Re: How to split a string based on length or word boundary

As long as your text doesn't contain any single words longer than your width:

$s = 'A really long  string that I want to add to the awesome menu sys
+tem';;

print "| $_ |" for map substr( $_ . ' 'x16, 0, 16 ), $s =~ m[(.{1,16})
+\s+]g;;
| A really long    |
| string that I    |
| want to add to   |
| the awesome menu |

Brilliant++!

Just needs a couple of tweaks:

print "| $_ |\n" for map substr($_ . ' ' x 16, 0, 16), $s =~ m[(.{1,16
+})(?:\s+|$)]g;
#            ^^                                                       
+  ^^^^^^^^^

(Otherwise, the final word won’t be printed unless it happens to be followed by whitespace.)

Good point about the $++

The \n is provided by -l in my code.

As Athanasius pointed out above, you need to change that to:

print "| $_ |\n" for map substr( $_ . ' 'x$menuWidth, 0, $menuWidth ),
+ $text =~ m[(.{1,$menuWidth})(?:\s+|$)]g;
