A jira issue sounds good. Given that the RollingFileAppender already inherits from FileAppender and is getting pretty complicated to maintain, I would prefer a new class, e.g. ExtFileAppender. At the same time, since the idea of a resolver also makes sense in RollingFileAppender, FileAppender might still be the right place. It's a case of definitely, maybe. Ralph Goers wrote:
I would suggest you create a Jira issue for this. I would suggest the ability to add a custom pattern resolver to the appender might be what you want. Before Logback I had written my own logging framework that supported this. I had considered making this request myself but so far I am not sure that we actually need it yet. It could look something like:
<appender name="file" class="ch.qos.logback.core.FileAppender"> <File resolver="com.mycorp.logback.MyPatternResolver">myjob.%{host}.%{datetime}.log</File> <Append>false</Append> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%msg%n</Pattern> </layout> </appender>
The Resolver interface would have a single method that looks like String resolve(String pattern)

Thanks for the answer, Hannes.
However a time-based rollover is not what I am looking for. My program executes one job at a time. There are several jobs whose duration varies from a couple of seconds to several hours. I simply want to log the results of a job in a single file, and have the filename contain a timestamp.
I will have to do this programmatically obviously, but I'm having trouble setting up the file appender programmatically.
