log_set_defaults {DIZtools}

Set default options for all log-functions

Description

This function sets the default log options. Parameters not supplied to this function will be set with the default value. If you want to reset all parameters to the default ones, run log_set_defaults(reset = TRUE). This can also be combined with a new custom default value: log_set_defaults(reset = TRUE, prefix = "Prefix") which will reset all parameters to default and afterwards assign "Prefix" as new global prefix.

Usage

log_set_defaults(
  print_this = NULL,
  type = NULL,
  ui = NULL,
  console = NULL,
  logfile = NULL,
  logjs = NULL,
  prefix = NULL,
  suffix = NULL,
  findme = NULL,
  logfile_dir = NULL,
  headless = NULL,
  reset = FALSE
)

Arguments

print_this

(Optional, String, default: "")

type

(Optional, String, default: "Info") E.g. "Warning", "Error". Default: "Info"

ui

(Optional, Boolean/String, default: FALSE) If true, the message will also be printed to the user in form of a modal. Can also be a string.

console

(Optional, Boolean/String, default: TRUE) If true, the message will also be printed to the console as is. Can also be a string.

logfile

(Optional, Boolean, default: TRUE) If true (default) the print_this string will also be printed to the console.

logjs

(Optional, Boolean, default: FALSE) If true (default: false) the print_this string will also be printed to the javascript-console. This only makes sense, if the gui is active.

prefix

Prefix (Optional, String, default: "") This is useful if print_this is an array/list. Each entry will then be new row with this prefix.

suffix

Suffix (Optional, String, default: "") Same like prefix but at the end of each line.

findme

(Optional, String, default: "") Recommended with length 10. String to find the message in the code. E.g. 10-digit random hex from https://onlinetools.com/random/generate-random-hexadecimal-numbers

logfile_dir

(Optional, String, default: "tempdir()") The absolute path to folder where the logfile will be stored.

headless

(Optional, Boolean, default: TRUE) Indicating, if the function is run only in the console (headless = TRUE) or on a GUI frontend (headless = FALSE).

reset

(boolean, default = FALSE) Should all parameters be reset to their default values?

Value

No return value, called for side effects (see description).
