[Haskell] Haskell Applications - reg

[Ganesh Narayan]

Hi List,

I am planning a study on statistical properties of (static) call graphs for
programs written in different languages; the idea is to compute a handful of
"relevant" graph structural metrics  and see what they have to say about the
software/language.

In this lieu, I am studying following languages - C, C++, Haskell, OCaml and
hopefully Scheme and Java. I picked up a handful of Haskell applications
from Haskell Apps repository [0]  and computed the call graph for them [1].
But am not quite sure if the applications are representative; for one, the
graphs are quantitatively distinct! In addition, this difference appears
consistent across the Haskell applications I tried. Am not sure if its GHC
compiler/runtime effect or Haskell effect though. Should the effects are
artifact of disassembly, likely that OCaml graphs would have exhibited them
too.


Is there any particular application(s) that is quintessentially Haskell'sh
that I could convince myself that my samples are representative?! I am
fledging new to Haskell and would appreciate some pointers in picking up the
"few, but ripe" ones. Hope it's fine.

In case any list member is curious, I have got some preliminary plots hosted
at http://agni.csa.iisc.ernet.in/nganesh/plots ; horizontal dividers
represent language boundaries [top, bottom) and in/out/total stand for
degrees. I have five Haskell applications enlisted: Yarrow, Frown, DrIFT,
HaXml.{Validate/Extract}.

Thanks

[0] http://www.haskell.org/haskellwiki/Applications_and_libraries; I picked
up whatever I could compile. I am yet to get cabal running.
[1] Am presently constructing the call graphs from disassembled application
binaries; resultant graph includes ghc runtime library calls.
