Graph-ReadWrite
This is a collection of perl classes for reading and writing
directed graphs in a variety of file formats. The graphs are
represented in Perl using Jarkko Hietaniemi's Graph classes.
Version 2+ of this distribution works with version 0.5 and
later of the Graph distribution.
There are two base classes:
Graph::Reader
Base class for classes which read a graph
file and create an instance of the Graph class.
Graph::Writer
Base class for classes which take an instance of the
Graph class and write it out in a specific file format.
This distribution also defines a simple XML format for storing
directed graphs, defined to meet the needs of the Graph class.
A reader and writer are provided for this:
Graph::Reader::XML
Graph::Writer::XML
Writers are also included for Dot, VCG, and daVinci,
two packages for displaying / rendering graphs.
Dot and VCG are freely available; daVinci is freely available
at the moment, but that is going to change soon.
Graph::Writer::Dot
Graph::Writer::VCG
Graph::Writer::daVinci
A reader for Dot files has been contributed by Mark Hillebrand:
Graph::Reader::Dot
A reader and writer for HTK lattices are also included:
Graph::Reader::HTK
Graph::Writer::HTK
These last two will probably only be of interest to people working
with HTK, or tools which use the same format.
Dependencies:
Graph Jarkko's Graph classes
XML::Parser used by Graph::Reader::XML
XML::Writer used by Graph::Writer::XML
IO::File
To install these modules, you should just have to run the following:
% perl Makefile.PL
% make
% make test
% make install
This distribution contains an early version of a test-suite;
you may get a warning about an undefined value from one of the tests.
Bugs, suggestions, and new readers and writers will be gratefully received.
