#xdgpp
C++17 header-only implementation of the XDG Base Directory Specification.
#Installation
Copy xdg.hpp into your source tree.
#Usage
#include <iostream>
#include "xdg.hpp"
int main() {
std::cout << "$XDG_DATA_HOME = " << xdg::DataHomeDir() << std::endl;
std::cout << "$XDG_CONFIG_HOME = " << xdg::ConfigHomeDir() << std::endl;
std::cout << "$XDG_CACHE_HOME = " << xdg::CacheHomeDir() << std::endl;
auto data_dirs = xdg::DataDirs();
std::cout << "$XDG_DATA_DIRS = \"" << data_dirs.front().c_str();
for (int i = 1; i < data_dirs.size(); i++) {
std::cout << ":" << data_dirs.at(i).c_str();
}
std::cout << "\"" << std::endl;
auto config_dirs = xdg::ConfigDirs();
std::cout << "$XDG_CONFIG_DIRS = \"" << config_dirs.front().c_str();
for (int i = 1; i < config_dirs.size(); i++) {
std::cout << ":" << config_dirs.at(i).c_str();
}
std::cout << "\"" << std::endl;
// XDG_RUNTIME_DIR might not be set, the API returns a std::optional
auto runtime_dir = xdg::RuntimeDir();
if (runtime_dir) {
std::cout << "$XDG_RUNTIME_DIR = " << runtime_dir.value();
}
return 0;
}
Alternatively you can create and use an instance of xdg::BaseDirectories like:
#include <iostream>
#include "xdg.hpp"
int main() {
xdg::BaseDirectories dirs;
std::cout << "$XDG_DATA_HOME = " << dirs.DataHome() << std::endl;
}
