Convert JSON Data two-dimensional array into KCL Data

[Mr-Czt]

Bug Report

1. Minimal reproduce step (Required)

${workspace}/models/class_models.k

schema classmate:
    classname: str
    students: [[student]]   # Group data using two-dimensional arrays

schema student:
    name: str
    age: int

kcl data file, ${workspace}/json_2_array.k:

import models.class_models as c_model

cm = c_model.classmate {
    classname = "一年级一班"
    students = [
        [
            c_model.student {
                name = "xiaoming"
                age = 6
            },
            c_model.student {
                name = "xiaohua"
                age = 5
            },
        ],
        [
            c_model.student {
                name = "xiaohong"
                age = 6
            },
        ]
    ]
}

execute kcl json_2_array.k -o json_2_array.json, convert json result success!
get json file, ${workspace}/json_2_array.json:

{
    "cm": {
        "classname": "一年级一班",
        "students": [
            [
                {
                    "name": "xiaoming",
                    "age": 6
                },
                {
                    "name": "xiaohua",
                    "age": 5
                }
            ],
            [
                {
                    "name": "xiaohong",
                    "age": 6
                }
            ]
        ]
    }
}

Then, execute kcl import -m json json_2_array.json -o json_2_import.k -p ./models/, convert json data to KCL data

2. What did you expect to see? (Required)

I hope convert models like json_2_array.k

maybe like:

"""
This file was generated by the KCL auto-gen tool. DO NOT EDIT.
Editing this file might prove futile when you re-run the KCL auto-gen generate command.
"""
# question1: I hope the generated KCL data can automatically include the imported model relationships.
import models.class_models as c

classmate = c.classmate {
    classname = "一年级一班"
    # question2: I hope to support the import of two-dimensional arrays.
    students = [
        [
            c.student {
                name = "xiaoming"
                age = 6
            },
            c.student {
                name = "xiaohua"
                age = 5
            },
        ],
        [
            c.student {
                name = "xiaohong"
                age = 6
            },
        ]
    ]
}

3. What did you see instead (Required)

it(kcl import json_2_array.json -o json_2_import.k --force) works, but I get json_2_import.k is :

"""
This file was generated by the KCL auto-gen tool. DO NOT EDIT.
Editing this file might prove futile when you re-run the KCL auto-gen generate command.
"""

{
    classmate = {
        classname = "一年级一班"
        students = [
            [{"name" = "xiaoming", "age" = 6}[{Key = "name", Value = "xiaoming"}, {Key = "age", Value = 6}], {"name" = "xiaohua", "age" = 5}[{Key = "name", Value = "xiaohua"}, {Key = "age", Value = 5}]]
            [{"name" = "xiaohong", "age" = 6}[{Key = "name", Value = "xiaohong"}, {Key = "age", Value = 6}]]
        ]
    }
}

looks like two-dimensional arrays not work.

4. What is your KCL components version? (Required)

kcl version 0.12.3

BTW:
ust kcl import, convert (json, yaml...)data to KCL data, Can the generated KCL data file automatically identify the dependent models and supplement the import information?

pseudocode：

1、design models in ${workspace}/models/
2、file.k which import models.xxx as x, then use model x.yyy, the file.k define custom default value.
3、kcl file.k --format json, get file_1.json, use to parsing and generating UIs, give to customer configuration.
4、after step3, UI -> file_2.json, which contains custom's modify. I can use kcl import file_2.json -o file_2.k. get KCL  data. I hope save file.k and file_2.k, if Show in UI's, just kcl run it again.

All of this, If file.k, execute run get file.json, then execute kcl import get file_import.k, file.k == file.import.k (Is this possible?), then run file_import.k -> file_import.json, file_import.json == file.json.
No data will be lost through any of these conversions.（Include Import Imported Dependencies）
