Hi
First of all thanks for integrating Org-babel into Org-mode.
But for the less fluent elisp and org-mode users, I am slightly confused in
the changes necessary on my side.
I have the following in my emacs.org file:
#+begin_src emacs-lisp
(require 'org-babel-R) ;; requires R and ess-mode
;; (require 'org-babel-ruby) ;; requires ruby, irb, ruby-mode, and
inf-ruby
(require 'org-babel-python) ;; requires python, and python-mode
;; (require 'org-babel-clojure) ;; requires clojure, clojure-mode,
swank-clojure and slime
#+end_src
*** Start babel
#+begin_src emacs-lisp
(org-babel-load-library-of-babel)
#+end_src
*** Customization of sh
set shebang for sh script to "#!/bin/bash" and exclude additional comments
(t)
#+begin_src emacs-lisp
(setq org-babel-tangle-langs
(cons
'("sh" "sh" "#!/bin/bash" t)
(remove-if (lambda (el) (string= (car el) "sh")) org-babel-tangle-langs)))
#+end_src
*** Customization of R
set shebang for R script to "" and exclude additional comments (t)
#+begin_src emacs-lisp
(setq org-babel-tangle-langs
(cons
'("R" "R")
(remove-if (lambda (el) (string= (car el) "R")) org-babel-tangle-langs)))
#+end_src
which custimizes the shebang creation and the comments in the tangled file.
Do I have to change any settings, and if yes, how? The previous conversation
seems to say "yes, it needs to be changed", but I don't understand what and
how.
Thanks,
Rainer.
