beamtea_runtime (beamtea v0.1.2)

The event loop that owns the terminal and drives an Elm program.

This process is the one that initialises prim_tty, so it must be registered (prim_tty derives its reader/writer process names from the owner's registered name). beamtea:start/3 takes care of that.

Lifecycle:

put the tty in raw mode, enter the alternate screen, hide cursor
run init/1, render the first frame, arm the reader
loop: decode input into keys, feed messages to update/2, run the returned commands, repaint
on quit/eof/crash: show cursor, leave the alternate screen and restore cooked mode — always, via after
