compile
method
The compile method is trying to pre-calculate all intermediate results of the formula. I'll show you an example:
>>> import formulas
>>> builder = formulas.Parser().ast('=MYFUNC((1+2)+a)')[1]
>>> builder.dsp.plot()
the Parser
has generated a Builder
with the following Dispatcher
:
When compile the function, the Builder
has generated a new Dispatcher
with all pre-calculated outputs (see (1+2)
).
>>> func = builder.compile()
>>> func.plot()
In this case the builder couldn't execute the MYFUNC, because it has has a variable as input. But if you execute the compiled function you will get the same error:
>>> func(1)
Traceback (most recent call last):
...
schedula.utils.exc.DispatcherError: ("Failed DISPATCHING '%s' due to:\n %r", 'MYFUNC', FunctionError('Function not implemented!',))
Error description
In the first case your function has not any variable, so the compile
method executes the function MYFUNC
raising the error.
While, in the second case, since the function has a variable as input, the compile
method cannot execute the function. In any case, you will receive the same error in the first execution of the compiled function.
Detect not implemented functions
If you want to detect not implemented functions, you can do the following:
>>> [k for k, v in builder.dsp.function_nodes.items() if v['function'] is formulas.functions.not_implemented]
['MYFUNC']
from formulas.
Thanks a lot for the explanation.
It was very helpful!
