[Beta] JSON Object

[LB]

Thanks to Phi and ConceptGame for helping to debug this extension.

JSON object currently can read JSON files from strings using James' json-parser library that comes with the EDIF SDK. This library only supports reading JSONs, not modifying or creating JSONs, so for that I will have to redesign somewhat.

The lastest version of the extension will always be at this URL: http://www.LB-Stuff.com/MMF2/Extensions/JSON_Object.zip

Please test the object and make sure it works correctly and report any issues here. Make note of the version number in the extension properties.

Enjoy

Finally extension is debuggued.
So.. I was a good job to come back to the front this topic (http://community.clickteam.com/threads/60946-Request-Beg-JSON-Object) forgotten in the matrix of Clickteam forums
Also, thanks for all help Phi and conceptgame, and for sure to LB for making dream live true!

I don't have the time to check it from now, but I will do later for sure

LB, I'm trying your beta json object.
I have a json string like this :

{
    "elem1": [
        {
            "uid": "1",
            "id": "1"
        }
    ],
    "elem2": [
        {
            "uid": "2",
            "id": "2"
        }
    ]
....

The thing is I need in a loop to get every stringvalue$ of an object -
If have correctly understood (I don't know how to do this differently), in order to get return each stringvalue$, I have to do this :

Go to Root
Enter Object named ("elem"+loopindex)
Enter Array index (0)
Enter Object name("uid")
Go to Root
Enter Object named ("elem"+loopindex)
Enter Array index (0)
Enter Object name("id")
....

I'm just wondering why have I to set each time Go to Root, Enter Object named and array index....???
Because I'm just finally stucked since I'm blocked with the 127 limit actions because of these repeated lines of action...

Did I do something wrong ? or is just how your plugin working ? If so, do you think you can do something about this ?

Hopefully my english is clear, it's the end of my working day!
Thanks for your time!

Yes, that is what you have to do, but I don't understand why you are trying to hard-code the loop instead of dynamically processing them? Also, if you can, you may want to change your JSON structure to something easier to work with - for instance I don't understand the purpose of the array wrapping the object for each element.

If you can think of a better way to access data from the JSON within MMF2/CTF2.5, let me know - dealing with nested structures in Fusion is not as straightforward as in programming languages.

Slightly off-topic, but I still think a Javascript scripting extension (that doesn't require MMF2 Developer and isn't based on Microsoft's Javascript engine) would be a better way to go.
I'm already using the WebView object for exactly this sort of thing, and it's so simple just to write a couple of Javascript functions to read & write variables in MMF2 - and you can use JSON.stringify() / parse() to easily save and load everything.

As you say, JSON doesn't really mesh well with MMF2 (the XML extensions are also pretty cumbersome, for the same reason), so I think it's actually easier to write some of the functions yourself.

[LB]

The world of web development is moving from XML to JSON, regardless of programming language, so any scripting extension for any language with JSON support will do.

I'm still trying to think of less cumbersome ways to access JSON via an extension. The major roadblock is that JSON object keys are unlimited in the characters they can contain, so I can't do something as simples as "blah.meh.hello" because in many real-world cases JSON object keys contain spaces, periods, etc.

I am thinking of perhaps easing access to JSONs with known structures by allowing he creation of access templates, but how this will work I am still mulling over in my head.

but I don't understand why you are trying to hard-code the loop instead of dynamically processing them?

Because it seems like I didn't find any other solution.

I used your json plugin in order to load a project in my application.
In the json string (my example above was only an example), I have 17 values/strings for each object. I use a loop to load each object in F2.5, in this loop I have to - among other things - save each of 17 values in 17 different variable of my object.
That's why I'm hard coding this looping process - I would think your extension would only need to declare "Go to Root", "Enter Object...", "Enter array index()" only once by event, and then just return the value from a manually "Enter Object named("---")" action.

If you have a solution....

You don't have to continually start over from the root, you can go back up to the parent object instead.

This is very great LB. Can you add json_encode/create ?
