            How to type-constrain the entries of a Raku function's array argument?
            Asked 2021-Jun-15 at 23:08

            I am trying to define a subroutine in Raku whose argument is, say, an Array of Ints (imposing that as a constraint, i.e. rejecting arguments that are not Arrays of Ints).

            Question: What is the "best" (most idiomatic, or straightforward, or whatever you think 'best' should mean here) way to achieve that?

            Examples run in the Raku REPL follow.

            What I was hoping would work



            Answered 2021-Jun-15 at 06:40

            I think the main misunderstanding is that my Int @a = 1,2,3 and [1,2,3] are somehow equivalent. They are not. The first case defines an array that will only take Int values. The second case defines an array that will take anything, and just happens to have Int values in it.

            I'll try to cover all versions you tried, why they didn't work, and possibly how it would work. I'll be using a bare dd as proof that the body of the function was reached.

            From what it looks like, options is actually an array of objects rather than just an object. So all you would need to do is map over the options variable. You are currently using Object.keys which is what you use if you are wanting to iterate over the keys in an object.

            Why does TypeScript infer this type for the array item with a union of array types?
            Asked 2021-Jun-15 at 19:42

            I'm having trouble understanding why TypeScript is inferring a certain type for an array element when the type is a union type and the types 'overlap'. I've reduced it to this minimum repro:



            Answered 2021-Jun-15 at 19:42

            See microsoft/TypeScript#43667 for a canonical answer. This is a design limitation of TypeScript.

            As you might be aware: in TypeScript's structural type system, Child is a subtype of Base even though it is not explicitly declared as such. So every value of type Child is also a value of type Base (although not vice-versa). That means Child | Base is equivalent to Base... although the compiler is not always aggressive about reducing the former to the latter. (Compare this to the behavior with something like "foo" | string, which is always immediately reduced to string by the compiler.)

            Subtype reduction is often desirable, but there are some places where Child | Base's behavior is observably different from Base's, such as excess property checks, IntelliSense hinting, or the sort of unsound type guarding that happens with the in operator. You haven't shown why it matters to you that you are getting a Base as opposed to a Child | Base, but presumably it's one of these observable differences or something like it.

            My advice here is first to think carefully about whether or not you really need this distinction. If so, then you might consider preventing Base from being a subtype of Child, possibly by adding an optional property to it:

            Meaning of Compile-Time?
            Asked 2021-Jun-15 at 19:35

            My Question: What exactly does “compile-time” mean? I present my understanding below and where I am getting confused.

            Compilation is the process that generates a single executable .exe file from the .vb file. There are several ways to do this, for example by using the VBC.EXE command from the developer command window or MSDOS. The way I understand “compile-time” is that it is time when such a command gets executed and the exe file is generated. The following are the what I find confusing:

            1. When I write Dim i = 5, the compiler infers or “knows” that the variable “i” is an integer.
            2. If I want to print an integer or a string using the Writeline method of the console class then the compiler automatically determines which overloaded version it should call. So in this case also the compiler “knows” – this is also known as compile-time polymorphism.

            My confusion: Since in both the above cases the compiler infers or knows the type of variable or the version of the overloaded method to call just after we have finished typing the sentence, is this also called compile-time? We have not given any sort of compilation command here.

            1. Another confusion on the definition of compile-time refers to the case when we explicitly define overloaded methods. In the case of the writeline method, we know from the pop-up given by intellisense that immediately after we have finished typing the sentence the version with the correct signature is called. Now, when we define overloaded methods does the compiler know which version to call when we call the function (depending on signature) somewhere in the program right after we have finished typing the code? Or does the compiler know this after the exe file has been generated? This is a case of compile-time polymorphism. But then which time or which step is the “compile-time”?


            Answered 2021-Jun-15 at 19:35

            We have not given any sort of compilation command here.

            No, but most modern IDEs can do similar "static analysis" that compilers do to determine types, etc. Some even do a very lightweight "compile" to determine what overloads are appropriate, etc.

            Also note that IDEs and the actual compiler may not always agree. IDE analysis is designed to be very fast, so the analysis done by the IDE may be less robust and less accurate than a static compiler.

            So in a sense these are all "compile-time" in that the only information that is available is what is present in the code. This is opposed to "run-time" where other factors such as user input, environment, and state can change the flow and interpretation of the program in ways that the compiler could not account for.

            Find proportion of times each character(A,B,C,D) occurs in each column of a list which has 3 datasets
            Asked 2021-Jun-15 at 19:00

            I have a list (dput() below) that has 4 datasets.I also have a variable called 'u' with 4 characters. I have made a video here which explains what I want and a spreadsheet is here.

            The spreadsheet is not exactly how my data looks like but i am using it just as an example. My original list has 4 datasets but the spreadsheet has 3 datasets.

            Essentially i have some characters(A,B,C,D) and i want to find the proportions of times each character occurs in each column of 3 groups of datasets.(Check video, its hard to explain by typing it out)



            Answered 2021-Jun-09 at 19:00

            We can loop over the list 'l' with lapply, then get the table for each of the columns by looping over the columns with sapply after converting the column to factor with levels specified as 'u', get the proportions, transpose, convert to data.frame (as.data.frame), split by row (asplit - MARGIN = 1), then use transpose from purrr to change the structure so that each column from all the list elements will be blocked as a single unit, bind them with bind_rows

            VBA - NULL values in Listview
            Asked 2021-Jun-15 at 17:10

            I've created a simple VBA interface to connect Excel to a MySQL DB. The VBA part acts as a preview of data for the user to choose what item he wants to import to the Excel sheet.

            Until now I've work with a very complete set of data, but I got to a Table which (because of the nature of the items) some fields are NULL.

            Now every time I try to check the values in the VBA I get the Run-time error 13 Type mismatch in the listview component. At first I though it was a field with DECIMAL typing, but after changing it to a DOUBLE (for testing) the problem persisted, and it was until I notice that if only checks columns with no NULL value, the problem disappears. Off course I can't omit this values.

            I tried some .Tostring functions but with no success. And I failed to implement a IF to check for NULL in the obj.

            This is my code:
