Issue 514: abc2ly grace notes
http://code.google.com/p/lilypond/issues/detail?id=514
Comment #1 by gpermus:
More abc2ly grace note unhappiness:
This problem arises when generating .ly files using "abc2ly
--beams=None" (version
2.11.34), which generate mismatch beaming "[" and \grace{...}. When
LilyPond compiles
this file, the grace notes will be replaced by 1/4 pointing the wrong
way, and will
further also on grace notes further down which are syntactically
correct. So LilyPond
has not only a a problem of not being able to generate a decent output
given the
syntax error, but also cannot recover properly from the error.
An ABC source file

M:C
L:1/8

{ga}gdgb {a}g>d g<a|
compiled using "abc2ly --beams=None" generates code of the form
...
\grace { gis''8[ a''8 } gis''8 dis''8
gis''8 b''8] \grace { a''8 } gis''8.[ dis''16] gis''16[
a''8.]
...
Here, the first "[" within the \grace{...} construct does not have a closing
"]".
However, the code is after is closing "]" correct. But also the second
\grace{...}
gets a funny putout. It looks as in the attachment.
