data NExprF r Source #

The main nix expression type. This is polymorphic so that it can be made a functor, which allows us to traverse expressions and map functions over them. The actual NExpr type is a fixed point of this functor, defined below.

Constructors

NConstant !NAtom	Constants: ints, bools, URIs, and null.
NStr !(NString r)	A string, with interpolated expressions.
NSym !Text	A variable. For example, in the expression `f a`, `f` is represented as `NSym "f"` and `a` as `NSym "a"`.
NList ![r]	A list literal.
NSet ![Binding r]	An attribute set literal, not recursive.
NRecSet ![Binding r]	An attribute set literal, recursive.
NLiteralPath !FilePath	A path expression, which is evaluated to a store path. The path here can be relative, in which case it's evaluated relative to the file in which it appears.
NEnvPath !FilePath	A path which refers to something in the Nix search path (the NIX_PATH environment variable. For example, `nixpkgs/pkgs`.
NUnary !NUnaryOp !r	Application of a unary operator to an expression.
NBinary !NBinaryOp !r !r	Application of a binary operator to two expressions.
NSelect !r !(NAttrPath r) !(Maybe r)	Dot-reference into an attribute set, optionally providing an alternative if the key doesn't exist.
NHasAttr !r !(NAttrPath r)	Ask if a set contains a given attribute path.
NAbs !(Params r) !r	A function literal (lambda abstraction).
NApp !r !r	Apply a function to an argument.
NLet ![Binding r] !r	Evaluate the second argument after introducing the bindings.
NIf !r !r !r	If-then-else statement.
NWith !r !r	Evaluate an attribute set, bring its bindings into scope, and evaluate the second argument.
NAssert !r !r	Assert that the first returns true before evaluating the second.

data NString r Source #

An NString is a list of things that are either a plain string or an antiquoted expression. After the antiquotes have been evaluated, the final string is constructed by concating all the parts.

Constructors

DoubleQuoted ![Antiquoted Text r]	Strings wrapped with double-quotes (") are not allowed to contain literal newline characters.
Indented ![Antiquoted Text r]	Strings wrapped with two single quotes ('') can contain newlines, and their indentation will be stripped.

data NKeyName r Source #

A KeyName is something that can appear at the right side of an equals sign. For example, a is a KeyName in { a = 3; }, let a = 3; in ..., {}.a or {} ? a.

Nix supports both static keynames (just an identifier) and dynamic identifiers. Dynamic identifiers can be either a string (e.g.: { "a" = 3; }) or an antiquotation (e.g.: let a = "example"; in { ${a} = 3; }.example).

Note: There are some places where a dynamic keyname is not allowed. In particular, those include:

The RHS of a binding inside let: let ${"a"} = 3; in ... produces a syntax error.
The attribute names of an inherit: inherit ${"a"}; is forbidden.

Note: In Nix, a simple string without antiquotes such as "foo" is allowed even if the context requires a static keyname, but the parser still considers it a DynamicKey for simplicity.

Constructors

DynamicKey !(Antiquoted (NString r) r)
StaticKey !Text
