#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:

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.
