Detailed Description

An implementation of the Telnet Environment option.

Overview: NEW-ENVIRON is used to send the values of variables from server to client.

: Variables are transmitted in pairs of telnetpp::options::new_environ::request and telnetpp::options::new_environ::response, where the request is the type of the variable (either a well known "var" type, the names of which are limited – see the specification), or a "uservar" type, which could have any name. The response may also contain a string if the variable existed.

Usage: Create a server or client as appropriate. Install it in a session, activate as normal.

: A client may make a request of the server by calling request_variables(). It may also register for notifications about responses by subscribing to the on_variable_changed signal.

: A server may set or delete variables and user variables, and will automatically handle requests sent from a client by using this data.
