NAME

       rivescript - A command line frontend to the Perl RiveScript interpreter.

SYNOPSIS

	 $ rivescript [options] [path to RiveScript documents]

DESCRIPTION

       This is a command line front-end to the RiveScript interpreter. This script obsoletes the old "rsdemo", and can also be used non-
       interactively by third party programs. To that end, it supports a variety of input/output and session handling methods.

       If no RiveScript document path is given, it will default to the example brain that ships with the RiveScript module, which is based on the
       Eliza bot.

OPTIONS

       --debug, -d
	   Enables debug mode. This will print all debug data from RiveScript to your terminal. If you'd like it to log to a file instead, use the
	   "--log" option instead of "--debug".

       --log FILE
	   Enables debug mode and prints the debug output to "FILE" instead of to your terminal.

       --json, -j
	   Runs "rivescript" in JSON mode, for running the script in a non-interactive way (for example, to use RiveScript in a programming
	   language that doesn't have a native RiveScript library). See "JSON Mode" for details.

       --strict, --nostrict
	   Enables strict mode for the RiveScript parser. It's enabled by default, use "--nostrict" to disable it. Strict mode prevents the parser
	   from continuing when it finds a syntax error in the RiveScript documents.

       --depth=50
	   Override the default recursion depth limit. This controls how many times RiveScript will recursively follow redirects to other replies.
	   The default is 50.

       --help
	   Displays this documentation in your terminal.

USAGE

   Interactive Mode
       This is the default mode used when you run "rivescript" without specifying another mode. This mode behaves similarly to the old "rsdemo"
       script and lets you chat one-on-one with your RiveScript bot.

       This mode can be used to test your RiveScript bot. Example:

	 $ rivescript /path/to/rs/files

   JSON Mode
       This mode should be used when calling from a third party program. In this mode, data that enters and leaves the script are encoded in JSON.

       Example:

	 $ rivescript --json /path/to/rs/files

       The format for incoming JSON data is as follows:

	 {
	   "username": "localuser",
	   "message":  "Hello bot!",
	   "vars": {
	     "name": "Aiden"
	   }
	 }

       Here, "username" is a unique name for the user, "message" is their message to the bot, and "vars" is a hash of any user variables your
       program might be keeping track of (such as the user's name and age).

       The response from "rivescript" will look like the following:

	 {
	   "status": "ok",
	   "reply":  "Hello, human!",
	   "vars": {
	     "name": "Aiden"
	   }
	 }

       Here, "status" will be "ok" or "error", "reply" is the bot's response to your message, and "vars" is a hash of the current variables for
       the user (so that your program can save them somewhere).

       End of Message

       There are two ways you can use the JSON mode: "fire and forget," or keep a stateful session open.

       In "fire and forget," you open the program, print your JSON input and send the EOF signal, and then "rivescript" sends you the JSON
       response and exits.

       In a stateful session mode, you must send the text "__END__" on a line by itself after you finish sending your JSON data. Then "rivescript"
       will process it, return its JSON response and then also say "__END__" at the end.

       Example:

	 {
	   "username": "localuser",
	   "message": "Hello bot!",
	   "vars": {}
	 }
	 __END__

       And the response:

	 {
	   "status": "ok",
	   "reply": "Hello, human!",
	   "vars": {}
	 }
	 __END__

       This way you can reuse the same pipe to send and receive multiple messages.
