Format Log Events as Text via glue
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.
lgr::Layout -> LayoutGlue
fmtA string that will be interpreted by glue::glue()
new()
LayoutGlue$new(
fmt = "{pad_right(colorize_levels(toupper(level_name)), 5)} [{timestamp}] msg"
)format_event()
LayoutGlue$format_event(event)
set_fmt()
LayoutGlue$set_fmt(x)
set_colors()
LayoutGlue$set_colors(x)
toString()
LayoutGlue$toString()
clone()
The objects of this class are cloneable with this method.
LayoutGlue$clone(deep = FALSE)
deepWhether to make a deep clone.
lgr exports a number of formatting utility functions that are
useful for layout glue: colorize_levels(), pad_left(), pad_right().
