[Caml-list] graphical notation/representation of functional programs?

[Caml-list] graphical notation/representation of functional programs?

[Oliver Bandel]

Hello,


when using graphical representations like in
"The Craft of Functional Programming", so that
a function is a box with in- and output, then
it's a convenient way of looking at functional
programs.

Is that technique of overview more elaborated
used by other people?

Shouldn't it possible to have a graphical notation
for FP, like a functional aequivalent of the notation,
that is used in the OO-programmers world, where
classes and methods and attributes and so on
are presentated in a graphical manner?

Are there papers on that topic?
Or is functional programming in higher spheres
done comepletely an algebraic form 8lambda calculus)?

Ciao,
   Oliver

I don't know of anything formal, but the dataflow diagrams used in some
structured analysis methods feel pretty functional to me.  See, for
example "Modern Structured Analysis" Edward Yourdon, 1989.

Here are two papers i am aware of (sorry, i don't have the urls at hand  
now, but a search
on the web should give them to you) :

* J.ohn Reekie. "Visual Haskell : a first attempt", TR 94.5, U.  
Sydney,, 1994.

* Joel Kelso. "A Visual representation for functional programs", TR  
CS95-01, CS Dept, Murdoch Univ, 1995.

You can also have a look at Reekie's subsequent work on dataflow signal  
procesing (including his phd thesis)

@phdthesis{ reekie95realtime,
     author = "H. J. Reekie",
     title = "{Realtime Signal Processing: Dataflow, Visual and  
Functional Programming}",
     address = "University of Technology at Sydney, Australia",
     year = "1995",
     url = "citeseer.nj.nec.com/article/reekie95realtime.html" }

or on the work

* of Launchburry on Hawk (www.cse.ori.edu/PacSoft/projects/Hawk)
* at Chalmers on Lava (http://www.math.chalmers.se/~koen/Lava),
* O'Donnell on Hydra (http://www.dcs.gla.ac.uk/~jtod/Hydra/)

The laters all use FP to describe hardware systems.

Finally, you could also have a look at

* Camlflow  
(http://wwwlasmea.univ-bpclermont.fr/Personnel/Jocelyn.Serot/ 
camlflow.html)

a system i developed to describe data-flow graphs as caml programs.

HTH,

Jocelyn
