I am pleased to announce version 2999.11.0.0 of graphviz [1], my Haskell bindings to the Graphviz suite of graph visualisation tools [2]. [1]: http://hackage.haskell.org/package/graphviz [2]: http://graphviz.org/ This release is mostly backwards-compatible (unless you dealt directly with Point and LayerList values); the changes are: * Improved documentation, including examples of how to use `GraphvizParams` values (since several people indicated that they found them confusing) * Addition of the `Labellable` class (and its method `toLabel`) to make it easier to construct labels. * Backslashes (i.e. the `\` character) are now escaped/unescaped properly (bug spotted by Han Joosten). As part of this: - Dot-specific escapes such as `\N` are now also handled correctly, so the slash does not need to be escaped. - Newline (`'\n'`) characters in labels, etc. are escaped to centred-newlines in Dot code, but not unescaped. * `Point` values can now have the optional third dimension and end in a `!` to indicate that that position should be used (as input to Graphviz). * `LayerList` uses `LayerID` values, and now has a proper `shrink` implementation in the test suite. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
