cross-platform

问题 This answer specifies how to do this. It is also my understanding that <sys/stat.h> is only available on POSIX, whereas any operating system worth using supports <stdio.h> . Is there a cross platform way to check if a path-specified object is a file or directory in C? 来源： https://stackoverflow.com/questions/62312279/is-there-a-cross-platform-way-to-check-if-an-object-specified-in-a-path-is-a-dir

问题 I have an assets folder in which I have a tab folder and then a list of folders and each folder contains some files Now I want to read the names of all the folders that are in the tabs folder and all the files that are in each subfolder of the tabs folder, i.e. folders that are named as sound 1, sound 2, sound 3 ..... In simple words, I want to read names of all files and folders that are in my assets folder. Please Anyone help. Thanks, 回答1: Even if you specified only asset folders in pubspec

问题 I'm new in programming. From what i know, a program that is compiled in Linux should not be able to run in Windows. So, if we want to run the same program in both platform, we need to compile the source code under both platform, and create 2 different executable files. Recently I am studying the source code of an open source, cross-platform Java GUI application. I'm surprised to find that the backend engine of that GUI application is a small executable file generated from C++ codes. No matter

问题 I am looking for two fitting code snippets to encode some text with python, which is to be decoded in php. I am looking for something "easy" and compatible, and I have not much encryption experience myself. If someone could give a working example that would be great! 回答1: python encrypt from Crypto.Cipher import AES import base64 import os # the block size for the cipher object; must be 16, 24, or 32 for AES BLOCK_SIZE = 32 BLOCK_SZ = 14 # the character used for padding--with a block cipher

问题 I am looking for an efficient and smart way to send data between a C++-program and a Python-script. I have a C++ program which calculates some coordinates in-real-time 30Hz. And I wanna access these coordinates with a Python-script. My first idea was to simply create a .txt-file and write the coordinates to it, and then have Python open the file and read. But I figured that it must be a smarter and more efficient way using the RAM and not the harddrive. Does anyone have any good solutions for

问题 How can one detect the OS type using Rust? I need to specify a default path specific to the OS. Should one use conditional compilation? For example: #[cfg(target_os = "macos")] static DEFAULT_PATH: &str = "path2"; #[cfg(target_os = "linux")] static DEFAULT_PATH: &str = "path0"; #[cfg(target_os = "windows")] static DEFAULT_PATH: &str = "path1"; 回答1: You can also use cfg! syntax extension. if cfg!(windows) { println!("this is windows"); } else if cfg!(unix) { println!("this is unix alike"); }

问题 Background: We are in the process of migrating .Net application to .Net Core. As a strategy, we would like to keep the existing functionality intact on Full framework while migrating portion of the application to .Net Core. Full application would support .services over Net remoting and REST API whereas .Net core application will only support REST API services. We have decided to keep the same code base for entire application and support compilation on multiple platforms (NetcoreApp2.1 and

问题 I want to write a script that will execute on Linux and Solaris. Most of the logic will be identical on both OS, therefore I write just one script. But because some deployed structure will differ (file locations, file formats, syntax of commands), a couple of functions will be different on the two platforms. This could be dealt with like if 'linux' in sys.platform: result = do_stuff_linux() if 'sun' in sys.platform: result = do_stuff_solaris() more_stuf(result) ... However it seems to

问题 Is it possible to differentiate between operating systems in C# using preprocessor ? like : #if OS_WINDOWS //windows methods #elif OS_MAC //mac methods #elif OS_LINUX //linux methods #endif 回答1: What you are asking for is possible but needs a bit of work. Define a preprocessor variable in your csproj <PropertyGroup Condition=" '$(OS)' == 'Windows_NT' "> <DefineConstants>_WINDOWS</DefineConstants> </PropertyGroup> Use that in your code #if _WINDOWS // your windows stuff #else // your *nix
