func Assign ¶

func Assign(target map[string]interface{}, selector string, value interface{}) error

Assign writes a value into the provided JSON-like map using the same selector syntax supported by Select, but without the input/output prefix. Missing object segments are created automatically. Array writes are only supported when the indexed segment already exists.

func Select ¶

func Select(selector string, input, output interface{}) interface{}

Select resolves a value from either the input or output JSON-like roots (maps/slices produced by json.Unmarshal) based on a dot/bracket selector.

Supported prefixes:

• "output" (default when no prefix is provided)
• "input"

Supported path syntax:

• dot-separated keys: a.b.c
• array indices: a.0.b or a[0].b

When a path segment cannot be resolved the function returns nil.
