1.NOFFLE Compatibility Notes
----------------------------


1.1 General
-----------

Subscribing to groups in "full" mode should work with any news reader.
Caching of articles is unnecessary, since NOFFLE already caches them and
should be switched off.

Subscribing to groups in "overview" or "thread" mode requires more from the
news reader program:

 * It must not cache articles at all (or allow to switch the cache off),
   because the article bodies change from the pseudo article
   "marked for download" to the real body.

 * The reader should rarely open article bodies automatically, because it will
   mark them unwantedly for download.


Here comes a list with news readers that have been tested with NOFFLE,
especially with regards to subscribing to groups in "overview" or "thread"
mode.

Please send me reports on your experiences. If a reader does not work
at all, add 'log-debug all' to noffle.conf, You will then see every
NNTP command and status line in /var/log/news (or wherever the system
log news debug output ends up). Most interesting is the last line,
before the reader (or NOFFLE) hangs :-) Please also send me a short
mail, if you successfully used NOFFLE with a certain version of a news
reader for a longer time, so that I can keep this list up-to-date.


1.2 kexpress
------------

Version 0.2.0;

I found no way to disable caching, apart from writing a wrapper script, which
removes all files from the cache after terminating kexpress:

#!/bin/bash
# kexpress wrapper, save as /usr/local/bin/kexpress

/opt/kde/bin/kexpress $@
rm $HOME/.kde/share/apps/kexpress/data/*


1.3 krn
-------

Version 0.4.0:

Set "Options/NNTP Options/Connect on Startup,Connect without asking"
and "Options/Expire options/Article bodies/Read=0,UnRead=0" Sometimes
the article bodies remain in the cache, the following wrapper script helps:

#!/bin/bash
# krn wrapper, save as /usr/local/bin/krn

/opt/kde/bin/krn $@
rm $HOME/.kde/share/apps/krn/cache/*

Articles can be marked as read/unread without opening with the middle mouse
button. This version of krn is still unstable.


1.4 Netscape
-------------

Version 3.04:

No cache problems, netscape caches the article overviews, but not the
bodies. It is best to use "Options/Show only Unread Messages" and to
keep requested articles in unread state until their bodies are
downloaded. For avoiding unwanted opening of articles one should first
"Message/Mark Newsgroup read", then open the wanted articles one by
one and mark them as unread again ("Message/Mark as Unread")
immediately after opening.


Version 4.0.5:

Same as with netscape 3.04, but automatically opens the first article
of a listed group and marks it for download thereby. If this bothers
you, choose "View/Hide message". This version of netscape still seems
to be unstable for reading news.


Version 4.5:

As with 4.0.5 "View/Show/Message" can be used to switch off automatic
message display (and marking for download).


1.5 pine
--------

Version 3.96, 4.05:

Ok.


1.6 slrn
--------

Version 0.9.5.2:

Ok. You can change some keybindings, by saving the following script to
~/.slrn.sl and adding "interpret .slrn.sl" at the end of your
~/.slrnrc

   % SLRN script for better interplay with NOFFLE news server.
   % Redefines some keys for opening articles without modifying flags.
   define my_article_linedn()
   {
     call ( "article_linedn" );
     if (is_substr(extract_article_header("X-NOFFLE-Status"), "NOT_DOWNLOADED"))
       set_header_flags( ( get_header_flags() | HEADER_READ ) xor HEADER_READ );
     return;
   }
   define my_scroll_dn()
   {
     call ( "scroll_dn" );
     if (is_substr(extract_article_header("X-NOFFLE-Status"), "NOT_DOWNLOADED"))
       set_header_flags( ( get_header_flags() | HEADER_READ ) xor HEADER_READ );
     return;
   }
   define my_hide_article()
   {
     call ( "hide_article" );
     if (is_substr(extract_article_header("X-NOFFLE-Status"), "NOT_DOWNLOADED"))
       set_header_flags( ( get_header_flags() | HEADER_READ ) xor HEADER_READ );
     return;
   }
   definekey( "my_article_linedn", "\r", "article" );
   definekey( "my_scroll_dn", " ", "article" );
   definekey( "my_hide_article", "h", "article" );


1.7 tin
-------

Version tin pre:

Call with "tin -r" or "rtin". 'K' marks articles/thread as read
without opening them. '-' marks them as unread.


1.8 Emacs Gnus
--------------

Here is a proposal for changing some key-bindings.

   ;; Customising Gnus for use with the NOFFLE news server
   ;; 
   ;;  tick and open article
   ;;          for reading/marking for download
   ;;   scroll article text circular
   ;;          for avoiding automatic opening of next article
   ;;       mark article as read and go to next line
   (defun my-gnus-summary-tick-and-open(n)
     "Tick and open article, so that NOFFLE marks it for download" 
     (interactive "p")
     (gnus-summary-scroll-up n)
     (gnus-summary-mark-article nil gnus-ticked-mark t)
     )
   (defun my-gnus-summary-next-page(n)
     "Next page of article, but do not open next article automatically"
     (interactive "p")
     (gnus-summary-next-page 10 t) ;; Call with argument `circular'.
     )
   (defun my-gnus-summary-mark-read-next-line(n)
     "Mark article as read and go to next line"
     (interactive "p")
     (gnus-summary-mark-article-as-read gnus-read-mark)
     (next-line n)
     )
   (defun my-gnus-summary-mode-hook ()
     (define-key gnus-summary-mode-map "\r"
       'my-gnus-summary-tick-and-open)
     (define-key gnus-summary-mode-map " "
       'my-gnus-summary-next-page)
     (define-key gnus-summary-mode-map "d"
       'my-gnus-summary-mark-read-next-line)
     )
   (add-hook 'gnus-summary-mode-hook 'my-gnus-summary-mode-hook)


1.9 pan
-------

Versions 0.7.6, 0.8.0beta5, 0.8:

Ok.


1.10 trn
--------

Version 3.6:

Ok. Use 'm' to mark an article unread. 'J' (junk) marks an entire thread
as read without examining the rest of the articles in the thread.


1.11 xrn
--------

Version 9.01:

There does not appear to be away to stop the body of the first unread
article in the group from being displayed. Otherwise Ok.


1.12 knews
----------

Version 1.0b.0:

knews issues NEWNEWS with a non-compliant 7 digit date field (Y2K bug?).
It will not see new newsgroups as they appear. knews also regards articles
existing in a group when it joins as read, which makes it a bit tricky
reading the subscription trigger message - try the 'All threads' button.
Apart from that, it does not seem to cache article content other than the
current article, and that is re-read if you click on it in the thread
window.

1.13 knode
----------

Version 0.1.13:

Setting the number of days to cache an article to 0 in Options/Read News
prevents the article being cached between knode sessions.

1.14 Gravity
------------

Version 2.3:

As for the overview/thread mode, caching must be disabled in
View->Global Options->Storage(tab), disable "Retrieve and store article
bodies" and "Store all bodies retrieved for reading".
