This post is helpful for configuring emacs to automatically update the “Serial” in bind zone databases. I wanted to do the same in Vim, but the solutions in the comments of that post didn’t work for me. Here’s a version that does. It’s yours for free under the Affero GPL v3 (or any later version, at your preference):
function s:BindZoneSettings() function s:UpdateBindZoneSerial(date, num) if (strftime("%Y%m%d") == a:date) return a:date . a:num+1 endif return strftime("%Y%m%d") . '01' endfunction function s:ReplaceBindZoneSerialLine() :%s/\(2[0-9]\{7}\)\([0-9]\{2}\)\(\s*;\s*Serial\)/\=UpdateBindZoneSerial(submatch(1), submatch(2)) . submatch(3)/g endfunction autocmd BufWritePre /etc/bind/db.* call ReplaceBindZoneSerialLine() endfunction
