[Question] Tags support, explicit ast decoding? about go-yaml HOT 3 CLOSED

Hi @divoxx

There are plans to separate GlobalTag and LocalTag in future improvements,
but for now they cannot be distinguished.
However, you can call GetToken() of ast.TagNode and
get the tag string with token.Value .
You can determine whether it is LocalTag by looking at its contents.

Also, if you want to use an already manipulated AST,
can I solve it by preparing an I/F like (*Decoder).DecodeWithFile(interface{}, *ast.File) ?

from go-yaml.

Thanks for the quick answer and the explanation for global vs local tags.

As far as the decode method, I think accepting a *ast.Node would be more flexible. For example, I might want to parse the whole document (*ast.Document) but I also might want to parse just a subset of the document. That said, taking an *ast.File is already helpful.

That said, I'm not sure if it's currently possible to manipulate the ast? For example, would it be possible to replace value node by another programmatically created one, using the public interface of the ast package?

from go-yaml.

I will add more helpful features at next minor update .

Thanks !
