Functions

func Save

func Save(w io.Writer, proj *Project) error

Save saves a Project configuration to YAML.

Types

type API

type API struct {
	Name      string         `json:"-"`
	Resources []*ResourceSet `json:"resources"`
	Overlays  []*Overlay     `json:"overlays"`
	Output    *Output        `json:"output"`
}

An API defines how and where to build versioned OpenAPI documents from a source collection of individual resource specifications and additional overlay content to merge.

type APIs

type APIs map[string]*API

APIs defines a named map of API instances.

type Generator

type Generator struct {
	Name      string         `json:"-"`
	Scope     GeneratorScope `json:"scope"`
	Filename  string         `json:"filename,omitempty"`
	Template  string         `json:"template"`
	Files     string         `json:"files,omitempty"`
	Functions string         `json:"functions,omitempty"`
}

Generator describes how files are generated for a resource.

type GeneratorScope

type GeneratorScope string

GeneratorScope determines the template context when running the generator. Different scopes allow templates to operate over a single resource version, or all versions in a resource, for example.

type Generators

type Generators map[string]*Generator

Generators defines a named map of Generator instances.

func LoadGenerators

func LoadGenerators(r io.Reader) (Generators, error)

LoadGenerators loads Generators from their YAML representation.

type Linter

type Linter struct {
	Name        string          `json:"-"`
	Description string          `json:"description,omitempty"`
	Spectral    *SpectralLinter `json:"spectral"`
	SweaterComb *OpticCILinter  `json:"sweater-comb"`
	OpticCI     *OpticCILinter  `json:"optic-ci"`
}

Linter describes a set of standards and rules that an API should satisfy.

type Linters

type Linters map[string]*Linter

Linters defines a named map of Linter instances.

type OpticCILinter

type OpticCILinter struct {
	// Image identifies the Optic CI docker image to use for linting.
	Image string

	// Script identifies the path to the Optic CI script to use for linting.
	// Mutually exclusive with Image; if Script is specified Docker will not be
	// used.
	Script string

	// Original is where to source the original version of an OpenAPI spec file
	// when comparing. If empty, all changes are assumed to be new additions.
	Original string `json:"original,omitempty"`

	// Proposed is where to source the proposed changed version of an OpenAPI
	// spec file when comparing. If empty, this is assumed to be the
	// local working copy.
	Proposed string `json:"proposed,omitempty"`

	// Debug turns on debug logging.
	Debug bool `json:"debug,omitempty"`

	// CIContext specifies the location of an optional CI context JSON file to
	// use when performing an optic-ci compare or bulk-compare. If this file is
	// present when vervet lints, it will be passed to optic using the
	// --ci-context option.
	//
	// See https://www.npmjs.com/package/@useoptic/api-checks#expected-contexts
	// for more information.
	CIContext string `json:"ciContext"`

	// UploadResults indicates that the comparison results from optic-ci should
	// be uploaded to Optic Cloud. This only happens if the file specified by
	// CIContext exists.
	UploadResults bool `json:"uploadResults"`

	// Exceptions are files that are excluded from CI checks. This is an escape
	// hatch of last resort, if a file needs to land and can't pass CI yet.
	// They are specified as a mapping from project relative path to sha256
	// sums of that spec file that is exempt. This makes the exception very
	// narrow -- only a specific version of a specific file is skipped, after
	// outside review and approval.
	Exceptions map[string][]string

	// ExtraArgs may be used to pass extra arguments to `optic-ci`.
	ExtraArgs []string `json:"extraArgs"`
}

OpticCILinter identifies an Optic CI Linter, which is distributed as a self-contained docker image.

type Output

type Output struct {
	Path   string `json:"path"`
	Linter string `json:"linter"`
}

Output defines where the aggregate versioned OpenAPI specs should be created during compilation.

type Overlay

type Overlay struct {
	Include string `json:"include"`
	Inline  string `json:"inline"`
}

An Overlay defines additional OpenAPI documents to merge into the aggregate OpenAPI spec when compiling an API. These might include special endpoints that should be included in the aggregate API but are not versioned, or top-level descriptions of the API itself.

type Project

type Project struct {
	Version    string     `json:"version"`
	Linters    Linters    `json:"linters,omitempty"`
	Generators Generators `json:"generators,omitempty"`
	APIs       APIs       `json:"apis"`
}

Project defines collection of APIs and the standards they adhere to.

func Load

func Load(r io.Reader) (*Project, error)

Load loads a Project configuration from its YAML representation.

func (*Project) APINames

func (p *Project) APINames() []string

APINames returns the API names in deterministic ascending order.

type ResourceSet

type ResourceSet struct {
	Description     string             `json:"description"`
	Linter          string             `json:"linter"`
	LinterOverrides map[string]Linters `json:"linter-overrides"`
	Path            string             `json:"path"`
	Excludes        []string           `json:"excludes"`
}

A ResourceSet defines a set of versioned resources that adhere to the same standards.

Versioned resources are expressed as individual OpenAPI documents in a directory structure:

+-resource

|
+-2021-08-01
| |
| +-spec.yaml
| +-<implementation code, etc. can go here>
|
+-2021-08-15
| |
| +-spec.yaml
| +-<implementation code, etc. can go here>
...

Each YYYY-mm-dd directory under a resource is a version. The spec.yaml in each version is a complete OpenAPI document describing the resource at that version.

type SpectralLinter

type SpectralLinter struct {

	// Rules are a list of Spectral ruleset file locations
	Rules []string `json:"rules"`

	// ExtraArgs may be used to pass extra arguments to `spectral lint`. If not
	// specified, the default arguments `--format text` are used when running
	// spectral. The `-r` flag must not be specified here, as this argument is
	// automatically added from the Rules setting above.
	//
	// See https://meta.stoplight.io/docs/spectral/ZG9jOjI1MTg1-spectral-cli
	// for the options supported.
	ExtraArgs []string `json:"extraArgs"`
}

SpectralLinter identifies a Linter as a collection of Spectral rulesets.
