set_pushover_app() sets the Pushover application token to be used in
subsequent commands, get_pushover_app() gets the application token
that is currently set, and unset_pushover_app() unsets the token.
set_pushover_app(token = NULL, ask = is_interactive()) get_pushover_app(ask = is_interactive()) unset_pushover_app()
| token | The application token to be used. If none is provided, a prompt will request the token (interactive sessions only).  | 
    
|---|---|
| ask | Whether or not to ask for the token if none is provided. Note that this option only works in interactive sessions.  | 
    
get_pushover_app() returns a string containing the current
application token. If the token is not set but ask is TRUE,
the user will be prompted for a token.
set_pushover_app() only sets the Pushover app token for the current
session. If a different value is specified in .Renviron, that value will be
used in future sessions. Similarly, unset_pushover_app() will only
unset the app token for the current session.
To receive an application token, register a new application after logging in to your account at https://pushover.net/apps.
