This file is a merged representation of a subset of the codebase, containing files not matching ignore patterns, combined into a single document by Repomix.

================================================================
File Summary
================================================================

Purpose:
--------
This file contains a packed representation of the entire repository's contents.
It is designed to be easily consumable by AI systems for analysis, code review,
or other automated processes.

File Format:
------------
The content is organized as follows:
1. This summary section
2. Repository information
3. Directory structure
4. Multiple file entries, each consisting of:
  a. A separator line (================)
  b. The file path (File: path/to/file)
  c. Another separator line
  d. The full contents of the file
  e. A blank line

Usage Guidelines:
-----------------
- This file should be treated as read-only. Any changes should be made to the
  original repository files, not this packed version.
- When processing this file, use the file path to distinguish
  between different files in the repository.
- Be aware that this file may contain sensitive information. Handle it with
  the same level of security as you would the original repository.

Notes:
------
- Some files may have been excluded based on .gitignore rules and Repomix's configuration
- Binary files are not included in this packed representation. Please refer to the Repository Structure section for a complete list of file paths, including binary files
- Files matching these patterns are excluded: .specstory, examples, *.lock
- Files matching patterns in .gitignore are excluded
- Files matching default ignore patterns are excluded

# Expected Output Files

This directory contains expected output files for testing Phiton conversion.

## File Naming Convention

Files are named according to the following convention:

- `{source_file_name}_level{compression_level}.phi`

For example:
- `simple_level1.phi`: Expected output for `simple.py` with compression level 1
- `simple_level5.phi`: Expected output for `simple.py` with compression level 5

## Adding New Expected Files

When adding new test cases:

1. Create a Python file in the parent directory
2. Run Phiton conversion on the file with the desired compression level
3. Save the output to this directory with the appropriate naming convention
4. Update the tests to use the new expected output file

## Updating Expected Files

If the Phiton conversion algorithm changes, the expected output files may need to be updated. To update them:

1. Run Phiton conversion on the source files with the desired compression levels
2. Compare the output with the existing expected files
3. Update the expected files if the changes are intentional

# Phiton Tests

This directory contains tests for the Phiton package.

## Test Structure

- `conftest.py`: Contains pytest fixtures and configuration
- `test_*.py`: Test files for different modules
- `data/`: Contains test data files
  - `simple.py`: A simple Python file for testing basic functionality
  - `complex.py`: A more complex Python file for testing advanced features
  - `patterns.py`: A Python file with common patterns for testing pattern recognition
  - `expected/`: Contains expected output files for comparison

## Running Tests

To run the tests, you need to install the test dependencies:

```bash
pip install -r tests/requirements.txt
```

Then, from the project root directory, run:

```bash
pytest
```

To run tests with coverage:

```bash
pytest --cov=phiton
```

To run a specific test file:

```bash
pytest tests/test_converter.py
```

To run a specific test function:

```bash
pytest tests/test_converter.py::test_compress_simple_level1
```

## Adding New Tests

When adding new tests:

1. Add test data files to the `data/` directory
2. Add expected output files to the `data/expected/` directory
3. Create test functions in the appropriate test file
4. Use fixtures from `conftest.py` where possible

## Test Coverage

The tests aim to cover:

- Configuration options
- Compression functionality
- Utility functions
- CLI commands
- Error handling

# Phiton Refactoring Progress

## Completed Tasks

1. ✅ Refactored the monolithic `phiton.py` into a proper module structure:
   - `__init__.py`: Main package entry point with public API
   - `config.py`: Configuration dataclass
   - `constants.py`: Symbol mappings and pattern replacements
   - `converter.py`: Core conversion functionality
   - `utils.py`: Utility functions for optimization
   - `cli.py`: Command-line interface
   - `__main__.py`: Entry point for running as a module

2. ✅ Created a proper configuration system:
   - Added `ConversionConfig` dataclass with options for:
     - Compression level (1-5)
     - Comments preservation
     - Type hints preservation
     - Minification
     - Symbol substitution

3. ✅ Improved the compression algorithm:

