Accessing logs from the bottom of the rotating logger about cleanroomlogger HOT 1 CLOSED

Hello,

Glad to hear you're finding CleanroomLogger useful!

I wouldn't recommend trying to read and parse the logs to extract the last X entries. For one, the boundaries between log messages may not be clear depending on how your formatters are configured and whether your log messages themselves might include such characters as newlines ("\n"). It also means if you decide to change your format, you'll probably need to rework your parsing code too. Such a solution is likely to be brittle in the long-run.

Instead, you might want to look into the BufferedLogRecorder generic class, which allows you to store an arbitrary number of the most recent items in memory, for later retrieval through the buffer property.

There are three built-in subclasses that each provide slightly different functionality depending on your needs:

• BufferedMessageRecorder stores Strings containing the formatted log message.
• BufferedLogEntryRecorder stores LogEntry values, the structs that CleanroomLogger uses to represent individual log messages.
• BufferedLogEntryMessageRecorder stores a (LogEntry, String) tuple containing the LogEntry and the formatted log message.

Hope you can find the solution you're looking for among these options.

E.
