Text::Tabs -- expand and unexpand tabs per the unix expand(1) and unexpand(1)
=head1 SYNOPSIS
use Text::Tabs;
$tabstop = 4; # default = 8
@lines_without_tabs = expand(@lines_with_tabs);
@lines_with_tabs = unexpand(@lines_without_tabs);
=head1 DESCRIPTION
Text::Tabs does about what the unix utilities expand(1) and unexpand(1)
do. Given a line with tabs in it, expand will replace the tabs with
the appropriate number of spaces. Given a line with or without tabs in
it, unexpand will add tabs when it can save bytes by doing so (just
like C<unexpand -a>). Invisible compression with plain ASCII!
=head1 EXAMPLE
#!perl
# unexpand -a
use Text::Tabs;
while (<>) {
print unexpand $_;
}
Instead of the C<expand> comand, use:
perl -MText::Tabs -n -e 'print expand $_'
Instead of the C<unexpand -a> command, use:
perl -MText::Tabs -n -e 'print unexpand $_'
