Vein is an open source experimental high-level strictly-typed programming language with a standalone OS, arm and quantum computing support.

OS Support

Compiling from source

Building on Windows

For building, you need the following tools:

• dotnet 6.0
• Win10 SDK
• vsbuild-tools-2019 with MSVC 2019, MSVC142 for ARM64

Checkout vein sources

git clone https://github.com/vein-lang/vein.git --recurse-submodules
cd ./vein-lang
git fetch --prune --unshallow --tags

dotnet restore

Compile IshtarVM

Go to ishtar folder

cd ./runtime/ishtar.vm

Compile for Windows 10 x64

dotnet publish -r win10-x64 -c Release

Compile for Windows 10 ARM64

dotnet publish -r win-arm64 -c Release

Copy output files

mkdir output
cp -R ./runtime/ishtar.vm/bin/net6.0/win10-x64/native/ ./output

The output folder should contain:

• ishtar.exe - main ishtar file
• ishtar.exp - export metadata for main module
• ishtar.lib - dynamic library for main module
• ishtar.pdb - debug symbols

Compile veinc

Go to vein compiler folder

cd .\compiler

Compile

dotnet publish -r win-x64 -c Release

Copy the output files

mkdir output
cp -R ./bin/Release/net6.0/win-x64/publish ./output

The output folder should contain:

• veinc.exe - main executable compiler file

Building on Linux (on ubuntu)

For building, you need the following tools:

• dotnet 6.0
• clang
• zlib1g-dev
• libkrb5-dev
• libssl-dev

and additional for arm64 (or maybe using prebuiled docker image)

• clang-9
• binutils-arm-linux-gnueabi
• binutils-aarch64-linux-gnu
• crossbuild-essential-arm64
• gcc-multilib
• qemu
• qemu-user-static
• binfmt-support
• debootstrap

Checkout mana sources

git clone https://github.com/vein-lang/vein.git --recurse-submodules
cd ./vein-lang
git fetch --prune --unshallow --tags

dotnet restore

Compile IshtarVM

Go to ishtar folder

cd ./runtime/ishtar.vm

Compile for Linux x64

dotnet publish -r linux-x64 -c Release

Compile for Linux ARM64

cd ./cross
sudo ./build-rootfs.sh arm64
cd ..
cd ./runtime/ishtar.vm
dotnet publish -r linux-arm64 -c Release -p:CppCompilerAndLinker=clang-9 -p:SysRoot=/home/.tools/rootfs/arm64

Copy output files

mkdir output
cp -R ./runtime/ishtar.vm/bin/Release/net6.0/linux-x64/native ./output

Compile veinc

Go to vein compiler folder

cd ./compiler

Compile

dotnet publish -r linux-x64 -c Release

Copy output files

mkdir output
cp -R ./bin/Release/net6.0/linux-x64/publish ./output

The output folder should contain:

• veinc - main executable compiler file

Contributing

We welcome everyone to contribute to vein language. To do so, you need to know a couple of things about the folder structure::

/runtime: folder contains all backend vm\generator for vein
  /common: shared code
  /ishtar.base: base abstraction for generator\vm
  /ishtar.generator: logic of IL generator for IshtarVM
  /ishtar.vm: implementation of ishtar vm in C#
/compiler: folder contains source for vein compiler
/lib: folder with common libraries
  /ast: mana AST library, for parsing
  /projectsystem: project system models, for compiler
/lsp: language server for vein lang
/samples: Wow! its samples!
/test: folder with various tests

You can run all tests from the root directory with dotnet test.

To recompile the vm and the compiler: dotnet build.

To recompile the standard library: veinc ./vein.std/corlib.vproj.

After your changes are done, please remember to run dotnet format to guarantee all files are properly formatted and then run the full suite with dotnet test.

Q\A

Q:
  Why it based on C#?
A:
  Initially, i started developing a virtual machine in C++,
  but there were a lot of difficulties with basic things (such as collections, text formatting, etc.)
  And at some point i saw that microsoft began to develop a fully AOT compiler for dotnet.
  That means we could write in pure C# without using runtime and std, 
  which allows everyone to write such hard things like an OS!
  So I decided - that's it! I'm Definitely writing a virtual machine in C#!

  So, now I'm developing using the C# runtime and the std, but 
  in version 2.0 I'm planning to completely move away from runtime dependencies.

Q:
  This language really support quantum computing?
A:
  Not now, but in future I'm planning to add support for Microsoft Quantum Simulator, 
  next - support for Azure Qunatum or IBM quantum cloud.
  And after the release of stationary quantum extension card (like PCEx128 😃), 
  I'll add support for them too.

Special Thanks
