Embed CSV data as a Golang package.
go get github.com/mmcloughlin/databundler
We'll use the Seven Summits as our example. The CSV we are going to embed into a package looks like
Mount Everest,8848,8848,Asia,Himalaya,Nepal/China,1953
Aconcagua,6961,6961,South America,Andes,Argentina,1897
Denali,6194,6144,North America,Alaska Range,United States,1913
Kilimanjaro,5895,5885,Africa,,Tanzania,1889
Mount Elbrus,5642,4741,Europe,Caucasus Mountains,Russia,1874
Mount Vinson,4892,4892,Antarctica,Sentinel Range,,1966
Puncak Jaya,4884,4884,Australasia,Sudirman Range,Indonesia,1962

type: intBuild the Go source with the following commands.
databundler -pkg sevensummits -data sevensummits.csv -schema schema.yaml -output sevensummits.go
gofmt -w sevensummits.goResulting in the following code.
// Generated code. DO NOT EDIT.
package sevensummits
// Peak represents a mountain.
type Peak struct {
Name string
// Elevation in meters.
Elevation int
Continent string
// Name of mountain range.
