### 🎯 Adoption Guide
|
|
|
|
For teams adopting the modern Python stack:
|
|
|
|
1. **Start with terminal-based development container**:
|
|
```bash
|
|
git clone https://git.cleverthis.com/cleverthis/base/base-python
|
|
cd base-python
|
|
docker build -f .devcontainer/Dockerfile -t boilerplate-dev .
|
|
docker run -it --rm -v $(pwd):/workspaces/boilerplate boilerplate-dev bash
|
|
```
|
|
|
|
2. **Experience the modern workflow**:
|
|
```bash
|
|
# All tools pre-installed and configured
|
|
nox -s behave # BDD testing with fuzzing
|
|
nox -s lint # Lightning-fast linting
|
|
nox -s format # Code formatting
|
|
nox -s typecheck # Strict type checking
|
|
```
|
|
|
|
3. **Understand the architecture**:
|
|
```bash
|
|
# Single configuration file
|
|
cat pyproject.toml
|
|
|
|
# Modern test specifications
|
|
cat features/cli.feature
|
|
|
|
# Cloud-native deployment
|
|
helm template test ./k8s
|
|
```
|
|
|
|
4. **Choose your IDE integration**:
|
|
```bash
|
|
# Terminal-first (recommended)
|
|
# Emacs with TRAMP
|
|
# Vim/Neovim inside container
|
|
# VS Code with Dev Containers
|
|
# PyCharm with remote interpreter
|
|
```
|
|
|
|
### 🤝 Contributing
|
|
|
|
The new development workflow emphasizes:
|
|
|
|
1. **Development containers** for consistent environments
|
|
2. **BDD-first development** - write scenarios before code
|
|
3. **Continuous quality** - nox runs all checks
|
|
4. **Type safety** - strict Pyright configuration
|
|
5. **Fast feedback** - tools run in seconds, not minutes
|
|
