Map Function

[Ali Ozdemir]

Assume I have 2 repeat objects like below.

    <O N="D" T="DesignCode">
        <O N="D1" T="Repeat" S="0" E="10" I="1" CTRL="ii" ii="0">
            <O N="D2" T="Repeat" S="0" E="10" I="1" CTRL="jj" jj="0">
                <P N="Fu" V="jj*ii" />
            </O>
        </O>
        <P N="mappedFu" V="map(D1[2].D2, Fu)" />
    </O>

mappedFU returns to 0,0,0,0,0... Is this expected behavior?

I would like to map all Fu parameters to a list but couldn't figure out. Is it possible to show me an example?

It is really hard to say what the behavior is supposed to be in this case, but I can see what you are trying to do. I think we need a new function for this.

Note that you have multiple parameters named Fu here -- that is what Repeat object implicitly do. It repeats and hence generates multiple instances of its content. If we have a function that can take the values of all parameters named Fu, or all objects named a certain name (while in your example there is no object inside the repeat, you could), then you would be able to get the list of numbers you want.

I will keep this open to track the implementation of this new function.

[Ali Koc]

a new function allowing us to collect a list of objects or parameters by name inside an object (or root project object by default).

[Ali Koc]

As of v3.17.0115, you can use params() and objs() functions to create a list of parameters or objects. Documentation is pending, but here is how you can handle your case. Change the value of mappedFu to:

 <P N="mappedFu" V="params('Fu')" />

Let me know if this does not solve your issue.

this is resolved, thanks