   - Added `example.py` for testing compression

7. ✅ Improved project structure and organization:
   - Reorganized files into proper directories (src, tests, examples)
   - Updated dependency management in pyproject.toml
   - Added comprehensive dev, test, and all extras
   - Fixed namespace package issues in tests
   - Removed redundant configuration files

## Next Steps

1. Fix linting issues identified by ruff:
   - Fix shebang issues
   - Update deprecated typing imports
   - Fix boolean-typed positional arguments
   - Refactor complex functions
   - Fix exception handling

2. Fix test failures:
   - Update expected outputs to match current implementation
   - Fix configuration level validation
   - Ensure compression levels produce expected results

3. Implement decompression functionality (Phiton to Python)

4. Add support for more complex patterns

5. Add support for custom pattern definitions

6. Create a web interface for online conversion

## Performance Metrics

The refactored code achieves impressive compression ratios:
- Simple functions: ~60-66x compression
- Complex classes: ~63-64x compression

The compression is adjustable with 5 different levels, allowing users to balance between readability and maximum compression.

# Phiton

Phiton is a Python code compressor that converts standard Python code into a more concise notation using mathematical symbols and some lightweight compression techniques. 

Phiton compresses Python into Unicode symbols. Control flow symbols (⇐ for return, ↥ for yield, ⟳ for while, ∀ for for, ⋔ for if, ⋮ for else, ⊘ for pass, ⊠ for break, ⋯ for continue), operators (≔ for =, ≡ for ==, ≠ for !=, ∈ for in, ∉ for not in, ∧ for and, ∨ for or, ¬ for not, ≤ for <=, ≥ for >=), special values (∅ for None, ⊤ for True, ⊥ for False), function definitions (ƒ for def, λ for lambda, Σ for class, ⊡ for async/await), block structure (⟨...⟩ for indented blocks, → for statement separator), common functions (ℓ for len, ℜ for range, ℯ for enumerate, φ for filter, ℤ for zip, ς for sorted, ℛ for reversed), domain prefixes (№ for numpy, ℗ for pandas, χ for sklearn, μ for matplotlib, Ψ for torch, Φ for tensorflow), and literals (#123 for numbers, $text for strings).

---

```bash
echo "#python"; cat test.py; echo; echo "#phiton"; cat test.py | python -m phiton; echo; echo; echo "#re-python"; cat test.py | python -m phiton | python -m phiton -d;
```

```python
def factorial(n):
    if n <= 1:
        return 1
    else:
        return n * factorial(n - 1)
```

Can be phitonized (compressed) to:

```
ƒfactorialn⟨⋔n≤#1⟨⇐#1⟩⋮⇐n*factorialn-#1⟩
```

and then dephitonized (decompressed) to: 

```python
def factorial(n):
    if n <= 1:
        return 1
    else:
        return n * factorial(n - 1)
```

Note: Not all Phiton code can be dephitonized into Python code.

## Features

- Convert Python code to a compressed symbolic notation
- Adjustable compression levels (1-5)
- Preserve comments and type hints (optional)
- Command-line interface

## Installation

Using uv:
```bash
uv pip install phiton
```

or legacy pip: 
```bash
pip install phiton
```

Or from the repository:

```bash
uv pip install git+https://github.com/twardoch/phiton.git
```

For development, you can install with extras:

```bash
pip install -e ".[dev,test]"
```

## Usage

### Command Line

Compress a Python file:

```bash
python -m phiton example.py
```

Read from stdin and write to stdout:

```bash
cat example.py | python -m phiton > example.phi
```

Preview compression without saving:

```bash
python -m phiton example.py --preview
```

Compress with specific options:

```bash
python -m phiton example.py --level=3 --comments=False --type-hints=False
```

Compress an entire directory:

```bash
python -m phiton my_project/ --output-path=compressed/
```

