#Matchete
Really dirty and hacky prototype, don't use
Overload methods of python classes depending on the behavior of the passed arguments:
- containing an attribute
- responding to a method call
- having a type
- responding to a method call with a certain value
- having the same list structure
example:
from matchete import on, Any, eq, matchable
@matchable
class A(object):
@on('#meow')
def a(self, cat):
cat.meow()
@on('#talk')
def a(self, human):
human.talk()
@on(eq('.color', 'white'))
def a(self, white):
return True
@matchable
class Matcher(object):
@on('#node_type', '#node_type')
def match(self, left, right):
code
@on('#node_type', Any)
def match(self, left, right):
other_code
@matchable
class Combinator(object):
@on([str])
def combine(self, values):
return ''.join(values)
@on([int])
def combine(self, values):
return ' '.join(str(v) for v in values)
@on(is_in('.value', range(0, 10)])
def combine(self, value):
return str(value)
