\title{Transforms all passed R objects into a JSON list}
\usage{
formatter_json(
...,
.logcall = sys.call(),
.topcall = sys.call(-1),
.topenv = parent.frame()
)
}
\arguments{
\item{...}{passed to \code{toJSON} wrapped into a \code{list}}
\item{.logcall}{the logging call being evaluated (useful in
formatters and layouts when you want to have access to the raw,
unevaluated R expression)}
\item{.topcall}{R expression from which the logging function was
called (useful in formatters and layouts to extract the calling
function's name or arguments)}
\item{.topenv}{original frame of the \code{.topcall} calling function
where the formatter function will be evaluated and that is used
to look up the \code{namespace} as well via \code{logger:::top_env_name}}
}
\value{
character vector
}
\description{
Transforms all passed R objects into a JSON list
}
\note{
This functionality depends on the \pkg{jsonlite} package.

\examples{
\dontshow{old <- logger:::namespaces_set()}
log_formatter(formatter_json)
log_layout(layout_json_parser())
log_info(everything = 42)
log_info(mtcars = mtcars, species = iris$Species)
