switch 1.0.0

The missing switch statement

Switch

Default behaviour

def test_switch(val):
    ret = []

    with Switch(val) as case:
        if case(1, fall_through=True):
            ret.append(1)

        if case(2):
            ret.append(2)

        if case.call(lambda v: 2 < v < 4):
            ret.append(3)

        if case.call(lambda v: 3 < v < 5, fall_through=True):
            ret.append(4)

        if case(5):
            ret.append(5)

        if case.default:
            ret.append(6)

    return ret

assert test_switch(1) == [1, 2]
assert test_switch(2) == [2]
assert test_switch(3) == [3]
assert test_switch(4) == [4, 5]
assert test_switch(5) == [5]
assert test_switch(7) == [6]

Default fallthrough

from switch import Switch

def test_switch(val):
    ret = []

    with Switch(val, fall_through=True) as case:
        if case(1):
            ret.append(1)

        if case(2):
            ret.append(2)

        if case.call(lambda v: 2 < v < 4):
            ret.append(3)

        if case.call(lambda v: 3 < v < 5, fall_through=False):
            ret.append(4)

        if case(5):
            ret.append(5)

        if case.default:
            ret.append(6)

    return ret

assert test_switch(1) == [1, 2, 3, 4]
assert test_switch(2) == [2, 3, 4]
assert test_switch(3) == [3, 4]
assert test_switch(4) == [4]
assert test_switch(5) == [5]
assert test_switch(7) == [6]

C like switch shortcut

from switch import CSwitch
# CSwitch(valk) is equvalent to Switch(val, fall_through=True)
