Data::LineBuffer for Linux 0.01

Data::LineBuffer is a Perl module that provides a very rudimentary input push back facility. It provides a layer between the input source and the calling routine which allows data to be pushed back onto the input source for retrieval, as a last in, first out, stack.<br /><br />It is only concerned with line-oriented data, and can interface with a filehandle, a subroutine (which returns data), a string containing multiple lines to be parsed, or an array of lines. In order to provide a uniform interface, all returned input is chomp()'d.<br /><br />As an example, consider the following code:<br /><br /> use Data::LineBuffer;<br /><br /> my $src = new Data::LineBuffer "Line 1<br />Line 2<br />Line 3<br />Line 4<br />";<br /><br /> print $src->get, "<br />";<br /> print $src->get, "<br />";<br /> $src->unget( "Oh Happy Day!" );<br /> $src->unget( "I Sing with Joy!" );<br /> print $src->get, "<br />";<br /> print $src->get, "<br />";<br /> print $src->get, "<br />";<br /><br />This produces the following output:<br /><br /> Line 1<br /> Line 2<br /> I Sing with Joy!<br /> Oh Happy Day!<br /> Line 3<br /> Line 4
