            # Uplevel

Access the values of variables in the parent scope. This package provides two commands: `upvar` and `uplift`.

## Installation

```bash
pip install uplevel
```

## Usage

Here is a short example of how to use `upvar` command:

```python
from uplevel import upvar

def fib(stop: int, step: int = 0):
    if step < 2:
        result = 0 if step == 0 else 1
    elif step <= stop:
        previous = upvar(1, 'result')  # result from previous iteration
        preprevious = upvar(2, 'result')  # and one iteration before
        result = previous + preprevious
    else:
        return upvar(1, 'result')
    return fib(stop, step + 1)

print(fib(20))
```

Here is another example for the `uplift` command:

```python
import re
from uplevel import uplift


def simplematch(regex, string):
    results = re.match(regex, string)
    uplift(1, 'match', results)
    return results


if simplematch(r"[abc]+", "abc123"):
    print(f"Matched: {match.group(0)}")
```
