3 # ly2dvi.py -- Run LilyPond, add titles to bare score, generate printable
5 # Invokes: lilypond, latex (or pdflatex), dvips, ps2pdf, gs
7 # source file of the GNU LilyPond music typesetter
9 # (c) 1998--2002 Han-Wen Nienhuys <hanwen@cs.uu.nl>
10 # Jan Nieuwenhuizen <janneke@gnu.org>
12 # This is the third incarnation of ly2dvi.
14 # Earlier incarnations of ly2dvi were written by
15 # Jeffrey B. Reed<daboys@austin.rr.com> (Python version)
16 # Jan Arne Fagertun <Jan.A.Fagertun@@energy.sintef.no> (Bourne shell script)
19 # Note: gettext work best if we use ' for docstrings and "
20 # for gettextable strings.
21 # --> DO NOT USE ''' for docstrings.
27 * figure out which set of command line options should make ly2dvi:
30 na: create latex only?
31 na: create tex and latex
32 default: create dvi only
33 na: create tex, latex and dvi
40 * for foo.ly, rename ly2dvi.dir to out-ly2dvi, foo.ly2dvi, foo.dir ?
42 * move versatile taglines,
45 beginfooter=\mutopiaPD
46 endfooter=\tagline -> 'lily was here <version>'
49 lilytagline (->lily was here), usertagline, copyright, lily-version
52 * head/header tagline/endfooter
54 * dvi from lilypond .tex output? This is hairy, because we create dvi
55 from lilypond .tex *and* header output.
57 * multiple \score blocks?
59 * Introduce verbosity levels
61 0 = QUIET: mute all command output, no ly2dvi progress
62 1 = BRIEF: mute all command output, only ly2dvi progress
63 2a = NORMAL: show only LilyPond command output, show ly2dvi progress
64 2b = NORMAL: show command output, show ly2dvi progress
65 3 = VERBOSE: show command output, run lilypond --verbose
66 4 = DEBUGGING: show all command output, run lilypond --verbose, print
67 environment and all kinds of client side debugging stuff
69 Currently, we only have 1 and 4, but we kludge to have 2a and 4.
