How to convert this jq query to dasel V2?

[stecydube]

Hi!

I am trying to exclusively use dasel to read a yaml file but I sadly had to convert the yaml to json and process it with jq as I haven't found a way to do it in dasel V2.

Here's part of a bigger yaml, with only the relevant part:

installation:
  methods:
    - method: gitea_deb_package
      os: [debian, ubuntu]
    - method: gitea_arch_package
      os: [arch]
    - method: gitea_release_binary

Here's the command I'm using to read the installation methods list:

metadata_yml=$(cat << 'EOF'
installation:
  methods:
    - method: gitea_deb_package
      os: [debian, ubuntu]
    - method: gitea_arch_package
      os: [arch]
    - method: gitea_release_binary
EOF
)
os_id="ubuntu"
compatible_methods_json=$(echo "$metadata_yml" | dasel -r yaml -w json '.installation.methods' | jq -c --arg os "$os_id" '[.[] | select( (.os // ["any"]) | any(. == $os or . == "any") )]')
echo "$compatible_methods_json"

Result of dasel -r yaml -w json '.installation.methods' with the given input:

[
  {
    "method": "gitea_deb_package",
    "os": [
      "debian",
      "ubuntu"
    ]
  },
  {
    "method": "gitea_arch_package",
    "os": [
      "arch"
    ]
  },
  {
    "method": "gitea_release_binary"
  }
]

Output/content of compatible_methods_json (formatted for easy read):

[
  {
    "method":"gitea_deb_package",
    "os":[
      "debian",
      "ubuntu"
    ]
  },
  {
    "method":"gitea_release_binary"
  }
]

Is it possible to do it all in a dasel select query?
I will still output the final result to json.

Sorry for the delayed response here.
I'm focusing on dasel v3 right now, and this is achievable with:

in.yaml

installation:
        methods:
          - method: gitea_deb_package
            os: [debian, ubuntu]
          - method: gitea_arch_package
            os: [arch]
          - method: gitea_release_binary

cat in.yaml |
  OSID=ubuntu dasel -i yaml -o json 'installation.methods.filter($this.os.contains($OSID) ?? true)'

Output

[
    {
        "method": "gitea_deb_package",
        "os": [
            "debian",
            "ubuntu"
        ]
    },
    {
        "method": "gitea_release_binary"
    }
]

V3 isn't officially released yet but you are able to install the development version.
