ProcessSettings

Properties

• WorkingDirectory() / setter
• CommandLine() / setter
• EnvironmentVariables() / setter
• OutputMode() / setter
• EnableStandardInput() / setter

Important notes

• CommandLine(nullptr) and EnvironmentVariables(nullptr) are rejected.
• Process::Start() later requires a non-empty CommandLine().
• ProcessOutputMode::Event installs C callbacks; ProcessOutputMode::Stream expects stream access; Discard is the default.
• EnableStandardInput() defaults to false. Must be set before Process::Start() or Session::CreateContainer() to have effect.

using namespace winrt::Windows::Foundation::Collections;

ProcessSettings procSettings;
procSettings.WorkingDirectory(L"/workspace");
procSettings.OutputMode(ProcessOutputMode::Event);

auto cmd = single_threaded_vector<hstring>();
cmd.Append(L"/bin/sh");
cmd.Append(L"-lc");
cmd.Append(L"echo hello");
procSettings.CommandLine(cmd);

auto env = single_threaded_map<hstring, hstring>();
env.Insert(L"DEMO", L"1");
procSettings.EnvironmentVariables(env);
