language-interoperability

问题 I'm trying to interact with an old C terminal app from Swift. I've successfully integrated the source code and bridged the headers from C to Swift. The code compiles and runs from Xcode 6.3 beta. I've renamed the terminal app's main entry point to: int initialize(int argc, char **argv); Nevertheless, I'm struggling to pass the arguments from Swift to this C function. My challenge is to convert the arguments in the right format. Typical input from Swift would look like: let args = ["-c", "1.2

问题 I have an Objective-C class (that happens to be a button, but that is not important), and at another part of my (mixed language) project, I have an array of these buttons and I'd like to get the index of a button using the find() method. Like so: func doSomethingWithThisButtonIndex(index:Int) { let buttons = [firstButton, secondButton, thirdButton] if index == find(buttons, firstButton) { // we've selected the first button } } but I'm getting the Type 'ImplicitlyUnwrappedOptional' does not

问题 I recently played around a bit with different LLVM Frontends like Clang (C Familiy ), LDC2 (D), Terra, ... All these languages can be compiled into the LLVM IR (somewhat readable) and LLVM IR Bitcode . So at this stage they are all on the same "level" right? My Question is : Is there some way of language interoperability like the .NET Languages or JVM Languages on "language level" or is it only possible to do it by editing in the IR? I already looked this question up in Google but didn't find

问题 I am a Scala beginner and coming from Object Oriented Paradigm. While understanding Functional programming part of Scala, I was directed to Haskell - the pure Functional programming language. Exploring SO question-answers, I found that Java - Haskell has interoperability. I am curious to know that similarly does Scala-Haskell interoperability exist or not? Can a function library written in Haskell be used in Scala application? As per answer given by Don Stewart: It is possible. Integration of

问题 I started writing an application in Python, but I now want to switch to C# and UWP. I know that you cannot write a UWP app in Python, but I am trying to see if I can write some code in Python and access that code from C#. For example, writing a class in Python that C# code can access as well. Is that possible? And if so, can Python access Microsoft's UWP APIs? The main code will not be written in Python; that would be impossible. But can interoperability between C# and Python exist, perhaps

问题 I'm Using C# WPF. I have a C++ test dll as follow: .h: extern "C" __delspec(dllexport) void TestMethod(); .cpp file: extern "C" { __delspec(dllexport) void TestMethod() { MessageBox(0, L"Test", L"Test", MB_ICONINFORMATION); } } C# Code: [DllImport("DllTest.dll", EntryPoint = "TestMethod")] public static extern void TestMethod(); And when i'm trying to call to TestMethod i got exception: an attempt was made to load a program with an incorrect format What i'm doing wrong? Thanks! 回答1: This

问题 Can somebody tell me how should I unit-test extension functions in Kotlin? Since they are resolved statically should they be tested as static method calls or as non static ? Also since language is fully interoperable with Java, how Java unit test for Kotlin extension functions should be performed ? 回答1: Well, to test a method, whether static or not, you call it as real code would do, and you check that it does the right thing. Assuming this extension method, for example, is defined in the

问题 Quote from Defining JavaScript Resources In QML: Some JavaScript files act more like libraries - they provide a set of helper functions that take input and compute output, but never manipulate QML component instances directly. What if I want a JS file that both: manipulates QML component instances (that are passed to it as arguments) doesn't get a copy of its code and data stored for every QML component instance that imports it? I could get the "no data stored on every instance" part by, well

问题 I've got a project using the Swift generated Bridging Header and have the project set up correctly (no spaces in Names, Uses Modules, pre-declaring Swift classes in my .mm file, Deleting derived data, doing a clean rebuild etc...). The Bridging Header is being generated fine, but the automatically generated -Swift.h has errors in it. What's even worse, those errors are on the generated (in project creation - Swift) versions of AppDelegate and ViewController which would normally compile fine.
