Special symbols with monospace

Special symbols with monospace

[Jarmo Hurri]

Greetings.

I like to embed pseudocode etc. in example blocks so that it is typeset
in monospace when exported. But sometimes I would need special symbols,
such as \neq, in pseudocode. What is the easiest way to combine
monospace and special symbols?

Is there any problem with UTF-8 symbols such as "≠"? I have typed it using
Compose / =

I resort to LaTeX for this, using a LaTeX src block with the algorithm
and algpseudocode packages.

Would https://github.com/jsalzbergedu/pseudocode-mode be any good?

I will have to explore it. The documentation is almost as thin as my
wallet.

Thanks,

In my case there is a specific pseudocode format I need to use. I think
I would have to try to tune one of these packages pretty heavily.

But I will see. Thanks.

At least out of the box, the UTF-8 symbol is not exported.

All the best,

In that case, you may simply wish to use the alltt environment.  This
works for me:

#+begin_src org
  ,* algorithm pseudo code
  ,#+latex_header: \usepackage{alltt}
  ,#+begin_alltt
  for i \in [0,1] do
    if i \neq 3
      x ← i^2
    end if
  end for
  ,#+end_alltt
#+end_src

HTH,
eric

#+BEGIN_SRC emacs-lisp
(add-to-list 'org-latex-inputenc-alist '("utf8" . "utf8x"))
#+END_SR

Excellent, works for me too.

What a great community!

Is there any reason why you don't use LaTeX's \leftarrow in place of ← ?
With perhaps a (set-input-method 'TeX).

Funnily enough, it's because I was originally using the TeX input method
(which I love) that I ended up with ← instead of \gets... :-)

I had realized that my LaTeX did not understand ∈ when I exported to PDF
and so I changed all (but not all) input to LaTeX and not utf-8
symbols. I missed that line!
