This is an interesting idea. For boolean knobs, I'd really like to see us use the NetBSD way: # checkyesno var # Test $1 variable, and warn if not set to YES or NO. # Return 0 if it's "yes" (et al), nonzero otherwise. # checkyesno() { eval _value=\$${1} debug "checkyesno: $1 is set to $_value." case $_value in # "yes", "true", "on", or "1" [Yy][Ee][Ss]|[Tt][Rr][Uu][Ee]|[Oo][Nn]|1) return 0 ;; # "no", "false", "off", or "0" [Nn][Oo]|[Ff][Aa][Ll][Ss][Ee]|[Oo][Ff][Ff]|0) return 1 ;; *) warn "\$${1} is not set properly." return 1 ;; esac } To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
