\section{Configurable settings}{

\subsection{vcr options}{
\subsection{File locations}{
\itemize{
\item \code{dir} Cassette directory
\item \code{write_disk_path} (character) path to write files to
for any requests that write responses to disk. by default this parameter
is \code{NULL}. For testing a package, you'll probably want this path to
be in your \verb{tests/} directory, perhaps next to your cassettes
directory, e.g., where your cassettes are in \code{tests/fixtures}, your
files from requests that write to disk are in \code{tests/files}.
If you want to ignore these files in your installed package,
add them to \code{.Rinstignore}. If you want these files ignored on build
then add them to \code{.Rbuildignore} (though if you do, tests that depend
on these files probably will not work because they won't be found; so
you'll likely have to skip the associated tests as well).
}
}

\subsection{Contexts}{
\itemize{
\item \code{turned_off} (logical) VCR is turned on by default. Default:
\code{FALSE}
\item \code{allow_unused_http_interactions} (logical) Default: \code{TRUE}
\item \code{allow_http_connections_when_no_cassette} (logical) Determines how vcr
treats HTTP requests that are made when no vcr cassette is in use. When
\code{TRUE}, requests made when there is no vcr cassette in use will be allowed.
When \code{FALSE} (default), an \link{UnhandledHTTPRequestError} error will be raised
for any HTTP request made when there is no cassette in use
}
}

\subsection{Filtering}{
\itemize{
\item \code{ignore_hosts} (character) Vector of hosts to ignore. e.g., localhost, or
google.com. These hosts are ignored and real HTTP requests allowed to go
through
\item \code{ignore_localhost} (logical) Default: \code{FALSE}
\item \code{ignore_request} List of requests to ignore. NOT USED RIGHT NOW, sorry
\item \code{filter_sensitive_data} named list of values to replace. Format is:\preformatted{list(thing_to_replace_it_with = thing_to_replace)
}

We replace all instances of \code{thing_to_replace} with
\code{thing_to_replace_it_with}. Before recording (writing to a cassette) we do
the replacement and then when reading from the cassette we do the reverse
replacement to get back to the real data. Before record replacement happens
in internal function \code{write_interactions()}, while before playback
replacement happens in internal function \code{YAML$deserialize()}
\item \code{filter_request_headers} (character/list) \strong{request} headers to filter.
A character vector of request headers to remove - the headers will not be
recorded to disk. Alternatively, a named list similar to
\code{filter_sensitive_data} instructing vcr with what value to replace the
real value of the request header.
\item \code{filter_response_headers} (named list) \strong{response} headers to filter.
A character vector of response headers to remove - the headers will not be
recorded to disk. Alternatively, a named list similar to
\code{filter_sensitive_data} instructing vcr with what value to replace the
real value of the response header.
}
}

}

\subsection{Errors}{
\itemize{
\item \code{verbose_errors} Do you want more verbose errors or less verbose
errors when cassette recording/usage fails? Default is \code{FALSE}, that is,
less verbose errors. If \code{TRUE}, error messages will include more details
about what went wrong and suggest possible solutions. For testing
in an interactive R session, if \code{verbose_errors=FALSE}, you can run
\code{vcr_last_error()} to get the full error. If in non-interactive mode,
which most users will be in when running the entire test suite for a
package, you can set an environment variable (\code{VCR_VERBOSE_ERRORS})
to toggle this setting (e.g.,
\verb{Sys.setenv(VCR_VERBOSE_ERRORS=TRUE); devtools::test()})
}
\subsection{Internals}{
\itemize{
\item \code{cassettes} (list) don't use
\item \code{linked_context} (logical) linked context
\item \code{uri_parser} the uri parser, default: \code{crul::url_parse()}
}
}

\subsection{Logging}{
\itemize{
\item \code{log} (logical) should we log important vcr things? Default: \code{FALSE}
\item \code{log_opts} (list) Additional logging options:
\itemize{
\item 'file' either \code{"console"} or a file path to log to
\item 'log_prefix' default: "Cassette". We insert the cassette name after
that prefix, then the rest of the message.
\item More to come...
}
}
}

}

\subsection{Cassette Options}{

These settings can be configured globally, using \code{vcr_configure()}, or
locally, using either \code{use_cassette()} or \code{insert_cassette()}. Global
settings are applied to \emph{all} cassettes but are overridden by settings
defined locally for individual cassettes.
\itemize{
\item \code{record} (character) One of 'all', 'none', 'new_episodes', or 'once'.
See \link{recording}
\item \code{match_requests_on} vector of matchers. Default: (\code{method}, \code{uri})
See \link{request-matching} for details.
\item \code{serialize_with}: (character) "yaml" or "json". Note that you can have
multiple cassettes with the same name as long as they use different
serializers; so if you only want one cassette for a given cassette name,
make sure to not switch serializers, or clean up files you no longer need.
\item \code{json_pretty}: (logical) want JSON to be newline separated to be easier
to read? Or remove newlines to save disk space? default: FALSE
\item \code{persist_with} (character) only option is "FileSystem"
\item \code{preserve_exact_body_bytes} (logical) preserve exact body bytes for
\item \code{re_record_interval} (numeric) When given, the cassette will be
re-recorded at the given interval, in seconds.
\item \code{clean_outdated_http_interactions} (logical) Should outdated interactions
be recorded back to file. Default: \code{FALSE}
}
}
