Hi
I want to use org-mode to create a submit script for a cluster, and would
need the first lines to be as follow:
#!/bin/bash
#$ -cwd -j y
#$ -t 1-5
#$ -l mem_free=4G
at the moment I get:
#!/usr/bin/env sh
# generated by org-babel-tangle
#
[[file:~/Documents/Projects/BiocontrolAndAlienDynamics/HakeaLandscape/trunc/R/spreadSim.org::*submit%20scripts][block-19]]
#$ -cwd -j y
#$ -t 1-5
#$ -l mem_free=4G
1) Is the first line customizable, or do I have to change org-babel-sh.el to
use #!/bin/bash instead?
2) Can I ommit the second and third line (the comments added by tangle)?
Thanks, and I must say org-mode is getting better and better
Cheers,
Rainer

Hi Rainer,
Yes, I've also wanted control over these things from time to
time. Here's a patch. It introduces two new variables; you would turn
off both behaviours as follows:
(setq org-babel-tangle-include-shebang nil)
(setq org-babel-tangle-include-org-coordinates nil)
If Eric approves, he'll apply the patch to the main org-mode git repo. I
suspect you're using git already, but if not then you probably do want
to use it for org-mode.

Hi Rainer and Dan,
I have comments below, I believe this behavior should be possible
through manipulation of some existing org-babel variables.

The first line is customizable through adjusting the value of the
org-babel-tangle-langs variable as show below.
>>

>
The commenting behavior can also be changed using the
org-babel-tangle-langs variable.
The following non-trivial elisp snippet could be added to your emacs
init to make both of these changes.
--8<---------------cut here---------------start------------->8---
(setq org-babel-tangle-langs
(cons
'("sh" "sh" "#!/bin/bash" t)
(remove-if (lambda (el) (string= (car el) "sh")) org-babel-tangle-langs)))
--8<---------------cut here---------------end--------------->8---
the third element of the '("sh" "sh" "#!/bin/bash" t) list will appear
at the top of your tangled files, and the t at the end of the list
should suppress all org-babel comments.
Perhaps we should change `org-babel-tangle-langs' to an a-list and
declare it behind a defvar to make these sorts of customizations easier
in the future.

Hi Rainer,
I see that my patch in fact answered your question (2) and your other
question from your other email. But as for question (1), yes, see
C-h v org-babel-tangle-langs
The value of this variable for me is
(("makefile")
("C" "c")
("sql" "sql")
("perl" "pl" "#!/usr/bin/env perl")
("sass" "sass")
("dot" "dot")
("asymptote" "asymptote")
("latex" "tex")
("ditaa" "ditaa")
("ruby" "rb" "#!/usr/bin/env ruby")
("python" "py" "#!/usr/bin/env python")
("R" "R" "#!/usr/bin/env Rscript")
("sh" "sh" "#!/usr/bin/env sh")
("emacs-lisp" "el"))
One solution would be to change it so that the entry for sh is
("sh" "sh" "#!/bin/bash")
[Having taken some time off, my elisp is now failing me. What's the
right way to do this? If the cars of this list were symbols then we
could use assq-delete-all but as they're strings we can't. This seems
cumbersome
(setq org-babel-tangle-langs
(cons '("sh" "sh" "#!/bin/bash")
(delete (assoc "sh" org-babel-tangle-langs) org-babel-tangle-langs)))
]
