Types

type ConstGenerator

type ConstGenerator struct {
	Values []string `yaml:"values"`
}

ConstGenerator provides additional context to a const column.

func (ConstGenerator) Generate

func (g ConstGenerator) Generate(t model.Table, files map[string]model.CSVFile) error

Generate values for a column based on a series of provided values.

type EachGenerator

type EachGenerator struct {
	Table  string `yaml:"table"`
	Column string `yaml:"column"`
}

EachGenerator provides additional context to an each or ref column.

func (EachGenerator) Generate

func (g EachGenerator) Generate(t model.Table, files map[string]model.CSVFile) error

Generate looks for any each type columns for a table, and returns their Cartesian product back into the given files map.

type Formatter

type Formatter interface {
	Format(string) string
}

Formatter determines the behaviour for anything that can take a format string and return another.

type FormatterProcessor

type FormatterProcessor interface {
	GetFormat() string
}

FormatterProcessor can be called to get the Format string out of a struct that implements this interface.

type GenGenerator

type GenGenerator struct {
	Value          string `yaml:"value"`
	Pattern        string `yaml:"pattern"`
	NullPercentage int    `yaml:"null_percentage"`
	Format         string `yaml:"format"`
	// contains filtered or unexported fields
}

GenGenerator provides additional context to a gen column.
