archibate Python Build Tools
Modern Python development tooling using uv, mise, ruff, basedpyright, and pytest.
Quick Start
Minimal pyproject.toml
[project]
name = "my-project"
version = "0.1.0"
requires-python = ">=3.12"
dependencies = ["fastapi", "pydantic"]
[project.optional-dependencies]
dev = ["pytest>=8.0.0", "ruff>=0.8.0", "basedpyright>=1.0.0"]
[build-system]
requires = ["hatchling"]
build-backend = "hatchling.build"
[tool.ruff]
target-version = "py312"
[tool.ruff.lint]
select = ["E", "F", "I", "N", "UP", "RUF"]
[tool.basedpyright]
typeCheckingMode = "strict"
[tool.pytest.ini_options]
testpaths = ["tests"]
Setup Project
uv init my-project && cd my-project
uv sync
uv add fastapi pydantic
uv add --dev pytest ruff basedpyright
Tool Overview
| Tool | Purpose | Replaces |
|---|---|---|
| uv | Package management | pip, virtualenv |
| mise | Version & tasks | pyenv, asdf |
| ruff | Lint & format | black, isort, flake8 |
| basedpyright | Type checking | mypy |
| pytest | Testing | unittest |
Common Commands
Lint and Format
uv run ruff check --fix .
uv run ruff format .
Type Check
uv run basedpyright
uv run basedpyright src/main.py
Test
uv run pytest
uv run pytest --cov=src --cov-report=html
Manage Dependencies
uv add fastapi
uv add --dev pytest
uv lock --upgrade
uv tree
Mise Configuration
Create .mise.toml for consistent development:
[tools]
python = "3.12"
[tasks.lint]
run = "uv run ruff check --fix ."
[tasks.format]
run = "uv run ruff format ."
[tasks.typecheck]
run = "uv run basedpyright"
[tasks.test]
run = "uv run pytest"
[tasks.check]
depends = ["lint", "format", "typecheck", "test"]
Usage:
mise install
mise run check
Type Hints Example
from decimal import Decimal
from typing import Optional
def calculate_discount(
total: Decimal,
rate: Optional[Decimal] = None
) -> Decimal:
if rate is None:
rate = Decimal("0.1")
return total * rate
Best Practices
- Use uv for all package management (faster, reliable)
- Pin Python version with mise
- Configure tools in pyproject.toml
- Enable strict type checking
- Run checks before commit
