var ErrUnknownSDKLang = errors.New("unknown sdk language")

Functions

func GetSchema

func GetSchema() *introspection.Schema

func Introspect

func Introspect(ctx context.Context, dag *dagger.Client) (*introspection.Schema, error)

Introspect gets the Dagger Schema

func Overlay

func Overlay(ctx context.Context, logsW io.Writer, overlay fs.FS, outputDir string) (rerr error)

func SetSchema

func SetSchema(schema *introspection.Schema)

func SetSchemaParents

func SetSchemaParents(schema *introspection.Schema)

SetSchemaParents sets all the parents for the fields.

Types

type CommonFunctions

type CommonFunctions struct {
	// contains filtered or unexported fields
}

CommonFunctions formatting function with global shared template functions.

func NewCommonFunctions

func NewCommonFunctions(formatTypeFuncs FormatTypeFuncs) *CommonFunctions

func (*CommonFunctions) ConvertID

func (c *CommonFunctions) ConvertID(f introspection.Field) bool

ConvertID returns true if the field returns an ID that should be converted into an object.

func (*CommonFunctions) FormatInputType

func (c *CommonFunctions) FormatInputType(r *introspection.TypeRef, scopes ...string) (string, error)

FormatInputType formats a GraphQL type into the SDK language input

Example: `String` -> `string`

func (*CommonFunctions) FormatOutputType

func (c *CommonFunctions) FormatOutputType(r *introspection.TypeRef, scopes ...string) (string, error)

FormatOutputType formats a GraphQL type into the SDK language output

Example: `String` -> `string`

func (*CommonFunctions) FormatReturnType

func (c *CommonFunctions) FormatReturnType(f introspection.Field, scopes ...string) (string, error)

FormatReturnType formats a GraphQL type into the SDK language output, unless it's an ID that will be converted which needs to be formatted as an input (for chaining).

func (*CommonFunctions) GetArrayField

func (c *CommonFunctions) GetArrayField(f *introspection.Field) ([]*introspection.Field, error)

func (*CommonFunctions) InnerType

func (c *CommonFunctions) InnerType(t *introspection.TypeRef) *introspection.TypeRef

func (*CommonFunctions) IsIDableObject

func (c *CommonFunctions) IsIDableObject(t *introspection.TypeRef) (bool, error)

func (*CommonFunctions) IsListOfObject

func (c *CommonFunctions) IsListOfObject(t *introspection.TypeRef) bool

func (*CommonFunctions) IsSelfChainable

func (c *CommonFunctions) IsSelfChainable(t introspection.Type) bool

IsSelfChainable returns true if an object type has any fields that return that same type.

func (*CommonFunctions) ObjectName

func (c *CommonFunctions) ObjectName(t *introspection.TypeRef) (string, error)

func (*CommonFunctions) ToLowerCase

func (c *CommonFunctions) ToLowerCase(s string) string

func (*CommonFunctions) ToUpperCase

func (c *CommonFunctions) ToUpperCase(s string) string

type Config

type Config struct {
	// Language supported by this codegen infra.
	Lang SDKLang

	// Destination directory for generated code.
	OutputDir string

	// Name of the module to generate code for
	ModuleName        string
	ModuleContextPath string

	// Optional pre-computed introspection json string
	IntrospectionJSON string
}

type FormatTypeFuncs

type FormatTypeFuncs interface {
	WithScope(scope string) FormatTypeFuncs

	FormatKindList(representation string) string
	FormatKindScalarString(representation string) string
	FormatKindScalarInt(representation string) string
	FormatKindScalarFloat(representation string) string
	FormatKindScalarBoolean(representation string) string
	FormatKindScalarDefault(representation string, refName string, input bool) string
	FormatKindObject(representation string, refName string, input bool) string
	FormatKindInputObject(representation string, refName string, input bool) string
	FormatKindEnum(representation string, refName string) string
}

FormatTypeFuncs is an interface to format any GraphQL type. Each generator has to implement this interface.

type GeneratedState

type GeneratedState struct {
	// Overlay is the overlay filesystem that contains generated code to write
	// over the output directory.
	Overlay fs.FS

	// PostCommands are commands that need to be run after the codegen has
	// finished. This is used for example to run `go mod tidy` after generating
	// Go code.
	PostCommands []*exec.Cmd

	// NeedSync indicates that the code needs to be generated again. This can
	// happen if the codegen spat out templates that depend on generated types.
	// In that case the codegen needs to be run again with both the templates and
	// the initially generated types available.
	NeedRegenerate bool
}

type Generator

type Generator interface {
	// Generate runs codegen and returns a map of default filename to content for that file.
	Generate(ctx context.Context, schema *introspection.Schema) (*GeneratedState, error)
}

type SDKLang

type SDKLang string

const (
	SDKLangGo         SDKLang = "go"
	SDKLangTypeScript SDKLang = "typescript"
)
