SLF4J / SLF4J-371 [Resolved] Support the lambda expression in the Logger ============================== Here's what changed in this issue in the last few minutes. There is 1 comment. 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)

[JIRA] Updates for SLF4J-528: Add a LoggerFactory method that infers caller class
by QOS.CH (JIRA) 22 Dec '21

SLF4J / SLF4J-528 [Open] Add a LoggerFactory method that infers caller class ============================== Here's what changed in this issue in the last few minutes. There is 1 comment. View or comment on issue using this link https://jira.qos.ch/browse/SLF4J-528 ============================== 1 comment ------------------------------ Ceki Gülcü on 22/Dec/21 2:23 PM [~suchintan] Anyone can add a new {{getLogger()}} method to {{LoggerFactory}}, as mentioned above the task is non trivial. This issue needs to be explored in a systematic way before being integrated into SLF4J. By systematic, I mean that alternative implementations need to be studied carefully and benchmarked. ============================== This message was sent by Atlassian Jira (v8.8.0#808000-sha1:e2c7e59)

[JIRA] Updates for SLF4J-529: Platform Logging bridge should use MessageFormat but it's using String.format

SLF4J / SLF4J-529 [Open] Platform Logging bridge should use MessageFormat but it's using String.format ============================== Here's what changed in this issue in the last few minutes. This issue has been created This issue is now assigned to you. View or comment on issue using this link https://jira.qos.ch/browse/SLF4J-529 ============================== Issue created ------------------------------ Taku Miyakawa created this issue on 22/Dec/21 2:11 PM Summary: Platform Logging bridge should use MessageFormat but it's using String.format Issue Type: Bug Affects Versions: 2.0.0-alpha5 Assignee: SLF4J developers list Components: Unspecified Created: 22/Dec/21 2:11 PM Environment: Priority: Major Reporter: Taku Miyakawa External issue URL: https://github.com/qos-ch/slf4j/pull/273 Description: [java.lang.System.Logger.log|https://docs.oracle.com/en/java/javase/17/docs/…] is specified to accept the message format of MessageFormat. However, the current SLF4JPlatformLogger implementation uses String.format instead of MessageFormat. As a result, the current implementation cannot format the message correctly. h1. Expected and actual behavior {code:java} LoggerFinder finder = System.LoggerFinder.getLoggerFinder(); Logger systemLogger = finder.getLogger("smoke", null); systemLogger.log(Level.INFO, "hello {0}", "world"); {code} Expected output: {code} INFO smoke - hello world {code} Actual output: {code} INFO smoke - hello {0} {code} ============================== This message was sent by Atlassian Jira (v8.8.0#808000-sha1:e2c7e59)
