restraint | Simple test harness which can be used with beaker

I have a question that has been touched upon by different answers but as far as I can find not in the same details as I require. I wish to unbind an event listener, but with a couple of restraints.

1. Event delegation to child items
2. The event listener takes a secondary argument
3. The event function must unbind itself inside an if-clause

I dumbed it down to the example below. When you click the first button, you can then click any of the other buttons. The text of the first button will change accordingly. However, because the event listener is never removed you can keep changing your "choice" and click on any of the other buttons. What I want is that when you click on the first button, you can only click on one other button after which the listener is removed. In practice that means that if you want to change your "choice" you first need to click the first button again, after which the event listener is re-attached.

The Explanation:

It is part of a study I am doing. I am not allowed to change the filenames of the mp3 files, I have to somehow do this from the script and keep it as short a script as possible. The script itself is a menu that will have the user select a chapter, then the part of the chapter and from there on they can listen to the text in my language, transliteration in their language and then the sentence in their language/alphabet.

I have to simplify matters by creating a script that makes a menu inside bash. All works quite well and I automated a lot already. So that part is done and I don't need the question answered for the problem below as this basically works as it is.

And it has to be bash scripted, not python or anything else.

Also English is not my native language, so please bare with me!

The Situation:

So I ran into a situation where I need to add the function to play audio files inside a menu script. I am unsure how to explain it any better than by giving examples.

Basically all works well except for one thing.

I have a set series of mp3 files ranging from 001001.mp3 to 114006.mp3

They used their naming convention to have the first three numbers as chapter, last three as parts of the chapter. To me it is odd as I would have created a different structure and can't right now as these files are being used already.

Now I can get the numbers of the first three automatically by generating those numbers by input (read -p ": " chapternumber). But the second is more tedious to get inside the script as I count from 1 to a maximum needed of 300 but without leading zeros, 0 or 00. And I can't simply use read -p to achieve this as it will automate based on the input of the numbers I give it.

Example of filenames:

Every class that you create in Python implicitly derives from object. To create a new error class, you must derive it from BaseException or one of its child classes (usually, Exception is used for this purpose). This custom exception will successfully pass the isinstance(MyException, object) test, so it's still an object. But I wonder, what's the reason this restraint was implemented? Why do we need to derive from BaseException or its descendants instead of doing like this:

I'm quite new to mobile development and still learning the restraints. Is it possible to change the DarkMode in an Android device's settings and, if so, how do I change it?

The code below is a simplified version of my app. When the EnableSwitchChanged() method is called, I would like to toggle the value of the DarkMode setting in the devices settings.

My goal is to save in a file the callstack state when an exception is raised. But I have one major restraint: I cannot touch any of the existing code. My goal is to implement that in a context where I'm unaware of the current workflow. So I can use it in any C# Project.

To do so I need to have access to all the nested methods that lead to the exception but also all the method's arguments.

Until now I used postsharp OnMethodBoundaryAspect which allow me to define OnEntry, OnSucess, and OnException method that is called whenever a method: is entered, returns, or raise an exception. What is great is that I can apply this aspect with a postsharp.config file in the project I want. No source modification, I'm only adding my project to the solution, a config file, and reference to my project in every project of the solution and I'm good to go. Using that I could maintain a callstack of my own, and I could save references to methods' name, and ref to methods' arguments.

Now let's say a methodA calls a methodB which calls a methodC.

What I've done works well except that obviously I use references. So if methodA argument is modified in methodC just before raising an exception, when I serialize the call stack, We'll see a call stack where methodA has an argument with a wrong value (we'll see the value set in methodC).

I want to fix this issue and I considered using:

1. deepcloning in the OnEntry method to copy all the methods parameters but that would lead to awful performances
2. PostSharp LocationInterceptorAspect but that requires a paid licence
3. VEH Hooking but it is incredibly slow and it would probably be faster to use deepcloning

Is there any other way that would allow me to save the state of an object in time with greater performances than deepcloning, or at least let me intercept all modifications brought to a specified object (like the VEH hooking or the LocationInterceptor Aspect)?

PS: I can't use IOnPropertyChange or things like that because I can't touch any of the existing sourceCode except if I can implement them at runtime but I didn't see anywhere that it was possible.

I am trying to populate a google sheet using an API. But the API has more than one row to be returned for a single query. Following is the JSON returned by API.

I'm attempting to call a Graph QL Query after receiving data from my useEffect hook. I need the data from the response to use in the Query. Hooks however cannot be called conditionally. If I take away the condition however, loadedAnime will be undefined. How do I get around this restraint?
