NAME

Text::Tabs -- expand and unexpand tabs per the unix expand(1) and unexpand(1)

SYNOPSIS

use Text::Tabs;

$tabstop = 4;  # default = 8
@lines_without_tabs = expand(@lines_with_tabs);
@lines_with_tabs = unexpand(@lines_without_tabs);

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 unexpand -a). Invisible compression with plain ASCII!

EXAMPLE

#!perl
# unexpand -a
use Text::Tabs;

while (<>) {
  print unexpand $_;
}

Instead of the expand comand, use:

perl -MText::Tabs -n -e 'print expand $_'

Instead of the unexpand -a command, use:

perl -MText::Tabs -n -e 'print unexpand $_'
