PatternMatching | simple library with extension methods | Assertion library

I am using patternmatching within a function as follows :

I have a spark dataframe with a binary string column. I want to add a column to a dataframe with indices of 1 in each element of the column.

I have a pattern matching function for getting indices but I need to apply this function to a spark dataframe column.

I have a siddhi cep application running on Android. Now I want to send events from event simulator from stream processing editor to android app via a socket connection. Till now I have been successful in making android server socket which listens to python client simulator made by me. But to ease the process, is it possible that I can use event simulator to send events to android siddhi app?

I was wondering if I can change some configurations such that event simulator sends events to android socket, so I looked at setting in deployment.yaml file

but the sending configurations are defined for HTTP

Because of a lot of intricacies in filename patternmatching in Windows (and former DOS) I'd like to call RtlIsNameInExpression from my .Net code to make sure my (console) application will behave identical to Windows applications. However, I don't seem to be able to find how to PInvoke this function; I have no idea what the DllImport should look like and I am unable to find any examples nor anything useful on pinvoke.net.

Any help would be appreciated!

EDIT: I was blind. I was googling FsRtlIsNameInExpression where I should've been googling RtlIsNameInExpression (explanation here).

Anyway; found something here and that seems to work.

I have a templated class in D that takes another template as a parameter, and it begins thus:

I am trying to figure out how to handle patternmatching cases where it returns different types depending on the match, I know it has to return the same type for each branch, so im not sure what the "proper" way to handle a situation like this is:

I tried to make an example of my confusion below, paintArr being an array representing a pallete that can contain Some color or an empty slot.

paintArr.[i,j].color being of type Color option, containing Black and white.

The pattern matching should for each slot decide wether the color is black or white and add its index to the appropriate array.

I'm trying out Reason and I'm trying to use a regex, but nothing is matching. AFAIK Reason doesn't have any specific regex related things so I'm just going off the OCaml documentation.

My string looks like:

I have a master list in master-detail app, when I set it to multi-select mode, I want to capture userIds of all the selected item. Is there any elegant way to pass these data to detail.controller.js through route?

my showDetail function in single select master page("pattern": "User/{objectId}"):

I'm writing a Linked List program in C# because I want to test how I feel about the language and I'm running into some serious difficulty. I'm trying to implement a Map method that functions like a Haskell map function (code below for both). However, I'm getting the error messages:
