this leaves an additional space between time signature and bar line which I
wanted to avoid using the grace (which has no duration).
I have now found another solution following an idea described here:
http://lists.gnu.org/archive/html/lilypond-user/2009-04/msg00908.html
It overrides the bar-line::calc-glyph-name in output-lib.scm which is
responsible of removing the "||" bar:
======================
\version "2.12.2"
% cribbed from output-lib.scm version 2.12
#(define my-bar-glyph-alist
'((":|:" . (":|" . "|:"))
(":|.|:" . (":|" . "|:"))
(":|.:" . (":|" . "|:"))
("||:" . ("||" . "|:"))
("dashed" . ("dashed" . '()))
("|" . ("|" . ()))
("||:" . ("||" . "|:"))
("|s" . (() . "|"))
("|:" . ("|" . "|:"))
("|." . ("|." . ()))
;; hmm... should we end with a bar line here?
(".|" . ("|" . ".|"))
(":|" . (":|" . ()))
;; ("||" . ("||" . ()))
("||" . ("||" . "||")) ;; allow || at beginning of line
(".|." . (".|." . ()))
("|.|" . ("|.|" . ()))
("" . ("" . ""))
(":" . (":" . ""))
("." . ("." . ()))
("'" . ("'" . ()))
("empty" . (() . ()))
("brace" . (() . "brace"))
("bracket" . (() . "bracket"))
))
#(define (index-cell cell dir)
(if (equal? dir 1) (cdr cell) (car cell)))
#(define (my-calc-glyph-name grob)
(let* (
(glyph (ly:grob-property grob 'glyph))
(dir (ly:item-break-dir grob))
(result (assoc glyph my-bar-glyph-alist))
(glyph-name (if (= dir CENTER)
glyph
(if (and result (string? (index-cell (cdr result) dir)))
(index-cell (cdr result) dir)
#f))))
glyph-name))
{
\new Staff \with {
\override BarLine #'break-visibility = #'#(#t #t #t)
}
{
\override Staff.BarLine #'glyph-name = #my-calc-glyph-name % apply
\time 4/4
%\grace s
%\partial 128 s128
\bar "||"
c''4
}
}
======================
It would be really helpful if one could override the behaviour defined in
'bar-glyph-alist' without having to redefine 'calc-glyph-name'.
