llgo is an advanced Go compiler built on LLVM, designed to seamlessly integrate Go with the C ecosystem, including Python. As a subproject of the Go+ project, llgo opens up new horizons for developers in various fields, such as game development, AI and data science, WebAssembly, and embedded systems.

Key Features

• Enhanced Compatibility: llgo leverages Go's syntax (source code) and the Application Binary Interface (ABI) to offer compatibility with both C and Python, enabling versatile application development.

• C/C++ Standard Library Support: Easily import and use C/C++ libraries in your Go code, including:

  • c
  • c/math
  • c/os
  • More comprehensive libraries available through the project.

Example - C Integration

Here's how you can call a C function within your Go code:

package main

import "github.com/goplus/llgo/c"

func main() {
    c.Printf(c.Str("Hello world\n"))
}

This code demonstrates using C's printf function to print Hello world. The c.Str is a built-in llgo instruction that converts Go strings to C string constants.

Python Integration

llgo allows you to import Python libraries seamlessly through the llpyg tool. Currently supported libraries include:

• py/math
• py/numpy
• py/pandas

Here’s a sample demonstrating Python library usage in Go:

package main

import (
    "github.com/goplus/llgo/py"
    "github.com/goplus/llgo/py/math"
    "github.com/goplus/llgo/py/std"
)

func main() {
    x := math.Sqrt(py.Float(2))       // x = sqrt(2)
    std.Print(py.Str("sqrt(2) ="), x) // Output: sqrt(2) = 1.414...
}

This integrates Python's math.sqrt functionality with Go syntax, providing a powerful combination for developers.

Versatile Library Support

llgo supports various libraries from C and C++ ecosystems, expanding your development possibilities. You can explore libraries such as c/sqlite or cpp/llvm.

Complete Go Syntax Support

All standard Go syntax is supported except for cgo. This ensures developers can utilize familiar constructs without cumbersome workarounds. Some features include:

• Goroutines
• Deferred function calls
• Error handling

Efficient Garbage Collection

LLGo implements garbage collection using bdwgc (libgc), with an option to disable it by specifying the nogc tag if desired.

As an open-source project, llgo stands at the intersection of Go and the C/Python ecosystems, offering developers an unprecedented level of flexibility and power in application development. Whether you're building cutting-edge AI solutions, games, or embedded systems, llgo enriches your development journey with limitless possibilities.
