For example, the ANSI color and ANSI escape sequences that MUVEs use.

ANSI escape sequence

A sequence of special characters that sends a command to a device or program. Typically, an escape sequence begins with an escape character, but this is not universally true. MUVEs often use ANSI escape sequences to treat text with color and style information.

Short for Carriage Return / LineFeed, a carriage return is a special code that moves the cursor to the beginning of the current line. Linefeed moves the cursor to the next line. Some MUVE servers detect the end of a line of input using a CR, others use a CR and LF (CR/LF). Savitar supports both types.

Nowadays, the term is used more generically to refer to any cyberspace.

A terminal emulation program for TCP/IP networks such as the Internet. A standard agreed-upon communication protocol between clients and servers for exchanging text information. Savitar supports a subset of this protocol.


Savitar supports the concept of "triggers", allowing you to set up interesting reactions that are triggered on one or more words that are received from the connected world (known as an output trigger), or one or more words you have typed in the world input pane (known as an input trigger).  You can even create triggers which operate on both input and output. Triggers can do all sorts of things like highlighting text, making a sound, or sending and automatic reply.

When Savitar encounters a variable marker in a line of input, it will substitute the %%<variable-name> with the variable's value.
