# PlatformFolders [](https://travis-ci.org/sago007/PlatformFolders) [](https://raw.githubusercontent.com/sago007/PlatformFolders/master/LICENSE) A C++ library to look for special directories like "My Documents" and "%APPDATA%" so that you do not need to write Linux, Windows or Mac OS X specific code Can be found at: https://github.com/sago007/PlatformFolders Releases can be downloaded here: https://github.com/sago007/PlatformFolders/releases # Rationale There are a lot of platform abstraction libraries available. You can get graphics abstraction libraries, GUI abstraction libraries and file abstraction libraries. But folder abstraction seems to be more difficult. My problem was that the code that found the place to save data was platform dependent. This cluttered my code and often I would not discover that it did not compile until moving it to the different platforms. I have written a bit more about it here: http://sago007.blogspot.dk/2015/10/abstraction-for-special-folders.html There are some alternatives that you might consider instead: * QStandardPaths - http://doc.qt.io/qt-5/qstandardpaths.html * glib - https://developer.gnome.org/glib/stable/glib-Miscellaneous-Utility-Functions.html Both are properly more mature than this library. However they are both parts of large frameworks and using them with libraries outside the framework may not be that simple. # Windows support For Windows the folders are fetched using SHGetFolderPath. The amount of supported folders differ from Windows version and this library targets XP and newer... and I'll drop XP support very soon. Currently "Save Games" and "Downloads" should not be used as they are undefined on XP. # Linux support In Linux a lot of these folders are not official defined. However this library uses XDG user dirs. # Mac OS X support Uses the deprecated FSFindFolder (there is no C++ alternative). It requires "-framework CoreServices" during linking. # Usage Copy "sago/platform_files.cpp" and "sago/platform_fildes.h" to your program and make sure that the cpp file is compiled and linked. # Hello World This sample program gets all folders from the system: ``` #include <iostream> #include "sago/platform_folders.h" using std::cout; int main() { cout << "Config: " << sago::getConfigHome() << "\n"; cout << "Data: " << sago::getDataHome() << "\n"; cout << "Cache: " << sago::getCacheDir() << "\n"; sago::PlatformFolders p; cout << "Documents: " << p.getDocumentsFolder() << "\n"; cout << "Desktop: " << p.getDesktopFolder() << "\n"; cout << "Pictures: " << p.getPicturesFolder() << "\n"; cout << "Music: " << p.getMusicFolder() << "\n"; cout << "Video: " << p.getVideoFolder() << "\n"; cout << "Download: " << p.getDownloadFolder1() << "\n"; cout << "Save Games 1: " << p.getSaveGamesFolder1() << "\n"; return 0; } ``` The output on Linux would look like this: ``` Config: /home/poul/.config Data: /home/poul/.local/share Cache: /home/poul/.cache Documents: /home/poul/Dokumenter Desktop: /home/poul/Skrivebord Pictures: /home/poul/Billeder Music: /home/poul/Musik Video: /home/poul/Videoklip Download: /home/poul/Hentede filer Save Games 1: /home/poul/.local/share ``` On Windows it could be: ``` Config: C:\users\poul\Application Data Data: C:\users\poul\Application Data Cache: C:\users\poul\Local Settings\Application Data Documents: C:\users\poul\Mine dokumenter Desktop: C:\users\poul\Skrivebord Pictures: C:\users\poul\Mine Billeder Music: C:\users\poul\Min Musik Video: C:\users\poul\Mine Film Download: C:\users\poul\Skrivebord Save Games 1: C:\users\poul\Mine dokumenter\My Games ``` On Mac OS X it could be: ``` Config: /Users/poul/Library/Application Support Data: /Users/poul/Library/Application Support Cache: /Users/poul/Library/Caches Documents: /Users/poul/Documents Desktop: /Users/poul/Desktop Pictures: /Users/poul/Pictures Music: /Users/poul/Music Video: /Users/poul/Movies Download: /Users/poul/Downloads Save Games 1: /Users/poul/Library/Application Support ``` # Encoding From version 3.0 UTF-8 is always used on Windows and will also be the default in almost any other system. Before version 3.0 Windows used ANSI encoding. Microsoft's default choice of UTF-16 is not compatible with platform independent code. Although the user may use an charectors they want I recommend, that the progran should not have non ASCII charectors in the soruce code itself. # Licence Provided under the MIT license for the same reason XDG is licenced under it. So that you can quickly copy-paste the methods you need or just include the "sago"-folder.
