Logger.Format (gb.logging)
Property Format As String
Sets or returns the format for log messages produced by the
Logger object.
The default format is [$(now)] [$(levelname)] [$(callLocation)] $(message).
The format string contains tokens that define which information will be included in the log message.
The token literals and their meanings are as follows:
-
$(message) : Includes the provided message text.
-
$(now) : Includes the current system date and time.
-
$(callLocation) : Equivalent to $(callFile).$(callFunction)$(callLine).
-
$(callFile) : Includes the name of the source code file for the method that invoked the log message construction.
-
$(callLine) : Includes the source code line in the Gambas program method that invoked the log message construction.
-
$(callFunction) : Includes the name of the function that invoked the log message construction.
-
$(date) : Includes the current system date
-
$(time) : Includes the current system time
-
$(ptimer) : Includes the process timer value expressed in seconds and subseconds.
-
$(ptimerint) : includes the process timer value expressed in seconds.
-
$(levelno) : Includes the message level as an integer.
-
$(levelname) : Includes the string representation of the message level.
-
$(version) : Includes the application version.
-
$(gbversion) : Includes the Gambas runtime version.
-
$(host) : Includes the system hostname (of the system where the Gambas program is running).
-
$(pid) : Includes the process id of the task that invoked the log message call.
The tokens are case sensitive. Ensure you used the exact case above.
Examples
Dim hLog as new Logger
hLog.Format="[$(now)] [$(levelname)] [$(callLocation)] $(message)"
would subsequently produce log file message lines similar to the following
