Types

type Reader

type Reader struct {
	Reader  *csv.Reader
	Columns []string
}

A Reader reads records from a CSV-encoded file.

func NewReader

func NewReader(r io.Reader) *Reader

NewReader returns a new Reader that reads from r.

func (*Reader) Read

func (r *Reader) Read() (record map[string]string, err error)

Read wraps csv.Reader.Read, creating a map of column name to field value. If the line has fewer columns than Reader.Columns, the map will not contain keys for these columns; thus we can distinguish between missing columns and columns with empty values. If the line has more columns than Reader.Columns, Reader.Read() ignores them.

func (*Reader) ReadAll

func (r *Reader) ReadAll() (records []map[string]string, err error)

ReadAll reads all the remaining records from r. Each record is a map of column name to field value.

func (*Reader) ReadHeader

func (r *Reader) ReadHeader() (columns []string, err error)

ReadHeader simply wraps csv.Reader.Read().
