NAH - Native Application Host

NAH standardizes how native applications are installed, inspected, and launched. It provides a deterministic contract between applications and hosts.

Quick Start

#include <nah/nah.h>
 
// Create a host instance
auto host = nah::NahHost::create("/nah");
 
// List installed applications
for (const auto& app : host->listApplications()) {
    std::cout << app.id << "@" << app.version << "\n";
}
 
// Get launch contract for an app
auto result = host->getLaunchContract("com.example.myapp");
if (result.isOk()) {
    const auto& contract = result.value().contract;
    // Use contract.execution.binary, contract.environment, etc.
}
