Note
This is an educational programming language implementation. Do not expect anything robust, fast or something you could use in production.
Juls is a programming language plus compiler. The goal of this project is to learn more about programming languages, compilers and other surrounding tools. That means that most parts of the compiler are implemented from scratch and kept very simple.
The compiler is implemented in C99 and dependencies are kept to a minimum to ease porting to different platforms.
Currently the compiler supports generating code and binary files for Aarch64 and x86_64 on Android, Linux and macOS. Windows support is planned.
#import "print";
main :: ()
{
print("Hello World!\n");
}
Juls uses c_make as its build system. The following commands should get you going. For more details see https://github.com/jrng/c_make.
$ cc -o c_make c_make.c # only needs to happen once
$ ./c_make setup build
$ ./c_make build build$ cl -Fec_make.exe c_make.c # only needs to happen once
$ c_make setup build
