JSON Diagrams: Request to differentiate explicitly boolean and string on the output

Question

Hello PlantUML team,

Here is a wanted feature:

• Is it possible to have got a parameter or another thing (manually activate or not; possible to deactivate for people which don't want this functionality), to differentiate explicitly boolean and string on the output, example:

@startjson
{
"JSON_Boolean_value": true,
"JSON_Boolean_value": false,
"JSON_String_value": "true",
"JSON_String_value": "false"
}
@endjson

I am open to all propositions, as: style (italic, ...), font (monospaced [but not so good, if on the future we would to change all the value to be on a monospaced font]), 'b' indices for boolean (as true_b or false_b), ...
→ I don't know what are the best solution.

Thanks for your support,
Regards,
Th.

Answer 1

I don't know what are the best solution.

I don't know either. Maybe https://www.google.com/search?q=true+false+symbol or https://www.google.com/search?q=true+false+symbol&tbm=isch could be a source of inspiration ?

Hello PlantUML team,

Another 'source of inspiration' is the online JSON editors:

• https://codebeautify.org/online-json-editor
• https://jsonformatter.org/json-editor
• https://jsoneditoronline.org/

With that, the boolean value are interpreted as box, as Checkbox, empty for false value, and with a tick for true value.

Then here are some output proposals (first Proposal from your google request inspiration, second Proposal from the Checkbox inspiration):

@startjson
#highlight "Proposal"
{
"JSON_Boolean_value_t": true,
"JSON_Boolean_value_f": false,
"JSON_String_value_t": "true",
"JSON_String_value_f": "false",
"Proposal":null,
"Proposal_value_t0": "<&circle-check> true",
"Proposal_value_f0": "<&circle-x> false ",
"Proposal":null,
"Proposal_value_t1": "<&task> true",
"Proposal_value_t2": "<U+2611> true",
"Proposal_value_f2": "<U+2610> false",
"Proposal_value_t3": "<U+1F5F9> true"
}
@endjson

Another proposal for other people are welcome...

If that can help,
Regards,
Th.

I like Proposal_value_t2 and Proposal_value_f2.

Since we are here, what about the special 'null' value ? Should we use a symbol for it too ?

We've just published a beta.

Tell us what you think about it!

And for null:

• Why not use the Unicode representative character <U+2400> for null:

@startjson
#highlight "Proposal"
{
"JSON_Null_value":       null,
"JSON_String_value":     "null",
"Proposal":              null,
"Proposal_value_null_1": "<U+2400>",
"Proposal_value_null_2": "<U+2400> null"
}
@endjson

Regards,
Th.

Hello PlantUML,

Do you keep the empty set symbol ('ø', '∅'  <U+2205>) or do you want to change to Unicode representative character <U+2400> for nul?

Regards,
Th.

Well, it's really easy to change. On second though, I think we are going to use <U+2400>

It may be more logical. That's what last beta http://beta.plantuml.net/plantuml.jar is doing.

Does it sound good to you ?

Hello PlantUML team,

That is perfect for me.
(apart from a bug on the Samsung side which misunderstands Unicode... and transforms the ballot box (geometric box [square]) on a real physical ballot box! [sacred Unicode interpretation]). [We still find bugs now, but in other applications. ]

Another item ("Since we are here" ), will be to differentiate number and string.

@startjson
{
"JSON_Number_value": 42,
"JSON_String_value": "42"
}
@endjson

But I have no proposal or no idea...

Regards,
Th.
