nixd::idioms Namespace Reference

Classes
struct	DynamicNameException
	The attrpath has a dynamic name, thus it cannot be trivially transformed to "static" selector. More...
struct	IdiomException
struct	IdiomSelectorException
	Exceptions scoped in nixd::mkIdiomSelector. More...
struct	NoLocationForBuiltinVariable
struct	NoSuchVarException
	No such variable. More...
struct	NotAnIdiomException
	The pattern of this variable cannot be recognized by known idioms. More...
struct	NotVariableSelect
struct	UndefinedVarException
struct	VLAException

Functions
Selector	mkVarSelector (const nixf::ExprVar &Var, const nixf::VariableLookupAnalysis &VLA, const nixf::ParentMapAnalysis &PM)
	Construct a nixd::Selector from Var.
Selector	mkSelector (const nixf::AttrPath &AP, Selector BaseSelector)
	Construct a nixd::Selector from AP.
Selector	mkSelector (const nixf::ExprSelect &Select, Selector BaseSelector)
	Construct a nixd::Selector from Select.
Selector	mkSelector (const nixf::ExprSelect &Select, const nixf::VariableLookupAnalysis &VLA, const nixf::ParentMapAnalysis &PM)
	Construct a nixd::Selector from Select.

Variables
constexpr std::string_view	Pkgs = "pkgs"
	Hardcoded name for "pkgs.xxx", or "with pkgs;".
constexpr std::string_view	Lib = "lib"
	Hardcoded name for nixpkgs "lib".

Variable Documentation

Lib

std::string_view nixd::idioms::Lib = "lib"

inlineconstexpr

Hardcoded name for nixpkgs "lib".

Assume that the value of this variable is "nixpkgs lib". e.g. lib.genAttrs.

Definition at line 26 of file AST.h.

Pkgs

std::string_view nixd::idioms::Pkgs = "pkgs"

inlineconstexpr

Hardcoded name for "pkgs.xxx", or "with pkgs;".

Assume that the value of this variable have the same structure with `import nixpkgs {}
