Infix to postfix (RPN) converter and solver
hi @gumm
this project looks really nice!
i'm thinking of using it in combination with cellx to prototype a micro excel-like thing. i see that your other dag-solve lib is in the same area of interest :)
would it be possible to add support for parsing custom function names with any number of params which can include named variables and nested functions, e.g. 3 + foo(A, bar(5, C))
. then calcRPN can accept an additional user-defined lookup function which can return either variable values or functions.
i could take a stab at it, but i suspect you could add this faster and more correctly.
thanks!
