Re: Fwd: Support compilation of Haskell in org mode babel blocks.
Sorry, I was working on the emacs git repo, which seems to be a bit behind
the org mode one.
Please find patch attached.

Re: Fwd: Support compilation of Haskell in org mode babel blocks.
I added version 9.4 to ORG-NEWS.
Please tell me if that's OK or I should instead put it in 9.3.

Re: Fwd: Support compilation of Haskell in org mode babel blocks.
I am confused about the last point: Use a let-binding instead of setq. If I use: (let* compile (string= (cdr (assq :compile params)) "yes")) I get the following error: ob-haskell.el:158:1: Error: Wrong type argument: listp, compile If I leave with set: (setq compile (string= (cdr (assq :compile params)) "yes")) I get the following warnings: ob-haskell.el:161:12: Warning: assignment to free variable ‘compile’ ob-haskell.el:161:12: Warning: reference to free variable ‘compile’ Upon searching the web, I find a relevant this relevant post <https://emacs.stackexchange.com/questions/21245/dealing-with-warning-assignment-to-free-variable-when-certain-libraries-can-b>, whose conclusion (if I understand it correctly) is that we could live with those warning raised by setq. Apart from this issue I am ready to submit a fixed patch. What do you recommend?

Re: Babel Haskell. Print all results when header has :results output
No, I haven't yet. As it is required to firm them for the other patch, I am willing to firm them but unsure how to proceed. Please advise.

Re: Fwd: Support compilation of Haskell in org mode babel blocks.
I have read the page about signing FSF papers, but I am unclear about how to proceed. Could you give some pointers? Thank you.

Babel Haskell. Print all results when header has :results output
Right now, when executing the following source block #+begin_src haskell :results output [1..10] "hello" == "hello" #+end_src I get the following output: #+RESULTS: : True Whereas (for me) the desired result would be #+RESULTS: : [1,2,3,4,5,6,7,8,9,10] : True I created the attached patch that achieves the desired result. Please notice that the default behaviour (without :results output) remains unchanged.

Subject: Support compilation of Haskell in org mode babel blocks.
To:
Haskell code can be both compiled (for example with ghc), or interpreted
(with ghci).
Until now, org babel had only support for interpretation.
Haskell is weird in that some code for the interpreter cannot be compiled
and viceversa.
For example, in ghci (the interpreter) you are required to use let to
declare functions
<https://stackoverflow.com/questions/28927716/org-babel-for-haskell-not-works-of-eval-haskell-block/40920873>
.
In this patch I add support for compilation with the header argument
:compile yes.
The function to compile haskell is almost a copy paste of the C funcion in
ob-C.el.
By default I retain the original behavior, i.e. interpreting the block.
I have tested this patch in emacs-27.0.91.
It is my first patch to GNU Emacs and I am a newbie with both elisp and
haskell.

I learn that — is the hexadecimal code for a dash (-).
As a result of the previously described behaviour, my blog doesn't
display the html. Like a all.
