RSAVAGE / GraphViz-2.15 / Changes

Revision history for Perl module GraphViz.

2.15  Thu Nov 28 11:23:00 2013
	- Fix double-quote escaping bug in GraphViz's _attributes() method. See RT#90528.
		Many thanx to Smylers for the report.
	- Rename CHANGES to Changes as per CPAN::Changes::Spec.

2.14  Fri Nov  9 16:06:00 2012
	- No code changes.
	- Patch t/foo.t to not assume text appears on specific lines of the output test files.

2.13  Fri Nov  9 08:27:00 2012
	- No code changes.
	- Re-package distro because users get errors during testing. See RT#80709.
		Since I had this same error during my testing, I assume the uploaded version contains un-patched
		code. The errors are not in GraphViz, they are in the test code which has hard-coded line numbers
		where it looks for strings in the output. The output has been reformatted recently, and no longer
		matches those assumptions. See t/foo.t for details. Note: I did not write those tests :-).

2.12  Thu Nov  8 12:38:00 2012
	- No code changes.
	- For pre-reqs such as strict, warnings, etc, which ship with Perl, set the version # to 0.
		Reported as RT#80663 by Father Chrysostomos for Tree::DAG_Node.

2.11  Tue Sep 18 08:22:00 2012
	- Add VDX as an output format.

2.10  Mon Mar 26 10:11:00 2012
	- Accept a patch kindly supplied by Alexander Kriegisch, to change handling of the rankdir attribute.
		The valid values are BT, LR, RL or TB, or their lower-case equivalents.
		Previously, only a true value was accepted, which meant LR. Now, any value not in that list defaults to LR.
		Files changed: README, CHANGES, Changelog.ini, GraphViz.pm, GraphViz/Regex.pm and simple.t.
	- Patch this file to replace BST with GMT, since both DateTime::Format::HTTP and DateTime::Format::Strptime
		fail to recognize BST.
		These modules are used by Module::Metadata::Changes to transform this file into Changelog.ini.

2.09  Thu Dec 15 11:08:00 2011
	  - Adopt Flavio Poletti's suggestion of trying to pipe to dot, in Build.PL/Makefile.PL, rather than using File::Which,
	  	to see if dot (Graphviz) is installed. This (hopefully) solves the problem of using File::Which on systems where it is
		not installed, before Build.PL/Makefile.PL has a chance to tell the user that File::Which is required. See: RT#73077.

2.08 Tue Nov  1 10:55:00 2011
	 - Wind back pre-reqs for various modules to match what was shipped with Perl V 5.8.1.
	   Many thanx to Brian Cassidy for the error report: https://rt.cpan.org/Ticket/Display.html?id=72068.

2.07 Sun Oct 30 16:08:00 2011
	 - Rewrite Build.PL and Makefile.PL to try loading File::Which rather than assuming it is installed.
	   This avoids the chicken-and-egg problem whereby these 2 programs need File::Which::which to find 'dot'.
	   Many thanx to Richard Clamp for the error report: https://rt.cpan.org/Public/Bug/Display.html?id=71971.

2.06 Tue Oct 25 08:09:00 2011
	 - Add File::Which to the pre-reqs in Build.PL and Makefile.PL.

2.05 Thu Oct 20 10:52:00 2011
	 - Add 'Deprecated. See GraphViz2' to the docs.
	 - Add Build.PL.
	 - Add ability to set ORIENTATION. Thanx to Christian Lackas for the patch. See RT#71787.
	 - Add Changelog.ini.
	 - Add META.json, MYMETA.json and MYMETA.yml.
	 - Add MANIFEST.SKIP.
	 - Ensure all modules contain a version number.
	 - Update the docs regarding the list of modules shipped in this distro.
	 - Remove examples/remote.pl because GraphViz::Remote is no longer shipped.
	 - Clean up examples/clusters2.pl.
	 - Clean up Makefile.PL.

2.01 Fri Sep 24 17:02:29 GMT 2004

        - thanks to Ron Savage, patched to work under systems
          which have an executable extension, such as Windows

1.9 Tue Aug 24 15:30:31 GMT 2004
	- check for "dot" in the Makefile.PL instead of a test, as
	  suggested by Autrijus Tang

	- this is the Flight 63 edition

1.4 Wed Oct  3 07:57:42 GMT 2001
	- added new filehandle, scalar reference, and code reference
	  scheme to as_* to allow streaming of data, rather than
	  accumulating potentially very large output in memory (based
	  on patch by Dave Rolsky)
	- new pagewidth and pageheight graph attributes for creating
	  PostScript mosaics of large graphs (idea by Nelson Loyola)

1.3 Sun Aug 19 15:43:02 GMT 2001
	- labels can now contain quotes
	- fixed bug: labels can now start with a number

	- new 'rank' node attribute allows nodes to be ranked
          at the same level

	- added a reference to brian d foy's DDJ article on
	  Devel::GraphVizProf
	- put the entire Perl regular expression test suite through
	  GraphViz::Regex and fixed all the bugs
        - no longer sort nodes by default (idea by Stephen Riehm),
          which makes graphs just work better. Not documented, do
          you want it to be?

0.14 Thu May  3 17:57:57 GMT 2001
	- added support for InterpLit node in RecDescent grammars
	- added cumulative effect for node attributes (patch by Diego
	  Zamboni)
	- changed the quoting rules again to make it easier to read
	  the dot files (idea by Diego Zamboni)
	- make add_edge() automatically add any nodes specified for
	  the edge that have not been previously added to stop the
	  Graph module complaining (patch by Diego Zamboni)
	- new 'node', 'edge', and 'graph' graph attributes to specify
	  global node, edge, and graph attributes (patch by Diego
	  Zamboni)
	- removed t/regex.t and documented that GraphViz::Regex may
	  not work on various perls
	- added GraphViz::Regex_YAPE module, another way to graph
	  a regular expression

0.13 Mon Mar 19 19:31:18 GMT 2001
	- removed 'use warnings' as suggested by David Adler so we
          no longer require Perl 5.6
	- moved all modules into a new 'lib' directory (and updated
	  examples) so that Devel::GraphVizProf gets installed
	- new 'concentrate' graph attribute to merge edges in
	  cluttered directed graphs
	- new 'random_start' graph attribute, which requests an
	  initial random placement for the graph
	- new 'epsilon' graph attribute, which decides how long the
	  graph solver tries before finding a graph layout, requested
	  by Pierre-Yves Genot
	- an empty cluster now means not clustered
	- added GraphViz::Regex and example regexp.pl which visualises
	  a regular expression
	- now an award-winning module!

0.12 Tue Mar  6 17:37:21 GMT 2001
	- fixed bug in redcarpet.pl example
	- new rankdir graph attribute, which controls the direction
	  the nodes are linked together (patch by Mark Fowler)

	- added GraphViz::Remote so that you do not need to install
	  the graphviz tools to use this module

	  graphing Parse::RecDescent grammars (idea by Damian Conway)
	- new module XML::GraphViz (and example) for graphing XML
	- new module Data::GraphViz (and example) for graphing data
	  structures
	- new example ppmgraph.pl by Marcel Grunauer which graphs CPAN
	  tarball dependencies using ActiveState's package list (thanks
	  to Brian Ingerson too ;-)
	- new, better, testsuite
	- better quoting (especially in ports) to allow a greater range
	  of characters

	- better quoting of nodes and edges (they can now have
	really wierd names)
	- new examples directory with xref.pl: "graphing subroutine
	cross-reference reports for Perl modules" and example graph to
