Example document:


% turning off syntax highlighting:

foreach $l (@ll) {
  print "$l\n";

>From file:

Listing file example.lst with some markup:

foreach $l (@ll) {
  print "$l\n";
our $var1;
my $var2;

print "$var1\n"if defined $var1;
print "$var2\n"if defined $var2;

print "$var1\n"if /+defined $var1;+/
print "$var2\n"if defined $var2;

Somehow, replacing \itshape with \bfseries did not work.
