`pyte` implements a mix of VT100, VT220 and VT520 specification,
|
|
and aims to support most of the `TERM=linux` functionality.
|
|
|
|
Two classes: :class:`~pyte.streams.Stream`, which parses the
|
|
command stream and dispatches events for commands, and
|
|
:class:`~pyte.screens.Screen` which, when used with a stream
|
|
maintains a buffer of strings representing the screen of a
|
|
terminal.
|
|
|
|
.. warning:: From ``xterm/main.c`` "If you think you know what all
|
|
of this code is doing, you are probably very mistaken.
|
|
There be serious and nasty dragons here" -- nothing
|
|
has changed.
