lgr (version 0.4.2)

LoggerGlue: LoggerGlue

Description

LoggerGlue uses glue::glue() instead of base::sprintf() to construct log messages. glue is a very well designed package for string interpolation. It makes composing log messages more flexible and comfortable at the price of an additional dependency and slightly less performance than sprintf().

Details

glue() lets you define temporary named variables inside the call. As with the normal Logger, these named arguments get turned into custom fields; however, you can suppress this behaviour by making named argument start with a ".". Please refer to vignette("lgr", package = "lgr") for examples.
