Unfortunately the customize-interface for more customized entries in
notmuch-hello-sections looks a bit weird, but I couldn't figure out how
to get rid of the empty lines produced by generating the lambda expression
needed.

To avoid unnecessary complexity in the code this patch removes
aligning all the tag entries in different sections (e.g. saved
searches and all tags) the same way. So if someone really thinks this
was an important features, please yell loudly.

Cheers,
Daniel

This patch makes the notmuch-hello screen fully customizable
by allowing the user to add and remove arbitrary sections. It
also provides some convenience functions for constructing sections,
e.g. showing the unread message count for each tag.

This is done by specifying a list of functions that will be run
when notmuch-hello is invoked.

This patch makes the notmuch-hello screen fully customizable
by allowing the user to add and remove arbitrary sections. It
also provides some convenience functions for constructing sections,
e.g. showing the unread message count for each tag.

This is done by specifying a list of functions that will be run
when notmuch-hello is invoked.

Hi Daniel,

this looks really great and it comes at the right time for me. I can use
it for creating a custom section "What's in your inbox" - a
functionality which I previously implemented in my personal branch [*]
but I was unable to rebase it on the current HEAD. Basically, it took
all saved searches and tag searches, filtered them with tag:inbox and
displayed the buttons for those searches.

With your patch it is "quite easy" to implement such a functionality.
There are a few problems, though.

First, the customization interface for the custom sections (not the
predefined ones) is very confusing. I was not able to use it at all.
Instead I hacked the source code (see below) to add my section to the
notmuch-hello-sections list.

Second, when I tried to understand your patch, I found some names of
functions and variables quite confusing. In the patch below, I tried to
give them a better names and I also updated the documentation. Feel free
to use my changes for your later patch submission.

And last but not least, you allow quite wild modifications of tag
searches (e.g. in notmuch-hello-generate-tag-alist), but is might be
also useful to use such modifications for other searches. For example, I
want to modify the saved searches in a similar way.

I do not miss this at all.

And here are my changes to your patch, which you might use as a
suggestions for a next version of your patch. As I wrote above, it
renames some functions and variables to more understandable names,
updates documentation and adds a custom section for my personal use (I
can live with this custom section in my .emacs if others do not like
it).

Cheers,
-Michal

What specifically did you find confusing? The first customization-option
is intended for sections like the all tags section which various
configuration options which should be explained by the docstrings next
to the options. The second item allows saved-searches-like sections.

By the way: Instead of editing the source directly, you can also put all
customizations like that in your configuration files and set
notmuch-hello-sections from there. Nevertheless your inbox-display
functions look useful in general so they should indeed be included.

Thanks, those look quite a bit clearer, naming things like that is
really not my strong suit. I'll include them in the next version of the
patch.

Are you referring to things like specifying a filter for each tag or
count in saved-searches? My thinking was that since you specify each
item manually anyway, you can append any filter you might want to use
there. But I guess you're right that it's a bit more convenient to be
able to specify those once and not having to repeat it for each item.

If we add the same configuration options that
notmuch-hello-generate-tag-alist accepts, this section should be easy to
specify in your ~/.emacs with one or two lines anyway.

Cheers,
Daniel

Sorry for not being clear - I wrote the mail late at night, looking
forward to some sleep :)

I'm talking about notmuch-hello-section. It seems it is not possible
easily specify there your own function. You can either select a
predefined section or "Customized section", which is in fact "Customized
all-tags section". So I propose to renaming this entry like this and
adding another one called "Custom function", where you could enter the
name of your function.

I know that, but I wanted to do the experiment quickly and this was the
easiest way for me. Regarding setting of notmuch-hello-sections from
.emacs, I prefer customizing it through the customization interface
because when somebody else introduces a new section it is more
convenient for me to try it by choosing from predefined values than
modifying that in .emacs.

It seems that I still do not understand what the "Customized section"
was intended to provide. I have to say I'm not able to fully decode the
definition of notmuch-hello-customized-section, but it seems to me that
it is a way how to customize a call to notmuch-hello-insert-all-tags.

