JSONPUT suppress empty array occurrences

Reference case TS015700520

Please provide ability to suppress empty occurrences of arrays when using JSONPUT* functions. If any element of the array is present, provide that array occurrence. If all elements of an array are empty, suppress the generation of that entire array or generate an empty array as indicated by the developer. JSONOMIT is used in the examples below, however new attributes can be implemented if needed. A compile parm would not work since the same program (and even the same JSON) could have different rules for how to handle empty values.

Suggested new attributes:

JSONOMIT (specified on an array) – current behavior for existing attribute – generate empty occurrences, suppress if 0 occurrences

JSONARROMIT1 – Suppress empty array occurrences, generate empty array [ ] if 0 occurrences

JSONARROMIT2 – Suppress empty array occurrences, suppress array if 0 occurrences

Given the following structure:

DCL 1 json_struc,

5 elementOne JSONOMIT CHAR(10),

5 listElements(200) JSONOMIT CHAR(11),

5 array2 JSONOMIT,

7 name CHAR(25),

7 phone CHAR(15),

7 bday CHAR(10),

5 lastElement JSONOMIT CHAR(30);

We would like empty occurrences of listEmelements and array2 to be suppressed from the generated JSON. Multiple examples follow:

Assuming 2 listElements items are populated, we would expect the following:

{“elementOne”:”someValue”,

“listElements”: [

“Item1”, “item2”],

“lastElement”:”lastvalue}

Assuming 0 listElements items are populated, we might want the following:

{“elementOne”:”someValue”,

“listElements”: [ ],

“lastElement”:”lastvalue}

Or

{“elementOne”:”someValue”,

“lastElement”:”lastvalue}

Would need a way to indicate which output to provide when 0 occurrences are populated.

Given the following structure (same structure, repeated here for reference):

DCL 1 json_struc,

5 elementOne JSONOMIT CHAR(10),

5 listElements(200) JSONOMIT CHAR(11),

5 array2 JSONOMIT,

7 name CHAR(25),

7 phone CHAR(15), /* required */

7 bday JSONOMIT CHAR(10), /* optional */

5 lastElement JSONOMIT CHAR(30);

Assuming 2 array2 items are populated, and the second occurrence has blank phone and bday - we would expect the following:

{“elementOne”:”someValue”,

“array2”: [

{“name” : “Bob”,

“phone” : “123-555-1212”,

“bday” : “2024/03/14” } ,

{“name” : “Sue”,

“phone” : “” } ,

],

“lastElement”:”lastvalue”}

In the previous example, phone is required to be present even when blank/empty; and bday is optional and should be suppressed when empty.
