rector | Instant Upgrades and Automated Refactoring | Parser library

I have come to the stackoverflow gurus for a better understanding and possibly a better solution to what is going on. So I'm typically pretty good with Makefiles but there is a critical piece that I am missing with my Makefile. So I typically have a one Makefile fits all for my projects and it works pretty well. Or it did until I found out that I wasn't linking the libraries properly. Since I discovered that my Makefile has been incorrect and I have been having trouble figuring out a way to solve this / have a better solution.

What I want to do

Let's say I have some .cpp files (ignore the awful naming)

I am new to project reactor, while I am studying the project reactor I observed one thing, always project rector logs get print as the main tread. if reactor runs without caring the thread, how that happens? and how I get verified reactive codes run on different different threads?

I wonder if you could give me a hint on how to get over the problem I encountered when trying to extract data from HTML files. I looked through other questions regarding the issue but still cannot figure out what changes exactly should I make. I have five HTML files in a folder. From each of them, I want to extract HTML links which I will later use. First, I extracted this data without any effort reading every HTML separately and creating a separate data frame for each HTML with much-needed links (/item.asp?id=). Then I used a 'rbind' function to merge columns from each data frame. The key here is that the first three HTML pages have 20 rows of the data I need, the fourth HTML has 16 rows, and the fifth and the last has 9 rows.

The looping code works just fine when I loop over the first three pages for which I have 20 rows each, but the code doesn't allow me to do the same for the fourth and fifth HTML pages because there the row number is different. I get the problem: Error in [[<-.data.frame(*tmp*, i, value = c("/item.asp?id=22529120", : replacement has 16 rows, data has 20 The code is as follows:

hello i'm using css counter to display the number of div that have a specific class inside a section but i don't know why the result of my code is alwase 0 this the code

following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.

I'm working on symfony 2.8 project and I'm new in it. Now I try to upgrade it to the newest version. I found the rector package for update the symfony (rector-prefixed exactly, for older version). I've install it and try to run like it is in documentation: https://github.com/rectorphp/rector, and got this error in the console:

I used to use phpexcel, but I want to move to phpspreadsheet.
I tried to hit the command based on the following site, but it doesn't work.
Did I make a mistake?
I'm also using a container named phpexcel in my code, is this still available?

Command

Last days I try to upgrade my project step by step. I have Symfony 2.8, composer 2. Lately I found rector/rector package for upgrading, but there was conflicts when I try to install it. Next I try to install rector/rector-prefixed. It also gives many problems with installation, but after research I've update my php version to 7.4 and it goes good. I've made composer update and install, but in the meantime new error shows up. With AppKernel. Before there was everything good and the app works fine. Now I've got message in the browser: Composer detected issues in your platform: "Your Composer dependencies require a PHP version ">= 7.4.0". "

And in the console after every command (for example: php app/console list) now I'm getting this message:

I recently started using Haskell and it will probably be for a short while. Just being asked to use it to better understand functional programming for a class I am taking at Uni.

Now I have a slight problem I am currently facing with what I am trying to do. I want to build it breadth-first but I think I got my conditions messed up or my conditions are also just wrong.

So essentially if I give it [“A1-Gate”, “North-Region”, “South-Region”, “Convention Center”, “Rectorate”, “Academic Building1”, “Academic Building2”] and [0.0, 0.5, 0.7, 0.3, 0.6, 1.2, 1.4, 1.2], my tree should come out like

But my test run results are haha not what I expected. So an extra sharp expert in Haskell could possibly help me spot what I am doing wrong. Output:
