--------------------------------------

Hi Tomasz,

Thank you for yet another cool contribution to the project. Contrary to folder customizations in IDEA, in the case of logback removed stack trace lines cannot be "unremoved" whereas in IDEA they can be unfolded. There must a way to signal to the user which sort (which package) of lines were removed. Thus, it seems to me that Przemysław's remark about border lines becomes particularly relevant in our context.

As for Nick's remark about cluttering the pattern, we could use properties and re-use the masked packages. For example, we could write

<property name="mask" 
                value="java.lang.reflect.Method,
                           org.apache.catalina,
                           org.springframework.aop,
                           org.springframework.security,
                           org.springframework.transaction,
                           org.springframework.web,
                           sun.reflect,
                           net.sf.cglib"/>
 
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">    
  <encoder>   
    <pattern>%d %level %thread %logger{1} | %m%n%rEx{full, ${mask}}</pattern>
  </encoder>
  ....
</appender>
     
Note that the mask property could be defined in a file as well.

> Many frameworks and libraries like Spring or EJB are introducing hundreds of synthetic method invocations (AOP, dynamic proxies, CGLIB-generated classes, etc.) They are irrelevant for most of the time and only cluttering the stack traces printed by Logback.
> It would be nice to have possibility to filter (possibly by providing a set of patterns in logback.xml) each stack trace line and skip selected ones. Similar feature is implemented in some IDEs, see: http://blogs.jetbrains.com/idea/2010/07/console-folding-customization.
