Redefining barline command

[Nils Gey]

Hello Lilyponds,

I want to redefine (advanced version: only for the current movement) that 
everytime I use \bar "|." instead, internaly, this should be used:

\once \override Score.BarLine #'transparent = ##f   \bar "|."

How can I do this?


Background: I deactivated barlines to get a mensural output. This deactivates 
the final, closing, barline, too. |. 
The transparent == ##t override can be placed in the movements layout block 
which is fine because its valid only for one movement. But how do I get the 
final barline back without placing the directive inside of a staff? A staff can 
be deleted and the instruction would be lost.

My solution is to override the |. bar to be drawn over the complete staff. 

Maybe there is a better solution to place \revert Score.BarLine #'transparent  ?

Greetings, 

Nils
