In the last 3 weeks I created the base for an R5RS Scheme interpreter
written in Java, aimed at GUILE compatibility. It is quite basic yet,
but I'm not very far from the point where I can start interpreting
LilyPond input files as they are. Actually module support is what I have
to implement until that.
Cool! Just as curiosity, why didn't you consider the alternate
Java-schemes, like jscheme, kawa, sisc, etc?
There are some reasons.
- I found their architecture to be too complicated. I wanted a simple,
clean one.
- Their code base seem to be written in not Java style.
- If I need some ideas I can get from them.
- They have their own extensions which may collide with the guile stuff.
- My motivation was stronger this way.
Still, writing my own version may be a wrong idea. However, for
extending it with guile constructs I still feel it easier, because of
their complexity, legacy extensions I'd be afraid of making a change in
the code would create unexplicable behaviour.
It depends on how far you want to go. It is easy to extract signatures
(names & number of arguments) automatically.
That's a good idea. That way I can generate stubs.
Surely you don't want to reimplement all of LilyPond in Java?
No I don't. My goals are:
- have bar checks work really as bar checks (using Duration objects etc.)
- have autocompletion in Scheme
- perhaps some visual display of music written - I don't know how
feasible is this without implementing all of LilyPond in Java