Show version:

```bash
python -m phiton version
```

### Python API

```python
from phiton import compress_string, compress_file, ConversionConfig

# Basic usage
result = compress_string("def hello(name: str) -> str:\n    return f'Hello, {name}!'")
print(result["result"])  # Compressed code
print(result["stats"])   # Compression statistics

# With custom configuration
config = ConversionConfig(
    level=3,             # Compression level (1-5)
    comments=False,      # Don't preserve comments
    type_hints=True,     # Preserve type hints
    minify=True,         # Minify the code
    symbols=True,        # Use symbol substitution
)
result = compress_string("def hello(name: str) -> str:\n    return f'Hello, {name}!'", config)

# a file
stats = compress_file("example.py", "example.phi", config)
```

## Compression Levels

Phiton offers 5 compression levels:

1. **Basic**: Minimal symbol substitution, preserves structure and readability
2. **Moderate**: More symbol substitutions while maintaining readability
3. **Standard**: Full symbol substitution with some structure preservation
4. **High**: Aggressive symbol substitution and minimal structure
5. **Maximum**: Highest compression with shortest possible representation

# Phiton specification

Phiton is a symbolic notation for Python that uses Unicode characters to represent Python syntax in a more concise form. It's designed to compress Python code while maintaining readability for those familiar with math or physics notation.

## 1. Phiton syntax (concise spec)

---

Phiton compresses Python into Unicode symbols. Control flow symbols (⇐ for return, ↥ for yield, ⟳ for while, ∀ for for, ⋔ for if, ⋮ for else, ⊘ for pass, ⊠ for break, ⋯ for continue), operators (≔ for =, ≡ for ==, ≠ for !=, ∈ for in, ∉ for not in, ∧ for and, ∨ for or, ¬ for not, ≤ for <=, ≥ for >=), special values (∅ for None, ⊤ for True, ⊥ for False), function definitions (ƒ for def, λ for lambda, Σ for class, ⊡ for async/await), block structure (⟨...⟩ for indented blocks, → for statement separator), common functions (ℓ for len, ℜ for range, ℯ for enumerate, φ for filter, ℤ for zip, ς for sorted, ℛ for reversed), domain prefixes (№ for numpy, ℗ for pandas, χ for sklearn, μ for matplotlib, Ψ for torch, Φ for tensorflow), and literals (#123 for numbers, $text for strings).

---

## 2. Phiton syntax (detailed spec)

### 2.1. Introduction

Phiton is a symbolic notation system that represents Python code using Unicode characters, designed to create more concise and visually distinctive code while maintaining readability for those familiar with the notation. It serves as both a compression format and an alternative syntax that can highlight the structural and functional aspects of Python code.

### 2.2. Rationale

The development of Phiton is motivated by several goals:

1. **Code Compression**: Reduce the physical size of Python source code while preserving its semantic meaning
2. **Visual Distinctiveness**: Make code patterns more immediately recognizable through unique symbols
3. **Semantic Clarity**: Use mathematical and logical symbols that closely match their programming concepts
4. **Pattern Recognition**: Standardize common Python idioms into concise symbolic patterns
5. **Domain-Specific Optimization**: Provide shorthand notation for common library operations
6. **Flexible Compression**: Support different levels of compression based on needs

### 2.7. Compression Levels

Phiton supports different compression levels:

1. **Level 1**: Basic conversion with readable symbols and preserved structure
2. **Level 2**: More symbol substitutions but maintain readability
3. **Level 3**: Full symbol substitution with some structure preservation
4. **Level 4**: Aggressive symbol substitution and minimal structure
5. **Level 5**: Maximum compression with shortest possible representation

### 2.8. Conversion Process

#### 2.8.1. 6.1 Python to Phiton (`phitonize`)

1. Parse Python code into AST
2. Traverse AST and convert each node to Phiton notation
3. Apply pattern replacements for common idioms
4. Apply compression optimizations based on level
5. Generate symbol table for frequently used expressions
6. Optimize imports and structure

#### 2.8.2. 6.2 Phiton to Python (`dephitonize`)

1. Apply symbol replacements to convert Phiton to Python
2. Replace numeric and string literals
3. Fix function definitions and calls
4. Process blocks and indentation
5. Validate the decompressed Python code

