A few things I forgot to mention in my haste to get this out: 1) I was planning on having a tutorial-style blog post where I'd use graphviz to parse an manipulate the output "ghc-pkg dot"; however I've been busier than I expected recently and figured it'd be better to get this release out and do this later.
2) The website was developed with the help of John MacFarlane; at the moment I'm using the CSS he uses for Pandoc's homepage, but I plan on updating that during the week (again, better to get it out now and fix it later). And with that, I need to sleep. Having a public holiday to get this finished in was nice, but it didn't help with my sleep deprivation :s On 26 April 2010 23:46, Ivan Lazar Miljenovic <ivan.miljeno...@gmail.com> wrote: > > I'm pleased to announce the latest version of my graphviz library that > provides Haskell bindings to the Graphviz graph visualisation suite. > > There are numerous changes in this release, the most important of which > are: > > * graphviz now has an FAQ and an improved README as well as its own > homepage: http://projects.haskell.org/graphviz/ (as prompted by Eric > Kow). > > * Add support for record labels; values are automatically > escaped/unescaped.
