Hi Sébastien,
The temp -> rename approach is good, but you should probably use
make-temp-file to create the file to reduce the risk of
collisions/race conditions. For example as (make-temp-file (concat
file-name ".tangling")).
I think that the location of condition-case is ok, but I wonder what
would happen if something were to fail before entering that? I think
that only a subset of the files would be tangled, but they would all
have their correct modes, so I think that that is ok.
I also think that the message to the user should probably not be
changed right now. While it might can be useful for debug, if someone
is tangling to a large number of files then the filenames/paths are
going to flood messages, so I would leave it out of this patch, and
possibly submit it as another patch for a separate discussion.
Best!
Tom
