            Python typing: Retrieve required keys from TypedDict definition
            Asked 2022-Mar-14 at 06:18

            In Python3.10, I have a typing.TypedDict definition and want to programmatically retrieve which keys are required. How can I inspect the type definition in order to get the required keys?



            Answered 2022-Mar-13 at 23:54

            Taking PEP-655 into account, there are different scenarios: The whole TypedDict could have total=False or total=True, and individual fields could be marked as either Required or NotRequired. And there could also be the edge case where a TypedDict is inheriting from another, and one of them has total=False and the other one has total=True. In order to handle this edge case, Python introduced the __required_keys__ attribute on the TypedDict. This is what we have to look at:



            Android Studio - how to remove "Avoid lines longer than 80 characters" inspection alert

            I am using Android Studio, is there any way to disable this annoyed inspection.

            I tried to disable all inspection, invalidate cache and restart but still

            I found that there is lint configuration in the code, so just disable and the alert will gone.

            Expected type 'Type[Add | Sub | Mult | Div | Pow | BitXor | USub]', got 'Type[operator]' instead
            Asked 2022-Mar-05 at 00:22


            Answered 2022-Mar-05 at 00:22

            The type checker is warning you that your dictionary that maps AST node types for operators to their implementations is incomplete. The type checker knows all of the possible types of node.op (which it seems to be describing as subtypes of the ast.operator and ast.unaryop parent types), and has noticed that your dictionary doesn't handle them all.

            Since there are operators that you haven't included, it's possible for a parsable expression (like, say "2 << 5" which does a left shift, or "~31" which does a bitwise inversion) to fail to be handled by your code.

            While I don't use PyCharm and thus can't test it for myself, you can probably satisfy its type checker by adding some error handling to your code, so that operator types you don't support will still be dealt with appropriately, rather than causing an uncaught exception (such as a KeyError from the dictionary) to leak out. For instance, you could use OPERATORS.get(type(node.op)) and then test for None before calling the result. If the operator type isn't in the dictionary, you'd raise an exception of your own.



            How does Intellij code inspection decide on selectors from .css files?
            Asked 2022-Jan-21 at 10:17

            I have a css file in which there's a selector for class App-logo



            Answered 2022-Jan-21 at 10:17

            The IDE only looks for CSS selector usages in stylesheets and HTML files/fragments; it won't inspect plain text files and files of unknown type. I've just checked - CSS usages are correctly found in Velocity templates:

            Make sure to add *.vtl pattern to Velocity Template file type in Settings | Editor | File Types



            Android studio code inspection shell script for integration in CI pipeline
            Asked 2021-Oct-22 at 10:17

            I am trying to integrate dead code analysis for my android app to improve code quality. I found out the code inspection option that android studio provides out of the box which is giving me an extensive report of unused code and suggested improvements.

            I used the Analyze -> inspect code option

            I get the results in studio as follows:

            This is very useful but I want to integrate this code analysis into my CI pipeline so that I can track and trend the warnings that are reported.

            I found out a blog that said I can use the file that comes with the Android Studio package for the same purpose. The syntax of the command is as follows:



            Answered 2021-Oct-21 at 10:00

            It's because you didn't specify a parameter for the -d option.


            It should be like this:



            inspect.getargvalues returns keyword only args as args instead of varargs
            Asked 2021-Oct-08 at 16:01

            How can it be explained that inspect.getargvalues returns keyword only args as args instead of varargs. Is this a bug or a documentation bug? Are keyword only args not keyword args? I don't understand.


            Get information about arguments passed into a particular frame. A named tuple ArgInfo(args, varargs, keywords, locals) is returned. args is a list of the argument names. varargs and keywords are the names of the * and ** arguments or None. locals is the locals dictionary of the given frame.



            Answered 2021-Oct-08 at 16:01

            As it says: "varargs and keywords are the names of the * and ** arguments". Your function doesn't have any * or ** arguments.

            C26434 Function xxx hides a non-virtual function
            Asked 2021-Jul-28 at 15:55

            Take this simple code:



            Answered 2021-Jul-28 at 15:55

            C26434 warning documentation links to C.128 C++ Core Guidelines Rule. It explains that to enforce correct usage of virtual functions, non-virtual function hiding should produce a warning.

            However, with MFC message maps, you have to name your message handler as specified in macro, OnSize in this case, and, since message handlers already dispatched by a virtual function (that is hidden in *_MESSAGE_MAP() macros), message handler by themselves don't have to be virtual.

            So it may be seen as a false alarm. Or maybe seen as violation of the above mentioned C.128 rule by MFC itself. No surprise - MFC is decades older than these guidelines.

            So I guess you can go ahead and suppress it for all afx_msg functions. Maybe redefine afx_msg to include __pragma(warning(suppress(...))), or just have suppression around afx_msg block.

            Some options for suppression (Godbolt's compiler explorer demo):

            Unjustified "variable is possibly null" warning in WebStorm
            Asked 2020-Dec-17 at 13:54

            I like all the inspections in WebStorm, which help me clean up my code and find potential issues. But I fail to understand some warnings and they are getting into my way.

            For example in the screenshot below you can see that I explicitly check if the variable result is null, and if so, assign an empty array to it. However, just below that WebStorm gives me a warning that the variable result is possibly null.

            What is going on here? Do I have to clear a cache or is this simply a bug in WebStorm's inspections? Or am I missing something completely and the Warning is justified?

            Edit: If this is a bug, it might be helpful to know that the variable is explicitly set to null on declaration (let result = null;).

            How can I get the value of inheritance class of other inheritance class in .NET Roslyn API?
            Asked 2020-Oct-30 at 20:21

            Good day, I've been trying to get the value of inheritance class name of other inheritance class in Roslyn API.

            like below picture,

            when I'm scanning the 'Face' class, I want to get the name of "Human". like this structure, I can get the first inheritance class name by using ClassDeclaration.BaseList. I can get the name of "Head" from Face class!

            But I can't access the second inheritance class(Human class). I think that there's no more tree structure in Face class.

            The question point is that the way how to get 2-layer upper(or more) inheritance class name if in case of the classes are seperated.

            Thank you.



            Answered 2020-Oct-30 at 20:21

            Get the SemanticModel for your tree, then call GetDeclaredSymbol() with the ClassDeclarationSyntax. That'll give you the ITypeSymbol and you can look at BaseType from there. You don't want to try this with syntax only because of partial classes.
