Overview ¶

Package respfmt renders a JSON response body through an optional JMESPath projection and one of five output formats: yaml (default),

Functions ¶

func Eval ¶

func Eval(data any, expr string, vars map[string]any) (any, error)

Eval evaluates expr against decoded data, with vars injected as native `$name` variables (keys are bare names; Eval adds the `$`). See specverb-actions.md.

func EvalBool ¶

func EvalBool(data any, expr string, vars map[string]any) (bool, error)

EvalBool evaluates expr and reports its JMESPath truthiness, the predicate form `until` and `fail-when` need. A non-boolean result is reduced via Truthy.

func Render ¶

func Render(raw []byte, query, output string) ([]byte, error)

Render applies the optional JMESPath projection to raw and formats the result per output. Empty raw returns empty bytes, no error. Empty query

func Truthy ¶

func Truthy(v any) bool

Truthy reports JMESPath truthiness: null, false, "", [], and {} are false; everything else (including the number 0) is true, per the JMESPath spec.

func Validate ¶

func Validate(expr string) error

Validate reports whether expr parses as JMESPath, without evaluating it: the build-time check that fails closed on a malformed `until`/`fail-when`.
