Enclosed is a shell script to allow Mush to be used for 'r'eplying to news
articles from within the RN newsreader. It was previously sent to the
mush-users mailing list, but this version includes several corrections.
If you picked up the mush-users copy, I recommend you replace it with this.
The script is presently configured for mush 6.5, but all the guts needed
for 6.4 are present in comments, so if you don't have the upgrade kit you
can rip out the 6.5 pieces and uncomment the 6.4 pieces. The sections that
will need changing both (yes, only two) look like
# Use this {line,section} for mush 6.4
# ... block comment
# hiding some commands ...
# Change to this new {line,section} for mush 6.5
... other commands ...
so it shouldn't be hard to find them to convert.
The 6.4 version works by turning the headers of the -h file into a bunch
of my_hdr commands that are then fed to mush. That means you can't
change any of them except To: Cc: Bcc: and Subject: (which you edit with
tilde-escapes as usual). 6.4 users can expect a few error messages that
result from things like the blank Cc: and Bcc: that RN adds by default.
Also, RN's headers will overwrite any that you set in your .mushrc.
The 6.5 version merges the headers of the -h file with those generated by
mush, and edit_hdrs allows you to change any of them. Mush nicer. :-)
As noted in the preliminary comments below, both versions create a shell
script which is used by mush as $visual. If you "set visual" in mush to
something other than your environment $VISUAL, you will find that you
don't get the editor you expect.
To use Rnmush to send replies from RN:
setenv MAILPOSTER "Rnmush -h %h"
To use Rnmush to post news articles:
This is a little trickier. The main thing needed is that Rnmush must
be modified to add
$echo 'set sendmail="inews -h"' >> $start
near the beginning, right after the $echo that sets autoedit and so
on. Note that this makes it useless for replies, so you probably
want to make a new copy called Pmush for this modification. Then, if
you use
setenv NEWSPOSTER "Pmush -h %h"
you have a minimal follow-up news poster. However, that does not go
far enough to replace Pnews as it works when invoked from the shell.
For that, the $start file needs a bunch of my_hdr commands to set the
Newsgroups:, Distribution:, Keywords:, etc. headers, and they must be
set to *something* because mush will reject empties. (For the 6.5
version, these headers could be added to the $tmpart file before mush
is called, and then it doesn't matter if they are empty.)
If somebody actually hacks up a fully functional Pmush, send it out. :-)
