Pattern matching for python.
Installation
pip install patterns
Usage
from patterns import patterns, Mismatch
@patterns
def factorial():
if 0: 1
if n is int: n * factorial(n-1)
if []: []
if [x] + xs: [factorial(x)] + factorial(xs)
if {'n': n, 'f': f}: f(factorial(n))
assert factorial(0) == 1
assert factorial(5) == 120
assert factorial([3,4,2]) == [6, 24, 2]
assert factorial({'n': [5, 1], 'f': sum}) == 121
factorial('hello') # raises MismatchSee tests for more examples.
TODO
docs
matching to _ should not capture
name parameter
better handling of Mismatch passing to function env
non-strict dict matching
