vt102 0.4

Simple vt102 emulator, useful for screen scraping.

vt102 implements a subset of the vt102 specification (the subset that should be most useful for use in software). Two classes: stream, which parses the command stream and dispatches events for commands, and screen which, when used with a stream maintains a buffer of strings representing the screen of a terminal.

Why would you ever want to use this?

• Screen scraping.

• Cheating at nethack (I swear to god I will ascend)

• Chicks dig terminals, and err… VT?

Here’s a quick example:

>>> from vt102 import screen, stream
>>> st = stream()
>>> sc = screen((10, 10))
["          ",
 "          ",
 "          ",
 "          ",
 "          ",
 "          ",
 "          ",
 "          ",
 "          ",
 "          "]
>>> sc.attach(st)
>>> st.process("Text goes here")
>>> repr(sc)
["Text goes ",
 "here      ",
 "          ",
 "          ",
 "          ",
 "          ",
 "          ",
 "          ",
 "          ",
 "          "]
>>> st.process("\x1b[H\x1b[K")
>>> repr(sc)
["          ",
 "here      ",
 "          ",
 "          ",
 "          ",
 "          ",
 "          ",
 "          ",
 "          ",
 "          "]
