Functions ¶

func ErrorMessage ¶

func ErrorMessage(v any) string

ErrorMessage extracts the error string from a canonical-data.json error object. Error objects have the form {"error": "some message"}. Returns "" if v is not an error object or contains no error string.

func FloatSliceToInts(v any) []int

FloatSliceToInts converts a JSON-decoded []any of float64 values to []int. Returns nil if v is not a []any or if any element is not a float64.

func Gen ¶

func Gen(exercise string, tests map[string]interface{}, t *template.Template) error

Gen generates the exercise cases_test.go file from the relevant canonical-data.json

func IsError ¶

func IsError(v any) bool

IsError reports whether v is a canonical-data.json error object (i.e., {"error": "..."}).

func PackageName ¶
