Types

type ErrNoTable

type ErrNoTable error

ErrNoTable indicates that a chart does not have a matching table.

type ErrNoValue

type ErrNoValue error

ErrNoValue indicates that Values does not contain a key with a value

type Values

type Values map[string]interface{}

Values represents a collection of chart values.

func ReadValues

func ReadValues(data []byte) (vals Values, err error)

ReadValues will parse YAML byte data into a Values.

func ReadValuesFile

func ReadValuesFile(filename string) (Values, error)

ReadValuesFile will parse a YAML file into a map of values.

func (Values) AsMap

func (v Values) AsMap() map[string]interface{}

AsMap is a utility function for converting Values to a map[string]interface{}.

It protects against nil map panics.

func (Values) PathValue

func (v Values) PathValue(ypath string) (interface{}, error)

PathValue takes a path that traverses a YAML structure and returns the value at the end of that path. The path starts at the root of the YAML structure and is comprised of YAML keys separated by periods. Given the following YAML data the value at path "chapter.one.title" is "Loomings".

chapter:
  one:
    title: "Loomings"

func (Values) Table

func (v Values) Table(name string) (Values, error)

Table gets a table (YAML subsection) from a Values object.

The table is returned as a Values.

Compound table names may be specified with dots:

foo.bar

The above will be evaluated as "The table bar inside the table foo".

An ErrNoTable is returned if the table does not exist.

func (Values) YAML

func (v Values) YAML() (string, error)

YAML encodes the Values into a YAML string.
