# Pyper 

A pure functional wrapper on top of Typer

## Usage

Usage is almost identical to typer (which is used internally)

except instead of calling `typer.echo` which has a side-effect the

functions should yield `pyper.echo` which is a value object. 

```python

import pyper

def main(name: str):

    yield pyper.Echo(f"Hello")

    yield pyper.Echo(f"I will call you {name}")

    yield pyper.Echo(f"Bye")

if __name__ == "__main__":

    pyper.run(main)

```

## Why?

Having the functions yield makes them much easier to test with little

or no mocking:

```python

assert list(main("steve")) == [

    pyper.Echo("Hello"),

    pyper.Echo("I will call you steve"),

    pyper.Echo("Bye"),

]

```
