Function Documentation

readArgs()

std::expected< Args, std::string > morph::client::readArgs ( std::vector< std::string > & args )

nodiscard

Reads the client's options from args and removes them, leaving the rest for the frontend.

Each value option is --name value or --name=value, and the last one given wins. args[0] is the program name, and nothing after a -- is read.

Parameters

args	The command line; what was read is removed.

Returns

The options, or why they are refused: a value option without its value, or not exactly one of --server and --app. args is unchanged on a refusal.
