Hi,
I noticed some wrong outputs when using a punctum mora -- something
like (b.) puts the dot on the line, since in gregoriotex-syllable.tex,
there is this patch:
\def\calculateglyphraisevalue#1#2{%
...
\ifx b#1%
\global\tempcount=\number 2%
%\global\isonaline=1 % temporary (or not) patch, for some complex
reasons (think of a vertical episemus for a c)
\fi%
...
If this is going to be a "somewhat permanent" :-) temporary patch,
then I made this workaround for the \punctummora and \augmentumduplex
macro definitions (looking back though, it may be better for the
visual score output if the punctum mora special case is handled inside
\calculateglyphraisevalue instead, so that the dot's height is
slightly adjusted the same way as for the other lines...):

My actual question is about the augmentum duplex- because there is
wrong output there too. For example, it's too low with (ij..) or
(dgd..). I rewrote the "libgregorio_gregoriotex_write_auctum_duplex"
function in gregoriotex-write.c of my local copy, and the visual score
output produced by GregorioTeX is now correct, but I'm not sure I did
it in a "good" way. Perhaps someone can explain this background
first... Is the augmentum duplex XML property meant to only describe
the specific case of two dots in adjacent spaces? What should
something like this (ei..) be labelled then? Or does "augmentum
duplex" describe any two vertically aligned dots, in which case it's
non-unique, and a little peculiar that it's only a property of one
note, since it needs information from 2 to determine how far apart the
dots are. Am I making sense? :-)
Thanks,
Tracy
