MapSliceExtractFunc is a function for query.CustomExtractFunc option to extract values from yaml.MapSlice.

Example

b := []byte(`- foo: bar`)
var v interface{}
if err := yaml.UnmarshalWithOptions(b, &v, yaml.UseOrderedMap()); err != nil {
	log.Fatal(err)
}

q := query.New(
	query.CustomExtractFunc(yamlextractor.MapSliceExtractFunc(true)),
).Index(0).Key("FOO")
got, err := q.Extract(v)
if err != nil {
	log.Fatal(err)
}
fmt.Println(got)

Output:

bar
