Text::Tabs.3perl

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 $_'
