Good work. Yes, I think we should. We can use it to avoid unnecessarily
running convert-ly. I do not know whether the LilyPond that we generate
internally is still good for the latest versions of LilyPond - needs
checking, and we need to think about how script generated LilyPond can
be versioned.

Some minor niggles with the code: the value -1 is returned which is not
a double (and will not be converted to one IIRC). Can we not just return
d taking the 0.0 value as indication of failure? then we can pass NULL
instead of endp and not do the check.
And the constant 30 appears twice, making the code fragile - use
#define. One of the functions at least will be static.
I am glad you sorted out the regex stuff - I didn't know it was there.
