We already set the permission of tangled files to be executable when
they include a shebang line. Perhaps we could add an option (or change
the default) to set the permissions of tangled files to be read only.
Perhaps this could be done using the post-tangle hook with something
like the following.
;; -*- emacs-lisp -*-
(defun org-babel-mark-tangled-as-read-only ()
"Mark the current file read only.
If it is executable keep it executable."
(if (= #o755 (file-modes (buffer-file-name)))
(set-file-modes (buffer-file-name) #o555)
(set-file-modes (buffer-file-name) #o444)))
(add-hook 'org-babel-post-tangle-hook
'org-babel-mark-tangled-as-read-only)

I did, and there is a problem with tangling multiple blocks into a
single file:
The following does not work:
,
| #+PROPERTY: tangle-mode (identity #o444)
| #+PROPERTY: tangle ./tools.R
| * Two blocks
| Block 1
| #+begin_src R
| suitName <- function(species)
| {
| return( paste(species$layer, "suitability", sep="_") )
| }
| #+end_src
|
| Block 2
| #+begin_src R
| statDistName <- function(species){
| return( paste(species$layer, "disturbances_static", sep="_") )
| }
| #+end_src
`
It seems that the second block can not be written, as the file is
already set to read-only.
For the moment, I exclude this setting again but will try it out as son
as it is fixed.
Cheers,
Rainer
