Is there a way to contribute non-standard submodes

[stasvlasov]

I spend some time configuring additional submode for viewing CUPS (printing system) 'error_log' file with is usually located at /var/log/cups/error_log

The problem was that THREAD field that was optional and I had to use regex in format.

I ended up with following and it works for me. I was wondering how I should to contribute this little bit as this could be too specific for adding to logview-std-submodes.

(setq logview-additional-submodes
        '(("CUPS(error_log)"
           (format . "LEVEL [TIMESTAMP]<<RX:THREAD:\\(?:[ \t]+\\[[^]\n]+\\][ \t]+\\|[ \t]+\\)>>MESSAGE")
           (levels . "CUPS(error_log)")
           (timestamp . ("CUPS(error_log)")))))
  (setq logview-additional-level-mappings 
        '(("CUPS(error_log)"
           (error "E")
           (warning "W")
           (information "I")
           (debug "D")
           (trace))))
  (setq logview-additional-timestamp-formats
        '(("CUPS(error_log)"
           (java-pattern . "dd/MMM/yyyy:HH:mm:ss Z"))))

Probably should be fine. How does Logview handle optional threads, I have never tried myself? I guess regexp above means the brackets are included in thread name?
