Run shell commands from C++. Also a simple subprocess module for running commands asynchronously.
cout << cmd{"ls -l"} << endl;
Outputs whatever ls -l outputs. To get the results as a string:
string user = cmd{"whoami"}.str();
cout << "Username: " << user << endl;
The default behavior is for a command to throw an exception if it fails. See demo.cpp for more examples.
cppshell::subprocess proc{"ls","-l"};
This call will return immediatly, having started the command in a separate thread. You can now read from it's stdout, by getting its file descriptor: proc.stdout() (no support for writing back to it yet - that just requires another pipe).
Reading "everything" from the subprocess:
cout << proc << endl;
