package install_steps_interactive;

# heritate from this class and you'll get all made interactivity for same steps.
# for this you need to provide 
# - ask_from_listW(o, title, messages, arrayref, default) returns one string of arrayref
# - ask_many_from_listW(o, title, messages, arrayref, arrayref2) returns one string of arrayref
#
# where
# - o is the object
# - title is a string
# - messages is an refarray of strings
# - default is an optional string (default is in arrayref)
# - arrayref is an arrayref of strings
# - arrayref2 contains booleans telling the default state, 
#
# ask_from_list and ask_from_list_ are wrappers around ask_from_biglist and ask_from_smalllist
#
# ask_from_list_ just translate arrayref before calling ask_from_list and untranslate the result
#
# ask_from_listW should handle differently small lists and big ones.
