Whenever I try and evaluate the Haskell code block I get:
"Code block returned no value."
#+begin_src haskell :results value
let fac n = product [1..n]
[(x,fac x) | x <- [0..11]]
#+end_src
#+results:
I am using ghci as my haskell-program
The Haskell source is correctly executed in the *haskell* inferior mode.

I can't reproduce this problem. With a minimal emacs config started
with -Q, and loading the attached init.el file (you'll have to update
the paths to work with your system).

I'm able to execute the following Org-mode file returning a table of

Well that's really odd: I modded the paths in init.el and did the following:
emacs -Q -l init.el foo.org
When I eval'ed the code block in foo.org (twice) I still get message: "Code block returned no value"
I've attached the inferior haskell buffer and all relevant files.

the raw value from:

I might be worth noting I am running on OS X not Linux but the raw data looks reasonable to me…

I thought maybe it could be a difference between our haskell modes, so I
switched to the latest available through my elpa (haskell-mode-13.6),
and I still see the correct behavior.

My *haskell* buffer looks different then yours. Namely I have
"Prelude>" where as you just have ">". I don't know if this is
significant. Maybe you've customized your ghci prompts in such a way
that the comint functions can no longer recognize where output begins?

I'm not sure what else this could be. One option would be to instrument
`org-babel-execute:haskell' or `org-babel-comint-with-output' with
edebug, and then step through evaluation to see if you can pinpoint
where the problem lies.
Hope this helps,

Hi Eric,
Thanks for investigating this.
You got it! The blooming prompt! As you say the comint parser expects "Prelude>" and I have customised my prompt in .ghci (also this wouldn't work with module loads like :m +Mymodule.Foo as this changes the ghci prompt).
BTW if I use a unicode sequence for the prompt (like a greek lambda as a few knights of the lambda calculus do) then accept-process-output hangs!
Well at least that's me fixed! Would it be possible for comint to learn the prompt by sending an empty line and then adapting? -- It would need to do this every time it sees a :command and at startup. Of course this is ghci specific.
Or is the answer to write an evaluation server for ghc with a well defined client API? Then Haskell integration gets a lot easier -- this would be like slime (common-lisp) for Haskell. Might be worth an enquiry on the Haskell list as there is a Haskell API that might cover the requirement.

I would take this up either with the maintainers of comint-mode, or
possibly the inferior-haskell developers. The function used by Org-mode
(namely `org-babel-comint-with-output') uses standard comint variables
(e.g., `comint-prompt-regexp'), so this is one area where the Babel ship
rises and falls with the quality of the Emacs tide.

I would imagine that ghci on the haskell side should be fairly easily
adjusted to support such a use case. Maybe just passing an option when
ghci is started to inhibit any prompt customization would be
sufficient. Another option from the Org/Babel perspective, would be to
add support for non-session evaluation, i.e., compiling the code block
to an executable (perhaps with some default main function), and then
running that executable, as we currently do with C.
