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 $_'
