Functions

func DefinitionsYAML

func DefinitionsYAML() string

DefinitionsYAML is the embedded YAML file containing the definitions.yaml for the VSS schema.

func Validate

func Validate(d *DefinitionInfo) error

Validate checks if the definition is valid.

func VssRel42DIMO

func VssRel42DIMO() string

VssRel42DIMO is the embedded CSV file containing the VSS schema for DIMO.

Types

type ConversionInfo

type ConversionInfo struct {
	OriginalName string `json:"originalName" yaml:"originalName"`
	OriginalType string `json:"originalType" yaml:"originalType"`
	IsArray      bool   `json:"isArray"      yaml:"isArray"`
}

ConversionInfo contains the conversion information for a field.

type DefinitionInfo

type DefinitionInfo struct {
	VspecName          string            `json:"vspecName"          yaml:"vspecName"`
	GoType             string            `json:"goType"             yaml:"goType"`
	Conversions        []*ConversionInfo `json:"conversions"        yaml:"conversions"`
	RequiredPrivileges []string          `json:"requiredPrivileges" yaml:"requiredPrivileges"`
}

DefinitionInfo contains the definition information for a field.

type Definitions

type Definitions struct {
	FromName map[string]*DefinitionInfo
	Signals  []*SignalInfo
}

Definitions is a map of definitions from clickhouse Name to definition info.

func LoadDefinitionFile

func LoadDefinitionFile(r io.Reader) (*Definitions, error)

LoadDefinitionFile loads the definitions from a definitions.yaml file.

func (*Definitions) DefinedSignal

func (m *Definitions) DefinedSignal(signal []*SignalInfo) []*SignalInfo

DefinedSignal returns a new slice of signals with the definition information applied. excluding signals that are not in the definition file.

type ErrInvalid

type ErrInvalid struct {
	Property string
	Name     string
	Reason   string
}

ErrInvalid is an error for invalid definitions.

func (ErrInvalid) Error

func (e ErrInvalid) Error() string

type SignalInfo

type SignalInfo struct {
	// From spec CSV
	Name       string
	Type       string
	DataType   string
	Unit       string
	Min        string
	Max        string
	Desc       string
	Deprecated bool

	// Derived
	IsArray     bool
	GOName      string
	JSONName    string
	BaseGoType  string
	BaseGQLType string
	Conversions []*ConversionInfo
	Privileges  []string
}

SignalInfo holds information about a signal that is accessed during template execution. This information comes from the combinations of the spec and definition files. The Types defined by this stuct are used to determine what strings to use in the template file.

func LoadSignalsCSV

func LoadSignalsCSV(r io.Reader) ([]*SignalInfo, error)

LoadSignalsCSV loads the signals from a vss CSV file.

func NewSignalInfo

func NewSignalInfo(record []string) *SignalInfo

NewSignalInfo creates a new SignalInfo from a record from the CSV file.

func (*SignalInfo) GOType

func (s *SignalInfo) GOType() string

GOType returns the golang type of the signal.

func (*SignalInfo) GQLType

func (s *SignalInfo) GQLType() string

GQLType returns the graphql type of the signal.

func (*SignalInfo) MergeWithDefinition

func (s *SignalInfo) MergeWithDefinition(definition *DefinitionInfo)

MergeWithDefinition merges the signal with the definition information.

type TemplateData

type TemplateData struct {
	PackageName string
	ModelName   string
	Signals     []*SignalInfo
}

TemplateData contains the data to be used during template execution.

func GetDefinedSignals

func GetDefinedSignals(specReader, definitionReader io.Reader) (*TemplateData, error)

GetDefinedSignals reads the signals and definitions files and merges them.
