Show HN: Decorate Java stack traces with source code snippets

One big "off-label" use of stack traces for me is to determine the caller method of the current method. I use it in a lightly customised lig function to also log the name of the method thst has emitted a log string.

If I understand your use case, most loggers (like Logback) have the possiblity to automatically include the name of the method that called the log-statement.

Logback even supports including the call chain in the output, so you could include the parent method, grand parent method etc. This probably uses reflection, so it could have a negative impact for applications that need a high performance.

Thanks. Will take a look. I don't use logging frameworks in smaller projects.

If you're using Java 9+ there is an official API to do that. It's the StackWaker class.
