# Simple menuing system to execute scripts in $HOME/bin/menu1_items
# code portions courtesy https://pypi.org/project/simple-term-menu/
# (actually I did not ask the guy, I just copied some portions of his code 🤪 )
# I suggest putting at least one script call z_Quit in
# $HOME/bin/menu1_items
# The z_Quit file should be executable (eg chmod +x)
# and should simply contain:
# #!/bin/sh
# echo "Exiting"
# Doing it this way is a simple exit and also avoids crashes if
# menu1 is called and menu1_items is an empty directory.

# this is where scripts go, change it to suit your needs
ITEMS_DIR = HOME_DIR + '/bin/menu1_items/'
# Comment this out if you don't want the screen cleared every time
subprocess.call('clear')
menu_title = 'Please select action: \n'
# if you don't want previews remove 'preview_command' from invocation
# of TerminalMenu below
preview = "cat " + ITEMS_DIR + "{}"
