Functions

func Build 

func Build(phrase string) *sqlx.Builder

Build instantiates a new builder and writes the given phrase to it.

func FormatType added in v0.2.0 

func FormatType(t schema.Type) (string, error)

FormatType converts schema type to its column form in the database. An error is returned if the type cannot be recognized.

func MarshalSpec 

func MarshalSpec(v interface{}, marshaler schemaspec.Marshaler) ([]byte, error)

MarshalSpec marshals v into an Atlas DDL document using a schemaspec.Marshaler.

func ParseType added in v0.3.1 

func ParseType(typ string) (schema.Type, error)

ParseType returns the schema.Type value represented by the given raw type. The raw value is expected to follow the format in PostgreSQL information schema or as an input for the CREATE TABLE statement.

func Realm added in v0.3.1 

func Realm(schemas []*sqlspec.Schema, tables []*sqlspec.Table, enums []*Enum) (*schema.Realm, error)

Realm converts the schemas and tables of the doc into a schema.Realm.

func Schema added in v0.3.1 

func Schema(spec *sqlspec.Schema, tables []*sqlspec.Table, enums []*Enum) (*schema.Schema, error)

Schema converts a sqlspec.Schema with its relevant []sqlspec.Tables and []Enum into a schema.Schema.

func UnmarshalSpec 

func UnmarshalSpec(data []byte, unmarshaler schemaspec.Unmarshaler, v interface{}) error

UnmarshalSpec unmarshals an Atlas DDL document using an unmarshaler into v.
