Hi Petri,
PK> Is there any way i can use variables in pen command?
PK> pen (r.g.b)
PK> There is no to-color function?
What a great question! You found a solution, and Tom gave you another,
but it prompted me to think about interpolation a bit. It's come up a
few times over the years, but I haven't seen it in the context of
tuples.
tup: func [ ; tupify? ;)
'tuple [word!]
/local words
][
words: parse form tuple "."
forall words [change/only words to word! first words]
to tuple! reduce words
]
r: 0
g: 128
b: 255
print tup r.g.b
set [a b c d e f g h i j] [1 2 3 4 5 6 7 8 9 10]
print tup a.b.c.d.e.f.g.h.i.j
Quick and dirty to be sure, but it might also be handy.
Questions:
What would be a good name for this?
Should it just error out if you give it an invalid argument? That is a
word in the tuple that refers to a non-integer value.
