Re: Removing the stem engraver?

[Juergen Reuter]

Hi, all!

As I remarked a couple of months ago, I had similar problems with ancient 
notation.  Typographically, to my experience, you will get by far the best 
results by

(1) providing duration-independent notehead selection by patching 
scm/output-lib.scm as follows:

        (if (string-match "vaticana*|hufnagel*|medicaea*" (symbol->string 
style))
           (symbol->string style)


    (This patch provides the default noteheads only (e.g. "\override
    NoteHead #'style = default2"); maybe a generalized version of this
    patch should accept any glyph independent of the notehead duration,
    such that you can do maybe something like:
    "\override NoteHead #'style = always-<glyphname>").

(2) with the above patch, setting the style property of NoteHead to the
    desired head (here, as an example, the quarter note head):

    \override Staff.NoteHead #'style = #'default2

(3) assuming that timing is not used, using durations that do not produce
    stems, i.e. typically whole notes, e.g.:

    \set Score.timing = ##f
    f1 g( a) f( d) f( g f1.)

I do recognize that this approach is not much less dirty than the 
other workarounds that have been suggested so far (e.g., as a side effect, 
midi timing may not necessarily be what you would like to get), but for 
meterless music, it gives you at least typographically exactly what you 
want, afaics.  And you do not have at all to fight / do tricks with the 
stem engraver, beams, etc. -> your .ly file remains human-readable!

Greetings,
Juergen
