View or comment on issue using this link https://jira.qos.ch/browse/SLF4J-371 ============================== 1 comment ------------------------------ Eric Kolotyluk on 24/Dec/21 10:08 PM Please support log4j2 style lambda expressions... While playing with fluent in 2.0.0-alpha5 {code:java} Callable task = () -> {System.out.println("task evaluated"); return "called";}; logger.atDebug().log("Lazy logging {}", task.call()); {code} At log level "debug" it prints {code:java} task evaluated 15:39:38.061 [main] DEBUG net.kolotyluk.net.LagTests - Lazy logging called {code} but at log level "info" it still prints {code:java} task evaluated {code} Also, IMHO, fluent log statements are ugly. Using lambdas, {code:java} logger.debug(() -> { ... }){code} would give me 90% of what I want, whereas {code:java} logger.debug("format {} ... {}", () -> {...}, () -> {...}) {code} is just gravy. ============================== This message was sent by Atlassian Jira (v8.8.0#808000-sha1:e2c7e59)
