Types

type Catalog 

type Catalog struct {
	Name        string
	Environment string
	Version     int64
	// contains filtered or unexported fields
}

Catalog is a compiled catalog for one node.

func New 

func New(name string) *Catalog

New creates an empty catalog for the named node.

func (*Catalog) Add 

func (c *Catalog) Add(r *Resource) error

Add inserts r, returning an error if a resource with the same reference is already present (Puppet forbids duplicate resource declarations).

func (*Catalog) AddEdge 

func (c *Catalog) AddEdge(source, target string)

AddEdge records a directed edge source -> target, de-duplicating.

func (*Catalog) Edges 

func (c *Catalog) Edges() []Edge

Edges returns the edges in insertion order.

func (*Catalog) Get 

func (c *Catalog) Get(ref string) (*Resource, bool)

Get returns the resource for ref (`Type[Title]`) and whether it exists.

func (*Catalog) JSON 

func (c *Catalog) JSON() string

JSON renders the catalog in the Puppet catalog JSON shape. It is written by hand (no reflection) so the field order is stable and deterministic.

func (*Catalog) Resources 

func (c *Catalog) Resources() []*Resource

Resources returns the resources in declaration order.

type DuplicateError 

type DuplicateError struct{ Ref string }

DuplicateError reports a duplicate resource declaration.

func (*DuplicateError) Error 

func (e *DuplicateError) Error() string

Error implements error.

type Edge 

type Edge struct {
	Source string
	Target string
}

Edge is a directed relationship between two resource references.

type Resource 

type Resource struct {
	Type       string
	Title      string
	Parameters map[string]any
	Tags       []string
	Exported   bool
	Virtual    bool
}

Resource is one catalog resource: a typed, titled bag of parameters plus its tags and virtual/exported flags.

func (*Resource) Ref 

func (r *Resource) Ref() string

Ref returns the canonical Puppet reference `Type[Title]`.
