Code below produces the following output (escape sequence appearing as string): 'a ^[[33YELLOW^[[0m word'

use Curses;
use Term::ANSIColor;

initscr();
addstr(stdscr, "a ".color('yellow')."YELLOW".color('reset')." word");
refresh();
getch();
endwin();

Implementing a parser, with the following code, will produce the desired effects but will be expensive. Not to mention I feel like I'm reinventing the wheel.

use Curses;
use Term::ANSIColor;

initscr();

start_color();
init_pair(1, COLOR_YELLOW, COLOR_BLACK);

formatted_text(stdscr, "a ".color('yellow')."YELLOW".color('reset')." 
+word");

refresh();
getch();
endwin();

sub formatted_text {
    my ( $win, $text ) = @_;

    # tokenize text on escape sequences
    foreach ( split(/(\e\[[^m]+m)/, $text) ) {
        # token starts with <ESC>, set attr and dont add text
        if ( /^\e/ ) {
            if ( $_ =~ quotemeta(color('yellow')) ) {
                attron(COLOR_PAIR(1));
            }
            elsif ( $_ =~ quotemeta(color('reset')) ) {
                attroff(COLOR_PAIR(1));
            }
            next;
        }
        addstr($win, $_);
    }
}
