Hi,
there is currently no bookkeeping ('name-->id') for derived colors in mkiv; i.e. \definecolor[foo] [black] does not register 'foo'.
\csname(ca:foo)\endcsname
is the only way to access the color id. While this in no problem in TeX code, using this in lua is not very handy. I tried ugly stuff like
c_id = format("\\csname(ca:%s)\\endcsname",c)
but when I compare 'c_id' with the id of black, the values '1' and 1 (id of black) differ when compared. Mhhhh.
I think that the best way to handle derived colors properly is to add their name to the attributes list too. It's only a small patch and it shouldn't do any harm.
.... I forgot to test the existense of a 'name' :( hopefully now foolprooved. if name then local stra = attributes.list[attributes.numbers['color']][str] if stra then attributes.list[attributes.numbers['color']][name] = stra -- inherit color id else attributes.list[attributes.numbers['color']][name] = attributes.list[attributes.numbers['color']][black] end end
Best wishes, Peter
