Jump from notmuch to Gnus for nnml, nnfolder?

Jump from notmuch to Gnus for nnml, nnfolder?

[Julien Cubizolles]

I'm trying to use notmuch with Gnus, Tassilo provided a way to jump from
a notmuch search result to the corresponding group in Gnus in
<87r5rk8cmt.fsf@thinkpad.tsdh.de>. However his setup addresses the case
of articles stored in a Maildir.

At the moment, my Gnus setup is a mess of Maildirs, nnml and nnfolder
backends (for "historical" reasons). I guess Tassilo's method could be
tweaked for all file-based backends like nnml but I'm not sure that
would be the case for nnfolder.

For those of you using notmuch with Gnus, what did you choose? Put all
your messages in a Maildir ?

I have all my email in nnml in ~/Mail, and then I have configured nnir
to use notmuch as the backend for searching, by adding
(nnir-search-engine notmuch) to my nnml-entry in
gnus-secondary-select-methods and in my gnus-message-archive-method.

Notmuch is configured to point to ~/Mail, and to ignore the things I
don't want indexed (drafts;cron;spam...)

I search by pressing G G on an email group inside Gnus.

Seems to work quite well.

Is that all you had to configure ? I only get empty results

--8<---------------cut here---------------start------------->8---
Doing notmuch query roger...
notmuch args: search --format=text --output=files roger
Massaging notmuch output...done
Search produced empty results.
gnus-select-newsgroup: Couldn’t request group nnir:nnir-87twot20z4.fsf: Search produced empty results.
--8<---------------cut here---------------end--------------->8---

even though

--8<---------------cut here---------------start------------->8---
notmuch search --format=text --output=files roger
--8<---------------cut here---------------end--------------->8---

gives me a long list of files like:

--8<---------------cut here---------------start------------->8---
/home/wilk/email/Local/LLG_2010-2011/1
/home/wilk/email/Local/LLG_2009-2010/2
--8<---------------cut here---------------end--------------->8---

That is all I have in my configuration, yes.

Can you read those from Gnus? I.e. do they belong to a group in Gnus?

My versions:

 GNU Emacs 24.5.1 (x86_64-pc-linux-gnu, GTK+ Version 3.18.2) of 2015-11-07 on trouble, modified by Debian
 Ma Gnus v0.14 (965fb88)
 notmuch 0.21


  Best regards,

Here are mine

GNU Emacs 25.0.50.2 (x86_64-pc-linux-gnu, GTK+ Version 3.14.13) of 2015-10-21
"Ma Gnus v0.14" (latest from git as of tonight)
notmuch 0.20.2

I'll try updating notmuch.

Regards,

Julien.

Curiouser and curiouser. What backend do you use to access them?

I guess you'll have to debug this further, say by using M-x edebug-defun
on some relevant nnir.el functions.

nnir-notmuch-remove-prefix isn't a group parameter?

I finally could fix it: my nnml was stored in ~/email/Local/ so notmuch
had to remove some prefix (which it didn't need to in your setup since
yours is in ~/Mail)

The following is working

--8<---------------cut here---------------start------------->8---
(setq gnus-select-method 
      '(nnml "Local"
	     (nnml-directory "~/email/Local")
	     (nnml-active-file "~/email/Local/active")
	     (nnml-get-new-mail nil)
	     (nnir-search-engine notmuch)
	     (nnir-notmuch-remove-prefix "/home/wilk/email/Local/")
	     )
      )
--8<---------------cut here---------------end--------------->8---

However, I also have 2 Maildirs (in /home/wilk/email/Maildir/Free for
instance) along with the nnml folder, and I wanted to try notmuch on
them too. I have set up some secondary methods like:

--8<---------------cut here---------------start------------->8---
(setq gnus-secondary-select-methods
      '(
	(nnimap "FreeOffline"
		(nnimap-stream shell)
		;; (nnimap-shell-program "/usr/lib/dovecot/imap -c /home/wilk/.dovecotrc-free")
		(nnimap-shell-program "/usr/lib/dovecot/imap -o mail_location=maildir:$HOME/email/Maildir/Free:LAYOUT=fs")
		(nnimap-split-methods default)
		(nnimap-inbox "INBOX")
		(nnir-search-engine notmuch)
		(nnir-notmuch-remove-prefix "/home/wilk/email/Maildir/Free/")
		)
)
--8<---------------cut here---------------end--------------->8---

but nnir-notmuch-remove-prefix seems to be always set to the value
defined in the primary method. So I guess that
nnir-notmuch-remove-prefix is not a group parameter. It would make sense
that it were, don't you think ?

For the time being I'll stick to the imap engine for nnir on the
maildir.

Julien.

Ah, great!

Sounds like it. The documentation says it is a regex, so you can
probably work around the problem by making the value match both
prefixes?

,----[ C-h v nnir-notmuch-remove-prefix RET ]
| nnir-notmuch-remove-prefix is a variable defined in `nnir.el'.
| Its value is "/home/asjo/Mail/"
| 
| Documentation:
| *The prefix to remove from each file name returned by notmuch
| in order to get a group name (albeit with / instead of .).  This is a
| regular expression.

Thanks, it's working for both nnimap and nnml at the same time.

Actually it doesn't, I lost track of what I was using. With:

--8<---------------cut here---------------start------------->8---
(setq nnir-notmuch-remove-prefix (regexp-opt '("/home/wilk/email/Local/" "/home/wilk/email/Local/archive/" "/home/wilk/email/Maildir/Free/")))
--8<---------------cut here---------------end--------------->8---

nnir using notmuch doesn't return any results when searching a message
in the nnimap or nnml located respectively at
/home/wilk/email/Maildir/Free/ and /home/wilk/email/Local/

With

--8<---------------cut here---------------start------------->8---
(setq nnir-notmuch-remove-prefix "/home/wilk/email/Local/")
--8<---------------cut here---------------end--------------->8---

Searching in the nnml backend works.
