Weasel Language

Weasel Language named after name of animal https://en.wikipedia.org/wiki/Weasel

BACKGROUND

Weasel language is a project i created to prove of concept that we can support heterogenous internally inside a language. We can use GPGPU Computing directly supported by the language. Which mean you just directly code to the language and just works.

And we can create computationally task easyly solved. Like Machine Learning and even AI, because you can switch which program or code need to run on GPU or CPU or any compute hardware without hassle.

We also can binding the library created by weasel language into another languages like python to create better environment for end user to create fast program.

SETUP (see LLVM Documentation)

• Add LLVM Project
• Before build change linker to llvm lld then Build LLVM Project
• Set LLVM DIR
• Build Project

Installing Weasel Language

Linux Version

• Untuk pengguna linux anda dapat menggunakannya pre-release version di github https://github.com/zy0709/underrated_project/releases. Ikuti instruksinya dan langsung gunakan atau ikuti instruksi untuk menginstall dari source code.

Windows Version

• No binary release for windows, follow installing from source code.

Mac OS X

• no binary release for mac os x, follow installing from source code.

Install from Source Code

1. Install Clang

Untuk linux

• anda tinggal run
• sudo apt update
• sudo apt install clang-12

Untuk Windows

• Download clang di https://releases.llvm.org/download.html pilih versi 11.0.0
• Extract dan tambahkan ke variable environment

Untuk Mac OS X

• Clang merupakan default compiler di Mac OS X, jadi tidak perlu menginstall lagi

2. Clone Project

• Tinggal clone project git clone https://github.com/zy0709/underrated_project ke folder project anda

3. Set LLVM DIR

Untuk Linux

• Tidak perlu diganti

Untuk Windows

• Buka file CMakeLists.txt
• Ganti pathnya LLVM_DIR ke {folder clang}/lib/cmake/llvm

Untuk Mac OS X

-Set ke folder cmake llvm (not tested, limited hardware resource)

4. Set Library LLVM SPIRV

Untuk Linux

• Membuat folder third-party
• Download llvm-spirv-11 di https://github.com/zy0709/underrated_project/releases
• Extract lib dan include di file llvm-spirv-11 ke third-party

Untuk Windows

• Build dari source code, ikuti petunjuk dari github aslinya di https://github.com/KhronosGroup/SPIRV-LLVM-Translator
• Lalu pindah libLLVMSPIRVLib.a ke folder third-party/lib
• Dan copy semua file dari include ke third-party/include

Untuk Mac OS X

• Build dari source code, ikuti petunjuk dari github aslinya di https://github.com/KhronosGroup/SPIRV-LLVM-Translator
• Lalu pindah libLLVMSPIRVLib.a ke folder third-party/lib
• Dan copy semua file dari include ke third-party/include

5. Build Source

Untuk Linux

• mkdir build
• cd build
• cmake ..
• cmake --build .
• tunggu process selesai dan anda bisa menggunakan file executablenya

Untuk Windows

• mkdir build
• cd build
• cmake ..
• cmake --build .
• tunggu process selesai dan anda bisa menggunakan file executablenya

Untuk Mac OS X

• mkdir build
• cd build
• cmake ..
• cmake --build .
• tunggu process selesai dan anda bisa menggunakan file executablenya
