Overview

This module provides functionality to:

• Process Code Files: Extract and list Python files from a ZIP archive.
• Generate Data Flow Diagrams: Create a data flow chart (in Graphviz format) by analyzing Python code using the AST module.
• Generate Documentation: Produce detailed documentation for Python code using multiple AI models:
  • Groq-based models (remote)
  • Gemini-based models (remote)
  • OpenAI-based models (remote)
  • OpenRouter-based models (remote)
  • Ollama-based models (local)
• Evaluate Documentation Quality: Compute BLEU/ROUGE scores to compare generated documentation against a reference document.

Usage

Processing Files:

from FastWrite import extract_zip, list_python_files, read_file
import tempfile
import os

# Specify the path to your ZIP file containing Python code
zip_file_path = "path/to/your/code.zip"

with tempfile.TemporaryDirectory() as tmp_dir:
    # Extract the ZIP file
    extract_zip(zip_file_path, tmp_dir)
    
    # List Python files in the extracted directory
    py_files = list_python_files(tmp_dir)
    
    if py_files:
        # For example, choose the first Python file as the main file
        main_file_path = os.path.join(tmp_dir, py_files[0])
        code_content = read_file(main_file_path)

Generating Data Flow Diagrams:

from FastWrite import generate_data_flow

# Generate Graphviz code for the data flow diagram
graphviz_code = generate_data_flow(code_content)
print(graphviz_code)

Generating Documentation (Express Mode):

# Normal Mode:
py -m FastWrite --LLM_NAME

# With custom code file
py -m FastWrite code_filename.py --LLM_NAME

# Simplified (Novice Friendly) Mode:
py -m FastWrite code_filename.py --LLM_NAME --Simplify

# Formal (Precise and to the Point) Mode:
py -m FastWrite code_filename.py --LLM_NAME --Formal

# Research (In-Depth and Elaborate Documentation):
py -m FastWrite code_filename.py --LLM_NAME --Research

# Custom (Allows you to feed a custom prompt of your own):
py -m FastWrite code_filename.py --LLM_NAME --Custom-Prompt "Enter Custom Prompt here"

Generating Documentation (Groq):
