how do I make a map like the following?

it is the result of adding 2 maps together .... mapA is a mapOf<String,AnsiColor>() and mapB<String,AnsiColor> needs to be mapped from set1<String> in the way that mapB entries are constructed from set1 String element to AnsiColor.GREEN (this is a constant)

Hi @Dalinar, I'm not entirely sure what you are attempting to do, maybe if you try to describe it in code even if it does not compile the intention may be a bit more clear. In whatever case I would start by trying mapA.toList().zip(mapB.toList()) { //transform here } or similar

[Dalinar]

my main problem is just that i'm rusty on functional kotlin - maybe you could just suggest some possible extension funs to use and then I could figure out what to do?

[Dalinar]

I have a map of hardcoded substrings that I assign colors to.. I want to enhance this map with another bunch (set) of strings that all map to the same color - for use with debugging.. so I want to combine this set and the main map together into one big map

[Dalinar]

so like

"abc" to AnsiColor.Blue,
"def" to AnsiColor.Red

add this with all from set

"ghi", "jkl", "mno"
they all will use AnsiColor.Green, so that is why we only need a set here - not a map

like

"ghi" to AnsiColor.Green,
"jkl" to AnsiColor.Green,
"mno" to AnsiColor.Green

[Dalinar]

so final map has 5 entries, a Blue, a Red and 3 greens with their respective strings

ok, I think I get what you mean now. I will reply in the main channel with a code snippet

great, thanks
