pyte

pyte is 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. pyte follows the suit.

So, why would one need a terminal emulator library?

- To screen scrape terminal apps, for example htop or aptitude.
- 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.

Note: pyte started as a fork of vt102, which is an incomplete implementation of VT100 features.

Installation

If you have setuptools you can use easy_install -U pyte. Otherwise, you can download the source from GitHub and run python setup.py install.

Example

 >>> import pyte
 >>> screen = pyte.Screen(80, 24)
 >>> stream = pyte.Stream()
 >>> stream.attach(screen)
 >>> stream.feed(u"\u001b7\u001b[?47h\u001b)0\u001b[H\u001b[2J\u001b[H"
