type Expr 

type Expr interface {
	Node

	Syntax() syntax.Node
	// contains filtered or unexported methods

Expr represents a Pulumi YAML expression. Expressions may be literals, interpolated strings, symbols, or builtin functions.

func ParseExpr 

func ParseExpr(node syntax.Node) (Expr, syntax.Diagnostics)

ParseExpr parses an expression from the given syntax tree.

The syntax tree is parsed using the following rules:

  • *syntax.{Null,Boolean,Number}Node is parsed as a *{Null,Boolean,Number}Expr.
  • *syntax.ArrayNode is parsed as a *ArrayExpr.
  • *syntax.StringNode is parsed as an *InterpolateExpr, a *SymbolExpr, or a *StringExpr. The node's literal is first parsed as an interpolated string. If the result contains a single property access with no surrounding text, (i.e. the string is of the form "${resource.property}", it is treated as a symbol. If the result contains no property accesses, it is treated as a string literal. Otherwise, it it treated as an interpolated string.
  • *syntax.ObjectNode is parses as either an *ObjectExpr or a BuiltinExpr. If the object contains a single key and that key names a builtin function ("fn::invoke", "fn::join", "fn::select", "fn::*Asset", "fn::*Archive", or "fn::stackReference"), then the object is parsed as the corresponding BuiltinExpr. Otherwise, the object is parsed as a *syntax.ObjectNode.

type InterpolateExpr 

type InterpolateExpr struct {

Interpolated strings are represented syntactically as strings of the form "some text with ${property.accesses}". During evaluation, each access replaced with its evaluated value coerced to a string.

In order to allow convenient access to object properties without string coercion, a string of the form "${property.access}" is parsed as a symbol rather than an interpolated string.
