NAME

Text::Wrapper - Simple word wrapping routine

VERSION

This document describes version 1.02 of Text::Wrapper, released May 10, 2008.

SYNOPSIS

     require Text::Wrapper;
     $wrapper = Text::Wrapper->new(columns => 60, body_start => '    ');
     print $wrapper->wrap($text);
 
 

DESCRIPTION

Text::Wrapper provides simple word wrapping. It breaks long lines, but does not alter spacing or remove existing line breaks. If you're looking for more sophisticated text formatting, try the Text::Format module.

Reasons to use Text::Wrapper instead of Text::Format:

*

Text::Wrapper is significantly smaller.

*

It does not alter existing whitespace or combine short lines. It only breaks long lines.

Again, if Text::Wrapper doesn't meet your needs, try Text::Format.

Methods

$wrapper = Text::Wrapper->new( [options] )

Constructs a new Text::Wrapper object. The options are specified by key and value. The keys are:

  body_start  The text that begins the second and following lines of
              a paragraph.  (Default '')
 
  columns     The number of columns to use.  This includes any text
              in body_start or par_start.  (Default 70)
 
  par_start   The text that begins the first line of each paragraph.
              (Default '')
 
 

$wrapper->body_start( [$value] )

$wrapper->columns( [$value] )

$wrapper->par_start( [$value] )

If $value is supplied, sets the option and returns the previous value. If omitted, just returns the current value.

$wrapper->wrap($text)

Returns a word wrapped copy of $text. The original is not altered.

DEPENDENCIES

None.

INCOMPATIBILITIES

None reported.

BUGS AND LIMITATIONS

Does not handle tabs (they're treated just like spaces).

Does not break words that can't fit on one line.
