oauth_app_from_json() is being replaced with gargle_oauth_client_from_json(), in light of the new gargle_oauth_client class. Now oauth_app_from_json() potentially warns about this deprecation and immediately passes its inputs through to gargle_oauth_client_from_json().

gargle_app() is being replaced with gargle_client().

## Usage

oauth_app_from_json(path, appname = NULL)

gargle_app()

## Arguments

path

JSON downloaded from Google Cloud Console, containing a client id and secret, in one of the forms supported for the txt argument of jsonlite::fromJSON() (typically, a file path or JSON string).

appname

name of the application. This is not used for OAuth, but is used to make it easier to identify different applications.
