<drankin@bohemians.lexington.ky.us> in pkg/9221.
Changes from trn 3.6 to trn 4.0:
o Added a newsgroup selector to make choosing news groups easier
(use the ++ option to turn it off).
o In the selector '\' now is used to execute a command, so if
you had 'c' in your SELECTCHARS, you could still catch-up a
group via \c. It also lets you enter the normal newsgroup
commands from the newsgroup selector, such as unsubscribe
(\u) and goto group (\g). If the command letter is both a
selector command and a newsgroup command, use '\\' to get
the newsgroup command (such as \\O or \\h). Use ':' to apply
a (limited set) of commands to more than one group, such as
":u" (unsubscribe) or ":c" (catchup).
o Use "\v" from any selector to see the current trn version.
o Use the backtick (`) command to switch back and forth between
the newsgroup selector and the rn-style newsgroup browser.
You can also type backtick from inside a newsgroup to exit
back to the newsgroup selection level.
o Use the '=' command in the newsgroup selector to refresh the
article counts (possibly refetching the active file).
o Use the Ctrl-G command in the selector to go to a letter
without affecting it (e.g. "Ctrl-G b" would go to letter 'b').
o Added an addgroup selector to ease the arrival of new groups.
o Strn's article scan/scoring is now present in trn.
o ** Describe the universal selector once it settles down **
o Enabled trn to use both nntp and local news sources, either
separately or at the same time. Create a .trn/access file to
customize this (start with a copy of <trnlib>/access.def).
o Changed the format of trn's option files. Trn will create a
.trn/trnrc file for you using your old trn options as soon as
you edit and save them using the on-line option editor. Once
this happens, the old TRNINIT variable is ignored.
o When you specify a news source in the active file, you can
tell trn to keep a local copy of the server's active and
newsgroups files, and either re-grab them at regular intervals
(however often you like), update them with new information
we glean while running, or leave them alone (which is useful
for an NFS mounted active file).
o Added a newsrc selector to choose among the news sources and
newsrc options in your .trn/access file.
o Alternately, use Ctrl-N and Ctrl-P in the newsgroup selector
or newsgroup browser to change from news source to news source.
o Added an on-line option editor (type '&' <RETURN>). Use the
search command (/erase) to find the option you're looking for.
o Much improved xterm mouse handling now lets you define a
"mouse bar" of buttons to press, as well as allowing you to
click on the tree nodes in the article tree display. Use
the option selector to turn it on and customize it. See
the <trnlib>/INIT file for an example of how to make the
mouse code conditional on your terminal type. You can
even double-click in the selector to start reading and
select a range with click-drag-release.
o Enhanced the mime code so that trn now knows how to handle
basic mime types, and farm out the ones it doesn't understand.
!!Not finished yet!!
o Use the 'a' (attachments) command to view an article's
attachments, including a uuencoded picture in a picture
group. Even works with multi-part pieces if you use 'a'
on all the parts (in any order). Use ":a" to view a
group of selected articles (handy from the selector). Of
course, "::a" affects all unselected articles.
o The header hiding code now hides more headers by default,
and can un-hide any header (prior trns could only hide
known header names plus all unknown headers in a group).
o You can now specify a custom IP port for an NNTP connection
in your .trn/access file or the NNTPSERVER variable.
o A bargraph (for percent done) pops up on slow tasks (such
as fetching the active file over a slow link).
o Changed the default "auto arrows" (-A) to be more web-
browser-like in the selectors. Set option "Auto Arrow
Macros" to "old-style" if you like the old style better.
o A client ("mini") inews is now included with trn that is
compatible with other news readers and a bit more functional.
o Macro writers: each selector has a different mode letter (see
the %m discussion in the man page for a list), but there's
now an easy way to write a macro that affects all selectors
test the "general mode": %g=s. See the man page for the other
general modes.
o Fixed the type-ahead eating to never eat just part of a macro
sequence (such as a keypad key or a mouse click).
o Trn now use X-Newsgroups instead of Newsgroups in mailed replies.
It also uses X-Also-Posted-To when Cc'ing people while posting.
