Functions

func CSV

func CSV(args ...string) [][]string

CSV - Unmarshal CSV parameters:

delim - (optional) the (single-character!) field delimiter, defaults to ","
   in - the CSV-format string to parse

returns:

an array of rows, which are arrays of cells (strings)

func CSVByColumn

func CSVByColumn(args ...string) (cols map[string][]string)

CSVByColumn - Unmarshal CSV in a Columnar form parameters:

delim - (optional) the (single-character!) field delimiter, defaults to ","
  hdr - (optional) comma-separated list of column names,
        set to "" to get auto-named columns (A-Z), omit
        to use the first line
   in - the CSV-format string to parse

returns:

a map of columns, indexed by the header name. values are arrays of strings

func CSVByRow

func CSVByRow(args ...string) (rows []map[string]string)

CSVByRow - Unmarshal CSV in a row-oriented form parameters:

delim - (optional) the (single-character!) field delimiter, defaults to ","

        set to "" to get auto-named columns (A-Z), omit
        to use the first line
   in - the CSV-format string to parse

returns:

an array of rows, indexed by the header name
