Getting Started with NextViper

Install NextViper, configure your development environment, and build your first application.

Getting Started with NextViper

NextViper is a modern, high-performance programming language designed from the ground up for developer ergonomics, speed, and seamless integration across general software development, data science, and artificial intelligence.

1. Installation

Quick Install (Linux / macOS / Termux)

bash

curl -fsSL https://nextviper.nuratix.com/install.sh | bash

Verify the installation:

bash

nextviper --version
# NextViper compiler v0.1.0 (Vipera Genesis)

2. Your First Program

Create a new project using the NextViper package manager:

bash

nextviper init hello_world
cd hello_world

This generates the standard project directory layout:

code

hello_world/
├── nextviper.toml      # Project manifest & metadata
├── nextviper.lock      # Deterministic SHA-256 lockfile
└── src/
    └── main.nv         # Application entry point

Open src/main.nv and write:

nextviper

fn main() {
    let message = "Hello from NextViper!"
    print(message)

    // Pipeline operator example
    let numbers = [1, 2, 3, 4, 5]
    let squared = numbers 
        |> map(fn(x) => x * x) 
        |> filter(fn(x) => x > 5)

    print("Squared and filtered:", squared)
}

Run your program:

bash

nextviper run src/main.nv

Compile to native binary executable:

bash

nextviper build src/main.nv -o hello_world
./hello_world
