Transforms all passed R objects into a JSON list

formatter_json(
...,
.logcall = sys.call(),
.topcall = sys.call(-1),
.topenv = parent.frame()
)

## Arguments

...

passed to toJSON wrapped into a list

.logcall

the logging call being evaluated (useful in formatters and layouts when you want to have access to the raw, unevaluated R expression)

.topcall

R expression from which the logging function was called (useful in formatters and layouts to extract the calling function's name or arguments)

.topenv

original frame of the .topcall calling function where the formatter function will be evaluated and that is used to look up the namespace as well via logger:::top_env_name

character vector

## Note

This functionality depends on the jsonlite package.

This is a log_formatter potentially to be used with layout_json_parser, for alternatives, see formatter_paste, formatter_sprintf, formatter_glue, formatter_glue_or_sprintf, formatter_logging, formatter_pander and skip_formatter for marking a string not to apply the formatter on it.
