Corewar

About

Core War is a 1984 programming game created by D. G. Jones and A. K. Dewdney in which two or more battle programs (called "warriors") compete for control of a virtual computer. These battle programs are written in an abstract assembly language called Redcode.

Here's how it looks like:

We don't use the same set of assembly instructions as the original Corewar and we have some modulo limitations for the read and write ranges.

How to use it ?

• First you'll need to write a .s file with a set of assembly instructions
  • You can find this set in either corewar.pdf or in corewar_en.pdf
  • Or you can just use one of the many warriors in the resources/champions directory
• Then you'll have to compile it using the asm binary
• Then just execute the corewar binary with your warrior(s) as arguments

This was the final project of the Algorithm branch.

Installation

Just run make -C Corewar fclean && make -C Corewar... enjoy!

Work on OS X El Capitan and macOS Sierra, the ncurse library is used for the viewer.

Usage

Binaries

corewar

./corewar [-d N -s N -v N | -b --stealth | -n --stealth] [-a] <champion1.cor> <...>

• -a : Prints output from "aff" (Default is to hide it)
• -d N : Dumps memory after N cycles then exits
• -s N : Runs N cycles, dumps memory, pauses, then repeat
• -v N : Verbosity levels, can be added together to enable several
• • 0 : Show only essentials
• • 1 : Show lives
• • 2 : Show cycles
• • 4 : Show operations (Params are NOT litteral ...)
• • 8 : Show deaths
• • 16 : Show PC movements (Except for jumps)
• -i : Ncurses output mode

asm

./asm [-d champion.cor] | champion.s

• -d : Reverse compiler
  • Generate an assembly file from a corewar file (.cor)
  • (Comments are lost as well as label)
  • (Default is to generate a corewar file from an assembly file)

Scripts

check_asm

./check_asm.sh [-del] [-exec] [-diff] [-deasm]

• -del : Delete created files
• -exec : Execute the script
• -diff : Execute diff on all compiled files
• -deasm : Execute the reverse compiler option then execute diff

script_v

./script_v [number of champ 1-4] <champ name> <...>

• champ name are given without the .cor extension
• champ have to be placed in the folder resources/champions
