Hi Bruno,

glad to hear that it works for you.


Ad 'org-babel-script-escape': I use Org version 9.6. I do not temper
with 'org-babel-script-escape', it is used by the respective babel
modules --- 'ob-haskell' in this case. The error also occurs with
'cabal-repl' as process type.


Ad 'haskell-process-type': When I use 'haskell-process-type' 'auto', it
chooses 'cabal-repl' which will also fire up 'ghci' but the setup is
faulty, because it does not find any modules, as I described. I just
checked and this is not a fault of org-mode. The command 'cabal repl'
also fails to access any modules when executed in the terminal. I think
it requires a `.cabal` file, which I usually do not have when using an
Org file. I quote the help text from 'cabal repl':

    Open an interactive session for a component within the project.

I think this is not the correct default for Org mode, because usually
there is no "project", but just an Org file.

If I use 'haskell-process-type' 'ghci', all modules I have installed
along with GHC are found, as I expect them to be.


Ad scrambling: The scrambling happens with multi-line input. For example

    #+begin_src haskell :exports both :results output
    let x = 10
    let y = 12
    x*y
    [x,y]
    #+end_src

    #+results:
    :
    : ghci> 120
    : [10,12]

Do you get syntax highlighting when the source code is indented (for
example in list items).

Thanks for your reply!

Dominik
