Latest commit

* Update to support unit32

After this update artonge/go-gtfs#22, the sequence always returned 0 because this library didn't support uint32. This should fix the issue. Tested with the go-gtfs library with this change.

* updated to fallthrough and added uint64

* Added unint and int32 as well

PRs Welcome

The project is in maintenance mode.

It is kept compatible with changes in the Go ecosystem but no new features will be developed. PR could be accepted.

Install

go get github.com/artonge/go-csv-tag/v2

Example

Load

The csv file:

name, ID, number
name1, 1, 1.2
name2, 2, 2.3
name3, 3, 3.4

Your Go code:

type Demo struct {                                // A structure with tags
	Name string  `csv:"name"`
	ID   int     `csv:"ID"`
	Num  float64 `csv:"number"`
}

tab := []Demo{}                                   // Create the slice where to put the content
err  := csvtag.LoadFromPath(
	"file.csv",                                   // Path of the csv file
	&tab,                                         // A pointer to the create slice
	csvtag.CsvOptions{                            // Load your csv with optional options
		Separator: ';',                           // changes the values separator, default to ','
		Header: []string{"name", "ID", "number"}, // specify custom headers
})

You can also load the data from an io.Reader with:

csvtag.LoadFromReader(youReader, &tab)

Or from a string with:

csvtag.LoadFromString(yourString, &tab)

Dump

Your Go code:

type Demo struct {                         // A structure with tags
	Name string  `csv:"name"`
	ID   int     `csv:"ID"`
	Num  float64 `csv:"number"`
}

tab := []Demo{                             // Create the slice where to put the content
	Demo{
		Name: "some name",
		ID: 1,
		Num: 42.5,
	},
}

err := csvtag.DumpToFile(tab, "csv_file_name.csv")

You can also dump the data into an io.Writer with:

err := csvtag.DumpToWriter(tab, yourIOWriter)

Or dump to a string with:

str, err := csvtag.DumpToString(tab)

The csv file written:

name,ID,number
some name,1,42.5
