Output Format

The tool returns a JSON object. If it managed to resolve the package successfully, then it returns a JSON in the following format. Note that in packages key, there is also the package that was given as input.

{
    "input": "debianutils",
    "status": true,
    "packages": {
        "libc6": {
              "package": "libc6",
              "version": "2.28-10",
              "arch": "amd64",
              "release": "buster",
              "source": "glibc",
              "source_version": "2.28-10",
              "date": ""
            },
        "debianutils": {
              "package": "debianutils",
              "version": "4.8.6.1",
              "arch": "amd64",
              "release": "buster",
              "source": "debianutils",
              "source_version": "4.8.6.1",
              "date": ""
        }
    }
}

Otherwise, it produces a JSON with an error message.

{
    "input": "buz",
    "status": false,
    "error": "E: Unable to locate package buz"
}
