Trent Apted's Public Code

This site is a collection of code I've developed in my spare time, placed here in case other people find it useful (and also because I'm a compulsive code hoarder and organiser). If you find a bug or have some other suggestion or comment, file a New Ticket (you *must* set a session cooking by clicking Preferences first, or it will probably get rejected as spam).

These mini-projects are organsised by language and summarised here. Follow the links in the summary for more details.

All the projects below are in the source browser, but I haven't had time to write them all up yet -- feel free to explore.

There is also a section of this wiki dedicated to things that are NotCode.

If you're looking for my contact details they're probably on my homepage.

Public SVN Root

http://code.apted.net/svn/pub/

But you probably don't want to check that out, because you will get all the tags and branches -- see the project pages for meaningful checkout examples.

Audio Project on SourceForge

I have an audio project hosted on SourceForge called TappedAudio, released under LGPL. I describe it as "an audio library with an emphasis on the programming interface -- independent of the backend, written in highly-encapsulated C++ and using SWIG to present a unified API for C++, Python, Ruby, etc., regardless of the underlying audio platform". Basically, it bridges the gap between loading sound files and playing or recording them with a very clean cross-platform and cross-language API. See the SourceForge home page or SourceForge project page for more info.

C++

ThreadMan: Synchronised thread manager

See ThreadMan, code. Provides cross-platform management of threads (e.g. "joinAll", automatic cleanup), templating to match threadable functions and a "synchronised" mode that starts threads of the same function in series.

ExactRbn: An elegant implementation of an exact-interpolation RBF Neural Network

See ExactRbn, code. Provides an elegant templatized implementation of an exact-interpolation Radial Basis Function neural network for approximating real-valued vector functions, solved by LAPACK. Includes a demonstration program that "calibrates" 2-dimensional points.

Handle: Thread-safe C++ reference-counting handle using atomic counters

See Handle, code. Provides name demangling and automatic upcasting (throwing BadCast? where needed).

RxString: regular expression string library

See RxString, code.

RConfig: Readable (rconfig) file parser and variable binder

See RConfig: code. See mylib/trunk/configapp for a use-case.

EditLineWrap?: C++ Wrapper around libeditline

See EditLineWrap?. Gives a clean C++ API for libeditline (or libedit, a BSD readline workalike). See mylib/trunk/configapp for a use-case.

Crudebug?: Debugging libraries with runtime stacktrace support

SdlServer?: A cross-platform and thread-safe threaded server built on top of SDL

libFolder?: Cross-platform folder walking and search

ListUtils?: C++ output operators for STL collections (mainly)

libMinXML?: non-validating XML file parser in 250 lines of code

Calibrator?: Coordinate-system calibrator using ExactRbn

chpass?: setuid htpasswd file updater

pirates?: brute force dice rolling probability algorithms

conbn?: C++ templates on steroids for testing Correlation Coefficients for Bayesian Networks

tprintf?: Type-safe templatized printf if you can't wait for C++0x

Raybo: CSG Ray Tracer, specialising in "Logo" blocks

Sample ray tracings: http://zip.phpwebhosting.com/~tapted/tgallery/raybo

C

SockPrintf: a cross-platform printf for TCP and UDP sockets - oh how I love thee

See SockPrintf. Provides a cross-platform tcpprintf and udpprintf that work somewhat like fprintf but accept TCPFILE* or a hostname(!) as a char* as the first argument.

Allocator?: Macros for creating *very* efficient allocators for small objects >= sizeof(void*)

Shuff?: A (slightly faster) implementation of /usr/bin/shuf, done before it appeared in GNU coreutils

forkopen?: Like popen, but use fork and execl so we don't execute a shell

chrooter?: setuid C program to auto bind mount paths and allow users to chroot

picksquare?: OpenGL app for testing performance of glRenderMode(GL_SELECT)

Python

PyBib?: AJAX CGI Scripts to search and manage BibTeX databases

Java

bib2endnote?: My BibTeX to Endnote converter

MIPS Assembler

MIPSBI?: Arbitrary-length integer library in assembly code

Matlab

random assignments

Prolog

Haskell

C/C++ Undergrad Projects

I make no guarantees about the code quality of these -- I was still learning!

(C++) Backpropagation Neural Network

(C++) Reinforcement-learning Blackjack Program

(C) debugging C interpreter, written in C

(C) QUERY_STRING parser

uunique

sulley

madman

lambda

Various

AutoTemplate?: Templates for autoconf/automake projects
