Multiplexer/Lookuptable Chip

Joker

A useful refactoring tool would be a multiplexer. This is a chip that takes multiple inputs, and chooses one value from those inputs to output on a single output, where that choice is made by the value of a selector pin.

Joker This capability is available using the List chip. There is no need for this suggestion ! [|=)]

yoes: So why did you vote for it?

yoes: Looking back at it, you do seem to be right. The Make List and Get Element chips together serve exactly this function. It's not super clear, but it's spot on.

And honestly it's probably easy enough to resolve that unclearness by packaging those together in a neat circuit board with some labels.

I happen to use the pattern in the image below again and again, but it feels utterly complicated for such a simple task. It takes a value and replaces it with another one using a lookup table.
I see two options to implement the chip:
1) 1 input, 1 output, reset pins. The menu looks similar to the selector chip, but allows inputting a second number that is the value the chip outputs instead of the input value.
2) 7 inputs, 1 output, reset pins. The menu is the same as the selector chip's, but only has 6 entries. The red input still determines which row in the menu is selected. But it selects from the other (green to black) input pins and outputs that value to the one output pin.
This is pretty much a reverse selector chip (apparently this is called multiplexer). In this variant the reset pins could be replaced by an additional input.
