Architecture

x86_64, ARM64 (Apple Silicon & Graviton)

🧠 How It Works

moose coordinates its core functionality through a modular C++ pipeline. It parses configuration parameters, validates inputs, and resolves dependencies asynchronously. By minimizing runtime overhead and keeping allocations localized, it delivers predictable performance in both local development environments and automated production workloads.

🎯 Production Use Cases

Production System Integration

Embed moose into C++ backend services to handle core application logic.

CI/CD Automated Pipelines

Run automated validation, builds, and integration suites during deployments.

Developer Tooling & Workflows

Accelerate developer onboarding with pre-configured project utilities.

Open Source Extension

Fork and customize internal modules under the repository's open LGPL-2.1 license.

🚀 Getting Started

1

Install moose using your package manager: `git clone https://github.com/idaholab/moose.git`

2

Initialize your project workspace or configuration file for moose.

3

Import moose into your codebase or invoke it directly from your terminal.

4

Execute your test suite or run `moose --help` to verify successful setup.
