Resistor Color Trio output format unclear

Programming Red
1

I am attempting the Resistor Color Trio exercise in the Red track. In the test script, the first test says this:

  16   │     expected: #(
  17   │         value: 33
  18   │         unit: "ohms"
  19   │     )

and I can’t, for the life of me, figure out how it wants those values returned. My function correctly calculates 33 ohms, but I have tried returning

make object! [
    value: 33
    unit: "ohms"
]

and

make map! ["value" 33 "unit" "ohms"]

and even in desperation the string “33 ohms” (like the text of the exercise suggests), but none of these satisfy the test script.

Does anyone have any suggestions for how I should format my output?

This link looks relevant: docs/map.adoc at master · red/docs · GitHub

Looks like you don’t want to use a string for the key.

I think a common implementation is to return a string.

return sprintf("%d %s", value, unit);

But each track can interpret that data however they decide!

This did it! Thank you so much.

NB for future searchers: The elements of the list passed to make map! aren’t evaluated, so ended up having to do this:

resistance: ...etc

m: make map! []
m/value: resistance
m/unit: "ohms"

The docs indicate to me that this might be valid:

make map! [value 33 unit "ohms"]
