Re: Array editing or Validate JSON string?

[Mark Talluto via use-livecode]

I always appreciate error reporting. I ran into the same problem. Sometimes you 
can see the error easily enough. But, in complex arrays, it is harder to see 
the error when looking at JSON. For this reason, I find dropping it into a 
validator to be useful. They can point you in the right direction to fix the 
JSON.

But, if you are trying to pick up on this programmatically in an app, the best 
you can do is check for success or failure by looking for data in the array. If 
it is not there, an error took place.

Re: Array editing or Validate JSON string?

[J. Landman Gay via use-livecode]

When I needed to check JSON validation, I put the JSONToArray function 
inside a "try" structure. The catch clause will trigger and tell you 
there's an error. It isn't too much different than what the editor does but 
It can give you a clue.

Re: Array editing or Validate JSON string?

[bob--- via use-livecode]

Livecode provides a text editor to, well, edit text. It does not understand the 
syntax/grammar of languages (Livecode, HTML, Javascript, JSON, YML, etc). What 
you need is an editor that “knows" JSON. 

Your best bet is to copy the text into Sublime, Visual Studio Code or Atom 
which do understand JSON’s syntax/grammar. There may be some configuration to 
the tool you will need to do but you will get indications from these editors 
when you have malformed JSON.

Re: Array editing or Validate JSON string?

[William Prothero via use-livecode]

Folks:
I guess I could have been more clear. I am editing the JSON directly in a text 
field. If I make a mistake, then use JSONToArray, the program just fails 
silently. What I would like to do is get a dialog that the JSON wasn’t formed 
correctly. Of course, since I’m using it for my personal development of my app, 
I can know that it failed if I don’t get the answer dialog I put in after it. 
but, it seems a kludge. Shouldn’t there be some kind of an error result if the 
JSON is ill-formed?
