# These lines that start with the '#' are called comments. They don't affect the way the code runs.
# In this tutorial file, I put comments above the relevant lines.

# 1. Before we begin. Caster Rules should be placed in [Caster User Directory](https://caster.readthedocs.io/en/latest/readthedocs/User_Dir/Caster_User_Dir/) `rules` directory. See hyperlink for directory file path based on OS. The `rules` folder is where all your created rules should be stored. This folder can be summoned by voice say `bring me caster rules` If Caster is running. 
# The function 'get_rule()' that loads this rule is commented out. Therefore will cause it to never run.
# You will need to scroll to the very end of the file and uncomment the following:

# def get_rule():
#     return MyRule, RuleDetails(name="my rule")

# 2. Now that it's uncommented simply start/restart Caster. 
# 3. To enable the rule, say "enable my rule" 

# You can skip down to the next comment, for now this is not important...

    # In the next line, there are two things to observe:
    # 1. The use of parentheses and the pipe symbol ( | ) lets me use either "motel" or "lodging" to trigger that command.
    # 2. The playback action, lets me tell the speech recognition engine to simulate me speaking some words.

    # If you need to do more complicated tasks, or use external resources, a function might be what you need.

    # The angle brackets <> meaning I'm using an extra, and the square brackets [] mean that I don't have to speak that word, it's optional.
    # Advice: if you use an optional extra, like I am with "text", you should set a default value  in the defaults section down below.
