FileLogger

FileLogger appends Str log entries to a file. You can add a FileLogger as a Log handler:

sysLogger := FileLogger
{
  dir = scriptDir
  filename = "sys-{YYMM}.log"
}
Log.addHandler |rec| { sysLogger.writeLogRec(rec) }

See filename for specifying a datetime pattern for your log files.

Directory used to store log file(s).

Log filename pattern. The name may contain a pattern between {} using the pattern format of DateTime.toLocale. For example to maintain a log file per month, use a filename such as "mylog-{YYYY-MM}.log".

Constructor must set dir and filename

Callback called each time the file logger opens an existing or new log file. Callback should write any header information to the given output stream. The callback will occur on the logger's actor, so take care not incur additional actor messaging.
