Thanks Ihor. I don't actually use Haskell. Earlier this year I
attempted to complete the Org Babel language documents on Worg,
but couldn't get the obligatory "hello world" code block to behave
in Haskell. I'm guessing that ob-haskell.el actually works for
experienced Haskell programmers and was hoping someone had a
solution to the Prelude> problem. I'm not sure when I might get
back to this.
All the best,
Tom

I'm struggling to write a minimal ob-doc-haskell.org for Worg.
I installed Haskell via Spacemacs (development branch) and the
Haskell installation appears to be functioning correctly.
The obligatory Hello World! example yields bad results.
#+name: haskell-hello-world
#+begin_src haskell
main :: IO ()
main = putStrLn "Hello, World!"
main
#+end_src
#+RESULTS: haskell-hello-world
: Prelude> Hello, World!
I'm guessing the "Prelude>" part of the output is the prompt
from
the interpreter.
I found this in ob-haskell.el:
(setq-local comint-prompt-regexp
(concat haskell-prompt-regexp
"\\|^λ?>
"))))
But I couldn't find a way to modify haskell-prompt-regexp
without
changing the source.
Advice welcome.
I guess you can report this as a bug in Haskell-mode?
haskell-prompt-regexp is defined there.
If absolutely necessary and if you want that _your_ Haskell
prompt is
different from Haskell-mode defaults, just setq
haskell-prompt-regexp in
your config.
