cargo-aidoc 0.1.0

Add your description here

cargo-aidoc

cargo-aidoc is a Python script that leverages Large Language Models (LLMs) to automatically generate documentation comments for Rust code items like functions, structs, enums, etc.

Features

• Analyzes Rust source files using tree-sitter.
• Identifies documentable items (functions, structs, enums, etc.).
• Uses LLMs (configurable via mirascope) to generate documentation comments.
• Integrates with Git to prevent overwriting uncommitted changes (can be overridden with --force).
• Configurable via cargo-aidoc.toml.
• Supports dry runs to preview generated documentation.

Installation

This project uses uv for package management.

uv tool install cargo-aidoc

Usage

Run the script pointing it to the root of your Rust crate:

cargo aidoc /path/to/your/rust/crate

Options:

• CRATE_PATH: (Required) The path to the Rust crate directory.
• -q, --quiet: Disable verbose output.
• --dry-run: Generate documentation but do not write changes to the files.
• --force: Ignore the Git uncommitted changes check and modify files directly.
• -c, --clean-cache: Remove the .cargo-aidoc cache directory after execution.

Example:

# Generate docs for a crate, showing verbose output, but don't modify files
cargo aidoc . --quiet --dry-run

# Generate and write docs, forcing overwrite even with uncommitted changes
cargo aidoc . --force

Configuration

The script looks for a cargo-aidoc.toml file in the root of the target crate. If it doesn't exist, a default one will be created.

Default cargo-aidoc.toml:

[llm]
# Configuration passed to mirascope.llm.call
# See mirascope documentation for options
provider = "openai"
model = "gpt-4o"
call_params = {} # e.g., {"temperature": 0.5}

[doc]
# Glob pattern relative to the crate root for source files
source = "src/**/*.rs"
# Types of items to document
item_types = ["fn", "struct", "enum", "union", "trait", "macro", "static"]

You can customize the LLM provider, model, call parameters, source file pattern, and the types of Rust items you want to document.

Dependencies
