Sub is a model for setting up shell programs that use subcommands, like git or rbenv using bash. Making a sub does not require you to write shell scripts in bash, you can write subcommands in any scripting language you prefer.

QUESTION
I'm trying to build a project in my M1,
but I got this error when I run npx react-native run-android
ANSWER
Answered 2021-Sep-02 at 23:03The error is being caused because one of your dependencies is internally using WorkManager 2.7.0-beta01 that was released today (which needs API 31). In my case it was CheckAarMetadata.kt
.
You can fix it by forcing Gradle to use an older version of Work Manager for the transitive dependency that works with API 30. In your build.gradle
file add:
QUESTION
I've built my React Native app and tested and troubleshooted with my iOS devices for months. Now I'm trying to built and test the app on Android for the first time. The thing is, that I keep getting errors trying to run the Android-version of my app. After hours of debugging and troubleshooting, I tried to create a new RN project and see if that could run on my emulator and device. I got that part working and then I wanted to copy/paste the files of my existing app project into the new project.
I pasted my existing assets, styles, the source JS-files and the package.json file into the new project, ran npm install
and then I ended up with the exact same error message as I had in the original project when I run react-native run-android
.
The full error message is here:
...ANSWER
Answered 2021-Aug-21 at 13:43I've hit this same issue and have temporarily resolved it by uninstalling react-native-video (npm uninstall --save react-native-video). That's not a great answer as I need that component, but I don't have a full solution yet. I think somehow com.yqritc:android-scalablevideoview:1.0.4. is required by react-native-video but has gotten lost or removed. Other thoughts are welcome.
UPDATE: Resolved! In your build.gradle in your Android folder you need to add the repository "jcenter()" in allprojects (not in build dependencies) like this...

Answered 2021-Aug-04 at 09:18I'm not sure what you're using to code, but in order to set it in Android Studio, open the manifest of your project and under the "activity" section, put android:exported="true"(or false if that is what you prefer). I have attached an example.
QUESTION
I need to calculate the square root of some numbers, for example √9 = 3
and √2 = 1.4142
. How can I do it in Python?
The inputs will probably be all positive integers, and relatively small (say less than a billion), but just in case they're not, is there anything that might break?

The math
module from the standard library has a sqrt
function to calculate the square root of a number. It takes any type that can be converted to float
(which includes int
) as an argument and returns a float

ANSWER
Answered 2022-Jan-31 at 23:38The functions provided in the Python re
module do not optimize based on anchors. In particular, functions that try to apply a regex at every position - .search
, .sub
, .findall
etc. - will do so even when the regex can only possibly match at the beginning. I.e., even without multi-line mode specified, such that ^
can only match at the beginning of the string, the call is not re-routed internally. Thus:

QUESTION
After Android Studio upgraded itself to version Arctic Fox, I now get these strange sub-windows in my code editor that I can't get rid of. If I click in either of the 2 sub-windows (a one-line window at the top or a 5-line window underneath it (see pic below), it scrolls to the code in question and the sub-windows disappear. But as soon as I navigate away from that code, these sub-windows mysteriously reappear. I can't figure out how to get rid of this.
I restarted Studio and it seemed to go away. Then I refactored a piece of code (Extract to Method Ctrl+Alt+M) and then these windows appeared again. Sometimes these windows appear on a 2nd monitor instead of on top of the code area on the monitor with Android Studio. But eventually they end up back on top of my code editor window.
I have searched hi and low for what this is. Studio help, new features, blog, etc. I am sure that I am just using the wrong terminology to find the answer, so hoping someone else knows.
...ANSWER
Answered 2021-Aug-15 at 15:29Just stumbled upon the same thing (strange windows upon attempting to refactor some code after updating to Arctic Fox). After a lot of searching around the options/menus/internet this fixed it for me:
Navigate to:
File > Settings... > Editor > Code Editing
under
Refactorings > Specify refactoring options:
select
In modal dialogs
Press OK.
Fingers crossed refactoring works.
🤞
Further step: Restart Android Studio
QUESTION
I have the following code:
...ANSWER
Answered 2022-Jan-01 at 07:32Given x.f(1.01);
, the name f
is found in the scope of class Sub
, then name lookup stops; the scope of Abs
won't be examined. Only Sub::f
is put in overload set and then overload resolution is performed.
... name lookup examines the scopes as described below, until it finds at least one declaration of any kind, at which time the lookup stops and no further scopes are examined.
You can use using
to introduce the names of Abs
into Sub
, then Abs::f
could be found and take part in overload resolution too.
QUESTION
I created an extension method to add all JSON configuration files to the IConfigurationBuilder
ANSWER
Answered 2021-Dec-19 at 09:24The logic of comparing files seems alright, I don't find any outstanding problem with it, it is ok to prepend the "/" to match what you need.
Could be even better if you could use the System.IO.Path.DirectorySeparatorChar
for the directory root path as well, so if you run on windows or Linux you will have no issues.
But there may be a conceptual problem with what you are doing. To my understanding you aim to verify existence of specific configuration files required for your program to work right, if those files are missing than the program should fail. But that kind of failure due to missing configuration files, is an expected and valid result of your code. Yet, you unit-test this as if missing files should fail the test, as if missing files are an indication that something wrong with your code, this is wrong.
Missing files are not indication of your code not working correct and Unit-test should not be used as a validator to make sure the files exist prior executing the program, you will likely agree that unit-test is not part of the actual process and it should only aim to test your code and not preconditions, the test should compare an expected result (mock result of your code) vs. actual result and certainly not meant to become part of the code. That unit test looks like a validator that should be in the code.
So unless those files are produced by your specific code (and not the deployment) there is no sense testing that. In such case you need to create a configuration validator code - and your unit test could test that instead. So it will test that the validator expected result with a mock input you provide. But the thing here is that you would know that you only testing the validation logic and not the actual existence of the files.
