Used vim in linux to edit the files. Hopefully didnt create a mess.

lol, thanks :}

I did change it to always show on webpage though, if showstaticfields is on

learning to use github effectively, still a learning from googling.

check out core.autocrlf = auto, it keeps whitespaces same as repo
Also checkout github desktop, I use it alot when I am remote or do not feel like installing git, if you are not already using it

So if the user only specifies ip, gw and sn, then the DNS will still pop up in the web interface. That's why I set it as optional, else we got to edit the readme that DNS is mandatory.

[tablatronix]

Why would it be mandatory, it can be blank, the problem is showstaticfields and if staticip tied togsther, i might add a more detailed customization option to flag each one regardless of custom or not

[tablatronix]

Showstaticfields ip,gw,sn,dns bool, or maybe three state int 0,1,2 show always, show if set, show never

[tablatronix]

Maybe just 2 toggles, ip and dns, if you enable staticip you probsbly always want gw and sn also always

[debsahu]

Exactly, static IP with and without dns.
