nnmaildir does not 'read' maildir archive

[Saša Janiška]

Hello,

I'm in the process of migrating my Evolution/vim/takswarriot setup to
(spac)Emacs/org-mode/Gnus and more or less I am now able to send/receive
my mail/news with Gnus, using multiple IMAP accounts, signing messages
etc. but have problem with reading my old Maildir archive...

My archive is organized as subfolders (per year) under ~/Maildir, e.g.

$ ls -al Maildir/
total 100
drwx------ 1 gour gour 1548 Vel  5 17:15 ./
drwxr-xr-x 1 gour gour 1992 Vel  5 19:42 ../
drwx------ 1 gour gour   18 Lis 30 08:43 .archive/
drwx------ 1 gour gour   18 Lis 30 08:43 .archive.1994/
-rw-r--r-- 1 gour gour   13 Vel  5 17:15 .archive.1994.cmeta
drwx------ 1 gour gour   18 Lis 30 08:44 .archive.1995/
-rw-r--r-- 1 gour gour   13 Vel  5 17:15 .archive.1995.cmeta
...


and I cp-ed two folders like:

$ ls -al .nnmaildir/
total 0
drwxr-xr-x 1 gour gour  32 Vel  5 19:51 ./
drwxr-xr-x 1 gour gour 142 Vel  4 11:54 ../
drwx------ 1 gour gour  38 Vel  5 18:55 1994/
drwx------ 1 gour gour  38 Vel  5 18:55 1995/
drwxr-xr-x 1 gour gour  12 Vel  4 14:11 .notmuch/

(I plan to use notmuch as search engine with nnnir.)


Here is the snippet from my Gnus file:

(setq gnus-secondary-select-methods
      '(
          ;; nnimap methods...
          
          (nntp "vipnews"
                (nntp-address "news.vip.hr")
                (nnir-search-engine nntp))
          (nnmaildir "archive"
                     (directory "~/.nnmaildir/")
                     (directory-files nnheader-directory-files-safe)
                     (get-new-mail nil)
                     (nnir-search-engine notmuch))

After I start Gnus, I see that {1994, 1995} subfolders are populated
with :

$ ls -al .nnmaildir/1994/
total 0
drwx------ 1 gour gour   38 Vel  5 18:55 ./
drwxr-xr-x 1 gour gour   32 Vel  5 19:51 ../
drwx------ 1 gour gour 4540 Lis 30 08:55 cur/
drwx------ 1 gour gour    0 Lis 30 08:43 new/
drwxr-xr-x 1 gour gour   22 Vel  5 18:55 .nnmaildir/
drwx------ 1 gour gour    0 Lis 30 08:44 tmp/

'.nnmaildir' folder, but nothing is visible in the Group buffer.

Any hint what do I miss?


Sincerely,
Gour
