# Startup macros for 'rn'. Should reside in the file ".rnmac"
# in your home directory (or your DOT directory, if you do it
# that way). These macros allow pre-processing of KILL files,
# among other things.

# This is best invoked by running 'rn' and piping the letter 'z'
# into the thing until it pukes:
# yes z | rn >& /dev/null
# The idea is that by always typing 'z', you will always enter each
# newsgroup that has unread news (which will cause the KILL file to
# be processed for that group), but will exit immediately after that,
# and then duck into the next newsgroup. This will continue until
# the last newsgroup is entered and exited, at which point you will
# quit 'rn'. The point of having the 'z' key do all these different
# things is so that you don't have to pay attention to where you are,
# and you can use the above-mentioned command line to process the KILL
# files *before* you read the news, so you save lots of search time.
# I originally intended this to be run in the background at some
# random time, so that I would never have to know about the KILLed
# articles, but I have discovered that is great fun to just type:
# yes | rn
# and watch the thing cycle through the newsgroups, blowing away all
# those hated articles. In fact, it is arguably much more fun than
# actually reading the news.
# NOTE: These macro names are ridiculous and are chosen
# so that they do not conflict with any standard 'rn' bindings.
# The 'driver' macro is the 'z' macro (last here), and you should
# really start reading there, since it calls the other macros as
# necessary.
# the '*' macro is called by 'Z', quits if last newsgroups, otherwise 'y'..
# the condition %C=$ returns TRUE if the current newsgroup (in dot mode)
# is the last newsgroup (i.e. "End of newsgroups--what next? [npq]")
* %(%C=$?q:y)
# the 'Z' macro is called by 'z', calls '*' if there are unread articles...
# the %u=0 condition returns TRUE if there are no 'unread articles' in
# the current newsgroup.
Z %(%u=0?q:^(*^))
# the 'z' macro returns 'q' in any mode other than newsgroup selection mode,
# wherein it calls the 'Z' macro...
# the %m!=n means: "if mode is not 'newsgroup selection' mode"
# the ? clause is executed if condition is TRUE, the : clause otherwise
# the godawful ^( ^) syntax is required by 'rn' to be able to call a
# macro by name on the right-hand side of another macro. Otherwise no
# expansion is done.
