I'm sorry for being silly, but what's the motivation of having this canonic form? =)

A few things come to mind:

* Easier to reason about, [...] * Less ambiguity: [...]

So you want to do some post-processing to the Dot graph inside Haskell-land? Or is it just a pretty printer? I mean, Dot will accept both and produce the same result (by definition), so if you just wanted to draw it then there wouldn't be any difference.

It's not just to draw it, it's for when you import some Dot code and then want to edit it (add some extra attributes, etc.). And to an extent, it's also a pretty-printer (though graphviz's pretty-printer will still probably stick to using "dot -Tcanon" as it's using the pretty library, which doesn't support infinite-length lines with indenting). -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
