Logging scope-specific parameters of events

With log_params you can define a set of named parameters, which are common for events from the same scope (for example inside an observer). These parameters will be added to event-specific parameters and logged within the same log entry.

log_params(...)

Arguments

...	a set of named objects (usually of type character, numeric, or date) to be logged as event parameters.

Details

The function takes all objects passed inside ... argument, evaluates them, and stores them in a new environment called log_setting which is assigned to the parent environment from which the log_params function was called.

Examples

if (interactive()) {
  set_logging()
  shiny::shinyApp(
    ui = shiny::fluidPage(log_init()),
    server = function(input, output) {
      set_logging_session()
      observe({
        log_params("observer" = "A")
        log_event("Event A.1")
        log_event("Event A.2")
      })
      observe({
        log_params("observer" = "B")
        log_event("Event B.1")
        log_event("Event B.2")
      })
    }
  )
