A general-purpose open-source programming language and compiler designed to provide developers with an elegant and concise development experience, enabling them to build secure and reliable cross-platform software simply and efficiently.

• Lightweight, concise, and consistent syntax design, easy to master and get started quickly
• Strong type system, static analysis and compilation, memory safety, exception handling, making it easy to write secure and reliable software
• Built-in concurrency primitives: go/future/channel/select
• Compiles directly to machine code for the target platform, does not rely on LLVM, and supports cross-compilation.
• Simple deployment, efficient compilation, static linking based on musl libc with good cross-platform characteristics
• Comprehensive type system supporting generics, union types, interfaces, nullable(?), errable(!)
• High-performance GC implementation with very short STW (Stop The World)
• High-performance memory allocator implementation, referencing tcmalloc
• High-performance shared-stack coroutine implementation, capable of millions of coroutine switches per second
• High-performance IO based on libuv implementation
• High-performance runtime and compiler based on pure C implementation
• Built-in data structures vec/map/set/tup and common standard library implementations
• Function calls follow system ABI, built-in libc, convenient for calling C standard library functions
• Centralized package management system npkg
• Editor LSP support

The nature programming language has reached an early usable version, with a basically stable syntax API that will not change significantly before version 1.0. Future versions will add some necessary and commonly used syntax features such as enum, ternary operators, struct labels, etc.

The current version supports compilation for the following target architectures: linux_amd64, linux_arm64, linux_riscv64, darwin_amd64, darwin_arm64. Future versions will leverage zig ld to compile for Windows platforms.

Nature includes a set of test cases and standard libraries to test the usability of basic functionality and syntax, includes a set of small to medium-sized projects to test overall usability, but has not yet been tested in large-scale projects.

Download and extract the nature installer from releases (note the correct permissions). Move the extracted nature folder to /usr/local/ and add the /usr/local/nature/bin directory to the system environment variable.

If you need to install into another directory you need to manually set the NATURE_ROOT environment variable to the corresponding directory

Run the nature -v command to check the version, and run the nature -h command to check the help

> nature -v
nature vx.x.x - release build 1970-01-01

create a main.n file

import fmt   
    
fn main() {   
    fmt.printf('hello nature')
}   

compile and execute

> nature build main.n && ./main   
hello nature

The Nature programming language is a lightweight, simple, and easy-to-learn programming language that references golang in terms of design philosophy and runtime architecture.

Nature focuses on memory safety in its syntax design, has comprehensive type system support and convenient error handling methods, uses files as module units, and adopts a centralized package management approach based on package.toml.

Nature natively supports concurrency primitive go+select+channel, which has excellent concurrency performance in highly concurrent IO applications. Performance will be further improved when the official version is released.

Nature has a completely self-developed compiler, assembler, and linker (which will later transition to zig ld), making Nature more flexible and controllable. The source code is simple without complex third-party dependencies, making it easy to participate in contributions and perform highly customized optimizations according to language and technology development.

Benefiting from simple syntax design, automated memory management, compile-time static analysis and other features, it brings extremely low coding burden, making the Nature programming language very suitable for AI coding and programming beginners.

As a general-purpose programming language, based on existing language features and standard library implementations, Nature can be used in various fields such as web development, command-line programs, databases, network middleware, container systems, IoT devices, programming education, operating systems, game engines and game development.
