# advanced.mushrc
# by Bart Schaefer
# with special thanks to Phil Lapsley <phil@east.Berkeley.EDU>, who
# provided the original files on which this example is based.  Most of
# Phil's stuff is still here -- just reorganized and updated to use
# mush 6.4 features that were unavailable when Phil did the originals.
#
# This file is intended to demonstrate helpful ways to use the
# .mushrc, not advanced mush commands.

# The variable $thisfolder is always set EXCEPT when the .mushrc file
# is read the first time.  A test for non-existance of $thisfolder
# allows the same .mushrc file to be sourced repeatedly without
# redundant execution of the initialization commands.
#
if ! $?thisfolder
    # Ignore the usual stuff
    ignore	received via message-id status priority
    # Hide folders in ~/.mail and save read mail in spool
    set		folder=~/.mail hold
    # Remember a few commands, set up editors, act like a shell
    set		history=20 editor=ex visual=vi unix
    # Prompt has folder name, message number, history number
    set		prompt="%f %m (!) & "
    # Header summaries show name, date, and subject
    set		hdr_format="%25n %-15d  %27s"
    # Initialize the cmds below (see later comments)
    set		first_time=1

    # These two commands are used for automated "bursting" of the spool
    # mailbox.  This means that the messages are reorganized into new
    # folders to be read in a prearranged order.  See comments below.
    #
    # n brings up the next folder, not the next message
    cmd		n	'source ~/.mushrc'
    # N gets the next folder without "bursting"
    cmd		N	'set first_time=0; source ~/.mushrc'

    # Delete messages by pattern-matching.  Examples:
    #  del f mailer-daemon		Delete mail from mailer-daemon
    #  del t mush-users			Delete mail to mush-users
    cmd		del	'pick -i -\!* | delete'
    # Forwarding
    cmd		for	'mail -f'
    # Quick folder change
    cmd		F	'folder'

    # Some useful aliases
    alias	dheller	'The Mush God <argv@sun.com>'
    alias	barts	'Archangel Mushael <schaefer@cse.ogi.edu>'

    # On init, don't source beyond this point
    exit
endif	# End of init section -- read on startup only

# This part of the file handles "bursting".  A burst is done when the
# n cmd is used the first time.  This is most useful if you habitually
# have lots of mail when you first log in each morning; unwanted mail
# can be deleted, and other mail organized for you.
#
# The folders in this example bursting scheme are:
#	mush-users	anything to or cc'ed to mush-users
#	stats		daily stats
#	root		root mail other than daily stats
# Mail not falling into one of these categories is left in the system
# mailbox to be dealt with first.
