Preserve tabs in tangled babel output

Preserve tabs in tangled babel output

[Roger Mason]

Hello,

This code:

#+BEGIN_SRC makefile :tangle Makefile
  hello:  hello.f90
          gfortran hello.f90

  execute: hello
          ./a.out

  clean:
          rm -f a.out *.o
#+END_SRC

(stolen from John Kitchin) produces a Makefile with spaces instead of
tabs.  I created the content in makefile mode, with tabs, but emacs
untabifies the output.  How can I prevent this?

Thanks,
Roger

Use the `-i' results switch:

  #+BEGIN_SRC makefile -i :tangle Makefile

or set `org-src-preserve-indentation' non-nil.

HTH,

I have org-src-preserve-indentation set to t.

Are you saying this does not work on your setup?

When I copy/paste Roger's source block into a buffer, issue
`(setq-local org-src-preserve-indentation t)' in the buffer, put tabs 
before the indented lines (there were only spaces in the gnus 
*Article..* buffer), and tangle, the tabs are seen in the output file.

The -i switch did not work for me but setting
org-src-preserve-indentation did.

Thanks again,
Roger

No I meant to confirm that it does work for me with that setting.
