Subject [jira] [Commented] (LOG4J2-1685) Single property to disable all color output
Date Sat, 12 Nov 2016 17:48:58 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-1685?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15659998#comment-15659998

Gary Gregory commented on LOG4J2-1685:
--------------------------------------

I applied the patch to Git master with {{git apply FILENAME}}. 

I get a compile error in {{PatternSelectorTest}}. 

To fix that I changed the code to use the {{Builder}} but then I got a bunch of errors running
the build with {{mvn clean test}}. I usually skip the OSGi test which give me errors locally
(but Jenkins is OK) by using {{mvn clean test -pl !log4j-osgi}}

What happens when you run {{mvn clean test}}?

> I am deploying an app to a Windows server. The app will write logs to standard output
which will then be captured by some wrapper process.
> My default configuration contains ansi escapes for color, because they are nice for every
situation except this one.
> It would be nice if there was a simple way to disable all ansi output via a system property
and/or environment variable e.g.
> `-Dlog4j.ansi.enabled=false`
> This would operate similarly to the Spring Boot `spring.output.ansi.enabled` property
(http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-logging.html).
> In Spring Boot I believe this is handled by using conditionals in their logback configuration
(which would be super-nice in log4j also). With conditional layout I could very easily do
this myself by specifying two different Pattern layouts in my config file, one with color
and one without, conditional on some system property or env var I define.
