👉🏾 See the project Roadmap

Learning Objectives

• Learn Python through hands-on practice
• Apply a clear and professional project methodology
• Deepen understanding of core concepts (modules, functions, data structures, etc.)
• Get introduced to modern tools in the Python ecosystem:
  • uv for dependency management
  • pyproject.toml for project configuration
  • Unit testing
  • argparse for command-line interfaces
  • And other tools/modules...
• GitHub Actions

---

Project Status

• ✅ Git repository initialized
• ✅ Python environment managed with UV
• ✅ Core logic implemented (add, list, complete, delete, clear)
• ✅ Priority filtering and sorting
• ✅ Fully tested with pytest
• ✅ Continuous Integration (CI) set up
• ✅ CLI welcome screen and helpful feedback
• ✅ Task metadata: created and due dates
• ✅ Enhanced list display with --verbose
• ✅ Display of due date by default
• ✅ Support for multi-ID delete and complete
• ✅ Tagging system for tasks (e.g. --tags work,urgent)
• ✅ Filter tasks by tag(s) with --tags option
• ✅ Edit existing tasks (text, priority, due date, tags)

Quick Install (Recommended)

If you just want to use the todo CLI tool without cloning the repository, you can install it globally using pipx:

brew install pipx
pipx ensurepath
pipx install todo-cli-x

Once installed, run the CLI from anywhere in your terminal:

todo --help
todo add "Submit report" --priority high --due 2025-06-10
todo add "Refactor API" --priority high --due 2025-06-30 --tags dev,urgent
todo list
todo list --verbose
todo list --tags dev
todo edit 1 --text "Finalize report" --priority medium --due 2025-07-01 --tags work,report

To upgrade later:

pipx upgrade todo-cli-x

Clone the repository:

git clone https://github.com/vidjinnangni/todo-cli.git
cd todo-cli

Set up the environment using uv:

uv sync

(Optional) Activate the virtual environment manually:

(macOS and Linux)

source .venv/bin/activate

Task Storage

• All tasks are stored in ~/.todo-cli-x/todo_data.json (automatically created on first use), so your list is the same no matter which directory you run todo from.
• Set the TODO_CLI_DATA_FILE environment variable to use a different location (e.g. a separate list per project).
• This file lives outside the repository, so it's never tracked by version control.
• You can see an example of the file format in examples/todo_data.example.json:

[
  {
    "id": 1,
    "text": "Buy milk",
    "done": false,
    "priority": "medium",
    "created": "2025-06-01T12:00:00+00:00",
    "due": "2025-06-15",
    "tags": ["shopping", "errands"]
  }
]

Usage

Run the CLI tool without activating the environment:

uv run todo add "Submit report" --priority high --due 2025-06-10
uv run todo add "Refactor API" --priority high --due 2025-06-30 --tags dev,urgent
uv run todo list
uv run todo list --verbose
uv run todo list --tags dev
uv run todo edit 3 --text "Finalize report" --priority medium --due 2025-07-01 --tags work,report

command todo list

command todo list --verbose

Or activate the environment and use todo directly:

source .venv/bin/activate
todo add "Submit report" --priority high --due 2025-06-10
todo add "Refactor API" --priority high --due 2025-06-30 --tags dev,urgent
todo list --tags dev

Running Tests

First, install all dependencies:

uv sync --extra dev

Then run the tests:

uv run pytest

Or:

source .venv/bin/activate
pytest
