// Flatten an analyzed spec and produce a self-contained spec bundle.
|
|
//
|
|
// There is a minimal and a full flattening mode.
|
|
//
|
|
// Minimally flattening a spec means:
|
|
// - Expanding parameters, responses, path items, parameter items and header items (references to schemas are left
|
|
// unscathed)
|
|
// - Importing external (http, file) references so they become internal to the document
|
|
// - Moving every JSON pointer to a $ref to a named definition (i.e. the reworked spec does not contain pointers
|
|
// like "$ref": "#/definitions/myObject/allOfs/1")
|
|
//
|
|
// A minimally flattened spec thus guarantees the following properties:
|
|
// - all $refs point to a local definition (i.e. '#/definitions/...')
|
|
// - definitions are unique
|
|
//
|
|
// NOTE: arbitrary JSON pointers (other than $refs to top level definitions) are rewritten as definitions if they
|
|
// represent a complex schema or express commonality in the spec.
|
|
// Otherwise, they are simply expanded.
|
|
// Self-referencing JSON pointers cannot resolve to a type and trigger an error.
|
|
//
|
|
// Minimal flattening is necessary and sufficient for codegen rendering using go-swagger.
|
|
//
|
|
// Fully flattening a spec means:
|
|
// - Moving every complex inline schema to be a definition with an auto-generated name in a depth-first fashion.
|
|
//
|
|
// By complex, we mean every JSON object with some properties.
|
|
// Arrays, when they do not define a tuple,
|
|
// or empty objects with or without additionalProperties, are not considered complex and remain inline.
|
|
//
|
|
// NOTE: rewritten schemas get a vendor extension x-go-gen-location so we know from which part of the spec definitions
|
|
// have been created.
|
|
//
|
|
// Available flattening options:
|
|
// - Minimal: stops flattening after minimal $ref processing, leaving schema constructs untouched
|
|
// - Expand: expand all $ref's in the document (inoperant if Minimal set to true)
|
|
// - Verbose: croaks about name conflicts detected
|
|
// - RemoveUnused: removes unused parameters, responses and definitions after expansion/flattening
|
|
//
|
|
// NOTE: expansion removes all $ref save circular $ref, which remain in place
|
|
//
|
|
// TODO: additional options
|
|
// - ProgagateNameExtensions: ensure that created entries properly follow naming rules when their parent have set a
|
|
// x-go-name extension
|
|
// - LiftAllOfs:
|
|
// - limit the flattening of allOf members when simple objects
|
|
// - merge allOf with validation only
|
|
// - merge allOf with extensions only
|
|
