Jakub created LOG4J2-2339:
-----------------------------

             Summary: format multiple conversion characters with one conversion specifier
                 Key: LOG4J2-2339
                 URL: https://issues.apache.org/jira/browse/LOG4J2-2339
             Project: Log4j 2
          Issue Type: New Feature
          Components: Core, Pattern Converters
    Affects Versions: 2.8.2
            Reporter: Jakub


I am writing on suggestion from [~remkop@yahoo.com] in [https://stackoverflow.com/questions/50311762/log4j-set-class-and-method-summary-length-in-pattern] 

 

I would like to format multiple conversion characters with one conversion specifier.

As Remko explained, it is currently not possible

_No, each modifier applies to one conversion. But Log4j could add a new converter that means what you want. You can propose such a new converter on the mailing list or issue tracker_

Would it be a useful feature to add to log4j2 ? Would it be hard to implement ?

 

EG

I would like to set summary length of class.method.line with

%-60.60CML

It's not possible now. Below what doc states

[https://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html]
{quote}Each conversion specifier starts with a percent sign (%) and is followed by optional format modifiers and a conversion charact*er*. The conversion charact*er* specifies the type of data

The pattern parser knows when it has reached the end of a conversion specifier when it reads a conversion charact*er*.
{quote}
It writes only about single conversion character, I would like to modify multiple conversion characters with one conversion specifier.
