Module BatLog.Easy

module Easy: sig .. end
A simple-to-use logger with verbosity levels that outputs by default to stderr (changeable at runtime) with the date and time at the beginning of each log message.
Since 2.0

val level : BatLog.easy_lev Pervasives.ref
Set this ref to the lowest level of log you want logged. For example, Easy.level := `always disables all logging except that at the `always level. Setting Easy.level := `info will enable logging for `info, `warn, `error, `fatal and `always levels.

Set this ref to the output you want logging messages to go to. Defaults to stderr.

val output : unit BatIO.output Pervasives.ref
val log : ?fp:string -> BatLog.easy_lev -> string -> unit
log lev msg logs the message msg if the current logging level is lev or lower.
val logf : ?fp:string ->
BatLog.easy_lev -> ('a, unit BatIO.output, unit) Pervasives.format -> 'a
As log, but instead of a string message, a printf format is allowed with whatever arguments are appropriate.
