Usage

Adding functions to Formula

from redbeaver.formula import Formula

f = Formula()

print f

{'fn_registry': {}, 'num_registry': {}, 'param_registry': {}}

@f(1)
def a(b, c):
    return b + c

print f

{'fn_registry': {'a': (('args', ['b', 'c']), ('src', ([u'@f4(1)\n', u'def a(b, c):\n', u'    return b + c\n'], 1)), ('call', <function wrapped_fn at 0x10fb28ed8>))}, 'num_registry': {1: <function wrapped_fn at 0x10fb28ed8>}, 'param_registry': {}}

@f(2)
def b(c):
    return 2 * c

print f

{'fn_registry': {'a': (('args', ['b', 'c']), ('src', ([u'@f4(1)\n', u'def a(b, c):\n', u'    return b + c\n'], 1)), ('call', <function wrapped_fn at 0x10fb28ed8>)), 'b': (('args', ['c']), ('src', ([u'@f4(2)\n', u'def b(c):\n', u'    return 2 * c\n'], 1)), ('call', <function wrapped_fn at 0x10fab9ed8>))}, 'num_registry': {1: <function wrapped_fn at 0x10fb28ed8>, 2: <function wrapped_fn at 0x10fab9ed8>}, 'param_registry': {}}

f(2)

<function __main__.wrapped_fn>

f('b')

(('args', ['c']),
 ('src', ([u'@f4(2)\n', u'def b(c):\n', u'    return 2 * c\n'], 1)),
 ('call', <function __main__.wrapped_fn>))

f('a')

(('args', ['b', 'c']),
 ('src', ([u'@f4(1)\n', u'def a(b, c):\n', u'    return b + c\n'], 1)),
 ('call', <function __main__.wrapped_fn>))

Parameters setting

f({'c': 5, 'd': 7})

f.get_params()

{'c': 5, 'd': 7}

f('c')

5

Formula calculation

from redbeaver.calc import Calc

calc = Calc(f)

calc('a')

15

f.get_params()

{'a': 15, 'b': 10, 'c': 5, 'd': 7}

Working with iterable params

f = Formula

calc = Calc(f)

@f(1)                                               
def a(b):                                           
    return b * 2                                    

@f(2)                                               
def b(c):                                           
    return c * 2                                    

f({'c': range(5)})                                  

calc('a', iterate_param='c')

[0, 4, 8, 12, 16]

f.get_params()

{'a': [0, 4, 8, 12, 16], 'c': [0, 1, 2, 3, 4], 'b': [0, 2, 4, 6, 8]}

Reset params

f.reset_params()
f.get_params()

{}
