Wrapper functions around options consulted by gargle, which provide:
A place to hang documentation.
The mechanism for setting a default.
If the built-in defaults don't suit you, set one or more of these options.
Typically, this is done in the .Rprofile
startup file, with code along
these lines:
options( gargle_oauth_email = "jane@example.com", gargle_oauth_cache = "/path/to/folder/that/does/not/sync/to/cloud" )
gargle_oauth_email()gargle_oob_default()
gargle_oauth_cache()
gargle_quiet()
gargle_oauth_email()
returns the option named "gargle_oauth_email", which
is undefined by default. If set, this option should be one of:
An actual email address corresponding to your preferred Google identity.
Example:janedoe@gmail.com
.
TRUE
to allow email and OAuth token auto-discovery, if exactly one
suitable token is found in the cache.
FALSE
or NA
to force the OAuth dance in the browser.
gargle_oob_default()
returns the option named "gargle_oob_default", falls
back to the option named "httr_oob_default", and eventually defaults to
FALSE
. This controls whether to prefer "out of band" authentication. This
is ultimately passed to httr::init_oauth2.0()
as use_oob
. If FALSE
(and
httpuv is installed), a local webserver is used for the OAuth dance.
Otherwise, user gets a URL and prompt for a validation code.
Read more about "out of band" authentication in the vignette Auth when using R in the browser.
gargle_oauth_cache()
returns the option named "gargle_oauth_cache",
defaulting to NA
. If defined, the option must be set to a logical value or
a string. TRUE
means to cache using the default user-level cache file,
~/.R/gargle/gargle-oauth
, FALSE
means don't cache, and NA
means to
guess using some sensible heuristics.
gargle_quiet()
returns the option named "gargle_quiet", which defaults to
TRUE
. Set this option to FALSE
to see more info about gargle's
activities, which can be helpful for troubleshooting.
