jsonline's Issues

feat: add wildcard selection for leaf objects

With this input JSON document

{
  "designation": "Acme Inc.",
  "adresseSiègeSocial": {
    "NumeroRue": "123",
    "NomRue": "Main St.",
    "CodePostal": "12345",
    "Ville": "Anytown"
  },
  "employe": [
    {
      "Nom": "Jane",
      "Prenom": "Doe",
      "dateNaissance": "01-01-1970",
      "LieuNaissance": "Anytown",
      "NombreEnfants": 1,
      "enfant": [
        {
          "Prenom": "John",
          "DateNaissance": "01-01-2000",
          "LieuNaissance": "Anytown"
        },
        {
          "Prenom": "Jack",
          "DateNaissance": "01-01-2002",
          "LieuNaissance": "Anytown"
        }
      ]
    }
  ]
}

FindValuesAtPath("employe.enfant") should return

[
  [
    {
      "Prenom": "John",
      "DateNaissance": "01-01-2000",
      "LieuNaissance": "Anytown"
    },
    {
      "Prenom": "Jack",
      "DateNaissance": "01-01-2002",
      "LieuNaissance": "Anytown"
    }
  ]
]

FindValuesAtPath("employe.enfant.*") should return

[
  {
    "Prenom": "John",
    "DateNaissance": "01-01-2000",
    "LieuNaissance": "Anytown"
  },
  {
    "Prenom": "Jack",
    "DateNaissance": "01-01-2002",
    "LieuNaissance": "Anytown"
  }
]

feat: remove fields not declared in template

Problem

we can't use jl command to normalize a json stream with only wanted fields.

$ jl -t '{"name": "string"}' <<EOF
{"name": "Martin", "city": "London"}
EOF
{"name":"Martin","city":"London"}

Proposal

Add --strict flag (-s for short) to filter out not declared fields.

$ jl --strict -t '{"name": "string"}' <<EOF
{"name": "Martin", "city": "London"}
EOF
{"name":"Martin"}

feat : add max size parameter for string and truncate output

Problem

Column definition in database have a max size definition. Trying to insert a bigger value with lino push failed.

Proposal

Define a template with max size parameter that truncate string longer than max size definition.

$ jl -t '{"name": "string(4)"}' <<EOF
{"name": "Martin"}
EOF
{"name":"Mart"}
