What is vt102? It's an in memory VTXXX-compatible terminal emulator. XXX stands for a series video terminals, developed by DEC between 1970 and 1995. The first, and probably the most famous one, was VT100 terminal, which is now a de-facto standard for all virtual terminal emulators. vt102 follows the suit.
So, why would one need a terminal emulator library?
- To screen scrape terminal apps, for example
htoporaptitude. - To write cross platform terminal emulators; either with a graphical (xterm, rxvt) or a web interface, like AjaxTerm.
- To have fun, hacking on the ancient, poorly documented technologies.
If you have setuptools you can use easy_install -U vt102. Otherwise, you can download the source from GitHub and run python setup.py install.
>>> import vt102 >>> screen = vt102.Screen(80, 24) >>> stream = vt102.Stream() >>> stream.attach(screen) >>> stream.feed(u"u001b7u001b[?47hu001b)0u001b[Hu001b[2Ju001b[H" u"u001b[2;1HNetHack, Copyright 1985-2003ru001b[3;1" u"H By Stichting Mathematisch Centrum and M.

vt102 is not alone in the weird world of terminal emulator libraries, here's a few other options worth checking out: Termemulator, pyqonsole, webtty AjaxTerm
