Functions ¶

func Apply ¶

func Apply(path *PathExpr, obj, value any) error

Apply applies a mutation i.e. sets the value(s) referred to by the path expression. Missing or nil values in the path will not be created, and will cause an error.

Types ¶

type Op ¶

type Op struct {
	Path      *PathExpr
	Condition cel.Program
	Value     any
}

Op is an operation that conditionally assigns a value to a path within an object. Designed to be sent over the wire as JSON.

func (*Op) Apply ¶

func (o *Op) Apply(ctx context.Context, current, mutated *unstructured.Unstructured) error

Apply applies the operation to the "mutated" object if the condition is met by the "current" object.

func (*Op) UnmarshalJSON ¶

func (o *Op) UnmarshalJSON(data []byte) error

type PathExpr ¶

type PathExpr struct {
	// contains filtered or unexported fields
}

PathExpr represents an expression that can be used to access or modify values in a nested structure.

func ParsePathExpr ¶

func ParsePathExpr(expr string) (*PathExpr, error)

ParsePathExpr parses a path expression string.

Supported syntax: - `field.anotherfield`: object field traversal - `field[2]`: array indexing - `field[*]`: array wildcards - `field[someKey="value"]`: object array field matchers

Expressions can be chained, e.g. `field.anotherfield[2].yetAnotherField`.
