QUESTION
I'm working on a CLI tool. I used "commander", which is a CommonJS module, to parse command-line arguments. I also want to use "p-map" to manage concurrency. However, "p-map" is a ES6 module.
Also I'm using Typescript.
Now both code editor and Typescript compiler won't complain. However I cannot execute my CLI tool. If I compile with "module":"commonjs", node would not load p-map and complains "Must use import to load ES Module... node_modules/p-map/index.js...require() of ES modules is not supported.". If I compile with "module":"es2015", use "require" to import the CommonJS modules, and add "type":"module" in my package.json, node would complain "ReferenceError: require is not defined".
I love the flexibility of Typescript/Javascript, however, it's time like this makes me miss Java. Java might be too prissy, but I don't spend hours trying to figure out import / export......
So, is it possible to use both CommonJS and ES6 module in a Node.JS command-line program?
...ANSWER
Answered 2021-Jun-05 at 12:42To enhance compatibility, the (moderately new) node esm loader can import cjs-modules (e.g. import identifier from 'cjs-module-name';).
The other way around doesn't work, you can't require an esm-module, but dynamic import should work, if really necessary.
A related read may be the statement from p-map's owner regarding the topic.
QUESTION
I would like to read Android/data so I can extract documents for backup purposes. Android 11 has changes that prohibit/limit this, but is it still possible? I don't want to use the legacy-approach (if possible).
According to this Manage all files on a storage device which talks about the MANAGE_EXTERNAL_STORAGE permission it seems Google claims it should now be impossible (at least with this method):
Apps that are granted this permission still cannot access the app-specific directories that belong to other apps because these directories appear as subdirectories of Android/data/ on a storage volume.
https://developer.android.com/training/data-storage/manage-all-files https://developer.android.com/about/versions/11/privacy/storage#other-apps-data
Here storage#other-apps-data Google also says that apps can no longer access other apps Android/data
Access to app-specific directories on external storage On Android 11, apps can no longer access files in any other app's dedicated, app-specific directory within external storage.
Here on stackoveflow Thoryia shows us how to ask for the permission.
But can we use it (or any other method) to read those forbidden other app-data folders, Android/data/* ?
The Android app 'Total Commander' does it (on Android 11), and it seems to be using the StorageAccessFramework Intent Intent.ACTION_OPEN_DOCUMENT_TREE to access the files (a guess based on the gui that pops up), but I havn't managed to figure out how to get that working either. Its possible Total Commander use a legacy-approach.
Pr request I've screenshots of Total Comander (TC) here on my OneDrive.
I strongly suspect TC just uses the target-29 access method, I found a list of its permissions here but cannot find which version it targets: Aptoide: TC v3.21

ANSWER
Answered 2021-May-28 at 20:14You're setting var livrs_pos = livrs[i].Location inside your for loop. Then you're trying to pass livrs_pos to geolib.orderByDistance (second argument). At this point, livrs_pos does not appear to be an array, which fails internally to geolib because orderByDistance calls .slice() on that array. Hence, n.slice is not a function, because n is not an array.
It looks like livrs[i].Location is an object instead. I think you should declare var livrs_pos = []; above your for loop. Then inside the loop do livrs_pos.push(livrs[i].Location);
QUESTION
Edit: others have responded showing xslt as a better solution for the simple problem I have posted here. I have deleted my answer for now.
I've been through about a dozen StackOverflow posts trying to understand how to import an XML document that has namespaces, modify it, and then write it without changing the namespaces. I discovered a few things that weren't clear or had conflicting information. Having finally got it to work I want to record what I learned hoping it helps someone else equally confused. I will put the question here and the answer in a response.
The question: given the sample XML data in the Python docs how do I navigate the tree without having to explicitly include the name-space URIs in the xpaths for findall and write it back out with the namespace prefixes preserved. The example code in the doc does not give the full solution.
Here is the XML data:

QUESTION
This is my parent class with two methods named toString. The one with the parameter is used in the child class.
ANSWER
Answered 2021-May-21 at 09:55In Your PanzerArmy.toString() you call Army.toString(String), which in turn calls toString(). You might expect Army.toString() to be executed here, but since you overrode it in PanzerArmy (and the current object is of type PanzerArmy) it will call PanzerArmy.toString(). .. which will call Army.toString(String) and start the whole jazz again, in a never ending recursion. Eventually the JDK decides that it's got enough of this and bails.
A better solution would be to make the toString() in Army abstract and only implement toString(String).
Alternatively you could use something like getClass().getSimpleName() to get the short name of the current class and immediately use that instead of having to tweak toString() for each subclass.
