#+TITLE: Format for tangling files
#+DATE: 2010-11-22
#+BABEL: :comments yes
* Bug report
** Script
#+begin_src sh :tangle doit.sh
#!/bin/bash
# L'élève est là-bas...
ls
date
#+end_src
** Execute it in a Bash shell
The tangled file, when launched from withing a Bash shell, returns errors:
#+begin_src sh
address@hidden:.../Accounting/dev 0$ ./doit.sh
./doit.sh: line 4: $'\r': command not found
./doit.sh: line 5: $'ls\r': command not found
./doit.sh: line 6: $'date\r': command not found
#+end_src
The reason is that the tangled file is saved as UTF-8-dos (being under
Windows). It should be saved in unix format. Is there a way to impose this?
* Answer from Eric
#+begin_example
I think this should be possible using the `org-babel-post-tangle-hook' to
re-save the file with a specified encoding. After looking into this a little
bit it appears that you should be able to add a function to this hook which
will update the `save-buffer-coding-system' variable and then re-save the
buffer.
#+end_example
* Tests
** One
Evaluate this:
#+begin_src emacs-lisp :results silent :tangle no
(add-hook 'org-babel-pre-tangle-hook
(lambda ()
(setq save-buffer-coding-system 'iso-latin-9-unix)))
#+end_src
Instead of setting the variable in *post* hook (and saving the tangled file --
for which I did not know how to procede: what's the argument to give to
save?), I wondered if it shouldn't be easier to set it in the *pre* hook...
Though, the above does not work as I would expect.
** Two
After different trials, I came up with the following which works for me...
Evaluate this:
#+begin_src emacs-lisp :results silent :tangle no
(add-hook 'org-babel-pre-tangle-hook
(lambda ()
(setq coding-system-for-write 'iso-latin-9-unix)))
#+end_src
It's not clear to me what's the exact difference between the 2 variables
(=save-buffer-coding-system= and =coding-system-for-write=). But that works:
#+begin_src sh
address@hidden:.../Accounting/dev 0$ doit.sh
accountlog.csv csv2ledger.sh doit.sh ecm-tangle.txt my-csv2ledger.html
my-csv2ledger.txt
Mon Nov 22 13:30:12 2010
#+end_src
Best regards,
Seb
