I threw the compiled AGC.dll file in git since it's small, to save you the trouble of monodevelop: https://github.com/joevenzon/kerbal-agc/tree/master/AGC/AGC/bin/Debug Let me know how your missions go!

Transcendental functions have been added: https://github.com/joevenzon/kerbal-agc/commit/33d464409d28d6d7e1c61049a3cededcbb5033fa and I updated the README.md with their names.

For the variable to exist in the parent scope you need to define it there and then set it inside your function: (begin (define AGC.Status 0) ((lambda () (set! AGC.Status (list 1 88)) )) )

Fixed in https://github.com/joevenzon/kerbal-agc/commit/8e4ef3e4c367c7585b8586f4c87b472bb0b645e3

The fact that (define (func) ...) doesn't work is probably a bug. But you can work around it: (define (f x y ...) exp) is actually just converted into (define f (lambda (x y ...) exp)) So if you want to define a function without any variables you should be able to use the lambda syntax directly: (define func (lambda () exp))

It looks like the 0.23 package is compatible with 0.24. I also put the source up on github: https://github.com/joevenzon/kerbal-agc

Here's the comma separated list of built-in functions: if, quote, set!, define, initialize, lambda, begin, +, -, *, /, not, and, or, >, <, >=, <=, =, equal?, eq?, length, cons, car, cdr, append, list, list?, null?, symbol?, defined?, modulo, abs, floor, ceiling, min, max, apply, id, sqrt, let There are also some helper functions defined in stdlib.txt.

Dunno anything about racket except that it's a lisp dialect, as is scheme. Scheme tends to be focused on minimalism. Yeah, I'll push out another small release when 0.24 comes out.

Info about compiling the source into the kerbal dll plugin can be found here: http://wiki.kerbalspaceprogram.com/wiki/Plugins I used monodevelop. Scheme in general doesn't do explicit loops, preferring recursion instead. But I also provide a lot of built-in functions to do things that you might do with a loop in an imperative language; if you're processing a list for example there are functions which run a function on each element and accumulate the result (see map or foldl).

OK, URL updated! http://kerbal.curseforge.com/ksp-mods/222031-automated-guidance-computer

Man, I thought kerbalspaceprogram.com was supposed to stay up. Oh well. I re-uploaded the mod to Curse, I'll bump the thread once it gets approved and goes live. Let me know what you think of the mod.

The source isn't up on github yet, it's still on my TODO list. I'll put it up soon. Right now the source is distributed in the zipfile. If it's a common convention to return nil on no "cond" predicates matching, I'll go ahead and add that. Thanks for the info, I'm not a very experienced lisp programmer, so I'm relying on people like you to tell me this stuff.

Updated to version 0.3! Now with orbit and target parameters, plus a PID controller example. Also, include weissel's bugfix. Still TODO: * allow controlling the AGC with action groups * put the source on github

Ah hah, thanks for the typo fix! The project is still go, in fact I'll release a new version shortly. I'll also get it up on github so people can contribute if they'd like.

Thanks for the encouragement! LISP still has lots of parentheses. But it's a simple, elegant language that (maybe most importantly) is easy for me to write a robust parser and interpreter for. I think it's also pretty easy to understand for someone who doesn't have a ton of programming experience. I do recommend a text editor with syntax highlighting so you can understand the crazy nested parentheses, though.... If anyone wants to donate a better 3d model, or give me permission to use one from another mod, that'd be rad!
