Trouble passing variables into shell blocks on windows

Trouble passing variables into shell blocks on windows

I'm having difficulties passing org variables into shell source blocks.
This is using Windows 7 and Cygwin with bash shell. For instance, the
following

#+BEGIN_SRC sh :var x="."
  ls $x
#+END_SRC

fails with the error message (as displayed in emacs)

  ls: cannot access .^M^M : No such file or directory


As far as I can see, the first ^M stems from org-babel-sh-var-quote-fmt,
and the second from org-babel-expand-body:generic, but I haven't been able
to figure out a solution. Any suggestions?

I can reproduce this using the native Windows build of emacs. If you are
using cygwin tools, consider using a cygwin build of emacs, which will
not suffer from this problem.

If you running an X server then the cygwin emacs-X11 package is what you
need. If you don't want to run an X server then the emacs-w32 package
may fit your needs (a cygwin native build of emacs that uses the Windows
GUI for display).

HTH,

Thank you for the information -- I suppose the cygwin version of emacs may
be the only viable option. Still that seems like quite a big change,
swapping emacs versions, just for this particular feature.

I dunno what's the real impact of that, but pay attention that the "sh"
language has been renamed "shell" quite a long time ago (more than one
year IIRC).

Best regards,
