文言 wenyan-lang | LLVM Compiler

A compiler for wenyan-lang that generates LLVM IR code.
This project allows wenyan-lang to be compiled to modern platforms.

Overview

Wenyan-LLVM compile wenyan-lang code into LLVM IR.
This allows Wenyan code to leverage LLVM’s optimization capabilities and target multiple architectures.

This compiler uses Flex for lexical analysis and Bison (compatible with Yacc) for parsing, provides easy maintenance and contributions for developers.

This project follows the grammar of wenyan-lang, see wenyan-lang and wenyan-book

Features

• More intuitive error messages
• More standardized syntax
• Chinese Numeral System
• LLVM Backend

Example

A simple Wenyan program that prints a message twice and then counts from 1 to 10:

為是 二 遍。
    吾有一言。曰「「問天地好在。」」。書之。
云云。

吾有一言。曰「「開始數數」」。書之。
有數 零 。名之曰「甲」。

為是 十 遍。
    加一以「甲」。昔之「甲」者。今其是矣。

    吾有一言。曰「甲」。書之。
云云。

吾有一言。曰「「數完了」」。書之。

This compiles to LLVM IR with string constants and loops properly implemented.

Building

This project requires:

• CMake
• Flex and Bison (3.0 or higher)
• LLVM development libraries (llvm clang)

# Clone the repository with submodules
git clone --recursive https://github.com/WavJaby/wenyan-llvm.git

# Install requirements
apt install flex bison

# Create build directory
mkdir build && cd build

# Configure and build
cmake ..
make

Usage

# Compile a Wenyan source file to LLVM IR
./main input.wy output.ll

# Install llvm requirements
sudo apt install llvm clang

# If you want to directly execute LLVM IR code
# lli output.ll

# Compile llvm
llc -filetype=obj -relocation-model=pic output.ll
clang -fPIE output.o -o program

# Run final program
./program
