Terminal protocol extensions¶
kitty has extensions to the legacy terminal protocol, to enable advanced features. These are typically in the form of new or re-purposed escape codes. While these extensions are currently kitty specific, it would be nice to get some of them adopted more broadly, to push the state of terminal emulators forward.
The goal of these extensions is to be as small and unobtrusive as possible, while filling in some gaps in the existing xterm protocol. In particular, one of the goals of this specification is explicitly not to “re-imagine” the tty. The tty should remain what it is – a device for efficiently processing text received as a simple byte stream. Another objective is to only move the minimum possible amount of extra functionality into the terminal program itself. This is to make it as easy to implement these protocol extensions as possible, thereby hopefully encouraging their widespread adoption.
If you wish to discuss these extensions, propose additions/changes to them please do so by opening issues in the GitHub bug tracker.
