func RewriteApplies 

func RewriteApplies(n BoundNode) (BoundNode, error)

RewriteApplies transforms all bound expression trees in the given BoundNode that reference output-typed properties into appropriate calls to the __apply and __applyArg intrinsic. Given an expression tree, the rewrite proceeds as follows: - let the list of outputs be an empty list - for each node in post-order:

  • if the node is the root of the expression tree:
  • if the node is a variable access:
  • if the access has an output-typed element on its path, replace the variable access with a call to the __applyArg intrinsic and append the access to the list of outputs.
  • otherwise, the access does not need to be transformed; return it as-is.
  • if the list of outputs is empty, the root does not need to be transformed; return it as-is.
  • otherwise, replace the root with a call to the __apply intrinstic. The first n arguments to this call are the elementss of the list of outputs. The final argument is the original root node.
  • otherwise, if the root is an output-typed variable access, replace the variable access with a call to the __applyArg instrinsic and append the access to the list of outputs.

As an example, this transforms the following expression: 

(output string
    "#!/bin/bash -xe\n\nCA_CERTIFICATE_DIRECTORY=/etc/kubernetes/pki\necho \""
    (aws_eks_cluster.demo.certificate_authority.0.data output<unknown> *config.ResourceVariable)
    "\" | base64 -d >  $CA_CERTIFICATE_FILE_PATH\nsed -i s,MASTER_ENDPOINT,"
    (aws_eks_cluster.demo.endpoint output<string> *config.ResourceVariable)
    ",g /var/lib/kubelet/kubeconfig\nsed -i s,CLUSTER_NAME,"
    (var.cluster-name string *config.UserVariable)
    ",g /var/lib/kubelet/kubeconfig\nsed -i s,REGION,"
    (data.aws_region.current.name output<string> *config.ResourceVariable)
    ",g /etc/systemd/system/kubelet.servicesed -i s,MASTER_ENDPOINT,"
    (aws_eks_cluster.demo.endpoint output<string> *config.ResourceVariable)
    ",g /etc/systemd/system/kubelet.service"
)

into this expression: 

(call output<unknown> __apply
    (aws_eks_cluster.demo.certificate_authority.0.data output<unknown> *config.ResourceVariable)
    (aws_eks_cluster.demo.endpoint output<string> *config.ResourceVariable)
    (data.aws_region.current.name output<string> *config.ResourceVariable)
    (aws_eks_cluster.demo.endpoint output<string> *config.ResourceVariable)
    (output string
        "#!/bin/bash -xe\n\nCA_CERTIFICATE_DIRECTORY=/etc/kubernetes/pki\necho \""
        (call unknown __applyArg
            0
        )
        "\" | base64 -d >  $CA_CERTIFICATE_FILE_PATH\nsed -i s,MASTER_ENDPOINT,"
        (call string __applyArg
            1
        )
        ",g /var/lib/kubelet/kubeconfig\nsed -i s,CLUSTER_NAME,"
        (var.cluster-name string *config.UserVariable)
        ",g /var/lib/kubelet/kubeconfig\nsed -i s,REGION,"
        (call string __applyArg
            2
        )
        ",g /etc/systemd/system/kubelet.servicesed -i s,MASTER_ENDPOINT,"
        (call string __applyArg
            3
        )
        ",g /etc/systemd/system/kubelet.service"

A ResourceNode is the analyzed form of a resource or data source instatiation in a Terraform configuration. In keeping with Terraform's internal terminology, these concepts will be collectively referred to as resources: when it is necessary to differentiate between the two, the former are referred to as "managed resources" and the latter as "data resources".

func (*ResourceNode) Dependencies 

func (r *ResourceNode) Dependencies() []Node

Depdendencies returns the list of nodes the resource depends on.

func (*ResourceNode) GetLocation 

func (r *ResourceNode) GetLocation() token.Pos

func (*ResourceNode) ID 

func (r *ResourceNode) ID() string

func (*ResourceNode) Schemas 

func (r *ResourceNode) Schemas() Schemas

Schemas returns the Terraform and Pulumi schemas for this resource. These schemas can are principally used to calculate the types and names of a resource's properties during binding and code generation.

