ANSI Compatibility

List of ANSI escape sequences that are currently available in Halyde and other related information.

All the commands listed here are only what is capable with the OpenComputers GPU. Most commands outside color are unlisted due to these constraints.

A command must always be on the same string for it to work properly. If a command is cut off, or separated into two strings, this can lead to undefined behavior.
