Right. I didn't want to push something out with a known-broken function.

I would have rather the patch just remove the function in that case,
(but the fact that someone noticed the broken function meant that
someone actually *was* using it and removing it wouldn't be nice
either).

Done and pushed out now.

That's the approach I took, with naming of
notmuch-show-next-message-without-marking-read. And yes, the naming we
have for our emacs functions is awful. I really dislike "notmuch-show"
as a prefix because it puts a verb in the prefix, (where I'd instead
like to just have a verb for the actual functionality of the function).

But we have to have at least *something* to separate the search-results
and message-viewing modes, (since we have commands like "archive" in
both of them). The lack of nice scoping here is really awkward.

Well, it is fatal in the sense that it makes that function useless. But
it's not as bad as it is currently unused. You will only notice it if you
make the "skip to next unread" (interactive) and bind it to a key (which
is what I have done). I still think it's worth taking this patch and fixing it 
then.

The solutions I can see are: 
- split into a "notmuch-show-next-message"
  and a notmuch-show-show-next-message (what a naming!) function. 
  One would merely skip to the next and one actually show and mark unread.
- Introduce a second argument option whether we should mark as unread or not.
- rework "notmuch-show-next-unread-message" to not make use of
  "notmuch-show-next-message" but e.g. to just use
  "notmuch-show-find-next-message" or so.

Does this make any sense?

Touché. As explained above. I made it interactive and bound it to 'n'.

I certainly don't see it as fatal, but it is something we should
resolve.  I think the simplification that the patch provides is worth
it.

I'm seeing the notmuch-show-next-unread-message as a non-interactive
function that's not currently called by any other functions, and is
therefore not being used.  Sebastian, are you using that in a private
function, or am I misreading the code?

jamie.

Hi Jameson,

Thanks for contributing the patch. This exact feature, (removing all
commands with "and mark read" in their names), has been on my todo list
for too long, and I'm anxious to remove it from that. But...

...that seems like a fatal bug in this script. Thanks for noting that
Sebastian.

I'm very interested in augmenting the test suite such that we could
write emacs-based tests that would capture this bug. It seems that with
the --batch, --load, and --funcall options it shouldn't be too hard to
write a modular function exercising emacs code and then execute it
no-interactively. Then we could either inspect the state of the database
to ensure the operation worked as desired, or else have the test
function write a buffer out to a file and test that the file has the
desired contents.

So that's something I'll be working on soon. And of course, I'll always
be glad to accept any help.

-Carl

Hey, Sebastian.  I'm glad you've been finding the patch useful.  I'd be
happy to look at improving it, or of course accepting patch.  I was
hoping Carl might process these patch first, in which case it would be
easier to know what any improvements might look like.  I'll send a
separate email to ping Carl about that.

jamie.

Hi Jameson,

I've been using this for quite some time now and I am pretty happy with
it. However, there is a problem with this approach as this renders the
function notmuch-show-next-unread-message useless. 

This proceeds to the next message, using
notmuch-show-next-message, which your patch marks automatically as read.

It then checks the unread status in order to decide whether to proceed
to the next again. So with your patch notmuch-show-next-unread-message
will skip through all messages in a thread thinking they are all read
(and actually marking all as read).

Sebastian
