Overview

In [[Nix]], [[key-value-pair|key-value-pairs]] go by name-value-pairs.

Structure

• Key: The key in [[Nix]] doesn't have to be a string.
• Separator: Values are assigned to a value with an equal sign (=).
• Value: Values can be any [[primitive-data-types|primitive data types]], [[functions]], or [[attribute-sets|attribute sets]], or [[lists]].
• Delimiter: name-value-pairs in a set are delimited by a semicolon (;)

example structure

{name}{separator}{value}{delimier}

name = "value";

{
  a = "string";
  b = 20;
  c = true;
  d = ./path/to;
  e = ["list" 10 true];
  f = {
    name = "value";
    attribute = true;
  };
}

Assigning names to values

Names can be assigned to values in a number of ways:

• [[attribute-sets|Attribute sets]] { ... }
• [[let-bindings|Let bindings]] let ... in
• [[functions|Functions]] :
