Functions

func HasTemplating added in v0.48.0 

func HasTemplating(node yamlmeta.Node) bool

func NewGoValueWithYAML added in v0.48.0 

func NewGoValueWithYAML(val interface{}) tplcore.GoValue

func NewTemplateAnnotationFromYAMLComment added in v0.48.0 

func NewTemplateAnnotationFromYAMLComment(comment *yamlmeta.Comment, nodePos *filepos.Position, opts template.MetaOpts) (template.Annotation, error)

NewTemplateAnnotationFromYAMLComment parses "comment" into template.Annotation. nodePos is the position of the node to which "comment" is attached.

When a comment contains a shorthand annotation (i.e. `#@ `):

  • if the comment is above its node, it's a template.AnnotationCode annotation: it's _merely_ contributing raw Starlark code.
  • if the comment is on the same line as its node, it's a template.AnnotationValue annotation: it's meant to set the value of the annotated node.

Types

type CommentAndAnnotation added in v0.48.0 

type CommentAndAnnotation struct {
	Comment    *yamlmeta.Comment
	Annotation *template.Annotation
}

type EvaluationCtx 

type EvaluationCtx struct {
	// contains filtered or unexported fields
}

func (EvaluationCtx) PrepareNode 

func (e EvaluationCtx) PrepareNode(parentNode template.EvaluationNode, val template.EvaluationNode) error

PrepareNode pre-processes the template.EvaluationNode so that the resulting AST fully reflects having been evaluated.

func (EvaluationCtx) Replace 

func (e EvaluationCtx) Replace(
	parentNodes []template.EvaluationNode, val interface{}) error

func (EvaluationCtx) SetMapItemKey added in v0.17.0 

func (e EvaluationCtx) SetMapItemKey(node template.EvaluationNode, val interface{}) error

func (EvaluationCtx) ShouldWrapRootValue 

func (e EvaluationCtx) ShouldWrapRootValue(nodeVal interface{}) bool

func (EvaluationCtx) WrapRootValue 

func (e EvaluationCtx) WrapRootValue(val interface{}) interface{}

type MapItemOverride 

type MapItemOverride struct {
	// contains filtered or unexported fields
}

func (MapItemOverride) Apply 

func (d MapItemOverride) Apply(
	typedMap *yamlmeta.Map, newItem *yamlmeta.MapItem, strict bool) error

type Metas 

type Metas struct {
	Block       []*yamlmeta.Comment // meant to execute some code
	Values      []*yamlmeta.Comment // meant to return interpolated value
	Annotations []CommentAndAnnotation
	// contains filtered or unexported fields
}

Metas are the collection of ytt YAML templating values parsed from the comments attached to a yamlmeta.Node

func (Metas) NeedsEnd 

func (m Metas) NeedsEnd() bool
