I'm pleased to announce that I've finally tracked down all the pesky
little bugs that prevented me from releasing version 2999.16.0.0 of my
graphviz library, that helps you use the Graphviz suite of tools to
visualise graphs.
The important changes are:
* Add support for Graphviz-2.30.0:
- New attributes:
+ `Area`
+ `Head_LP`
+ `LayerListSep`
+ `LayerSelect`
+ `Tail_LP`
+ `XLP`
- `BgColor`, `Color` and `FillColor` now take a list of colors
with optional weightings.
- Layer handling now supports layer sub-ranges.
- Added the voronoi-based option to `Overlap`.
- Added the `Striped` and `Wedged` styles.
* Updates to attributes and their values:
- The following attributes have had their values changed to better
reflect what they represent:
+ `FontPath` takes a `Path` value.
+ `Layout` takes a `GraphvizCommand` (and thus
`GraphvizCommand` has been moved to
`Data.GraphViz.Attributes.Complete`).
- Added `MDS` to `Model` (which had somehow been overlooked).
- Various attributes now have defaults added/updated/removed if
wrong.
- Removed the following deprecated attributes:
+ `ShapeFile`
+ `Z`
* Now any value that has a defined default can be parsed when the Dot
code just has `attribute=""` (which `dot -Tcanon` is fond of doing
to "reset" attributes).
* `GraphvizCommand` now defines `Sfdp` (which had somehow been
overlooked up till now).
* The `canonicalise` and related functions have been re-written;
whilst there might be some cases where their behaviour does not
fully match how `dot -Tcanon` and `tred` behave (due to the
interaction of various attributes), the new implementation is much
more sane.
* Use temporary files rather than pipes when running dot, etc.
Makes it more portable, and also avoids issues where dot, etc. use
100% CPU when a graph is passed in via stdin.