func (*ResourceNode) Tok 

func (r *ResourceNode) Tok() (string, bool)

Tok returns the Pulumi token for this resource. These tokens are of the form "provider:module/func:member".

type Schemas 

type Schemas struct {
	TF     shim.Schema
	TFRes  shim.Resource
	Pulumi *tfbridge.SchemaInfo
}

Schemas bundles a property's Terraform and Pulumi schema information into a single type. This information is then used to determine type and name information for the property. If the Terraform property is of a composite type--a map, list, or set--the property's schemas may also be used to access child schemas.

func (Schemas) ElemSchemas 

func (s Schemas) ElemSchemas() Schemas

ElemSchemas returns the element Schemas for a list property.

func (Schemas) ModelType 

func (s Schemas) ModelType() model.Type

ModelType returns the appropriate model type for the property associated with these Schemas.

func (Schemas) PropertySchemas 

func (s Schemas) PropertySchemas(key string) Schemas

PropertySchemas returns the Schemas for the child property with the given name. If the name is an integer, this function returns the value of a call to ElemSchemas.

func (Schemas) Type 

func (s Schemas) Type() Type

Type returns the appropriate bound type for the property associated with these Schemas.

type Type 

type Type uint32

Type represents the type of a single node in a bound property tree. Types are fairly simplistic: in addition to the primitive types--bool, string, number, map, and unknown--there are the composite types list and output. A type that is both a list and an output is considered to be an output of a list. Outputs have the semantic that their values may not be known promptly; in particular, the target language may need to introduce special elements (e.g. `apply`) to access the concrete value of an output. 

const (
	// TypeInvalid is self-explanatory.
	TypeInvalid Type = 0
	// TypeBool represents the universe of boolean values.
	TypeBool Type = 1
	// TypeString represents the universe of string values.
	TypeString Type = 1 << 1
	// TypeNumber represents the universe of real number values.
	TypeNumber Type = 1 << 2
	// TypeMap represents the universe of string -> unknown values.
	TypeMap Type = 1 << 3
	// TypeUnknown represnets the universe of unknown values. These values may have any type at runtime, and dynamic
	// conversions may be necessary when assigning these values to differently-typed destinations.
	TypeUnknown Type = 1 << 4

	// TypeList represents the universe of list values. A list's element type must be a primitive type.
	TypeList Type = 1 << 5
	// TypeOutput represents the universe of output value.
	TypeOutput Type = 1 << 6
)

func (Type) ElementType 

func (t Type) ElementType() Type

ElementType returns the element type of this value.

func (Type) IsList 

func (t Type) IsList() bool

IsList returns true if this value represents a list type.

func (Type) IsOutput 

func (t Type) IsOutput() bool

IsOutput returns true if this value represents an output type.

func (Type) ListOf 

func (t Type) ListOf() Type

ListOf returns this a list type with this value as its element type.

func (Type) OutputOf 

func (t Type) OutputOf() Type

ListOf returns this an output type with this value as its element type.

func (Type) String 

func (t Type) String() string

String returns the string representation of this type.

type VariableNode 

type VariableNode struct {
	// Config is the variable's raw Terraform configuration.
	Config *config.Variable
	// Location is the location of this node's definition in the original Terraform configuration.
	Location token.Pos
	// Comments is the set of comments associated with this node, if any.
	Comments *Comments
	// Name is the name of this variable.
	Name string
	// DefaultValue is the bound form of the variable's default value (if any).
	DefaultValue BoundNode
}

A VariableNode is the analyzed form of a Terraform variable. A VariableNode's list of dependencies is always empty.

func (*VariableNode) Dependencies 

func (v *VariableNode) Dependencies() []Node

Depdendencies returns the list of nodes the variable depends on. This list is always empty.

func (*VariableNode) GetLocation 

func (v *VariableNode) GetLocation() token.Pos

func (*VariableNode) ID 

func (v *VariableNode) ID() string
