func Expr(cfg *Config, r adt.Runtime, pkgPath string, x ast.Expr) (adt.Conjunct, errors.Error)
Expr compiles the given expression into a conjunct. The pkgID must be a unique identifier for a package in a module, for instance as obtained from build.Instance.ID.
func Files(cfg *Config, r adt.Runtime, pkgID string, files ...*ast.File) (*adt.Vertex, errors.Error)
Files compiles the given files as a single instance. It disregards the package names and it is the responsibility of the user to verify that the packages names are consistent. The pkgID must be a unique identifier for a package in a module, for instance as obtained from build.Instance.ID.
Files may return a completed parse even if it has errors.
func LookupRange(name string) adt.Expr
LookupRange returns a CUE expressions for the given predeclared identifier representing a range, such as uint8, int128, and float64.
Config configures a compilation.
type Config struct {
// Scope specifies a node in which to look up unresolved references. This
// is useful for evaluating expressions within an already evaluated
// configuration.
Scope Scope
// Imports allows unresolved identifiers to resolve to imports.
//
// Under normal circumstances, identifiers bind to import specifications,
// which get resolved to an ImportReference. Use this option to
// automatically resolve identifiers to imports.
Imports func(x *ast.Ident) (pkgPath string)
// contains filtered or unexported fields
}
A Scope represents a nested scope of Vertices.
type Scope interface {
Parent() Scope
Vertex() *adt.Vertex
