Options consulted by gargleSource:
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
options( gargle_oauth_email = "firstname.lastname@example.org", gargle_oauth_cache = "/path/to/folder/that/does/not/sync/to/cloud" )
gargle_oauth_email() gargle_oob_default() gargle_oauth_cache() gargle_oauth_client_type() gargle_verbosity() local_gargle_verbosity(level, env = parent.frame()) with_gargle_verbosity(level, code)
Verbosity level: "debug" > "info" > "silent"
The environment to use for scoping
Code to execute with specified verbosity level
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:
A glob pattern that indicates your preferred Google domain. Example:
TRUEto allow email and OAuth token auto-discovery, if exactly one suitable token is found in the cache.
NAto force the OAuth dance in the browser.
TRUE unconditionally on RStudio Server,
Posit Workbench, Posit Cloud, or Google Colaboratory, since it is not
possible to launch a local web server in these contexts. In this case, for
the final step of the OAuth dance, the user is redirected to a specific URL
where they must copy a code and paste it back into the R session.
In all other contexts,
gargle_oob_default() consults the option named
"gargle_oob_default", then the option named
eventually defaults to
"oob" stands for out-of-band. Read more about out-of-band authentication in
gargle_oauth_cache() returns the option named "gargle_oauth_cache",
NA. If defined, the option must be set to a logical value or
TRUE means to cache using the default user-level cache file,
FALSE means don't cache, and
NA means to
guess using some sensible heuristics.
gargle_oauth_client_type() returns the option named
"gargle_oauth_client_type", if defined. If defined, the option must be either
"installed" or "web". If the option is not defined, the function returns:
"web" on RStudio Server, Posit Workbench, Posit Cloud, or Google Colaboratory
Primarily intended to help infer the most suitable OAuth client type when a user is relying on a built-in client, such as the tidyverse client used by packages like bigrquery, googledrive, and googlesheets4.
gargle_verbosity() returns the option named "gargle_verbosity", which
determines gargle's verbosity. There are three possible values, inspired by
the logging levels of log4j:
"debug": Fine-grained information helpful when debugging, e.g. figuring out how
token_fetch()is working through the registry of credential functions. Previously, this was activated by setting an option named "gargle_quiet" to
"info" (default): High-level information that a typical user needs to see. Since typical gargle usage is always indirect, i.e. gargle is called by another package, gargle itself is very quiet. There are very few messages emitted when
gargle_verbosity = "info".
"silent": No messages at all. However, warnings or errors are still thrown normally.