I wanted to say that it might be useful to have the similar options for
saved searches. For example, what I do in my notmuch-hello-insert-inbox
is to take the saved searches and filter them by tag:inbox. I guess that
if there is a possibility to do that without coding in elisp, some
people may find it useful. What do you think?

Ah, I see why it confused me: You are referring to the first version of
the patch. This particular bit is already clarified in the second
iteration of the patch, starting at
id:"1309613471-23465-1-git-send-email-daniel.schoepe@googlemail.com"

In that case I also fully understand why you found the
customize-interface confusing. :)

Yes, that was the intention, in v2 I used a cleaner way to do that.

Ah okay, then I understood you correctly. I agree that this would make sense.

This patch makes the notmuch-hello screen fully customizable
by allowing the user to add and remove arbitrary sections. It
also provides some convenience functions for constructing sections,
e.g. showing the unread message count for each tag.

This is done by specifying a list of functions that will be run
when notmuch-hello is invoked.

I sent a new version of the patch that incorporates your suggestions
with one exception: I removed notmuch-hello-insert-inbox from the
default value for notmuch-hello-sections, since personally I find it a
bit confusing to have all tags with inbox-tagged messages
mixed with the saved searches in one place.

Hi,

this is definitely better than the first version I was using! Thanks.
See other comments below.

I'm not sure it is a good thing to remove customizations that are
included in a released version. Some users may configure it and their
configuration disappear when they install a new version. Is there a way
to migrate this settings to a new, section-based one?

This is IMHO still hard to understand only from looking at the
customization widget. Ideally, I'd like to see somewhere a paragraph
like this: "This displays a list of all tags, optionally hiding some of
them. It is also possible to filter the list of messages matching each
tag by an additional filter query. Similarly, the count of messages
displayed next to the buttons can be generated by applying another
filter to the tag query."

Actually, when reading the above paragraph, it still seems a way too
complex. What about the following: I do not think it has sense to list
custom tags with zero counts - I think everybody would use
:hide-empty-tags all the time. Then, the result of listing all tags with
'notmuch search-tags', filtering them with 'filter' and throwing away
empty tags, would be the same as running 'notmuch search-tags filter'
and then finding the counts by 'notmuch count tag:TAG and filter'. One
of the advantage of this approach is that it would probably be faster to
generate the section, because you won't query the counts of all tags if
your filter matches only a few of them.

Additionally, as I didn't read carefully your previous discussions about
the additional filter for counts, I do not see much use for it. If you
only want to see which tags has unread messages, you can simply add a
new section with (:make-query "tag:unread") and you would get what you
want. You can also disable all-tags sections.

So my proposal is to forget about different queries for filters and
counts and having here only the following options: filter, hide-tags and
hide-if-empty.

Then, the documentation would be simple: "This section displays buttons
for all tags of messages matching a FILTER. Optionally, some of these
tags may be hidden."

Is there a use case, which is not covered by this?

I can imagine, that :hide-tags could also be a (list of) regexp(es).

This is IMHO not needed here, as you always has to enable this section
manually.

Not needed (see above).

Rename to :hide-empty-queries.

What is notmuch-hello-target? I guess I know what it is from reading the
code, but if I didn't read the code, this mentioning it here would be of
little value for me. Perhaps make the notmuch-hello-target clickable and
document it below.

Add the documentation as discussed above. Additionally, it seems that
having only the label in this variable is not enough, since the same
label can appear in multiple sections. Perhaps, we need both the title
of the section and the label here.

Perhaps you want to end this (and also all other) section with an empty
line so that the order of sections doesn't matter. I use sections in
this order: header, inbox, saved-searches and there is no space between
header and inbox and two spaces between inbox and saved-searches.

I might be useful to include here a link to the customization of this
page. Maybe, it would be useful to have notmuch-hello subgroup in
customization interface and link to this group. But creation of the
subgroup should be definitely in a separate patch.

Thanks again for such a great functionality.

Agreed, I think I only removed it because at the time I first
implemented user-defined sections, my patch, which introduced
notmuch-hello-tag-list-make-query, hadn't been applied yet.

