[Lilypond-auto] [LilyIssues-auto] [testlilyissues:issues] #4590 Document stencil-flip function

[Auto mailings of changes to Lily Issues]

I think this should eventually be handled by some automated documentation mechanism for public scheme functions. Such a mechanism would also document the other functions in /scm/stencil.scm and elsewhere that aren't currently documented.

Here’s a post from David Nalesnik with a script that's a big step in this direction:

http://lists.gnu.org/archive/html/lilypond-user/2015-04/msg00132.html

Seems like a matter of integrating this kind of script into the /scm/documentation-generate.scm file (or a similar, parallel file) so that it would produce a listing like this:

http://lilypond.org/doc/v2.18/Documentation/notation/scheme-functions

(Note: that list is not all Scheme functions, just the C++ functions that are accessible via Scheme.)

But such automated documentation would be a separate issue. So, if there's interest in just documenting stencil-flip here’s an example where it is used to flip the clef glyphs horizontally.

\version “2.19”

\new Staff \with {
\override Clef.stencil = #(lambda (grob)
(flip-stencil X (ly:clef::print grob)))
} {
\clef treble
g'1
\clef bass
g1
}
