Formular Solver

[olliklee]

Complete crashes the app, when a variable accidently calls itself a few times:

{"id":6,"name":"test","formulas":[{"id":1,"formula":"[A][B]"}],"values":[{"id":1,"key":"A","value":"len(aaaaaaaaaa)"},{"id":2,"key":"B","value":"cos(2.7)"}]}

This runs in an exponential raising output string, but only if more variables are added. If the B variable is deleted, the functions acts normal.

No. It is exaclty working as defined. We just have to think about adjusting the logic to avoid this.

Only interesting thing is: Are you quite sure about the freeze? Well, even my emulator is well working. It's just a very long and hence maybelong building output.

I don't really know how to solve it. One could check whether the variable contains itself. But where to end? It could be that A contains B and B contains C and C contains D and D contains A and even much more complicated. One has to think about a cyclic checker... Well, I personally believe: "Shit in shit out" is a good option here, as long it is no crash. And the nested depth is threshold by (number of variables)^2. So it could be a big number, but no endless loop.
