How to know if sym file for new update after .Q.en

[pmallon]

Hi,

You should be able to check by the timestamp on the sym file:

 

q).z.p 2022.03.24D13:36:35.138809000 
q)t:([]s:`a`b`c) 
q).Q.en[`:.]t s - a b c 
q)ls -lrt sym "-rw-r--r-- 1 pat pat 14 Mar 24 13:36 sym" 
q)/ add a sym to t 
q)t:([]s:`a`b`c`d) 
q).z.p 2022.03.24D13:37:20.140371000 
q).Q.en[`:.]t s - a b c d 
q)ls -lrt sym "-rw-r--r-- 1 pat pat 16 Mar 24 13:37 sym"

 

If that doesn’t work for you, maybe a simply modified version like:

 

q)modQen:{s:sym;.Q.en[x]y;sym except s} 
q)t:([]s:`a`b`c`d`e) / add e to t 
q)modQen[`:.;t] ,`e 
q)/ run again to show no update to sym, .i.e empty list returned 
q)modQen[`:.;t] `symbol$()

 

 

 

Thanks,
