Rust Cargo Manager (Python GUI)

A simple Cargo.toml dependency manager built with Tkinter. It lets you select a Rust project's Cargo.toml, search crates on crates.io, add them to the relevant sections (dependencies, dev-dependencies, build-dependencies), or remove existing ones. The app fetches the latest version and short description of each crate via the crates.io API. Source code: cargoManager.py.

Note: The app writes directly to your Cargo.toml. It automatically creates a .backup file as a safety copy.

Features

• Select and parse Cargo.toml
• List sections: dependencies, dev-dependencies, build-dependencies
• Search crates.io, open selected crate page in browser
• Add selected crate to chosen section
• Remove existing crate
• Status bar and progress indicator
• Automatic backup (Cargo.toml.backup)

Installation

1) Python version

• Python 3.9+ recommended

2) Install dependencies

From requirements.txt:

pip install -r requirements.txt

tkinter ships with Python. On some Linux distros, you may need to install it via your package manager (e.g., Ubuntu/Debian: sudo apt install python3-tk).

3) Run the app

python cargoManager.py

Usage

1. Click Select Cargo.toml and choose a Rust project file.
2. Left panel shows existing dependencies (section, name, current version, latest version, description).
3. In the right panel, enter a search term and press Search.
4. Pick a result; choose the target section (dependencies, dev-dependencies, build-dependencies), then Add to Selected.
5. To remove a dependency, select it from the left panel and press Remove Selected.
6. Use Open Crates Link to open the selected crate’s crates.io page.

Changes are written directly to Cargo.toml and a .backup is created.

Architecture & Technical Notes

• GUI: tkinter + ttk
• HTTP requests: requests
• TOML read/write: toml
• Uses crates.io REST API directly
• Main class: CargoManager (inherits from tk.Tk)
• Progress bar shows network request delays for large dependency lists

---

Development

Using a virtual environment:

python -m venv .venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate
pip install -r requirements.txt

For code quality, consider adding: ruff, black

---

Packaging (optional)

You can build a standalone executable with pyinstaller:

pip install pyinstaller
pyinstaller --noconfirm --onefile --windowed cargoManager.py

The binary will be inside dist/.
