# This is a simple script that make use of CFDialog.py and receive it's
|
|
# parameters from a JSON inside the event message. Alternativey, the JSON
|
|
# parameters, if >= 4096 characters, can be stored in a file that will be
|
|
# loaded. Use the classical script parameter to specify relative location
|
|
# of dialog.
|
|
# exemple
|
|
#{
|
|
# "location" : "test_grandpa_01",
|
|
# "rules": [
|
|
# {
|
|
# "match" : "hello|hi",
|
|
# "pre" : [["hello","0"]],
|
|
# "post" : [["hello","1"]],
|
|
# "msg" : ["Hello, lad!","Hi, young fellow!","Howdy!"]
|
|
# },
|
|
# {
|
|
# "match": "hello|hi",
|
|
# "pre" :[["hello","1"]],
|
|
# "post" :[["hello", "*"]],
|
|
# "msg" : ["I've heard, you know, I'm not deaf *grmbl*"]
|
|
# },
|
|
# {
|
|
# "match" : "*",
|
|
# "pre" : [["hello","*"]],
|
|
# "post" : [["hello", "*"]],
|
|
# "msg" : ["What ?", "Huh ?", "What do you want ?"]
|
|
# }
|
|
#]}
|
|
# The pre and post in rule are variable to test and set depending on that dialog rule.
|
|
# For example, first rule applie if "hello" is set to "0" (default) and immediatly
|
|
# sets it to "1" when rule is used.
|
|
# the Double [ around pre and post are needed. The pre and post are
|
|
# arrays of arrays. Each item in pre and post is an array of [variable,value]
|
|
# The match is the rule to apply to what user says
