There is a constructor in the Clazz field (aka .Clazz), which is the constructor function to create an instance of the Clazz. The C language does not support objects, and this is the reason to pass a this pointer explicitly. The only difference is that the memberFunction accepts a this reference as the first parameter. The Clazz#memberFunction is accessible with the memberFunction field. There is a field that represents the Clazz from Kotlin.

Let's take a look at the field, it mimics the package structure of our Kotlin code with a kotlin.root. Also, there is the tutorial Kotlin/Native as an Apple Framework. The Objective-C Interop documentation article contains more details on it. Kotlin/Native has interop with Objective-C and Swift and integrates with their reference counters. Kotlin/Native has garbage collection, but it does not help us deal with Kotlin objects from the C language. The actual set of operations generated depends on the actual usages. It is possible to use the IsInstance function to check if a Kotlin type or a libnative_KNativePtr is an instance of another type. Call the DisposeStablePointer to release a Kotlin object and DisposeString to release a Kotlin String, which has the char* type in C. These functions deal with Kotlin/Native objects. Libnative_KBoolean (*IsInstance)(libnative_KNativePtr ref, const libnative_KType* type) Void (*DisposeString)(const char* string) Void (*DisposeStablePointer)(libnative_KNativePtr ptr) The libnative_ExportedSymbols structure contains several helper functions: The libnative_ prefix comes from the library name.

It uses nested anonymous structures heavily to mimic packages. You have the libnative_ExportedSymbols structure, which defines all the functions that Kotlin/Native and our library provides us. It is tricky to read, but we should be able to see function pointer fields in the structures above. A function pointer is declared as follows RETURN_TYPE (* FIELD_NAME)(PARAMETERS). People use function pointers to mimic object semantics. Start by creating a library file in Kotlin and save it as hello.kt:įun forIntegers(b: Byte, s: Short, i: UInt, l: Long) foo declares a field in the outer struct of that anonymous structure type, the type with no name.Ĭ does not support objects either. First, create a first tiny Kotlin library and use it from a C program. The best way to understand these techniques is to try them out. h file, which you will use to call the compiled code from C. A dynamic library often comes with a header file, a. Kotlin/Native compiler can produce a dynamic library out of the Kotlin code.

The Kotlin/Native as an Apple Framework tutorial explains how to compile Kotlin code into a framework for Swift and Objective-C.Ĭompile and run the example on Linux and Mac and Windows Kotlin/Native also has tight integration with Apple technologies. For this, you need to compile the Kotlin code into a dynamic library. Learn how you can use the Kotlin/Native code from existing native applications or libraries. Now, after installing the library, the program is working.Kotlin/Native as a dynamic library – tutorial Re-importing: > from bs4 import BeautifulSoup Successfully installed beautifulsoup4-4.9.3 Installing collected packages: beautifulsoup4

Requirement already satisfied: soupsieve>1.2 python_version >= '3.0' in /home/py/Desktop/seo_pro/seo_env/lib/python3.6/site-packages (from beautifulsoup4) (1.9.5)

Now, let's install the library and try to re-import it ModuleNotFoundError: No module named 'bs4' So before importing a library's module, you need to install it with the pip command.įor example, let's try to import the Beautifulsoup4 library that's not installed in my virtual environment. Output: ModuleNotFoundError: No module named 'module'Īs you can see, we have imported the module successfullyĪlso, you can get the issue if you are trying to import a module of a library which not installed in your virtual environment. The Second reason is Probably you would want to import a module file, but this module is not in the same directory. ModuleNotFoundError: No module named 'oss'Īs you can see, we got No module named 'oss'. The first reason of this error is the name of the module is incorrect, so you have to check out the module name that you had imported.įor example, let's try to import os module with double s and see what will happen: > import oss
