Does not support top level include with other keys

[renard]

Here is my setup:

• PyYAML: 5.1
• pyyaml-include: 1.1.1
• python: 2.7.15

The python script (from the README):

import yaml
from yamlinclude import YamlIncludeConstructor

YamlIncludeConstructor.add_to_loader_class(loader_class=yaml.FullLoader)

with open('0.yml') as f:
     data = yaml.load(f, Loader=yaml.FullLoader)

print(data)

0.yml:

!include 1.yml
foo: bar

1.yml:

name: "1"

It seems that mixing toplevel include and other value is not (yet?) supported.

I got this error:

Oh, it's a bad example in readme, and i'll remove it later.

Till now, !include constructor can NOT be used at the TOP level, unless it's the only one node in whole YAML document.

so:

!include include.d/1.yml

is correct

!include include.d/1.yml
# any other node

is WRONG

but

1: !include include.d/1.yml
2: !include include.d/2.yml
foo: boo

is correct

I get the same problem when doing:

thing: !include include.d/1.yml
       name: !include include.d/name.yml

Is that expected?

No, it's not a valide YAML, i think.

Because the include constructor can not include YAML files literally -- it loads anoter YAML file, and parses it to a python object, then put it into original YAML document.

So, the above YAML snippet will be taken as:

thing: <included and parsed object>
   name: <another included and parsed object>

which is invalid.

BTW, if want to include literally, a template engine maybe better.
