🚀 Quick Start

Installation

After publication (coming soon):

# Install from crates.io
cargo install portalis

# Verify installation
portalis --version

Current (development):

# Clone and build from source
git clone https://github.com/portalis/portalis.git
cd portalis
cargo build --release --bin portalis

# Run CLI
./target/release/portalis --version

Basic Usage

Zero-friction conversion - Navigate and convert:

# Navigate to your Python project
cd my-python-project/

# Convert to WASM (defaults to current directory)
portalis convert

Or convert specific files/packages:

# Convert a single script
portalis convert calculator.py

# Convert a Python library (creates Rust crate + WASM)
portalis convert ./mylib/

# Convert a directory of scripts
portalis convert ./src/

Auto-detection handles:

• ✅ Single Python scripts → WASM
• ✅ Python packages (has __init__.py) → Rust crate + WASM library
• ✅ Directories with Python files → Multiple WASM outputs
• ✅ Entire projects → Complete conversion

See QUICK_START.md for detailed examples and USE_CASES.md for real-world scenarios.

🧬 NVIDIA AI Workflow

1. Code Analysis (CUDA Accelerated)

# Traditional approach: 10,000 files = 30 minutes
# PORTALIS + CUDA: 10,000 files = 2 minutes (15x faster)

# Parallel AST parsing across GPU cores
cuda_engine.parallel_parse(python_files)

# GPU-accelerated embedding generation
embeddings = triton_client.infer(
    model="code_embeddings",
    inputs={"source_code": code_batches}
)

2. AI-Powered Translation (NeMo)

# NeMo-based translation with context awareness
translation = nemo_client.translate(
    source_code=python_code,
    context={
        "stdlib_usage": ["pathlib", "json", "asyncio"],
        "frameworks": ["fastapi", "pydantic"],
        "style": "idiomatic_rust"
    }
)

# Confidence scoring and alternative suggestions
if translation.confidence < 0.8:
    alternatives = nemo_client.generate_alternatives(
        python_code, num_candidates=3
    )

3. Deployment (Triton + NIM)

# Triton model configuration
name: "portalis_translator"
platform: "python"
max_batch_size: 64
instance_group: [
  { count: 4, kind: KIND_GPU }  # 4 A100 GPUs
]
dynamic_batching: {
  preferred_batch_size: [16, 32, 64]
  max_queue_delay_microseconds: 100
}

4. Validation (Omniverse)

# Load WASM into Omniverse simulation
omni_bridge.load_wasm_module(
    wasm_path="translated_app.wasm",
    scene="validation_scene.usd"
)

# Run side-by-side comparison
python_results = run_python_simulation()
wasm_results = omni_bridge.execute_wasm_simulation()

# Visual validation
omni_bridge.compare_outputs(python_results, wasm_results)
