It is comparable to Perl's L, however we can't use L because some versions will abort when some word to print exceeds the maximum length allowed. (Ticket #17141, fixed in Perl 5.8.0.) =head2 Functions =over 4 =cut # _tab_length ($TXT) # ------------------ # Compute the length of TXT, counting tab characters as 8 characters. sub _tab_length($) { my ($txt) = @_; my $len = length ($txt); $len += 7 * ($txt =~ tr/\t/\t/); return $len; } =item C Format C<@values> as a block of text that starts with C<$head>, followed by the strings in C<@values> separated by spaces or by C<"$eol\n$fill"> so that the length of each line never exceeds C<$max_len>. The C<$max_len> constraint is ignored for C<@values> items which are too big to fit alone one a line. The constructed paragraph is C<"\n">-terminated. =cut sub wrap($$$$@) { my ($head, $fill, $eol, $max_len, @values) = @_; my $result = $head; my $column = _tab_length ($head); my $fill_len = _tab_length ($fill); my $eol_len = _tab_length ($eol); my $not_first_word = 0; foreach (@values) { my $len = _tab_length ($_); # See if the new variable fits on this line. # (The + 1 is for the space we add i
