This is the repository for the Kyoto Programming Language and its compiler, Cyoto. Kyoto is a statically typed, compiled language that is still in early design stages. The compiler is written in C++ and utilizes LLVM for analysis and code generation.
Cyoto requires the following dependencies:
- LLVM >= 20
- CMake >= 3.20
- Java >= 8
- antlr == 4.13.2
- Boost >= 1.74.0
- GCC >= 13 (for C++23 and std::fmt support)
To install the dependencies on Ubuntu, run the following commands:
$ sudo apt-get install llvm-20-dev cmake default-jre libboost-all-dev gcc-13 g++-13 libfmt-dev libzstd-devAntlr 4.13.2 can be installed from the official website's mirror as follows:
$ wget https://www.antlr.org/download/antlr-4.13.2-complete.jar -O /path/to/install
$ chmod +x /path/to/install/antlr-4.13.2-complete.jar
$ export PATH="/path/to/install:$PATH"If llvm-20 is not available in the package manager, it can be installed using the script provided on the official website as follows:
$ wget https://apt.llvm.org/llvm.sh
$ chmod +x llvm.sh
$ sudo ./llvm.sh 20 allTo build the compiler, run the following commands:
$ mkdir build
$ cd build
$ cmake .. -DCMAKE_CXX_COMPILER=g++-13 -DCMAKE_C_COMPILER=gcc-13
$ make cyoto -j$(nproc)To run the tests, you can use the following command:
$ make ktest -j$(nproc) && ./ktestTo compile a Kyoto source file, run the following command:
$ ./cyoto --help
Usage: ./cyoto [OPTIONS] INPUT_FILE
The Kyoto Programming Language Compiler:
-h [ --help ] Print this help message
-r [ --run ] Run the program in `lli` after compilation
-o [ --output ] arg (=a.out) Output file for the executable binaryThis repository includes a grammar-based fuzzer for the Cyoto compiler, which is based on the ANTLR4 grammar for Kyoto defined in kyoto/grammar/.
The fuzzer is written in Rust. For more information on how to use it, refer to the README in the fuzzer directory.
