Comment #8 on issue 3487 by [email protected]: Patch: Make several special
characters with or without backslash "non-special"
http://code.google.com/p/lilypond/issues/detail?id=3487
For casual reviewers: let me point out more explicitly that this patch
series makes _two_ syntax changes that appear mostly unrelated to the patch
itself (the relation is by technical necessity).
Those two changes are
a) that the shorthand for staccatissimo becomes -! instead of -| as
currently. Taking aside the technical necessity because of | being freely
definable including as a postevent, and thus not visible as a _character_
to the parser, I find that shorthand making a lot more sense than the
previous one, in particular given that -. already is staccato. So I am
pretty convinced that this change would be able to survive on its merits
alone.
b) that \tempo 4. = 60 ~ 62 becomes \tempo 4. = 60 - 62 instead. That's
not terribly fabulous, and I am particularly considering _not_ permitting -
into REAL tokens at all. At the current point of time, writing \tempo 4. =
60-62 (namely without a space between - and 62) inside of a \midi block
will likely cause trouble.
~ was actually a rather insane character here, and indeed, the whole \tempo
syntax is nothing to be proud of.
On their own, those changes probably make some sort of sense in a
low-priority way. But they are required to make this issue fly.
The value of this issue is mainly removing hardwired semantics and making
it easier for people to experiment with extending and/or redefining various
details of the syntax.
