12. History and future of LMPC

LMPC started in the good old DOOM days as a very small Turbo Pascal 6.0 program to show me what's in these LMP files. It is now a ``fat'' C application and has way too many command-line switches. DEMcut is not as widely used as LMPC but it started the DEM editing hype. DBS (I really have to change this name) gave the Keygrip authors ( http://www.planetquake.com/keygrip) the starting point for their internal fake Quake server.

• DEM: Hexen II support (it was always only a small subset) totally removed.

3.2.1 (9/8/1998) (stable release)

• The script to extract the C-Source out of the specs file is included too.
• WWW: upload script uploads now the packages to the right place to deliver them to all http://www.cdrom.com mirrors. In the last release this was totally wrong.

3.2.7 (5/24/1999) (bug fix release)

• Compile: source can be compiled with C++ compilers too. No C++ specific feature used up to now. Many new C++ related warnings corrected.
• General: severe buffer overflow problems corrected. Thanks to Nathan Whitaker ( naif@3dcoder.freeserve.co.uk) for the bug report and a demo file.
• Compile: Linux binaries are glibc finally. I updated my main development system from SuSE Linux 4.2 (about 4 years old) to SuSE Linux 6.1 to do this.

3.3.0 (1/23/2000) (public release)

• DM2: RLA (Quake II Relay) support.
• Docu: Some links updated.

Plan for 4.0.0 in order of importance

1. Block-oriented rewrite of the text parse routines.
2. Object-oriented demo handling. This is really necesary for further recording formats.
3. More code generation out of the XML specs source.
4. Strict separation of the different recording types and the main program. Maybe something like librecord.so.
5. --split-multi option to split multi-level recordings.
6. Half-Life (DEM), Heretic II (DM2) and Sin (DM2) support.
7. DEMcut and DBS with QWD and DM2 support.
8. File-IO from stdin and to stdout, really difficult is the file type detection.
9. Redneck Rampage decompression.

Ideas finally dropped out:

1. Hexen II and HexenWorld support.

Open problems

1. Does someone know the difference between the Redneck Rampage compression algorithm and the one used in Duke Nukem 3D?

A new regular version of LMPC (like 3.3.0) will be announced on BluesNews and on PlanetQuake.

You can download LMPC from my Demo Specs page.

There you will find always the latest release with new features and brand new bugs.
