newbie questions

[Tamas Papp]

Hi,

I just started using notmuch.  It is fascinating, but I still need to
figure out a few things:

1. How can I restrict searches (eg of my inbox) to the last few
messages (eg 50-100) or some date (eg last 2 weeks)?  I am using the
Emacs interface.

2. Could someone point me to some guides on workflow with notmuch in
Emacs?  So far I have been using mutt, and I guess I need to rethink a
few things.

3. If I have multiple accounts, how can I change my e-mail address
(From:) when I am writing messages (within emacs, using the m key).

Thanks,

Tamas

Well, the query syntax is <start unix timestamp>..<end unix timestamp>. I
know there's been talk on the list about some way to use it more easily
in the queries, and it wouldn't be hard to write a function that
generated a query using a more human-friendly notation of time. So far I
don't know about anyone actually having written such a function though,
but I wouldn't be surprised if someone has.

Possibly. I've only used mutt briefly and a very long time ago, so I
don't really remember, but as you've probably already seen notmuch
relies very heavily on tags, as opposed to just about any other email
client out there (except Gmail, which I've found to be very similar). So
»inbox«, »archived«, »read« and so on isn't really »boxes« the way one
is used to, rather than separate labels you can set (and unset) on each
thread.

My workflow is something like this: first I fetch mail from IMAP using
offlineimap, then I run a script that tags incoming mail as personal,
list, notmuch, rss and so on (notmuch is also my RSS reader). I've set
the saved searches in Emacs to show fairly standard »tag:<tag title> AND
tag:inbox« searches for most of my tags. Then each morning, I begin by
processing »personal« from the top to the bottom, because the »personal«
tag is the one most likely to contain important and/or time-critical
mail (in effect it is the catch-all tag for all mail that isn't directed
to a mailing list or otherwise filtered out as probably uninteresting).

If you're interested, I can send you my mail tagging script.

When I'm done with each mail I archive it (using the standard keybinding
»a«). Most mails are handled more or less immediately, but some (in
particular posts from RSS) take longer time to read. Those I tag with
»read/review« using a custom keybinding »T«. I can then process those
when I have the time.

I'm mostly changing this by just typing my other email address (and
tab-completing it of course). I actually haven't thought about there
being any other way, but now that you mention it there probably is. :)

Hope this helps! Albin

Currently, if you have GNU date you can run from command line:

date +%s.. --date '2 weeks ago'

Then paste the string 1327300096.. to the search field.

guides??? what guides??? ;) http://notmuchmail.org/ has some (old)
practices available...

This is something I've long been planning to look out but so far
my needs have been so small that the effort threshold has not been
passed...

FWIW, I actually have a hacky date parser baked into my
remote-usage-and-other-stuff script (a more idiosyncratc python
version of the bash script on the wiki). I found that I needed
date-searching pretty frequently, since language and senders seem to be
repeated pretty often in my world. It just parses a "date:" term, passes
it to GNU date, and proceeds with a term in notmuch language. It also
does some day-rounding, since by "date:'2 days ago'..yesterday", I mean
"beginning of day before yesterday to end of yesterday," not "48 hours
ago until 24 hours ago."

I'm not swearing by its efficiency, or even its correctness, but it has
made my life easier. The basics are as follows:

    DATE_PATTERN = re.compile(r'^date:([^.]+)(\.\.)?([^.]+)?')
   
    def replace_date_args(st):
        out = subprocess.check_output([GNU_DATE, "+%s", "-d", st])
        return out.strip()
   
    def round_day_down(timestamp):
        tup = datetime.fromtimestamp(int(timestamp)).date().timetuple()
        return time.mktime(tup)
   
    def round_day_up(timestamp):
        date = datetime.fromtimestamp(int(timestamp)).date()
        date += timedelta(days=1)
        tup = date.timetuple()
        return time.mktime(tup)
   
    def parse_date_args(st):
        re_match = DATE_PATTERN.match(st)
        if re_match:
            grps = re_match.groups()
            start_term = grps[0]
            if not (grps[1] or grps[2]):
                stop_term = start_term
            elif not grps[2]:
                stop_term = "now"
            else:
                stop_term = grps[2]
   
            try:
                start = round_day_down(replace_date_args(start_term))
                stop = round_day_up(replace_date_args(stop_term))
                return "%d..%d" % (start, stop)
            except OSError:
                return st
        else:
            return st

And then in the main routine, I have a parse-and-replace step:

    args = sys.argv[1:]
    try:
        if args[-1] == ")'":
            args = args[:-2] + shlex.split(sys.argv[-2]) + [")'"]
        else:
            args = args[:-1] + shlex.split(sys.argv[-1])
    except IndexError, ValueError:
        pass

    args = [parse_date_args(a) for a in args]

I'm only giving the relevant parts here, of course.

Best,
Jesse
