Functions

func AddTemplate 

func AddTemplate(scope Scope, node Node, tag *tokens.Tag) error

doesnt change the node

func AddVar 

func AddVar(scope Scope, node Node, tag *tokens.Tag) error

doesnt change the node

func AppendToBlock 

func AppendToBlock(scope Scope, node *TemplateNode, tag *tokens.Tag) error

func AssertValidVar

func BuildFile 

func BuildFile(cache *FileCache, path string, isRoot bool, parameters *tokens.Parens) (*FileScope, *RootNode, error)

also used by NewRoot abs path, so we can use this to cache the import results incoming parameters should be evaluated

func BuildSVG 

func BuildSVG(scope Scope, node Node, tag *tokens.Tag) error

func BuildTag 

func BuildTag(scope Scope, node Node, tag *tokens.Tag) error
