Functions

func GetFuncMap

func GetFuncMap(failMessage *string) template.FuncMap

GetFuncMap returns the list of functions provided by sprig. It changes the function "fail" to set the given string, this way we can report template errors directly to the template without having the wrapper that text/template adds.

sprig "env" and "expandenv" functions are removed to avoid the leak of information.

func ValidateTemplate

func ValidateTemplate(data []byte) error

ValidateTemplate validates a text template results in valid JSON when it's executed with empty template data. If template execution results in invalid JSON, the template is invalid. When the template is valid, it can be used safely. A valid template can still result in invalid JSON when non-empty template data is provided.

func ValidateTemplateData

func ValidateTemplateData(data []byte) error

ValidateTemplateData validates that template data is valid JSON.
