Hi,
I'm trying to execute code through babel, for the first time -- I did use it
for small examples of LP, but not yet for enhanced work.
This is my first file:
--8<---------------cut here---------------start------------->8---
* Prerequisites
#+begin_src sh :session ecm
cd ~/Personal
#+end_src
--8<---------------cut here---------------end--------------->8---
If I C-c on the command, Emacs hangs -- just doing nothing (like waiting for
something that never comes).
C-g gives this:
--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---
and I have an empty Shell buffer:
--8<---------------cut here---------------start------------->8---
[Wed Nov 25 15:13:10]
[...@mundaneum] ~>
--8<---------------cut here---------------end--------------->8---
What am I doing wrong? Or have I set something wrong (or missing) in my
.emacs file?
--8<---------------cut here---------------start------------->8---
(require 'org-babel-init)
;; activate a subset of languages
(require 'org-babel-R)
(require 'org-babel-sh)
;; make pre-built helper functions available
(org-babel-load-library-of-babel)
--8<---------------cut here---------------end--------------->8---
Anything interesting in there?
BTW, my next question will be: can we have an SSH session? Or, I guess that
it's the difficult part: is there a way to ask the password and go on with my
commands?
Best regards,
Seb
