==== Filtering logs ====

A quick tip for finding errors in the log files created by the logger is to search the log file using a regular expression.\\

The expression we use is ''.(?<!- 0 - )$''. It searches for the lines not ending in -0- which is the normal end of line in the log if no errors have occurred.\\

In Notepad++ this would look like:\\
{{:code:open-source:hse-logger:howto:pasted:20220706-152542.png}} \\

Furthermore, if using it in earnest, this can be mapped to a macro with a shortcut.
