Fortran is supported in the sense that you can edit a block in Fortran mode. But you cannot execute a Fortran block directly afaik. You have to tangle it, compile it and then run the executable.
For example like this: http://kitchingroup.cheme.cmu.edu/blog/2014/02/04/Literate-programming-example-with-Fortran-and-org-mode/ On May 14, 2015, at 2:20 AM, alain.coch...@unistra.fr wrote: I was starting investigating "Working with source code". I tried with the bloc: #+BEGIN_SRC fortran #+END_SRC The 'fortran' keyword is indeed recognized in the edit buffer, and, as far as I can see, everything works quite well. But I later realized that 'Fortran' is not mentioned in the list of supported languages, section 14.7 of the org info manual [File: org, Node: Languages]. Perhaps because it is still in development? But if I had checked this list before, I wouldn't even have tried it, waiting for better times... Is there an independent way of checking which languages are supported? Thanks -- (As an aside note, I fail to understand why the 'Emacs Calc' language, with identifier 'calc', appears before 'C' in the list. Perhaps because it is difficult to update such a two-column format, and 'calc' is close enough to its true place? But, for me at least, I fell that a single column would actually be less confusing; and anyway, I believe a blank line after the "Language ... Identifier" line would help.)
