.IX Title "RIVESCRIPT 1p"
.TH RIVESCRIPT 1p "2012-05-29" "perl v5.14.2" "User Contributed Perl Documentation"
.\" For nroff, turn off justification.  Always turn off hyphenation; it makes
.\" way too many mistakes in technical documents.
.if n .ad l
.nh
.SH "NAME"
rivescript \- A command line frontend to the Perl RiveScript interpreter.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&  $ rivescript [options] [path to RiveScript documents]
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is a command line front-end to the RiveScript interpreter. This script
obsoletes the old \f(CW\*(C`rsdemo\*(C'\fR, 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.
.PP
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.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\-\-debug, \-d" 4
.IX Item "--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 \f(CW\*(C`\-\-log\*(C'\fR option
instead of \f(CW\*(C`\-\-debug\*(C'\fR.
.IP "\-\-log \s-1FILE\s0" 4
.IX Item "--log FILE"
Enables debug mode and prints the debug output to \f(CW\*(C`FILE\*(C'\fR instead of to your
terminal.
.IP "\-\-json, \-j" 4
.IX Item "--json, -j"
Runs \f(CW\*(C`rivescript\*(C'\fR in \s-1JSON\s0 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 \*(L"\s-1JSON\s0 Mode\*(R" for details.
.IP "\-\-strict, \-\-nostrict" 4
.IX Item "--strict, --nostrict"
Enables strict mode for the RiveScript parser. It's enabled by default, use
\&\f(CW\*(C`\-\-nostrict\*(C'\fR to disable it. Strict mode prevents the parser from continuing
when it finds a syntax error in the RiveScript documents.
.IP "\-\-depth=50" 4
.IX Item "--depth=50"
Override the default recursion depth limit. This controls how many times
RiveScript will recursively follow redirects to other replies. The default is
\&\f(CW50\fR.
.IP "\-\-help" 4
.IX Item "--help"
Displays this documentation in your terminal.
.SH "USAGE"
.IX Header "USAGE"
.SS "Interactive Mode"
.IX Subsection "Interactive Mode"
This is the default mode used when you run \f(CW\*(C`rivescript\*(C'\fR without specifying
another mode. This mode behaves similarly to the old \f(CW\*(C`rsdemo\*(C'\fR script and lets
you chat one-on-one with your RiveScript bot.
.PP
This mode can be used to test your RiveScript bot. Example:
.PP
.Vb 1
\&  $ rivescript /path/to/rs/files
.Ve
.SS "\s-1JSON\s0 Mode"
.IX Subsection "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 \s-1JSON\s0.
.PP
Example:
.PP
.Vb 1
\&  $ rivescript \-\-json /path/to/rs/files
.Ve
.PP
The format for incoming \s-1JSON\s0 data is as follows:
.PP
.Vb 7
\&  {
\&    "username": "localuser",
\&    "message":  "Hello bot!",
\&    "vars": {
\&      "name": "Aiden"
\&    }
\&  }
.Ve
.PP
Here, \f(CW\*(C`username\*(C'\fR is a unique name for the user, \f(CW\*(C`message\*(C'\fR is their message to
the bot, and \f(CW\*(C`vars\*(C'\fR is a hash of any user variables your program might be
keeping track of (such as the user's name and age).
.PP
The response from \f(CW\*(C`rivescript\*(C'\fR will look like the following:
.PP
.Vb 7
\&  {
\&    "status": "ok",
\&    "reply":  "Hello, human!",
\&    "vars": {
\&      "name": "Aiden"
\&    }
\&  }
.Ve
.PP
Here, \f(CW\*(C`status\*(C'\fR will be \f(CW"ok"\fR or \f(CW"error"\fR, \f(CW\*(C`reply\*(C'\fR is the bot's response to
your message, and \f(CW\*(C`vars\*(C'\fR is a hash of the current variables for the user (so
that your program can save them somewhere).
.PP
\fIEnd of Message\fR
.IX Subsection "End of Message"
.PP
There are two ways you can use the \s-1JSON\s0 mode: \*(L"fire and forget,\*(R" or keep a
stateful session open.
.PP
In \*(L"fire and forget,\*(R" you open the program, print your \s-1JSON\s0 input and send the
\&\s-1EOF\s0 signal, and then \f(CW\*(C`rivescript\*(C'\fR sends you the \s-1JSON\s0 response and exits.
.PP
In a stateful session mode, you must send the text \f(CW\*(C`_\|_END_\|_\*(C'\fR on a line by
itself after you finish sending your \s-1JSON\s0 data. Then \f(CW\*(C`rivescript\*(C'\fR will
process it, return its \s-1JSON\s0 response and then also say \f(CW\*(C`_\|_END_\|_\*(C'\fR at the end.
.PP
Example:
.PP
.Vb 6
\&  {
\&    "username": "localuser",
\&    "message": "Hello bot!",
\&    "vars": {}
\&  }
\&  _\|_END_\|_
.Ve
.PP
And the response:
.PP
.Vb 6
\&  {
\&    "status": "ok",
\&    "reply": "Hello, human!",
\&    "vars": {}
\&  }
\&  _\|_END_\|_
.Ve
.PP
This way you can reuse the same pipe to send and receive multiple messages.
