autodoc-cli 0.2.1

CLI to auto-generate C doc comments using Tree-sitter and Ollama

AutoDoc

CLI tool that generates documentation comments for source code using Tree-sitter parsing and a local Ollama model. Initially supports C (.c, .h).

Requirements

• Python 3.12+
• uv for environment management
• Ollama running locally with a compatible code model (e.g., qwen2.5-coder:7b)

Install

Development Installation

# Clone the repository
git clone https://github.com/pierrelgol/autodoc-cli.git
cd autodoc-cli

# Create virtual environment and install in development mode
uv venv --python 3.12.11
uv pip install -e .[dev]

Production Installation

# Install from PyPI (when published)
uv pip install autodoc

# Or install from local wheel
uv pip install dist/autodoc-0.1.0-py3-none-any.whl

Usage

# Basic usage
autodoc /path/to/target --model qwen2.5-coder:7b

# Dry run to see what would be changed
autodoc /path/to/target --dry-run

# Use a different model
autodoc /path/to/target --model llama3.1:8b

# Specify a custom database location
autodoc /path/to/target --db /path/to/custom.db

# Example: Generate documentation for a C project
autodoc /path/to/c-project --model qwen2.5-coder:7b

By default, a SQLite DB .autodoc.sqlite will be created in the target directory to track function body hashes for change detection.

How it works

• Tree-sitter is used to parse C files into ASTs. No regex is used for detection.
• For each function:
  • If a doc comment exists and the function hash matches the DB, the function is skipped.
  • If a doc exists but the hash changed, the doc is regenerated and replaced.
  • If no doc exists, a new doc comment is generated and inserted above the function.
• Edits are applied directly to the source files and are idempotent.

Example

Before running autodoc:

int calculate_fibonacci(int n) {
    if (n <= 1) {
        return n;
    }
    return calculate_fibonacci(n - 1) + calculate_fibonacci(n - 2);
}

After running autodoc . --model qwen2.5-coder:7b:

/**
 * Calculates the nth Fibonacci number using recursion.
 *
 * @param n The position in the Fibonacci sequence (0-based).
 * @return The Fibonacci number at position n.
 */
int calculate_fibonacci(int n) {
    if (n <= 1) {
        return n;
    }
    return calculate_fibonacci(n - 1) + calculate_fibonacci(n - 2);
}

Notes

• Only C is supported currently. Additional languages can be added by implementing the LanguageAdapter interface in autodoc/adapters.
• Ensure Ollama is running locally: ollama serve and that the model is available: ollama pull qwen2.5-coder:7b.
• If you prefer uvx, be aware that uvx autodoc may resolve to the PyPI package named autodoc. Use the local script instead: .venv/bin/autodoc.
