A work-in-progress guide to extending LilyPond

[Jean Abou Samra]

Hi,

A frequent complaint on this list is the lack
of available documentation about LilyPond's
inner workings and programming interfaces.

Indeed, I have myself experienced the thorny
path to getting a grasp of how to extend
LilyPond in Scheme.

To remedy this, pushed by Jacques, I wrote
up the start of something that could someday
resemble an introduction to extending and a
guide covering programming topics. It is a
work-in-progress and pretty incomplete at the
moment. Nevertheless, it contains some unique
material, like the explanations about Scheme
engravers (totally undocumented).

On the long-term, this might make its way into
the official documentation in an adapted form.

It's here:

I'll be glad if this is useful to someone.

I would also appreciate any comments you
might have.

Regards,
Jean
