csvlib

A simple CSV parsing library for Go.

How to use

One can define a parser:

var parser = &csvlib.RowParser{
	[]csvlib.Parser{
		csvlib.Int64Parser{"ID"},
		csvlib.Int32Parser{Name: "Number"}, // CKK
		csvlib.TimeParser{"Timestamp", "2006-01-02 15:04:05"},
		csvlib.StringParser{"Name"},
	},
}

type Data struct {
	ID int64
	Number int32
	Time time.Time
	Name string
}

// and use it to parse row:
reader := csv.NewReader(r)
record, err := reader.Read()          // reads one line
values, err := parser.Parse(record)   // converts values
dat := Data{
	values[0].Int64(),
	values[1].Int32(),
	values[2].Time(),
	values[3].String(),
}

The most common usecase is when a you want to give the user the possibility to choose columns. It can be configured though a config file or UI.

Also it's pretty easy to create your own type of data (e.g. Decimal with fixed precision), you must implement Parser interface.

If you want to parse directly to structure, you may be interested in: github.com/gocarina/gocsv which is using a reflection mechanism and custom structure tag.
