Set pipeflow log layout

This function provides an easy way to set the basic log layout of the pipeline logging. For a fine-grained control of the logger, which you can retrieve via lgr::get_logger("pipeflow"), see e.g. the logger_config function from the lgr package.

Usage

set_log_layout(layout = c("text", "json"))

Arguments

layout

Layout name, which at this point can be either 'text' or 'json'.

Value

invisibly returns a Logger object

Examples

p <- Pipeline$new("pipe", data = 1:2)
p$add("add1", \(data = ~data, x = 1) x + data)
p$run()
