logger (version 0.4.0)

log_separator: Logs a long line to stand out from the console

Description

Logs a long line to stand out from the console

Usage

log_separator(
  level = INFO,
  namespace = NA_character_,
  separator = "=",
  width = 80,
  .logcall = sys.call(),
  .topcall = sys.call(-1),
  .topenv = parent.frame()
)

Arguments

level

log level, see log_levels() for more details

namespace

string referring to the logger environment / config to be used to override the target of the message record to be used instead of the default namespace, which is defined by the R package name from which the logger was called, and falls back to a common, global namespace.

separator

character to be used as a separator

width

max width of message -- longer text will be wrapped into multiple lines

.logcall

the logging call being evaluated (useful in formatters and layouts when you want to have access to the raw, unevaluated R expression)

.topcall

R expression from which the logging function was called (useful in formatters and layouts to extract the calling function's name or arguments)

.topenv

original frame of the .topcall calling function where the formatter function will be evaluated and that is used to look up the namespace as well via logger:::top_env_name
