The [main site](https://typer.tiangolo.com/) has docs and everything. This [youtube video](https://www.youtube.com/watch?v=8-i3U_3Gxko) is a good introduction.

## Installing
```bash
python -m pip install 'typer[all]'
```

## Examples
A simple example. We use [rich](RichPrint) for printing in colour -- [ansicolors](AnsiColors) is an alternative here.
```python
#!/usr/bin/env python
import typer
from rich import print

app = typer.Typer(name="Mr Flibble")

@app.command()
def hello(name: str):
  print(f"Fry [red]{name}[/red] with our [orange]hex vision[/orange]!!!")

@app.command()
def disobey():
  print(f"[yellow]Mr Flibble[/yellow] is [red]very cross[/red]")

if __name__ == "__main__":
  app()
```
