Yes, this is exactly what I wanted! Thanks, and thanks for writing
it all in the first place. :-)
However, I haven't quite been able to get it to work fully. I did
get it installed and running, after I took the advice about using
the latest versions and just installing the binaries. I even got
pfe to add all my files and all the relevant ghc-6.4.2 libraries
and Prelude. However, pfe chase only worked on my files, and
not on, say, /usr/local/src/ghc-6.4.2/libraries/base/parsec. I
had to add all the ghc files one at a time. Also, now that pfe
is satisfied that it needs no more modules, if I run pfe deps,
for example, it complains that I have many undefined export
entries. All of the functions listed are Prelude functions.
I have the prelude option set to True. It seems like I'm very
close. What am I doing wrong?
Here's the output of pfe options, fwiw:
Flags {prel = True, plogic = True, cpp = Just /lib/cpp -traditional -P
-D__HASKELL98__ -D__PFE__
-I/usr/local/src/ghc-6.4.2/libraries/base/include}
Thanks again.

Hi,
The pfe command line tool from the Programatica Project has functionality that
seems to fit fairly well with what you are asking for:
pfe deps -- lists function level dependencies
pfe needed -- lists everything needed by a definition
pfe dead -- lists unused definitions
pfe slice -- extract a slice by eliminating unused defintions
For more information, and downloads, see

Hello. This seems like a basic question, but I haven't
been able to find an answer. I have a pile of Haskell
code that is compiled into a library, and a Haskell program
that uses this library. What I would like is something
that will look at my program and follow the function calls
until it gets to the Prelude. I want to know which functions
in the library and in the Prelude actually get used (at
least potentially).
