<emmanuel`> Hello there!
meh` has joined #nix-lang
<emmanuel`> I was just to make sure that I have this idea correct in my head
<emmanuel`> If only use 1 attribute from an attribute set, I am not forcing the evalution of the entire attribute set? (Assuming of course, that the attribute is independent of the others)

<infinisil> emmanuel`: Attribute sets are strict in keys, but lazy in values
<infinisil> So by accessing one value, you're forcing all attribute keys and only that value
<infinisil> > let attrs = { a = "a"; b = throw "b"; }; in attrs.a
<{^_^}> "a"
<infinisil> So this works, the value of b is not evaluated

<emmanuel`> Ok, I ask this because I want to make sure that a particular build isn't initiated.
