Functions

func CountLeadingSpaces

func CountLeadingSpaces(line string) int

CountLeadingSpaces counts leading spaces. It's used in checkYamlIndentation() to find indentation error in template.

func Discard

func Discard(slice []interface{}, n interface{}) []interface{}

Discard looks for elements which are not the same and return only unique.

func GetParser

func GetParser(filename string) (func([]byte, template.Template, logger.LoggerInt) (cloudformation.Template, error), error)

GetParser chooses parser based on file extension.

func IsNonStringFloatBool

func IsNonStringFloatBool(v interface{}) bool

IsNonStringFloatBool checks if the element is non-string, non-float64, non-boolean. Then it is another node or <nil>. There is no other option.

func IsPlainMap

func IsPlainMap(mp map[string]interface{}) bool

IsPlainMap checks if map is plain. Plain map means that it's non-nil and it doesn't contain nested maps. It's used in checkWhereIsNil().

func IsPlainSlice

func IsPlainSlice(slc []interface{}) bool

IsPlainSlice checks if slice is plain. Slice is plain if it's non-nil and doesn't contain nested maps. It's used in checkWhereIsNil().

func ParseJSON

func ParseJSON(templateFile []byte, refTemplate template.Template, logger logger.LoggerInt) (template cloudformation.Template, err error)

ParseJSON parses JSON template file to cloudformation template.

func ParseYAML

func ParseYAML(templateFile []byte, refTemplate template.Template, logger logger.LoggerInt) (template cloudformation.Template, err error)

ParseYAML parses YAML template file to cloudformation template.

func PrettyPrintJSON

func PrettyPrintJSON(toPrint interface{}) ([]byte, error)

PrettyPrintJSON prepares JSON file with indent to ease reading it.

func SliceContains

func SliceContains(list []string, a string) bool

SliceContains checks if slice contains given string.
