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.
./tool build debug tui
# debug build of the terminal ui
# binary placed at build/debug/tui
./tool -c clang-7 build release tui
# build the terminal ui with a compiler named
# clang-7, with optimizations enabled.
# binary placed at build/release/tui
./tool clean
# same as make clean, removes build/
Run
The CLI (orca 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.
orca [-t timesteps] infile
You can also make orca read from stdin:
echo -e "...\na34\n..." | orca /dev/stdin
