Specifying the execution function and/or nested major mode for babel blocks

Specifying the execution function and/or nested major mode for babel blocks

[Vladimir Nikishkin]

Hello, everyone.

In org.el we have the following:
(require (intern (concat "ob-" lang)))

This is fine most of the time, however, there are exceptions.
The one I am interested in is fortran/f90. There are separate
fortran-mode and f90-mode, however, afaiu, just a single
ob-fortran.el, which works fine with both of those.

Moreover, when I make block like:
#+begin_src fortran
#+end_src
or turns on syntax highlighting for fortran-mode, not for f90-mode.
I can make blocks like:
#+begin_src f90
#+end_src
This makes syntax highlighting work, but evaluation doesn't, because
org doesn't know that f90 and fortran have the same evaluation
(compilation) function.

I feel that this is a super minor thing that can be solved in, like,
one line of code. But I don't seem to be able to find which one.

Any suggestions?

Vlad

In that case, you'd just need (fortran . t) in org-babel-load-languages,
I think.

Perhaps you're looking for org-src-lang-modes?  This (untested) might do
what you want:

  (add-to-list 'org-src-lang-modes '("f90" . fortran))

Language alignment is fine. What needs to be done is to make org-babel
use org-babel-execute:fortran for both begin_src fortran, and for
begin_src f90.

Yeah, my suggestion doesn't make sense given you said there is a
f90-mode.  Try two:

  (org-babel-make-language-alias "f90" "fortran")

Assuming that works for you and is expected to work generally, it'd be
good to add that to ob-fortran.el.
