Bug #11545
Want configurable output field separator for libofmt
100%
Description
As part of adding the connstat(1M) tool (see delphix/delphix-os@374241a), Delphix made some changes to the ofmt_* functions in libinetutil. Those have since been moved into their own libofmt library, so as part of the porting connstat, we'll want to pull in those changes and also document them in the manual page.
The changes to ofmt were originally done by Sebastien Roy at Delphix, and the manual page was written by Cody Mello at Joyent, while porting it as part of OS-7325.

Updated by Since these changes are used by connstat(1M), I ran the tool to verify that they work.
For example, it calls ofmt_print for every TCP connection. When there are multiple connections, the header is only printed once since it's using both OFMT_NOHEADER and ofmt_print_header:
cpm@utu ~ % connstat -F laddr=0.0.0.0 LADDR LPORT RADDR RPORT STATE 0.0.0.0 22 0.0.0.0 0 LISTEN 0.0.0.0 111 0.0.0.0 0 LISTEN 0.0.0.0 0 0.0.0.0 0 IDLE 0.0.0.0 111 0.0.0.0 0 LISTEN 0.0.0.0 0 0.0.0.0 0 IDLE 0.0.0.0 33526 0.0.0.0 0 LISTEN 0.0.0.0 33823 0.0.0.0 0 LISTEN
connstat(1M) also uses the ofmt_set_fs function to change the parsable separator from the default ":" to ",":
cpm@utu ~ % connstat -P -o laddr,lport,raddr,rport,state,mss,outbytes -F laddr=0.0.0.0 0.0.0.0,22,0.0.0.0,0,LISTEN,536,0 0.0.0.0,111,0.0.0.0,0,LISTEN,1220,0 0.0.0.0,0,0.0.0.0,0,IDLE,1220,0 0.0.0.0,111,0.0.0.0,0,LISTEN,536,0 0.0.0.0,0,0.0.0.0,0,IDLE,536,0 0.0.0.0,33526,0.0.0.0,0,LISTEN,536,0 0.0.0.0,33823,0.0.0.0,0,LISTEN,1220,0
ipadm(1M) and dladm(1M) both also rely on ofmt, and should continue to work as they previously have. Here's an example showing them using ofmt for wrapping on commas in output, and also displaying specific fields in both parsable and non-parsable mode, where non-parsable includes the header:
