello, World!' );

refresh();
sleep 2;
endwin();

but if I add an attribute to the “addstr”-function it doesn’t work any more:

addstr( 5, 5, 'Hello, World!', A_BOLD );

What do I need to change, to get a bold “Hello World”?

Answer 1

addstr() doesn’t accept attributes. Use attron() / attroff() instead:

attron(A_BOLD);
addstr(5, 5, 'Hello, world!');
attroff(A_BOLD);
