phicode 2.2.0

(φ) PHICODE Engine — run φ code directly in Python/PyPy with optional Rust acceleration

PHICODE Runtime Engine

🚀 Mathematical Programming Made Executable - Transform intuitive mathematical notation like ∀, λ, ⇒ into native Python code with zero performance overhead

Target Audience: Python developers, researchers, mathematicians, and data scientists who prefer mathematical notation over verbose keywords. Ideal for academic computing, symbolic programming, and projects requiring mathematical expressiveness.

⚠️ Development Status: Production-ready with active feature development.

🎯 Executive Summary

PHICODE enables writing Python using mathematical symbols through a sophisticated meta path finder and bytecode caching system. Files with .φ extension are automatically translated to standard Python and compiled with full optimization. The system provides thread-safe operations, persistent caching, and zero-overhead execution after initial compilation.

Value Proposition: Reduce cognitive load by writing code that matches mathematical thinking patterns while maintaining full Python ecosystem compatibility and performance.

🔍 Diagnostics & Troubleshooting

🚨 Common Error Scenarios & Solutions

⚠️ Import and Module Errors

Error Code 2: Source Folder Not Found

# Symptoms: "PHICODE source folder not found: /path"
# Cause: Invalid file path or missing directory
# Solution:
ls -la $(dirname your_file.φ)  # Verify file exists
phicode $(pwd)/your_file.φ     # Use absolute path

Error Code 3: Module Import Failure

# Symptoms: "Error running module 'name': ModuleNotFoundError"
# Cause: Missing dependencies or syntax errors in .φ file
# Solution:
python -c "import ast; ast.parse(open('file.φ').read())"  # Check syntax
pip install missing-dependency  # Install dependencies

ImportError: phicode_engine not found

# Symptoms: Cannot import phicode_engine modules
# Cause: Installation incomplete or virtual environment issues
# Solution:
pip uninstall phicode && pip install phicode  # Reinstall
python -c "import sys; print(sys.path)"       # Check Python path

💾 Cache and Performance Issues

Cache Corruption or Stale Data

# Symptoms: Old code executing despite file changes
# Cause: Cache invalidation failure or filesystem timestamp issues
# Solution:
rm -rf .phicode_cache/                    # Nuclear cache reset
find . -name "*.pyc" -delete             # Clear Python bytecode
touch your_file.φ && phicode your_file.φ # Force recompilation

High Memory Usage

# Symptoms: Python process consuming excessive memory
# Cause: Large cache size or memory leak
# Solution:
from phicode_engine.core.phicode_cache import _cache
print(f"Cache entries: {len(_cache.source_cache)}")  # Check cache size
# Restart process or reduce MAX_CACHE_SIZE

Slow Performance on Network Filesystems

# Symptoms: Slow startup on NFS/SMB mounted directories
# Cause: Network latency affecting file operations
# Solution:
export PHICODE_CACHE_DIR="/local/fast/cache"  # Use local storage
rsync -av /network/project/ /local/project/   # Work locally

🔤 Unicode and Encoding Problems

UnicodeDecodeError on Symbol Files

# Symptoms: "UnicodeDecodeError: 'utf-8' codec can't decode"
# Cause: File encoding mismatch or terminal configuration
# Solution:
file your_file.φ                          # Check file encoding
iconv -f ISO-8859-1 -t UTF-8 file.φ      # Convert encoding
export PYTHONIOENCODING=utf-8            # Force UTF-8 mode

Symbols Not Displaying Correctly

# Symptoms: � or missing characters in terminal
# Cause: Terminal font lacks mathematical Unicode support
# Solution:
# Install a Unicode-complete font (Fira Code, JetBrains Mono)
echo $LANG                                # Verify locale settings
locale -a | grep -i utf                   # Check UTF-8 availability
