Sorry, I messed that up. I did not update the manifest from the last post and I forgot the content.js, that is how the Change button was sending the value and the page was getting the new style attribute value from the one entered in the text field and then to the content.js, existing content.js file added below.

I have a styles.css that changes the web page and is loaded from the popup but want to change a variable in the styles.css from the data entered at the popup.

I've added a content.js file and I can now pass a value from the Popup and it adds a new style attribute to the page but it's not updating the --ptwidth in the styles.css file. I think I need to have it in the styles.css to give the correct location and add the !important option.

I tried to ask this question before an it was closed\linked to one about webpage DOMs and don't have the reputation to post a comment and not sure I should ask my questions there if I could:

How to access the webpage DOM rather than the extension page DOM?

The styles.css injection works using the Wider button and the --ptwidth var is passed the value given (310) in the styles.CSS, at the very least I'd like to be able to enter a new value in the textbox and then use the existing Wider button to load the updated styles.css but it would be nice to have it auto update and maybe even use the slider.

The change button moves the new value entered in the text field to the content.js file and it then adds the new style attribute but it's not working. The insertCSS on the Wider button works but the info it adds is different.

Content.js adds the Style attribute section and the insertCSS adds the :root section that works.

I am trying to create an ul which has a li for each review in the Set reviews from the book object that I send back from the server. The result is seemingly a massive internal server error, I get a very long stack-trace printed out to the terminal, I have no idea what might be the problem. If I comment out the ul block, everything works fine.

The error (opens new link, pastebin) (not the full error, it did not fit in VSCODE terminal.

I've been trying to get this big text inside the placeholder to be indented inside the code only. But as I try to indent it, the code gets the indentation as literal inside the quotes.

I fear this is again a question about interpreting the ISO/IEC 14882 (the C++ standard) but:

Is calling main from the program e.g. my calling main() recursively from main not at least implementation defined behavior? (Update: I imply later ill-formed not implementation defined, also not UB, see below and answer)

6.9.3.1 [basic.start.main] states

3 The function main shall not be used within a program. The linkage (6.6) of main is implementation-defined...

The consensus seems to be undefined behavior (UB). The documentation of MSVC also points towards UB, the one of gcc also implicitly denies implementation-defined behavior. It can not be [defns.unspecified] unspecified behavior since I would interpret shall not as ill-formed.

However, despite the implementations, to my interpretation is should not be UB but as 4.1 [intro.compliance] states

1 The set of diagnosable rules consists of all syntactic and semantic rules in this document except for those rules containing an explicit notation that “no diagnostic is required” or which are described as resulting in “undefined behavior”. ... (2.2) — If a program contains a violation of any diagnosable rule or an occurrence of a construct described in this document as “conditionally-supported” when the implementation does not support that construct, a conforming implementation shall issue at least one diagnostic message.

For me the reasoning seems clear

1. calling main implies the program contains a violation of the rule of [basic.start.main]
2. [basic.start.main] does not state calling/use is UB or a diagnostic is not required
3. 1. is an element of "diagnosable rules" as per [intro.compliance]
4. [intro.compliance] 2.2 states violation of any diagnoseable rule must be issued at least one diagnostic message
5. Since 3. and 4. the usage of main shall issue at least one diagnostic message
6. Since 5. 1. is not UB
7. Since neither gcc,MSVC or clang issue an error or warning but compile, all major implementations are not compliant

Of course since 7. I feel again in the Don Quixote scenario i.e. being wrong, so I would appreciate if someone could enlighten me about my mistake. Otherwise, there are standard defects, aren't there?

I am using Groovy / XmlSlurper to read parent nodes of an XML document, for example the following program:

The regex I am using is \d+-\d+, but I'm not quite sure about how to separate the Roman numbers and how to create a new column with them.

I have this dataset:

My Mongoose requests have all been timing out since yesterday.

My internet connection is working well, the same as usual, and my source code is unchanged.

So, I think it must be a problem with my dependencies or with MongoDB itself.

Minimal reproducible example:

I am learning C# and I am trying to parse json/xml responses and check each and every key and value pair. For xml I am converting to json so I have only one function/script to work with both cases. My issue is that I am working with a wide range of json responses which are not similar and there may be arrays in some of the json response. I have tried accessing the "Count" of the json object as a way to check for arrays.

Note: The responses will vary. This example is for Products > Product > name, quantity and category. The next response will change and can be like Country > State > Cities and so on. I cannot rely on creating classes since all responses are going to be different. Plus I am working on automating it so it should be able to handle anything thrown at it.

Sample Json I am working with:

I am following this tutorial which secures my Blazor WebAssembly Apps with Auth2.com and I am using command line to run the program. I could completed all the steps successfully and I could the Blazor app. But for the last step, I got this error from the command line
