A CSV file is a list of strings separated by commas, with newlines (\n) separating the rows.

Due to this simplistic layout, it is often not suitable for containing strings that may contain commas within them, for instance dialogue.

That being said, with your input file, it is possible to use regex to replace any single newlines with a comma, which effectively does the "each new line converted into a column, each new paragraph a new row" requirement.

Basically, you seem to want lag(ignore nulls) -- the most recent non-NULL value. SQL Server does not support this standard functions.

One method instead is to assign groups by counting the number of non-NULL values up to each row and then use window functions:

^[a-zA-Z]*$ Match at least 0 or more of lowercase/uppercase letters from beginning to the end. a+C+a+2+3 does not satisfy those requirements but an empty string does.
^[0-9|*|+|/|-]*$ Match at least 0 or more of digits, *, +, / or - from beginning to the end; thus will match 1+2/33*4 and an empty string too.

So, this might be the pattern you're looking for:

You can't quite do this without an extra subquery, but you can avoid querying the same table again and again.

All you need to do, is to get the data into a single XML blob in one subquery, then query it back out in each of the other subqueries:

QUESTION

Xcode error 'building for iOS Simulator, but linking in dylib built for iOS .. for architecture arm64' from Apple Silicon M1 Mac

Asked 2021-Jun-14 at 09:55

I have an app which compiles and runs fine in older Macs with Intel processors in physical devices & iOS simulators.

The same app also compiles and runs fine from newer Apple Silicon Mac with M1 processor with physical iPhone devices, but, it refuse to be compiled for iOS simulator.

Without simulator support, debugging turn around time gets gets really long so I am trying to solve this issue. Not to mention Xcode preview feature isn't working either which is annoying.

The first error that I encountered without making any changes (but moved from Intel Mac to M1 Mac) is like below.

building for iOS Simulator, but linking in dylib built for iOS, file '/Users/andy/workspace/app/Pods/GoogleWebRTC/Frameworks/frameworks/WebRTC.framework/WebRTC' for architecture arm64

The Cocoapods library that I am using is GoogleWebRTC, and according to its doc, arm64 should be supported so I am baffled why above error is getting thrown. As I have said before, it compiles fine in real device which I believe is running on arm64.

According to the doc..

This pod contains the WebRTC iOS SDK in binary form. It is a dynamic library that contains the armv7, arm64 and x86_64 slices. Bitcode is not supported. Our currently provided API’s are Objective C only.

I searched online and it appears there appears to be 2 workarounds for this issue.

The first one is by adding arm64 to Excluded Architectures
The second option is to mark Build Active Architecture Only for Release build.

I don't exactly understand if above are necessary even when I am compiling my app on M1 Mac which is running under arm64 architecture, because the solution seems to be applicable only for for Intel Mac which does not support arm64 simulator, as for Intel Mac, simulators might have been running in x86_64, not with arm64, so solution #1 is not applicable in my case.

When I adapt the second change only, nothing really changes and the same error is thrown.

When I make both changes and tried building, I now get the following 2nd error during build. (not really 100% sure if I solved the 1st error / I might have introduced 2nd error in addition to 1st by adapting two changes)

Could not find module 'Lottie' for target 'x86_64-apple-ios-simulator'; found: arm64, arm64-apple-ios-simulator

The second library that I am using is lottie-ios and I am pulling this in with a swift package manager. I guess what is happening is that because I excluded arm64 in build setting for iOS simulator, Xcode is attempting to run my app in x86_64. However, library is not supported running in x86_64 for some reason, and is throwing an error. I don't have much insights into what dictates whether or not library can run in x86_64 or arm64 so I couldn't dig to investigate this issue.

My weak conclusion is that GoogleWebRTC cannot be compiled to run in iOS simulator with arm64 for some reason (unlike what its doc says), and lottie-ios cannot be compiled to run in iOS simulator with x86_64. So I cannot use them both in this case.

Q1. I want to know what kind of changes I can make to resolve this issue...

The app compiles and runs perfectly in both device & simulator when compiled from Intel Mac. The app compiles and runs fine in device when compiled from Apple Silicon Mac. It is just that app refuse to be compiled and run in iOS simulator from Apple Silicon Mac, and I cannot seem to figure out why.

Q2. If there is no solution available, I want to understand why this is happening in the first place.

I really wish not to buy old Intel Mac again just to make things work in simulator.

ANSWER

Answered 2021-Mar-27 at 20:15

Answering my own question in a hope to help others who are having similar problems. (and until a good answer is added from another user)

I found out that GoogleWebRTC actually requires its source to be compiled with x64 based on its source depo.

For builds targeting iOS devices, this should be set to either "arm" or "arm64", depending on the architecture of the device. For builds to run in the simulator, this should be set to "x64".

https://webrtc.github.io/webrtc-org/native-code/ios/

This must be why I was getting the following error.

building for iOS Simulator, but linking in dylib built for iOS, file '/Users/andy/workspace/app/Pods/GoogleWebRTC/Frameworks/frameworks/WebRTC.framework/WebRTC' for architecture arm64

Please correct me if I am wrong, but by default, it seems that Xcode running in Apple M1 silicon seems to launch iOS simulator with arm arch type. Since my app did run fine on simulators in Intel Mac, I did the following as a workaround for now.

Quit Xcode.
Go to Finder and open Application Folder.
Right click on Xcode application, select Get Info
In the "Xcode Info Window" check on Open using Rosetta.
Open Xcode and try running again.

That was all I needed to do to make my app, which relies on a library that is not yet fully supported on arm simulator, work again. (I believe launching Xcode in Rosetta mode runs simulator in x86 as well..?? which explains why things are working after making the above change)

A lot of online sources (often posted before M1 Mac launch on Nov/2020) talks about "add arm64 to Excluded Architectures", but that solution seems to be only applicable to Intel Mac, and not M1 Mac, as I did not need to make that change to make things work again.

Of course, running Xcode in Rosetta mode is not a permanent solution, and Xcode slows down lil bit, but it is an interim solution that gets things going in case one of libraries that you are using is not runnable in arm64 simulator.. yet.

So I had to include this part in one of our class projects. We were asked to create a quiz webpage with radios and checkboxes, and then to write a JavaScript function to validate the radios. Now, I know that these radios can be verified easily by individuals for loops for each group, but that doesn't sound practical when I have a large number of these groups in my code. So I tried the following code:-

ANSWER

Answered 2021-Jun-14 at 04:49

You never set check to true anywhere, so it is always false.
radiob[i] is an array (or, more precisely, a NodeList), so radiob[i].checked is always undefined.
Arrays in JavaScript start indexing at 0, and this applies to NodeList as well. So your for (var j = 1; j <= radiob[i].length; j++) loop is not correct.

If you fix these problems then your function should work correctly.
