(From the Perl FAQ)

How do I expand tabs in a string?

You can do it yourself:

Code

    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).

Code

    use Text::Tabs; 
    @expanded_lines = expand(@lines_with_tabs);
