Re: Special bar lines

[Br. Samuel Springuel]

Whoops.  Spoke to soon.  I have some scores where I have these special 
bar lines and either "|." or ":|." and when made in a universal manner, 
these overrides affect them as well (in both the thick line is thinned, 
in ":|." the dots are also reduced in size).

Is there a way to change these settings so that they only affect the "[" 
and "]" bar lines and not anything else?

I've thought about using \temporary ... \revert and \once to affect just 
the barlines I want, but these create more edits (which to some extent 
can be automated via sed).  I'm hoping for a solution which will be easy 
to apply on a project wide basis by adding it to the project style file 
(which all project files include).

My experimentation:
%%%%%%%%%%%%
\version "2.19.53"

% extra bar lines (optional bars)
\defineBarLine "[" #'("" "[" "")
\defineBarLine "]" #'("]" "" "")

optBarOpen = { \once \override  Staff.BarLine.thick-thickness = 2 \once 
\override  Staff.BarLine.font-size = #-4 \bar "[" }
optBarClose = { \once \override  Staff.BarLine.thick-thickness = 2 \once 
\override  Staff.BarLine.font-size = #-4 \bar "]" }


music = {
    % in order to apply the overrides to just the barlines I'm 
interested in
    % I need to make them temporary and revert them
    c' \temporary \override  Staff.BarLine.thick-thickness = 2 
\temporary \override  Staff.BarLine.font-size = #-4 \bar "["
    c' c' \bar "]"  c' \revert Staff.BarLine.thick-thickness \revert 
Staff.BarLine.font-size c' \bar "|" c' c' \bar ":|." c'
    % I can also use \once, which has the advantage of being easier to
    % separate out into a function
    c' \optBarOpen c' c' c' \optBarClose c' c' c' \bar "|."
}

\layout {
    \context {
        \Staff
        % these universal overrides also affect the ":\." bar and thus
        % are no good, but they are the easiest to apply project wide
        % because they require that only the project style file be editted
        %\override  BarLine.thick-thickness = 2
        %\override  BarLine.font-size = #-4
    }
}

\new Staff
{
    \new Voice = "mel" { \music }
}
