class TermBuf::BufferSurface

Overview

A drawing surface that writes into a buffer as commands arrive.

The core layer's answer to Terminal: everything built on Drawing works against it, with no device, no fibres, and nothing to tear down afterwards.

Class Method Detail

def self.apply(command : Command, buffer : Buffer) : Bool #

Applies the commands that need nothing but a buffer, and reports whether command was one of them.

A class method because the owning fibre needs the same lines and has its own reasons to keep hold of the ones this leaves alone.
