HI. . . I had a lot of JUL logp code to convert to SLF4J so I tweaked the migrator in a few ways: * Added MultiLineConversionRule to accommodate cases such as: log.logp(Level.FINEST, MyClass.class.getName(), "myMethod", "Log entry"); * Passed Reader into LineConverter in order to more easily control reading in of additional lines * Changed ConversionRule.replace() to append the match.group(1) text to the replacement line if group(1) exists * Added additional SingleConversionRules to accommodate additional logp scenarios I converted quite a bit of code with minimal cleanup. Where that was necessary was pretty unavoidable: * Code using Level, handlers, custom configuration, etc * Log entries with commas get a bit mungled, e.g.: log.logp(Level.FINEST, MyClass.class.getName(), "myMethod", "This, e.g., would get mungled"); I did not do any regression testing but it worked in my case. Attaching the patch file in case I'm not the only slf4j fan converting logps!
