The warping basically sorted itself out as things were mounted to the shell, as we’ll see. The 3D print came in, and it was warped a little bit once again, but much less than before.

If it was still warped, my friend and I had some ideas for how to straighten it. I already had tabs in the model for holding the LCD panel and control board, so I simply extended those to the edges to form stiffeners. I made some changes to my design, most notably adding more structural ribbing on the underside. Building a vacuum former was fun, but after talking to a friend with a lot more 3D printing experience than me, I decided to give that another whirl. Most recently, I decided maybe I didn’t want to fill my oven with toxic fumes after all, and abandoned my plan to vacuum form the shell. Unfortunately, this project has pretty much been one set back after another ever since. You may assume that the input will only contain spaces, digits, and the 5 characters you choose.Į=>e.A while back, I had this idea to create a thing that would turn an Apple IIc into a laptop. Input will be given as a string and output as an array, a single integer, out the string representation of either. You may take the anyfix official interpreter and golf it if you would like.+×'10 10 -> 200 (after the 10 is duplicated (duplication is delayed), 10 + 10 is performed and then 20 * 10, giving 200) Test Casesįor these test cases, duplicate is ', negative is -, addition is +, multiplication is ×, and equality is =.

This is code-golf so the shortest code in bytes wins. Your program can either output the singular array or the value contained by it it is guaranteed that the stack of values will only contain a single value at the end of execution and that the queue of operators will be empty at the end of execution. Select a set of 5 non-whitespace non-digit characters and create an anyfix interpreter according to the specifications above. (Disclaimer: Your submissions will not be used in the anyfix interpreter) Challenge The commands used in these demonstrations are consistent with that of the anyfix language however, the last example will not work due to a bug in my interpreter.

10: The stack becomes, which allows + to be evaluated.× can now be evaluated, which makes the stack and the queue. Even though × should be the first operator to be evaluated since it appears first, ' can run immediately and none of the operators before it can, so it is evaluated. ': The stack is unchanged and the queue becomes.+: The stack is unchanged and the queue becomes.×: The stack is unchanged and the queue becomes.+ can now be evaluated so the stack becomes and the queue. This can run immediately so it is, making the stack. Next, + is evaluated, which doesn't change the stack (because there are not enough arguments) and makes the queue. 10 is evaluated first which makes the stack. Let's take a look at a harder example: 10+'. The final result should be for + 10 5, 10 + 5, and 10 5 +. At this point, the operator '+' can be evaluated so it is, making the stack and the queue. Then, the literal 5 is evaluated which makes the stack. However, there is only one argument on the stack, so the queued operator list becomes. Next, the operator + is evaluated, which requires two arguments. Then, the literal 10 is evaluated which makes the stack. So first, the stack starts at, and the queued operator list starts at. The storage should behave as a stack, not a queue. For demonstrational purposes, I will use ' as duplicate, × as multiplication, and + as addition.įor literals, you only need to support non-negative integers, but your interpreter must be able to contain all integers (within your language's (reasonable) integer range). You may choose to use any five non-whitespace symbols for these commands. You will need to support the following commands: (Arity 1) (Note that anyfix is a recreational language that I abandoned that you can play around with here or check out here) For this challenge, you are to implement a very basic anyfix evaluator. If an operator shows up and there aren't enough arguments, then the operator waits until there are enough arguments. In anyfix notation, the operator can go anywhere *. In postfix notation, the operator comes after the arguments, so you can just imagine it as stack-based. In infix notation, the operator goes between the arguments, so you can imagine it simply as a parse tree. In prefix notation, the operator comes before the arguments, so you can kind of imagine that the operator calls next() which is recursively called.
