I want to be able to get positional information on a yaml node i.e. the line in its text and its column.
I think this is more or less implemented in the official yaml golang library. Line and Column

func main() {
yml := `
store:
book:
- author: john
price: 10
- author: ken
price: 12
# comment
bicycle:
color: red
price: 19.95
`
path, err := yaml.PathString("$.store.book")
fmt.Printf("%#+v\n", path.String())
if err != nil {
log.Fatal(err)
}
var authors []interface{}
if err := path.Read(strings.NewReader(yml), &authors); err != nil {
log.Fatal(err)
}
fmt.Println(authors)
// [john ken]
}I want to be able say to get something like path.Line (2) and path.Column (3)

@pantelis-karamolegkos use node token for this :)
Great! Thanks for the suggestion 🎉
@nervo I just noticed that in the go playground example, the column value for the .store.book node is 5 while clearly it is in 3rd column; why is that?
@pantelis-karamolegkos the .store.book path represents the VALUE node, it begins where the value begins, aka. right after the first -.
So is there a way for me to get the indentation of the line where .store.book actually resides? a.k.a 2?
@pantelis-karamolegkos navigate through token's tree :)
