Put document question

[link4531]

Working off the 'put document' examples provided in the documentation

lets say I have a
doc.yaml

name: tom
color: red

Running the command:
echo '{"people":[]}' | dasel put document -p json -d yaml '.people.[]' $(cat doc.yaml)

returns

{
 "people": [
   {
     "name": null
   }
 ]
}

however if I run the command

echo '{"people":[]}' | dasel put document -p json -d yaml '.people.[]' 'name: tom
color: red' 

everything runs as you would expect...

dasel

• begins to parse the file
• it accepts the format of doc.yaml being yaml
• dasel spits out a null.

Questions
is this intended? am I being dumb?
does this functionality require the features from the 'document merge' branch?

You need to wrap the cat argument in double quotes so as it's picked up as a single string:

$ echo '{"people":[]}' | dasel put document -p json -d yaml '.people.[]' "$(cat doc.yaml)"
{
  "people": [
    {
      "color": "red",
      "name": "tom"
    }
  ]
}

In your example, dasel is essentially given a null value which is why you got that result.

... oh man. I knew I was doing something dumb... But your answer makes complete sense. Thank you
