Why does yq output ... at the end?

[rayzorben]

Example:

user:
  name: Ray

Output

~/source » yq -Y .user.name arch.yml                                       2 ↵ rayben@rayarchpad
Ray
...

[rayzorben]

Similarly, yq -y with some expressions puts - at the beginning:

user:
  name: Ray

Output of yq -y '..' file.yml

user:
  name: Ray
---
name: Ray
--- Ray
...

But this one is really odd:

yq -Y '.. | tostring | startswith("!secret")' file.yml outputs:

~/source » yq -Y '.. | tostring | startswith("!secret")' arch.yml              rayben@rayarchpad
false
--- false
--- false
--- true
--- false
--- false
--- false

Please see #104.

Any idea on the second issue though or are they related and will both be fixed at the same time?

That is a different issue, actually. You asked yq to translate a stream of multiple JSON documents back into YAML. But in YAML, unlike JSON, there is no unambiguous way to distinguish between a document boundary and a continuation of the existing document. So you will see PyYAML emit document separators (---) in this case. Like #104, it's not a bug but an artifact of YAML/PyYAML's behavior, but unlike #104, I don't think there's anything expected in the future to control this behavior. To avoid it, you can just not use -y/-Y.

It may be that in your last example there are missing newlines, though. I'll take a look at that (#110).

Thanks, I guess what I am looking for may not be possible at this time (or have to use sed/grep/etc):

I want to take the following:

user:
  password: !secret U4e80asdfnkjlasdf832r/u0q80sa
  name: ray

...

And I want to say 'are there any values in this document (one or more) that contain the tag !secret (which I know is a yaml thing and not a json thing).

And then I want to say

cat file.yml | yq '.user.password | tags' > would return !secret
cat file.yml | yq .user.password > would return U4e80asdfnkjlasdf832r/u0q80sa

That way I know what I am reading is an encrypted value.
