Homebrew software

Various homebrew software packages are available, grouped by section into editors, graphics, utilities, modules and java.

Editors

AE - Andys Source Code Folding Editor.

Is a small portable folding editor which runs on a variety of common platforms. Note: All the source code downloadable from here is folded. Now virtual folds can refer to directories, which are listed when entered.

• Binaries for DOS, 32-bit OS/2, Windows, NetWare, Linux (x86, x86_64 and 64-bit big-endian MIPS R3000), AIX (Power), HP-UX, SunOS (Sparc) and Cygwin.

BEBIG - Binary Editor Memory Extension for accessing big files.

Allows BE to edit huge files, by not reading them into memory, and by seeking around an open file instead.

• Documentation.
• Source.

BEDEV - Binary Editor Memory Extension for accessing devices

Allows BE to edit device special files, by seeking, reading and writing.

BEEXEC - Binary Editor Memory Extension for viewing output of programs.

Allows BE to view data which originates from some other script or executable. Provided to help when your only way to get the data is through some other program for which you don't have source. Basically the plug-in keeps shelling out to the program, to ask it for data at a given location, and caches everything it gets back.

• Documentation.
• Source.

BENWMEM - Binary Editor Memory Extension for editing NetWare 4 memory

Allows BE to peek into other modules memory and decode it. (Under NetWare 4, all NLMs etc. share the same address space).

• User documentation.
• Source code.
• Binaries for 32-bit OS/2.
• Binaries for Windows.

GBMOS2PM - Some OS/2 and PM programs using GBM.

These programs used to be a part of the base GBM stuff above, but seeing as they are OS/2 specific, I've seperated them out. Includes GBMV viewer, GBMV2 viewer, GBMVFSA full screen animator and GBMLOGO OS/2 boot logo generator.

• Documentation.
• Source and binaries for 32-bit OS/2.

XGBMV - XWindows GBM Viewer

Simple program to display a bitmap loaded by GBM onto a XWindows TrueColor/DirectColor or PseudoColor visual display. PseudoColor support is via a fixed crude 2x2x2 palette.

• Documentation.
• Source.

MR - Modular Renderer.

C++ class library providing CSG Raytracing, Polygon Rendered and Wireframe graphics capabilities. The raytracing engine supports planes, spheres, cylinders, elliptical cylinders, ellipsoids, cones and general quadratics. It supports reflection, refraction and both 2D and 3D texture maps, which may be linear, cylindrical polar or spherically polar. Includes simple classes for the display of images on XWindows or Windows. Uses GBM to handle image file formats. Cross platform portable to many platforms.

• Documentation.
• Source.
• Gallery.

RTMR - RT Raytracer, implemented using MR

This is an enhancement of my earlier RT raytracer (no longer available), and is implemented using the MR library. It can show the tracing as it happens on XWindows or Windows. Cross platform portable to many platforms.

• Documentation.
• Source.

SHOW - Show image

Very simple program which uses MR to load and show a bitmap on XWindows or Windows.

• Documentation.

LADYBIRD - Ladybird animation

Uses MR to raytrace in real time a picture of a ladybird, from a continually changing viewpoint. Displays the animation on XWindows or Windows. Can be made to write successive frames to files. Cross platform portable to many platforms.

• Documentation.
• Source.

Utilities

FL - File Lister.

Is a variation on UNIX find, implemented using ERE and DIRT.

• Documentation.

Is a variation on UNIX egrep implemented using ERE and DIRT.

• Documentation.
• Source.

LA - Log Accumulator

A simple program which watches multiple logs and produces a single consolidated log.

• Documentation.
• Source.

Modules

TH - Andys Terminal Handler.

Is a code module which provides OS independant access to the text mode screen, as used by AE, BE and other tools.

• Documentation.
• Source supporting DOS, OS/2, Windows, NetWare, AIX, Linux, SunOS, HP-UX and Amiga.

• Documentation.
• Source supporting for DOS, OS/2, Windows, NetWare, AIX, Linux, SunOS and HP-UX.

MPP - Makefile Pre-Processor.

A simple UNIX sh/awk script to allow you to take a makefile suitable for use with GNU make, which uses ifdef directives, and to produce a pre-processed version of the makefile, suitable for use on versions of make with differing or no support for conditional directives. All my UNIX makefiles I supply are GNU make compatible, so if you plan to use them on a system without it, it is well worth downloading this tiny script.

• Script.

Java

Mini-AWT - Minimal plug-in replacement for java.awt.*

Implements rectangle drawing and text writing portions of AWT. For use in environments where AWT not available or operable. Eg: UNIX server not running XWindows.

TrendServer - Serves trend information graphically

Trivial shell script logs CPU and memory utilitisation samples to a file, and TrendServer converts this information to a graphical form, which may be accessed from a web browser. Implemented as TrendServlet, hosted in the nyangau.se servlet engine.

• Documentation (as served by TrendServer).
• Package (including nyangau-miniawt.jar and nyangau-se.jar).

Finding me

As I may change ISP from time to time, you find that this page vanishes in the future. To locate the new location, a search for "Andy+Key+nyangau" in any search engine is pretty much guaranteed to find me and this site.
