Simplest possible feature toggle Library in Go
Convenience function using global instance
feato.RegisterGlobal([]*feato.Feature{
{Name: "group01", Childs: []*feato.Feature{
{Name: "name03", Flag: feato.Enabled},
{Name: "name04", Flag: feato.Disabled},
}},
})
if feato.IsEnabled("group01.name03") {
fmt.Println("group01.name03 is enabled")
}
// Output: group01.name03 is enabledParseable to JSON or other format
flagMap := make(feato.FlagMap, 0)
feato.Register(flagMap, []*feato.Feature{
{Name: "name01", Flag: feato.Enabled},
{Name: "name02", Flag: feato.Disabled},
{Name: "group01", Childs: []*feato.Feature{
{Name: "name03", Flag: feato.Enabled},
{Name: "name04", Flag: feato.Disabled},
{Name: "sub01", Flag: feato.Enabled, Childs: []*feato.Feature{
{Name: "name05", Flag: feato.Enabled},
{Name: "name06", Flag: feato.Disabled},
}},
}},
})
b, _ := json.MarshalIndent(flagMap, "", " ")
fmt.Println(string(b))
// Output: {
// "group01.name03": true,
// "group01.name04": false,
// "group01.sub01": true,
// "group01.sub01.name05": true,
