Hi.
I'm trying to apply the approach of litteral devops described in
http://www.howardism.org/Technical/Emacs/literate-devops.html and
noticed the following issue.
I'm trying to use execute shell blocks of the following form ("remote" execution of
commands inside a Vagrant VM via tramp through ssh, using a shell mode session) :
#+BEGIN_SRC sh :dir /symfonyvm:/vagrant :var SYNCEDDIR="/vagrant" :results drawer :session centosvm
ls $SYNCEDDIR
#+END_SRC
This works well when not using a session, but when using the session,
the variable evaluation gets stuck, and when interrupted, I can see the
following inside the "centosvm" shell buffer :
/scp:symfonyvm: #$ SYNCEDDIR=$(cat <<'BABEL_TABLE'
The substitution doesn't seem to happen well over tramp in that case,
somehow.
Typing C-c C-d in the shell session allows me to recover.
I suspect an issue related to tramp + session, incompatible with the
variable initialisation mechanism.
Any clue ?
My setup should be org-mode version : 8.3.4 and normally, ob-sh.el
supposedly stock emacs in Debian testing context...
Thanks in advance.
Best regards,
