Detailed Description

A "derived path" is a very simple sort of expression (not a Nix language expression! But an expression in a the general sense) that evaluates to (concrete) store path. It is either:

opaque, in which case it is just a concrete store path with possibly no known derivation
built, in which case it is a pair of a derivation path and an output name.

Member Function Documentation

◆ getBaseStorePath()

const StorePath & nix::SingleDerivedPath::getBaseStorePath ( ) const

Get the store path this is ultimately derived from (by realising and projecting outputs).

Note that this is not a property of the store object being referred to, but just of this path — how we happened to be referring to that store object. In other words, this means this function breaks "referential transparency". It should therefore be used only with great care.

◆ parse()

SingleDerivedPath nix::SingleDerivedPath::parse	(	const Store &	store,
		std::string_view	s,
		const ExperimentalFeatureSettings &	xpSettings = experimentalFeatureSettings )

static

Uses ^ as the separator

Parameters

xpSettings Stop-gap to avoid globals during unit tests.

◆ parseLegacy()

SingleDerivedPath nix::SingleDerivedPath::parseLegacy	(	const Store &	store,
		std::string_view	s,
		const ExperimentalFeatureSettings &	xpSettings = experimentalFeatureSettings )

static

Uses ! as the separator

Parameters

xpSettings Stop-gap to avoid globals during unit tests.

◆ to_string()

std::string nix::SingleDerivedPath::to_string ( const Store & store ) const

Uses ^ as the separator

◆ to_string_legacy()

std::string nix::SingleDerivedPath::to_string_legacy ( const Store & store ) const

Uses ! as the separator
