How do I expand tabs in a string?
You can do it yourself:
1 while $string =~ s/\t+/' ' x (length($&) * 8 - length($`) % 8)/e;
Or you can just use the Text::Tabs module (part of the standard
+perl distribution).
use Text::Tabs;
@expanded_lines = expand(@lines_with_tabs);

and this from perlop: Occasionally, you can't use just a `/g' to get all the changes to
occur that you might want. Here are two common cases:
# put commas in the right places in an integer
1 while s/(\d)(\d\d\d)(?!\d)/$1,$2/g;
# expand tabs to 8-column spacing
1 while s/\t+/' ' x (length($&)*8 - length($`)%8)/e;
And this has been in the perl man page since perl1!
print "\et" x ($tab/8), ' ' x ($tab%8); # tab over
