Re: [Haskell-cafe] ANNOUNCE: pretty-tree

Which links _aren't_ clickable? If you mean the one to diagrams-contrib, since it isn't imported I can't link to that module directly. One thing I just realised: compared to drawTrees, drawVerticalTree reverses the direction of sub-trees (in that it isn't just equivalent to rotating it clockwise 90 degrees); I'll rectify this when I get to my computer later.

The idea is pretty good, although I suggest you make clickable the Haddock's link to modules, because I had to navigate the source in order to find some application as well as nice tree visualizations :)

For a project I'm working on, I got sick of writing out trees by hand. Data.Tree has a drawTree function, but whilst it's better than nothing, I prefer a more top-down "traditional" approach to drawing trees.

So I wrote a package to do just that: http://hackage.haskell.org/package/pretty-tree

(I didn't think to check whether diagrams had capabilities to do so until after I finished, though in this case I prefer a textual approach anyway.)

I'm more than happy to consider adding other forms of drawing trees (though off-hand I can't think of any), or of course you can send me patches since I'm taking advantage of the nice new shiny hub.darcs.net (thanks Darcs team!).

I was going to put an example here but it only really comes out nicely if you're using a monospaced font, so have a look at the Haddock docs for the module once Hackage builds it (in hindsight, I should probably have come up with better labels before releasing the package... oh well :)
