For a while, some of us have been wanting to generate the
valid music-function type-predicates automatically. I tried
something but got stuck almost immediately. I don't know if
this is the right approach, but by adding these two scheme
definitions just after the (set! type-p-name-alist ...)
block in scm/lily.scm, a texinfo string is stored in the
scheme variable "typecheck-doc-table".
For the scheme code below, I added a space after any
double-quote that is immediately followed by an at-sign (to
sidestep the annnoying addr...@hidden archive mangling).
Though in the attached patch, I didn't add these spaces.
Also, the columns in the table are reversed for now, since
type-p-name-alist is sorted by predicate (not by the
description docstring). I'll either need to modify the
(make-doc-typecheck-row ...) procedure so that the columns
are switched, or reword the doc sentences leading up to the
table (neither is a big problem).
The question is, is this the right approach? Is there a way
for the texinfo doc files to access the typecheck-doc-table
string so that that the table appears as if it were inline
texinfo?
Thanks.
