CV

I'm a professional programmer/musician. I'm mostly here for the code and somewhat for the insanity :) I'm literate in most major languages with a bias to C++, Python, Smalltalk and Lisp and I'm a *nix head from way back; yeah BL (Before Linux). Don't ask me anything about Windoze.

SLIR

I am working on a server system in my spare time. LibSL, opensim and Pyogp are great projects in which I participate in as much as I can but, for my own purposes and education, I am building this system in Ruby. At the moment I call it 'SLIR' which means absolutely nothing or possibly Second Life Interactive Ruby, or even So Little Interesting Real-Work, I don't know for sure. I had a python implementation of this as well but Pyogp kind of made that moot. I plan on releasing the SLIR code as soon as I can get the viewer to login and logout without complaining.

SL

I run a scripting/gadget biz in SL under the handle Kwerks but mainly do custom work. Feel free to give me a buzz if you have something on your mind. The lab is in Alleni/66/190/31.

Offline LSL Syntax Checker

I use this to do a quick syntax check on LSL files from my normal editors (emacs or TextMate) when I am offline. To build this you must have the viewer source installed and built on your machine. I built it on OS/X so Linux will probably be fine and I have no clue how to make it go on windows. If you get it to run on windows send me the instructions and I will post them here.

*
* Created by JB Kraft.
*
* A small utility to use as a syntax check for LSL scripts outside of 
* Second Life. I built this on OS/X. YMMV.
*
* Building:
* - you need the source code for the viewer installed and compiled on your 
*   machine
* - create a makefile or project or whatever you do and compile this code and
*   link it against libapr-?.a, libllcommon.a
*
* Command line:
* ./lslchecker [FILES...]
