A toy OOP language with lexer, parser, compiler and runtime

Not completed yet, and your contributions are highly appreciated

Having learned about the theory of compiler, a dull coder try to develop something to have fun.

XSharp is compiled into the byte codes,and then run in a XSharp runtime environment.

Also it provide a way to generate native binary withLLVM

This project can be built with CMake

Input the command below in to build XSharp Compiler in your computer(Only support Linux now)

# Install LLVM dependencies for XSharpsudo apt install llvm-15# Install toolchain for compiling XSharpsudo apt install build-essentialgit clone git@github.com:XChy/XSharp.git where/xsharp/lies/incd where/xsharp/lies/in./buildRelease.sh

#default compile into a binary executablebin/xsharpc xxx.xsharp#compile into bytecode, not supported yetbin/xsharpc -vm xxx.xsharp# compile into bytecode which can be executed by XSharp's VMbin/xsharp xxx.xe# execute the bytecode

• LLVM (optional)

  XSharp can compile XSharp code into LLVM IR, whichXSharp applyLLVM15(or above) to compile and optimize to generate binary.

• FMT

  For format printing.

• CLI11

  For CLI argument parser.

• Boehm GC (Temporary GC, I may develop a unique one for XSharp later)

  For garbage collection.

• simple OOP

• basic types

• complete type conversion rules

• module

• match pattern

• Variable Declaration

i32 a =2333;

• Function Declaration

i32abs(i32 a){if(a >=0)return aelsereturn -a;}

• Class Declaration

classfoo{    i32getAge()    {return self.age;    }voidsetAge(i32 age)    {        self.age = age;    }    i32 age;}

• HelloWorld

voidmain(){print("Hello,World!");}
