Using VimScript functions inside Xvim??

[ghost]

Description

Trying to use a vim function (located inside my .xvimrc)
Function Constr(cs)
if a:cs == "cx"
return "centerXAnchor"
"etc. etc.
endif
endfunction

Operation

So I hate typing up constraints. It kills me every single day.

1. So lets say I have two characters that represent "centerXAnchor" with "cx"
2. in EX mode, I do this ":s/ .\+ /=Constr(submatch(0))/g"

Note: Constr(cs) is a vimscript function (inside .xvimrc) that takes two character strings, goes through if-else statements to return the appropriate NSLayoutConstraint variable. So "ta" return "topAnchor"

Expected behaviour

Nothing happens when I run this. Ex command goes blank, and the text isn't changed.

Environments

• Xcode Version [ 8.3.2 ]
• XVim branch and revision [ developer i think? ]
• Keyboard Language [ QWERTY ]
• Input source language [ what... ]

Is it possible to add this functionality?
