-- is an articulation, not a separate event, so you need to write
The peo ^\tweak ,,, --
Note that there is no way around using ^ to indicate the \tweak being a
post-event: the problem is that postevents are parsed differently from
straight music, so LilyPond first needs to decide it is going to make
straight music or a postevent, and the neutral direction indicator - has
a different meaning in lyrics. You can do one of the following:
{ \repeat unfold 4 c'16 }
\addlyrics { The peo
^\tweak #'minimum-distance #14 -- ple that }
postweak =
#(define-event-function (parser location grob path val ev)
((string? *unspecified*) list-or-symbol? scheme? ly:event?)
#{ \tweak $grob #path #val $ev #})
{ \repeat unfold 4 c'16 }
\addlyrics { The peo
\postweak LyricHyphen #'minimum-distance #14 -- ple that }
Neither is really pretty. At one time I hope to be able to unify the
parsing of event and music function arguments: then one could first
evaluate the function, _then_ decide whether it is a post-event or not.
