Package zzcsi implements the Control Sequence Introducer (CSI) functions supported by Xterm-compatible terminals. The most commonly used functions are to erase a line or the screen, manipulate the cursor or set the display attributes such as foreground and background colors, bold or italics, but many more functions are available. See the xterm documentation for more information on CSI sequences.
This is a package in the zzterm family of Go packages, which aim to help build terminal-based programs with a focus on speed and memory efficiency.
When using a buffer of sufficient capacity,
CSI.AppendFunc can append the
CSI escape sequence without allocation.