I'm not sure, I can imagine someone wanting to have an overview of all
his tags, whether there are, e.g., unread messages or not. If we decide
to keep this functionality, it should be inverted though, i.e. one has
to explicitly specify :show-empty-searches to get them.

About the counts: I introduced this because Austin Clements says he
finds it useful in his comment here:

id:"BANLkTi=729DWai4q57iBSfz1wDhBXsmndQ@mail.gmail.com"

Also, I think/hope that we can just improve the documentation
sufficiently without sacrificing flexibility.

A user might still want to have the section collapsed when starting the
notmuch UI and only have it shown when he needs it. (I use that for a
section that displays unread counts for each tag).

What do you mean by label? "Custom function"? If yes, that element will
have the actual function name in the input element next to it anyway.

My thinking was to have no section end with a newline and insert a
newline between each section when building the notmuch-hello buffer, to
prevent forgotten trailing newlines when defining a new section.

Yes definitely. Pieter Praet recently sent a patch reorganizing the
customization options into subgroups, so I'll change it once that patch
has been applied.

This wouldn't work for me. My all-tags section covers almost entire
screen and finding non-zero entries there is not very convenient. I find
much more useful to have a section saying: "Hey, you have unread
messages only for these three tags". Moreover, it wouldn't help me to see
non-zero number of unread messages and when I click the button I would
see all the messages, not only the unread ones. It simply seems very
confusing to me.

I agree that it is useful to see unread counts, but it is not useful to
see all messages when I click the button.

You are right. I use emacs --daemon so I actually initialize notmuch UI
only when emacs crashes or when I run out of battery power ;-)

If I understand this variable correctly, it stores the label (text) of
the button you have your point at. This allows you to stay at the same
button after reloading of notmuch-hello even if the layout changes,
right? Then having the same named button in multiple sections results in
moving the first (or last) occurrence of this button when notmuch-hello
is reloaded.

I agree with you, personally, but I don't think this particular bit
(:hide-empty-searches) increases code complexity that much (and all of
it is localized to the functions generating the sections, which possibly
should be moved to a separate file). I also find it plausible that a
user might want behavior like this (as, e.g. an overview, if he doesn't
want an all tags section, but still see what tags he has set).

Hence I don't see why we should not provide this option.

As I said, this is not my preference either, but personal taste is not
necessarily the best argument for _not including_ something, especially
for the UI of a mail client. And in this case there even is someone
saying that behavior would be useful to him.

Yes, me too, but I like seeing only sections that I care about every
time I open notmuch while still having more information available in a
convenient way. But I'm not too attached to this feature, so if the
consensus is that that bit should be removed, I'll bow to public opinion. :)

Ah, I misunderstood what you were referring to earlier. That was already
case before my patch though, except that now it's more likely to have
buttons with the same name. Anyway, I think this is just a minor issue
and can be addressed in a different patch.

In any event, this definitely needs better documentation.

Thanks for all your input on this!

Cheers,
Daniel

OK. I changed my mind. I thought that the approach with 'notmuch
search-tags QEURY' followed by 'notmuch count tag:XXX and QUERY' for
returned tags would be faster then 'notmuch search-tags' followed by
'notmuch count tag:XXX and QUERY' for all tags, but it turned out not to
be the case.

I played with the customization interface a bit and found the following
problems:

- It is annoying to insert section titles that includes ": " at the end
  in order to be nicely "rendered". I think this could be appended
  automatically.

- :hide-empty-tags should be renamed in :hide-empty-searches to be
  effective (see the patch below).

- The title of custom tags section was not passed correctly to the
  functions. This is also fixed in the patch below.

For me, the stronger argument was that the code would have been simpler,
because notmuch-hello refreshes don't happen that often that performance
shouldn't matter much.

Agreed.

This has been done in v4 of the patch, for which I screwed up the
In-Reply-To header and hence is listed as a separate thread:

id:"1310079227-19120-1-git-send-email-daniel.schoepe@googlemail.com"

I changed title to a mandatory argument for consistency with
notmuch-insert-searches and because a title-less section wouldn't make
much sense anyway.

Cheers,
Daniel
