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. Only with the help of macros can we write a generic container, which can compete with type-specific containers in efficiency after initialization.Kotlin/Native as a dynamic library – tutorial Since C language has no template feature, macros can only be used to achieve efficient paradigm programming. As a result, the source code is a bit difficult to read and not conducive to subsequent debugging. In order to use these data structures, we need to first expand the instance methods in the macro. In order to realize the paradigm of containers, klib makes extensive use of C macros. In order for me to understand better, I am able to read carefully through translation. Therefore, the first step in learning klib is to read its documentation.
Step 1: Read the documentationĪn excellent project will inevitably have an excellent document to introduce the project, otherwise it can only be used for self-entertainment and not widely used. For example, kindle reads like candle, so the k, function name, and structure name here are all acceptable Think it is c, which means this is a c language library.
Regarding the k in the name of klib, I thought of the previous English teacher saying that k and c are pronounced similarly in English. seqtk main use of the two header files, khash.h and kseq.h, and I found these two files klib, whereas klib provide a more detailed introduction to the document, so I went directly to the school klib. So for C language, how should I use an existing wheel?Ī few days ago, I translated a blog by Li Heng Dashen about the introduction of seqtk code, so I decided to use seqtk as the starting point to introduce how to use wheels made by others.
#Klib library python install#
For Python and R, use an existing tool, usually install it first, and then learn how to call the function by looking at the help document.
