MarshalWithJSONPB returns a YAML string representation of val (using jsonpb).
OverlayIOP overlays over base using JSON strategic merge.
func OverlayTrees(base map[string]interface{}, overlays ...map[string]interface{}) (map[string]interface{}, error)
OverlayTrees performs a sequential JSON strategic of overlays over base.
OverlayYAML patches the overlay tree over the base tree and returns the result. All trees are expressed as YAML strings.
ParseValue parses string into a value
PathKV returns the key and value string parts of the entire key/value path element. It returns an error if pe is not a key/value path element.
PathN returns the index part of the entire value path element. It returns an error if pe is not an index path element.
PathV returns the value string part of the entire value path element. It returns an error if pe is not a value path element.
func ReadFilesWithFilter(path string, filter FileFilter) (string, error)
ReadFilesWithFilter reads files from path, for a directory it recursively reads files and filters the results for single file it directly reads the file. It returns a concatenated output of all matching files' content.
RemoveBrackets removes the [] around pe and returns the resulting string. It returns false if pe is not surrounded by [].
RenderTemplate is a helper method to render a template with the given values.
SetLabel is a helper function which sets the specified label and value on the specified object.
StringBoolMapToSlice creates and returns a slice of all the map keys with true.
ToIntValue returns 0, false if val is not a number type, otherwise it returns the int value of val.
ToString returns a string representation of errors, with elements separated by separator string. Any nil errors in the slice are skipped.

ToYAMLPathString converts a path string such that the first letter of each path element is lower case.
ToYAMLWithJSONPB returns a YAML string representation of val (using jsonpb), or the error string if an error occurs.
UnmarshalWithJSONPB unmarshals y into out using gogo jsonpb (required for many proto defined structs).
UpdateSlicePtr updates an entry at index in the parent, which must be a slice ptr, with the given value.
ValuesAreSameType returns true if v1 and v2 has the same reflect.Type, otherwise it returns false.
Errors is a slice of error.
AppendErr appends err to errors if it is not nil and returns the result. If err is nil, it is not appended.
AppendErrs appends newErrs to errors and returns the result. If newErrs is empty, nothing is appended.
NewErrs returns a slice of error with a single element err. If err is nil, returns nil.
Dedup removes any duplicated errors.
Error implements the error#Error method.
String implements the stringer#String method.
ToError returns an error from Errors.
