LayoutGlue {lgr} | R Documentation |
Format Log Events as Text via glue
Description
Format a LogEvent as human readable text using glue::glue. The function is evaluated in an environment in which it has access to all elements of the LogEvent (see examples). This is more flexible than LayoutFormat, but also more complex and slightly less performant.
