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

Enumerations
enum class	nixd::FindAttrPathResult { nixd::OK , nixd::Inherit , nixd::NotAttrPath , nixd::WithDynamic }

Functions
Selector	nixd::idioms::mkVarSelector (const nixf::ExprVar &Var, const nixf::VariableLookupAnalysis &VLA, const nixf::ParentMapAnalysis &PM)
	Construct a nixd::Selector from Var.
Selector	nixd::idioms::mkSelector (const nixf::AttrPath &AP, Selector BaseSelector)
	Construct a nixd::Selector from AP.
Selector	nixd::idioms::mkSelector (const nixf::ExprSelect &Select, Selector BaseSelector)
	Construct a nixd::Selector from Select.
Selector	nixd::idioms::mkSelector (const nixf::ExprSelect &Select, const nixf::VariableLookupAnalysis &VLA, const nixf::ParentMapAnalysis &PM)
	Construct a nixd::Selector from Select.
const nixf::EnvNode *	nixd::upEnv (const nixf::Node &Desc, const nixf::VariableLookupAnalysis &VLA, const nixf::ParentMapAnalysis &PM)
	Search up until there are some node associated with "EnvNode".
bool	nixd::havePackageScope (const nixf::Node &N, const nixf::VariableLookupAnalysis &VLA, const nixf::ParentMapAnalysis &PM)
	Determine whether or not some node has enclosed "with pkgs; [ ]".
std::pair< std::vector< std::string >, std::string >	nixd::getScopeAndPrefix (const nixf::Node &N, const nixf::ParentMapAnalysis &PM)
	get variable scope, and it's prefix name.
FindAttrPathResult	nixd::findAttrPath (const nixf::Node &N, const nixf::ParentMapAnalysis &PM, std::vector< std::string > &Path)
	Heuristically find attrpath suitable for "attrpath" completion.

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