+[![Build Status](https://travis-ci.org/jaguilar/vt100.svg?branch=master)](https://travis-ci.org/jaguilar/vt100)

+
+This is a vt100 screen reader. It seems to do a pretty
+decent job of parsing the nethack input stream, which
+is all I want it for anyway.
+
+Here is a screenshot of the HTML-formatted screen data:
+
+![](_readme/screencap.png)
+
+The features we currently support:
+
+* Cursor movement
+* Erasing
+* Many of the text properties -- underline, inverse, blink, etc.
+* Sixteen colors
+* Cursor saving and unsaving
+* UTF-8
+
+Not currently supported (and no plans to support):
+
+* Scrolling
+* Prompts
+* Other cooked mode features
+
+The API is not stable! This is a v0 package.
+
+## Demo
+
+Try running the demo! Install nethack:
+
+    sudo apt-get install nethack
+
+Get this code:
+
+    go get github.com/jaguilar/vt100
+    cd $GOPATH/src/githib.com/jaguilar/vt100
+
+Run this code:
+
+    go run demo/demo.go -port=8080 2>/tmp/error.txt
+
+Play some nethack and check out the resulting VT100 terminal status:
+
+    # From another terminal . . .
+    xdg-open http://localhost:8080/debug/vt100
+
+The demo probably assumes Linux (it uses pty-related syscalls). I'll happily
+accept pull requests that replicate the pty-spawning functions on OSX and 
+Windows.
