[Suggestion]Array/List nodes to be wrapped as [0]..[n] in Code-Tree for JSON data

[jordan.xue]

Thanks to CudaText, it is a definitely great product.

In latest 1.206.2.0 version, I meet such a pain point. If data type is array/list in JSON, all nodes will be displayed in flat style, not structured or wrapped, not easy to address array node by sequence number.

Suggestion:
If data type is array/list in JSON, the element nodes are wrapped with sequence number like [0],[1]...[n]. User click '[0]' icon to unfold specified element data.

Thanks.

code-tree for JSON is built by lexer (lexlib/JSON.lcf file).
it don't have the power to calculate [0]...[n] indexes. so it cannot do it.
what you can do:
write the tree-helper in python language.
https://wiki.freepascal.org/CudaText_API#TreeHelpers

when done, maybe you will need to disable the code-tree in JSON.lcf lexer.
https://wiki.freepascal.org/CudaText#Le ... d_creation
open JSON lexer in SynWrite app's editor, and 'disable' all items in the ui-tab for code-tree.

i think that tree-helper will be slower than lexer's work. so I don't want to use your work in distro.

I tested with simple JSON array

Code: Select all

{
    "p": [
      "1", "2", "3"
    ]
}

and here I don't see list items in the code-tree. Tree shows only "p".

@Alexey,
Appreciated for your advice.

Take below json as example.

Code: Select all

{
    "list": [{
        "node1": {
            "a": 1
        },
        "node2": {
            "a": 1
        }
    }, {
        "node1": {
            "a": 1
        },
        "node2": {
            "b": 1
        }
    }, {
        "node1": {
            "a": 1
        },
        "node3": {
            "c": 1
        }
    } ]
}

In Code Tree, it listed like below, it is not easy to identify node1,node2 under which element in list.

Code: Select all

"list"
     "node1"
     "node2"
     "node1"
     "node2"
     "node1"
     "node3"

It would be more clear and friendly if display as below (as VS Code):

Code: Select all

"list"
     [0]
        "node1"
        "node2"
     [1]
        "node1"
        "node2"
     [2]
        "node1"
        "node3"

Is it possible to enhance JSON lexer to support '[]' array node type view in code-tree.
thanks.

no, it is not possible to configure lexer in EControl format like this. no counters there.
the solution can be this: create custom tree-helper for JSON lexer (written in Python).
