Raman Gupta commented on LOG4J2-1685:
-------------------------------------
Looking at the existing code, I see an option noConsoleNoAnsi, however this
option only takes effect if System.console() == null. This is not always true
-- for example, an app logging to standard output inside a docker container
will have System.console() != null, however in this environment it may still be
useful to disable ansi.
I have therefore added a parallel option `disableAnsi` in the attached patch,
which disables ansi unconditionally.

Thanks!
> Single property to disable all color output
> -------------------------------------------
>
> Key: LOG4J2-1685
> URL: https://issues.apache.org/jira/browse/LOG4J2-1685
> Project: Log4j 2
> Issue Type: Improvement
> Components: Appenders
> Affects Versions: 2.7
> Reporter: Raman Gupta
> Priority: Minor
>
> 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.
