Cyclang
A programming language I built in Rust - mainly for fun and my own learning! Uses PEG Parser in Rust for parsing and LLVM (llvm-sys) as the backend to compile to machine code binary. Check the user guide for a detailed overview of the language.
Try the Fibonacci example in /examples/fib.cyc
fn fib(i32 n) -> i32 {
if (n < 2) {
return n;
}
return fib(n - 1) + fib(n - 2);
}
print(fib(20));
You will need Rust installed to run the below command.
cyclang --file ./examples/fib.cyc
This should output 6765
!
Installing and Running
You will need LLVM 17 installed before you install cyclang,
For MacOS run the following command
brew install llvm@17
For Ubuntu install the following packages
llvm-17
llvm-17-tools
llvm-17-dev
clang-17
libpolly-17-dev
And run make set-llvm-sys-ffi-workaround
Then the easiest way to install the binary currently is through the Rust package manager Cargo - see Install Rust. Once the step above is done, then run
cargo install cyclang
See the book for a more detailed guide on setup.
