Hi All,

Does anyone have a need to resolve regular expressions in the dbpr command?

I often issue a dbgrep immediately followed by a dbpr and thought it would be useful if I could do both together.  Example:

sioc-sys0-ml00>dbgrep("SIOC:SYS0:ML00:FWF0*")
SIOC:SYS0:ML00:FWF01
SIOC:SYS0:ML00:FWF02
sioc-sys0-ml00>dbpr("SIOC:SYS0:ML00:FWF01")
ASG:                BUSY: 0             DESC: spare         DISA: 0             
DISP: 0             DISV: 1             NAME: SIOC:SYS0:ML00:FWF01              
NORD: 1             SEVR: NO_ALARM      STAT: NO_ALARM      TPRO: 0             
VAL: (nil) 
sioc-sys0-ml00>dbpr("SIOC:SYS0:ML00:FWF02",)
ASG:                BUSY: 0             DESC: spare         DISA: 0             
DISP: 0             DISV: 1             NAME: SIOC:SYS0:ML00:FWF02              
NORD: 1             SEVR: NO_ALARM      STAT: NO_ALARM      TPRO: 0             
VAL: (nil) 

...could be replaced with:

sioc-sys0-ml00>dbpr("SIOC:SYS0:ML00:FWF0*")
SIOC:SYS0:ML00:FWF01
ASG:                BUSY: 0             DESC: spare         DISA: 0             
DISP: 0             DISV: 1             NAME: SIOC:SYS0:ML00:FWF01              
NORD: 1             SEVR: NO_ALARM      STAT: NO_ALARM      TPRO: 0             
VAL: (nil) 
SIOC:SYS0:ML00:FWF02
ASG:                BUSY: 0             DESC: spare         DISA: 0             
DISP: 0             DISV: 1             NAME: SIOC:SYS0:ML00:FWF02              
NORD: 1             SEVR: NO_ALARM      STAT: NO_ALARM      TPRO: 0             
VAL: (nil) 

In addition to the interest level argument, I'd like to add an option to display them in one column.  Example:

sioc-sys0-ml00>dbpr("SIOC:SYS0:ML00:FWF0*",0,1)
SIOC:SYS0:ML00:FWF01
    ASG:                
    BUSY: 0             
    DESC: spare         
    DISA: 0             
    DISP: 0             
    DISV: 1             
    NAME: SIOC:SYS0:ML00:FWF01              
    NORD: 1             
    SEVR: NO_ALARM      
    STAT: NO_ALARM      
    TPRO: 0             
    VAL: (nil) 
SIOC:SYS0:ML00:FWF02
    ASG:                
    BUSY: 0             
    DESC: spare           
    DISA: 0             
    DISP: 0            
    DISV: 1             
    NAME: SIOC:SYS0:ML00:FWF02              
    NORD: 1             
    SEVR: NO_ALARM      
    STAT: NO_ALARM      
    TPRO: 0             
    VAL: (nil) 

Motivation: Currently the SLAC electron beam line controls group uses an IRMIS crawler to get PV information into the RDB by crawling every IOCs st.cmd.  Our engineers add new, but valid, syntax that results in us having to massage that crawler quite a bit.  I would like to add a command to all of our IOC startup scripts that generates a list of PVs and fields that can easily crawled and inserted into the IRMIS RDB.  Example:

iocshCmd("dbpr(*,5,1) >/data/iocInfo/IOC.pvEveryField")

Opinions?

Could this be a code-a-thon topic?
