Text::Tabs - phpMan

NAME
    Text::Tabs - expand and unexpand tabs like 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 most of what the unix utilities expand(1) and
    unexpand(1) do. Given a line with tabs in it, "expand" replaces those
    tabs with the appropriate number of spaces. Given a line with or without
    tabs in it, "unexpand" adds tabs when it can save bytes by doing so,
    like the "unexpand -a" command.

    Unlike the old unix utilities, this module correctly accounts for any
    Unicode combining characters (such as diacriticals) that may occur in
    each line for both expansion and unexpansion. These are overstrike
    characters that do not increment the logical position. Make sure you
    have the appropriate Unicode settings enabled.

EXPORTS
    The following are exported:

    expand
    unexpand
    $tabstop
        The $tabstop variable controls how many column positions apart each
        tabstop is. The default is 8.

        Please note that "local($tabstop)" doesn't do the right thing and if
        you want to use "local" to override $tabstop, you need to use
        "local($Text::Tabs::tabstop)".

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

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

    Instead of the shell's "expand" command, use:

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

    Instead of the shell's "unexpand -a" command, use:

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

SUBVERSION
    This module comes in two flavors: one for modern perls (5.10 and above)
    and one for ancient obsolete perls. The version for modern perls has
    support for Unicode. The version for old perls does not. You can tell
    which version you have installed by looking at $Text::Tabs::SUBVERSION:
    it is "old" for obsolete perls and "modern" for current perls.

    This man page is for the version for modern perls and so that's probably
    what you've got.

BUGS
    Text::Tabs handles only tabs ("\t") and combining characters ("/\pM/").
    It doesn't count backwards for backspaces ("\t"), omit other
    non-printing control characters ("/\pC/"), or otherwise deal with any
    other zero-, half-, and full-width characters.
