###
# This script demonstates the fvwm menu MissingSubmenuFunction functionality.
# You can use a more configurable fvwm-menu-directory instead.
# The line below almost exactly simulates this script:
# fvwm-menu-directory --links --order 4 --exec-file vi --dir DIR
###
#
# Modification History
#
# Created on 06/07/99 by Dominik Vogt (domivogt):
#
# provides output to read in with PipeRead to build a menu
# containing a directory listing.
#
# You should put these lines into your fvwm configuration file to invoke
# this script:
#
# AddToFunc MakeMissingDirectoryMenu
# + i piperead 'fvwm_make_directory_menu.sh '$0
#
# And put these lines in the menu from which you want to pop up the
# directory menus:
#
# AddToMenu SomeMenu MissingSubmenuFunction MakeMissingDirectoryMenu
# + "my directory item" Popup /whatever/path/you/like
#
# Note: please use absolute path names.
#
# configuration section
#
# If you want to optimize for speed, unset this variable. Warning: speed
# optimization takes up a lot of memory that is never free'd again while fvwm
# is running.

# you may use the absolute path here if you have an alias like ls="ls -F"
LS="/bin/ls -LF"
SED=sed
# the name of our menu
MENU=`echo $1 | $SED -e 's://*:/:g'`
PMENU=`echo "$MENU" | $SED -e s:\"::g`
# the command to execute on plain files
ACTION=vi
# the terminal program to invoke
TERMINAL="xterm -e"
TERMINALSHELL="xterm"
#
# you may customize this script below here.
#
# dump all menu items
