vim ultisnip expanding after the line break

Question

I use Ultisnips in vim a lot together with vim-expand:

snippet prg 
!This is file : `!v expand('%:r')`
! Author= `!v expand($USER)`
! Started at: `date +%d.%m.%y`
! 
Program  ${1:`!v expand('%:r')`}
Implicit None
${2:<++Start Typing++>}
End Program  $1
endsnippet

I am facing a problem that, after the ${1:} is expanded in ${1:`!v expand('%:r')`}, if I put a linebreak, the $1 in End Program $1 is picking that up as well; which in NOT intended. To make it clear, here is a screencast: https://www.youtube.com/watch?v=0IjoqWXQNI8

I want to expand and match the first line, but not after linebreak. kindly help.

What you are looking for is something already covered by the screencast for Ultisnips. All you need is regex adjustment to your snippet value $1

Program  ${1:`!v expand('%:r')`}
Implicit None
${2:<++Start Typing++>}
End Program  ${1/([^\n$]+).*/$1/}
endsnippet

${1/([^\n$]+).*/$1/}
        |     |  |
        |     |  +--------Replace by first atom i.e. Matched by (..)
        |     +--------Anything That follows.
        +----------- Match everything except a newline | EOL(endofline)
