Breaking String (Window Path)

Ignition
1

To all Awesome people,
I want to display the name of the Window/ Screen in Header. I have used {[System]Client/User/CurrentWindow} in label expression however it displays full path.
" Folder Name/Folder Name/MM "

How can I make to display just "MM" using expression or script.

Newbie to Ignition.

Thanks

You could easily do it in expression with split().
Alternativily python also has a split function.

fullPath = " Folder Name/Folder Name/MM "
fullPath.split("/")

Both return lists and you will have to grab only the last item in those lists. Expression language should generally be used whenever you can.

try(split({[System]Client/User/CurrentWindow},'/')[len(split({[System]Client/User/CurrentWindow},'/'))-1,0],'')

Note that in designer that tag is blank, that is why I wrapped it in a try.
