Eugene Petrenko created LOGBACK-1248: ---------------------------------------- Summary: Allow leading zeros in %i pattern Key: LOGBACK-1248 URL: https://jira.qos.ch/browse/LOGBACK-1248 Project: logback Issue Type: Bug Components: logback-core Affects Versions: 1.1.7 Reporter: Eugene Petrenko Assignee: Logback dev list I use the appender like {code} <appender name="ROLL-INFO" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"> <fileNamePattern>${IR}/vcs-info-%d{yyyy-MM-dd}.%i.log</fileNamePattern> <maxFileSize>15MB</maxFileSize> <maxHistory>100</maxHistory> </rollingPolicy> <encoder> <pattern>${log-format}</pattern> </encoder> </appender> {code} the pattern I specify includes file counter in each day. In may case it may easily turn out I have hundreds of files per day. The problem is that {{%i}} syntax does not allow me to have leading zeroes in the names I generates. This ends up it's a but tricky to look through files list I have on my disk, which are sorted in sexicographical order. Having an ability to force adding leading zeroes to the pattern will solve the issue. -- This message was sent by Atlassian JIRA (v6.4.12#64027)
