> Hi all, > > I'm pleased to announce version 0.2.1 of the diagrams library, > available now on Hackage [1]. This is a minor release which fixes a > few bugs and adds a few new combinators, most notably a grid layout > combinator contributed by Ganesh Sittampalam. For a full list of the > features new to 0.2.1, see the CHANGES file [2]. > > The real reason for the release is to get existing new features out > the door before gearing up for a planned major rewrite of the backend > to use a constraint-solving layout engine. This will allow for much > greater elegance and flexibility, as well as a number of features > (such as arrows connecting different parts of the diagram) which would > be difficult or impossible to implement in the current framework. > > My ultimate vision is for the diagrams library to become a viable > alternative to declarative drawing systems such as MetaPost [3] and > Asymptote [4], with the distinct advantages that it will be > > (1) *purely* declarative, and > > (2) an *embedded* DSL, providing the full power of Haskell and its > ecosystem, as opposed to the ad-hoc specialized languages used > by MetaPost and Asymptote. > > If this sounds exciting to you, I hope you'll join me, either by > trying out diagrams for your projects and providing feedback, or by > contributing some code. If you're interested in helping with the > rewrite itself, let me know; I also plan to set up a core/contrib > model like that of xmonad, so there should also be plenty of > opportunities for contributing independent add-on modules which > enhance the core functionality. > > -Brent > > [1] http://hackage.haskell.org/package/diagrams > [2] http://code.haskell.org/diagrams/CHANGES > [3] http://www.tug.org/metapost.html > [4] http://asymptote.sourceforge.net/ > _______________________________________________ > Haskell-Cafe mailing list > [email protected] > http://www.haskell.org/mailman/listinfo/haskell-cafe >
