# magic_extract

Based on https://andyljones.com/posts/post-mortem-plotting.html

Examples run in interactive python:

```python

from magic_extract import extract

def main():

    x = 3

    extract()

main()  # raises a RunTimeError

print(x)  # prints 3

```

```python

from magic_extract import debug

def main(x):

    y = x - 2

    return x / y

debug(main, 4)  # returns 2

debug(main, 3)  # returns 3

debug(main, 2)  # raises ZeroDivisionError and extracts

print(y)  # prints 0

```

```python

from magic_extract import decorate

@decorate()

def main(x):

    y = x - 2

    return x / y

main(4)  # returns 2

main(3)  # returns 3

main(2)  # raises ZeroDivisionError and extracts

print(y)  # prints 0

```
