You could use regexp maybe.
"resource:core/math/math.factor" utf8 file-contents
R/ USING:(\s+[^;]+)+\s+;/ all-matching-subseqs
[ "USING:" ?head drop ";" ?tail drop " " split harvest ] map concat
We have the using list available at parse time but I don't think it's
stored anywhere in the vocab thats created.
Usually the USING: list is pretty much everything, but some other forms are
used occasionally that you might want to also parse to have the fullest
picture:
USE: vocab
UNUSE: vocab
FROM: vocab => words ... ;
EXCLUDE: vocab => word ... ;
QUALIFIED: vocab
QUALIFIED-WITH: vocab name
Also, you vocabs and their private vocab maybe should be merged:
[ ".private" ?tail drop ] map members