### 2.9. Examples

#### 2.9.1. 7.1 Factorial Function

**Python:**
```python
def factorial(n):
    if n <= 1:
        return 1
    else:
        return n * factorial(n - 1)
```

**Phiton (Level 3):**
```
ƒfactorialn⟨⋔n≤#1⟨⇐#1⟩⋮⇐n*factorialn-#1⟩
```

#### 2.9.2. 7.2 List Comprehension

**Python:**
```python
[x * 2 for x in range(10) if x % 2 == 0]
```

**Phiton (Level 3):**
```
[x*#2∀x∈ℜ(#10)⋔x%#2≡#0]
```

#### 2.9.3. 7.3 Class Definition

**Python:**
```python
class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age
    
    def greet(self):
        return f"Hello, my name is {self.name}"
```

**Phiton (Level 3):**
```
ΣPerson⟨ƒ__init__self,name,age⟨self·name≔name→self·age≔age⟩→ƒgreetself⟨⇐「Hello, my name is {self·name}」⟩⟩
```

### 2.10. Implementation Notes

1. **AST-based Conversion**: Both phitonize and dephitonize use Python's AST for reliable code transformation
2. **Pattern Priority**: More specific patterns take precedence over general ones
3. **Symbol Table**: Frequently used expressions are cached in a symbol table
4. **Scope Awareness**: Symbol substitutions respect Python scoping rules
5. **Validation**: Generated code is validated through AST parsing
6. **Error Handling**: Conversion errors provide detailed feedback
7. **Compression Optimization**: Advanced compression uses frequency analysis

### 2.11. Best Practices

1. Use compression level 1-2 for code that needs to be read frequently
2. Use level 3 for a balance of readability and compression
3. Reserve levels 4-5 for maximum compression when readability is less important
4. Document the compression level used in project metadata
5. Maintain a style guide for consistent Phiton usage in projects
6. Consider using syntax highlighting for Phiton code
7. Include original Python code in comments for complex transformations

# TODO

- [x] Add/update `dev` and `test` extras to `pyproject.toml`, 
- [x] Add/update an `all` extra that includes all dependencies
- [x] clean up `tests` folder
- [x] clean up `src/phiton/` folder, remove unused/unneeded files.

## Code Quality Tasks

- [ ] Fix linting issues:
  - [ ] Fix shebang issues (EXE001) - make files executable or remove shebangs
  - [ ] Update deprecated typing imports (UP035) - replace `typing.Dict` with `dict`, etc.
  - [ ] Fix module level imports not at top of file (E402)
  - [ ] Fix boolean-typed positional arguments (FBT001, FBT002) - make them keyword-only
  - [ ] Refactor complex functions (C901) - break down functions with complexity > 10
  - [ ] Fix functions with too many arguments (PLR0913)
  - [ ] Fix functions with too many branches (PLR0912)
  - [ ] Fix functions with too many statements (PLR0915)
  - [ ] Fix functions with too many return statements (PLR0911)
  - [ ] Fix blind exception catching (BLE001) - specify exception types
  - [ ] Fix shadowing of built-in names (A001) - rename variables like `iter` and `type`
  - [ ] Fix unnecessary `elif` after `return` statements (RET505)
  - [x] Add `__init__.py` to tests directory to fix implicit namespace package issues (INP001)
  - [ ] Fix variable naming conventions (N806) - use lowercase for variables

## Test Improvements

- [x] Fix pytest configuration:
  - [x] Resolve the conflict between pytest.ini and pyproject.toml pytest configuration
  - [x] Fix the `--cov=phiton` argument (should be `--cov=src/phiton`)

- [ ] Fix test failures:
  - [x] Fix indentation error in test_optimize_imports
  - [ ] Fix test_config_level_range - level validation issue
  - [ ] Fix test_compress_simple_level1 and test_compress_simple_level5 - expected output mismatch
  - [ ] Fix test_compression_levels - level 4 produces larger output than level 3
  - [ ] Fix test_config_options - comment settings not affecting output

## Feature Enhancements

- [ ] Implement decompression functionality (Phiton to Python)
