JSON Name Mangling

When Dyalog converts from JSON to APL data, and a member of a JSON object has a name which is not a valid APL name, it is renamed.

Example

In this example, the JSON describes an object containing two numeric items, one named a (which is a valid APL name) and the other named 2a (which is not):

{"a": 1, "2a": 2}

When this JSON is imported as an APL namespace using ⎕JSON, Dyalog converts the name 2a to a valid APL name. The name mangling algorithm creates a name beginning with ⍙.

      (⎕JSON'{"a": 1, "2a": 2}').⎕NL 2
a  
⍙2a

When Dyalog exports JSON it performs the reverse name mangling, so:

      1 ⎕JSON ⎕JSON'{"a": 1, "2a": 2}'
{"a":1,"2a":2}

Should you need to create and decode these names directly,7162⌶ provides the same name mangling and un-mangling operations. See JSON Translate Name.

      0(7162⌶)'2a'
⍙2a
      1(7162⌶)'⍙2a'
2a
