ChangeLog for Graph-ReadWrite

2.00 2005-jan-02 neilb

• made the changes needed to work with version 0.5 of Graph classes
• patch to Graph::Reader::Dot from Mark Hillebrand.
• fixed warnings "Using a hash as a reference is deprecated"
• added support for new Dot attributes to Graph::Reader::Dot
• node ids are now quoted in Graph::Writer::Dot, which means you can safely have space, ':', '-', and other interesting characters in node ids.

        Added XML::Parser and XML::Writer as dependencies in Makefile.PL.
        This was prompted by looking at testers.cpan.org, which has
        this distribution as failing.

        Graph::Writer::VCG - common attributes (label, color, and
        text color) weren't supported on edges.
        Bug and fix reported by Alexandre Cherif.

Added a basic test-suite.

Commented out debugging output in the HTK Writer. Sorry Phil!

1.04 2001-nov-11 neilb

        Added Graph::Reader::Dot, a reader for the Dot format
        contributed by Mark Hillebrand.

        Fixed a bug in Graph::Reader::XML, found by Mark Hillebrand.
        The reader would only cope with a single <attribute> element
        inside each graph, node or edge element.

        Changed contact email address to neil@bowers.com

1.03

Added reader and writer classes for HTK lattice files.

1.02

        Fixed a bug in the XML writer module - the way it was using
        XML::Writer caused STDOUT to be closed after you've written
        a graph. I consider it a bug in XML::Writer, but I was able
        to change the way Graph::Writer::XML uses that module.

        Basically it just means that we construct a new instance
        of XML::Writer every time we write out a graph. For most
        uses, this won't be a problem, but you'd notice a hit if
        you were creating the writer and then writing a lot of graphs.

        This was noticed by Mike Hayward <hayward@loup.net>

1.01

Added support for URL attribute on nodes in Dot.

Added support for almost all attributes understood by VCG.

        Added a rough cut at a Writer class for daVinci:
                Graph::Writer::daVinci

1.00 feb 2001 neilb

Initial release - has baseclass for Reader and Writer classes.

Reader and Writer for simple XML format.

Writers for Dot and VCG formats.
