Text::Wrap - line wrapping to form simple paragraphs


        use Text::Wrap

        print wrap($initial_tab, $subsequent_tab, @text);
        print fill($initial_tab, $subsequent_tab, @text);

        use Text::Wrap qw(wrap $columns $huge);

        $columns = 132;
        $huge = 'die';
        $huge = 'wrap';


Text::Wrap::wrap() is a very simple paragraph formatter. It formats a single paragraph at a time by breaking lines at word boundaries. Indentation is controlled for the first line ($initial_tab) and all subsequent lines ($subsequent_tab) independently.

Lines are wrapped at $Text::Wrap::columns columns. $Text::Wrap::columns should be set to the full width of your output device.

When words that are longer than $columns are encountered, they are broken up. Previous versions of wrap() die()ed instead. To restore the old (dying) behavior, set $Text::Wrap::huge to 'die'.

Text::Wrap::fill() is a simple multi-paragraph formatter. It formats each paragraph separately and then joins them together when it's done. It will destroy any whitespace in the original text. It breaks text into paragraphs by looking for whitespace after a newline. In other respects it acts like wrap().


        print wrap("\t","","This is a bit of text that forms 
                a normal book-style paragraph");
