Spherehorn is an esolang (esoteric programming language) that I created. It's named after the Alexander horned sphere, due to a passing resemblance between the horned sphere construction and the 'circular tree' data structure that Spherehorn uses for code and memory.
This repository is an interpreter for Spherehorn. For a short guide to the language, see guide.md. There are various example programs in the examples/ directory.
You'll need g++, or a compatible compiler, to compile Spherehorn. If you don't
have a C++ compiler, install g++ using your package manager of choice; with APT,
running sudo apt update && sudo apt install g++ works nicely.
Once you've cloned/downloaded this repository, navigate to its root directory
(where build.sh is) in your terminal emulator and run the build script with
sh build.sh. When it's done executing, you'll find a new file, spherehorn,
in the directory. Try running
echo "3 5 50" | ./spherehorn examples/fizzbuzz.spherehorn and see what
happens.
If you're using a non-g++ compiler, switch out the line compiler=g++ in
build.sh for your compiler. The new compiler must be compatible with g++'s
command line options; clang should work, but I haven't tested it.
If you don't have the Bourne shell (sh) installed, the build script should
also work with bash, ksh, and zsh.
The repository includes a makefile if you'd like to use make. It was written for
GNU make, so it may not work correctly with your dialect. You can change the
line CXX := g++ if you want to use a different compiler; you may also need to
change the compiler flag variables.
Compile together all the .cpp files in the src/ directory. The project uses
the C++20 standard.
