Important
There's a more in-depth guide on getting started at https://occultlang.org/getting-started
Language specification is at https://occultlang.org/language-specifications
Occult is a systems programming language, meant to give the user the full control and power of a C-like language, but with a modern syntax with modern features, making it easy to write, read and learn.
fn write(i64, string, i64) shellcode i64 { 0x55 0x48 0x89 0xe5 0x48 0xc7 0xc0 0x01 0x00 0x00 0x00 0x0f 0x05 0x48 0x31 0xc0 0x48 0x89 0xec 0x5d 0xc3 }
fn strlen(string) shellcode i64 { 0x55 0x48 0x89 0xe5 0x48 0x31 0xc0 0x80 0x3c 0x07 0x00 0x74 0x05 0x48 0xff 0xc0 0xeb 0xf5 0x48 0x89 0xec 0x5d 0xc3 }
fn puts(string s) {
write(1, s, strlen(s));
}
fn main() {
puts("1\n");
puts("2\n");
puts("3\n");
puts("4\n");
puts("5\n");
}
This is an example of using raw x86_64 shellcode with the Linux write syscall to print out 1 to 5!
Note
The highest C++ standard that Occult should use is C++23
Also, the only architecture Occult supports is amd64 as of now, obviously this will change!
git clone https://github.com/occultlang/occult.git && cd occult
chmod +x build.sh
./build.shBuilding for Visual Studio on Windows (You must install LLVM with clang inside Visual Studio Installer)
git clone https://github.com/occultlang/occult.git && cd occult
cmake -G "<YOUR VISUAL STUDIO VERSION>"
# i.e "Visual Studio 18 2026" for V.S 2026
# running cmake -G should just give you options to choose fromChange the C++ Language Standard to the latest version
Change the Platform Toolset to LLVM(clang-cl) (Or else Occult WILL NOT compile on Windows because of MSVC...)
Next, go into C/C++ -> Command Line, and then remove all the contents of the "Additional Options" field
Afterwards, you should be good to go
