ORCΛ
Each letter of the alphabet is an operation, lowercase letters typically operate on bang(*
), uppercase letters operate on each frame. Bangs can be generated by various operations, such as E
colliding with a 0
, see the bang.orca example. Watch a music video of ORCΛ in action.
C Port for the ORCΛ programming environment, with a commandline interpreter.
Prerequisites
Core library: A C99 compiler (no VLAs required), plus enough libc for malloc
, realloc
, free
, memcpy
and memset
.
Command-line interpreter: The above, plus POSIX.
Interactive terminal UI: The above, plus ncurses (or compatible curses library).
Build
The build script is in bash
. It should work with gcc
(including the musl-gcc
wrapper) and clang
, and will automatically detect your compiler.
Currently known to build on macOS (gcc
, clang
) and Linux (gcc
, musl-gcc
, and clang
, optionally with LLD
).
Not yet tested on Windows, but it's likely that it already works under cygwin
. Further testing will be performed soon.
There is a fire-and-forget make
wrapper around the build script.
Make
make debug # debugging build, binary placed at build/debug/orca make release # optimized build, binary placed at build/release/orca make clean # removes build/
Build Script
Run ./tool --help
to see usage info. Examples:
./tool -c clang-7 build release orca # build the terminal ui with a compiler named # clang-7, with optimizations enabled. # binary placed at build/release/orca ./tool build debug cli # debug build of the headless CLI interpreter # binary placed at build/debug/cli ./tool clean # same as make clean, removes build/
Run
Interactive terminal UI
orca [options] [file]
Run the interactive terminal UI, useful for debugging or observing behavior. Pass -h
or --help
to see command-line argument usage.

, and other printable characters: write character to grid at cursor- Spacebar: step the simulation one tick
ctrl+u
: undo/

operator)[

: resize grid vertically
CLI interpreter
The CLI (cli
binary) reads from a file and runs the orca simulation for 1 timestep (default) or a specified number (-t
option) and writes the resulting state of the grid to stdout.
cli [-t timesteps] infile
You can also make cli
read from stdin:
echo -e "...\na34\n..." | cli /dev/stdin
