[-- Attachment #1: Type: text/plain, Size: 387 bytes --]

In December last year was a change introduced, that a file should not be
removed before
tangling (https://lists.gnu.org/r/emacs-orgmode/2021-05/msg00337.html).
In an older bug report
(https://lists.gnu.org/r/emacs-orgmode/2021-05/msg00337.html)
the decision was to remove the file before writing.
I added a variable to switch between both behaviors.

Any feedback or advice is welcome.

Thanks for the patch, but may you please explain why introducing such
variable is useful?

Sure.

I configure all my .dotfiles in an Org mode file and tangle the
configuration in the right places. The tangled files are all
read-only to prevent accidentally editing of the "right" configuration
file. With the current tangling mechanism, this results in a "Permission
denied" error because the function writes to a read-only file. In a
earlier version this use case was possible because the file was
recreated before writing to it.
There are also other people with the same workflow. See an older post to
the mailing list
(https://lists.gnu.org/r/emacs-orgmode/2021-05/msg00337.html).

Some other have the opposite problem. They do not want the function to
remove the file before tangling because it is a symlink.
See this post on the mailing list
(https://list.orgmode.org/orgmode/CAPHku6O9NfVMAfmE3_ahmpJea_2Qm0mJMFX6qPpT8uiQ94KMZA@mail.gmail.com/)

To achieve both use cases, I think an additional variable could be
useful.

Best Regards
Oli

Thanks for the explanation!

I suggest changing your patch, setting the default value of
`org-babel-tangle-remove-file-before-write' to 'auto.
This will keep the current behaviour but fall back to delete + write new
file when the tangle target is read-only.
That will avoid feature regression.

I changed the path as you proposed.

Thanks, but I think that I was not clear enough explaining what I wanted
you to change.

> -(defcustom org-babel-tangle-uncomment-comments nil

I did not ask to change `org-babel-tangle-uncomment-comments'.
I meant that you allow the new variable you propose
(`org-babel-tangle-remove-file-before-write') to have 3 values:
nil, t, and 'auto.

> +(defcustom org-babel-tangle-remove-file-before-write nil

... with default being 'auto, not nil.

Then, with the default value of 'auto, you only call `delete-file' when
the file is read-only.

It would also help to extend the comment ";; We do not erase...", not
just delete it.

Thanks for the update!
Unfortunately, your patch has unbalanced parenthesis and will not work.
I have modified your patch to make things work and to make it conform to
Elisp code conventions. I also removed spurious change in the existing
variable.

See the attached.

Please, let me know if you want to change anything.
Also, if you can, please test my patch with your use-case.
