  Hello my program compiles but does not work

  in fact I would like to be able to make a table from panel including tables

  
  import json
  
  var jsonTest = %* {
    "titleTerm": "DESIGNER",
    "panel": [] }
  
  add(jsonTest["panel"], %* {
              "name": "TEST",
              "posx": 1,
              "posy": 1,
              "height": 42,
              "width": 132,
              "cadre": line1,
              "title": "TEST-Panel",
              "button" :[], "label":[],"field":[]})
  
  add(jsonTest["panel"]["button"] , %* {"Tkey": "F3","txtKey": "Exit","actif": true})
  add(jsonTest["panel"]["button"] , %* {"Tkey":"F9","txtKey": "Add","actif": true })
  add(jsonTest["panel"]["button"] , %* {"Tkey": "F10","txtKey": "Update","actif": true})
  add(jsonTest["panel"]["button"] , %* {"Tkey": "F12","txtKey": "Return","actif": true })
  
  echo jsonTest
  
  quit()
  Run

  This works, but I lose panel in table

  
  import json
  var jsonPanel = %* {
    "titleTerm": "DESIGNER",
    "panel": {
              "name": "TEST",
              "posx": 1,
              "posy": 1,
              "height": 42,
              "width": 132,
              "cadre": line1,
              "title": "TEST-Panel",
              "button" :[], "label":[],"field":[]}
              }
  
  
  add(jsonPanel["panel"]["button"] , %* {"Tkey": "F3","txtKey": "Exit","actif": true})
  add(jsonPanel["panel"]["button"] , %* {"Tkey": "F9","txtKey": "Add","actif": true })
  add(jsonPanel["panel"]["button"] , %* {"Tkey": "F10","txtKey": "Update","actif": true})
  add(jsonPanel["panel"]["button"] , %* {"Tkey":"F12","txtKey": "Return","actif": true })
  
  # test format Json
  echo jsonPanel
  
  for n in 0..len(jsonPanel["panel"]["button"])-1:
    echo jsonPanel["panel"]["button"][n]["Tkey"].getStr()
  
  quit()
  Run

  in fact by exposing you my problem I found, the panel index was missing ex:

  add(jsonTest["panel"]|index]["button"]

  You can use std/jsonutils for Json <-> Table conversion

  Or you can drop std/json entirely and use the superior solution jsony

  By the way, wouldn't it be better to make quoted keys "key": some optional? And allow just key: some?

  How would you distinguish between variables and literals?

  Yep, it's the typical case of either assuming every identifier given as a key is actually a string and disallowing variables as keys.

  Or alternatively requiring a way to quote variables from the local scope (or possibly any expression returning a string).

  Or as a final alternative doing the hacky thing that's kind of fun, but not advised for serious code: abuse declaredInScope for a CT check if something is a local variable or not.

  How would you distinguish between variables and literals?

  I think variable-key used rarely and could be ignored. So keys could always threated as literals. In JavaScript, it's possible to distinguish between literal and variable as { [key]: "some" } but it's almost never used or needed. If you need to set variable key, just use var o = %{ a: 1 }; o[somevar] = 2
