As far as I understand, then the toc-tems are stored in a list as soon
as they are seen by the parser.
The (simplified) list for your example would then look like
(list "PART B" "PART A")
The table-of-contents-markup-list-command works on this list in the
order the entries appear. Though, the page-numbers are assigned and
inserted with delay, _after_ the pages are calculated, i.e. at the
very end of compilation.
Thus you can't go back and reorder the table-of-content. Resulting in
(usually) correct assignmens but appearing in unwanted order (at least
in your example).
Though, you can reorder the toc-items _before_ table-of-contents work on it.
For your example one could do:
partB =
\bookpart {
\tocItem "PART B"
\new Staff {
c4 d e f
}
}
partA =
\bookpart {
\tocItem "PART A"
\new Staff {
c4 d e f
}
}
%% Reorder (toc-items):
%% To be done after all \tocItem-stuff is done and before table-of-contents is
%% called
#(let ((t-i (toc-items)))
;;;; (1)
;;;; watch the original toc-items:
;(write t-i)
;;;; (2)
;;;; reset the list, be aware: needs to be a procedure!
;;;; (2a)
;; doing it manually for each entry:
;(set!
; toc-items
; (lambda ()
; (list
; (second t-i)
; (first t-i))))
;;;; (2b)
;; in the simple example a reverse would do it already;
;(set!
; toc-items
; (lambda () (reverse t-i)))
;
;;;; (2c)
;; reorder alphabetical
(set!
toc-items
(lambda () (sort t-i (lambda (p q) (string-ci<? (last p) (last q))))))
;;;; (3)
;;;; watch the result
;(write (toc-items))
)
\book {
\bookpart {
\markuplist \table-of-contents
\paper {
tocTitleMarkup = \markup \center-column {
\italic "Contents"
\vspace #0.3
}
tocItemMarkup = \markup {
\fill-with-pattern
#1 #RIGHT " . "
\fromproperty #'toc:text
\fromproperty #'toc:page
}
}
}
\bookpart { \partA }
\bookpart { \partB }
}
Also, look at:
http://lsr.di.unimi.it/LSR/Item?id=763
For personal use I made some other codings of this kind, shout if interested.
They all reorder the toc-items for different use-cases.
