Problem with #+BEGIN_SRC shell, and export

Problem with #+BEGIN_SRC shell, and export

[François Pinard]

Hi, Org people.

Let me make this report from memory, now that I'm back home! :-)

In an Org file, a coworker used "#+BEGIN_SRC shell" where he should have
written "#+BEGIN_SRC sh".  While this looks like a benign error to me,
it broke my publishing script, and I did not figure at once what was
happening.  At export time, when Emacs is called in batch, the export
procedure dies.  Emacs says that some process disappeared, and I think I
got that the batch Emacs tries to start "M-x shell" under the scene.

Could the HTML exporter (or all of them) protect itself (themselves)
better?  Or else, maybe, if this is a reasonable to do, could Org tell
us, somehow, whenever a source mode (like "shell", here) is "wrong"?

Perhaps one could add '("shell" . 'sh) to org-src-lang-modes.  That
would protect against this particular error.  Whatever solution is
adopted should be easily discovered and sidestepped in case anyone
actually did want to export code using shell-mode for highlighting.

Best,

In this particular case, I don't think adding 

  '("shell" . 'sh)

to `org-src-lang-modes' will help, as shell-mode is a mode for
shell interactions, not just shell editing.  So the user probably
wanted sh-mode instead.

As for making it easier to discover I don't know, the docstring
seems complete enough to me.

Also using 'foobar.sh' is deprecated in current-day bash scripting, it
should just be 'foobar'. But one thing is always current, the shebang -
#!/bin/bash. That, or whatever scripting language is being used
bash/dash/zsh/whatever, it will always say '#!/bin/WHATEVER' applicable
to its scripting language.
