Fernando Díaz commented on LOG4J2-1013:


Using that branch, if I run 
{{org.apache.logging.log4j.core.lookup.MainInputArgumentsLookupTest}} with the 
command line {{--file foo.txt}} and the following pattern layout:

%d [%t] [${main:1}][${main:-1}][${main:--file}][${main:bad:-${main:--file}}] 
%-5level: %msg%n%throwable

The output is:

2018-03-13 02:23:40,824 [main] [foo.txt][1][foo.txt][foo.txt] ERROR: this is an 
error message

Taking a look at other tests, in particular in {{StrSubstitutorTest}}, I think 
the output {{[1]}} is correct because {{main}} is the key in that particular 

I've included some unit tests. All test pass.

> Accessing Main Arguments by using index based look up works : $\{main:0}
> Accessing Main Arguments by using name based look up doesn't work : 
> $\{main:--file}
> When trying to access by name it doesn't retrieve the argument but retrieves 
> "-file".
