Expansion - Access AdditionalSourcecode file

[David Healey]

Place this at the top of the function and tell me what output it gives.

Console.print(newExpansion.getRootFolder().toString(0));

@d-healey said in Expansion - Access AdditionalSourcecode file:

Console.print(newExpansion.getRootFolder().toString(0));

I get the path of the expansion folder on my drive

[David Healey]

@danh And the path is correct and that's the same root folder of where your data json file is?

Also try this in the top of the function and tell me what the output is

Console.print(trace(newExpansion.getDataFileList()));

[DanH]

@d-healey path is good, I copied the json to that folder as well as the ASC folder

[DanH]

@d-healey

Console.print(trace(newExpansion.getDataFileList()));

an empty array. []

[David Healey]

@danh So it's not finding your expansion's data files. Are your data files in your expansion's additional source code folder or your project's additional source code folder?

[DanH]

@d-healey expansion only

[David Healey]

@danh zip your project (without samples, pool, and binaries folder) and send it to me

[David Healey]

I think you've found a bug. Might be related to this issue - https://forum.hise.audio/topic/5121/confusing-convolution/21

[David Healey]

@Christoph-Hart Here is a minimal example that demonstrates the problem. I think this is related to the other problem some of us have been having with accessing files when using expansions.

@DanH I was playing around with this some more today and it seems to load the data file correct (not sure if this is due to a recent change), but the getDataFileList() function is still returning an empty array.

[DanH]

@d-healey thanks. Would you mind sending me a snippet to look at please?

[David Healey]

@DanH Yeah

@d-healey coming back to this finally - it's working as you explained, and thanks for the project. I'm not massively familiar with using jsons - how do I get the value of "Value" into HISE script so I can assign it to something?

[David Healey]

@DanH From the JSON file you'll just get a standard Javascript object inside your script, so you can use it like any other object. If you want to view the contents you can use the script watch table or just Console.print(trace(objName));

[DanH]

@d-healey that's what I hoped would happen

So if the JSON just contains:

{
  "NumberData" : "10"
}

then in my script I should just be able to go:

reg = MyNewNumber;

MyNewNumber = NumberData;

Or no?!

[Lindon]

@DanH

Off the top of my head...

var myObj = Engine.loadFromJSON("somefile");

Console.print(myObj.NumberData);

[DanH]

@Lindon Thanks! :)

[DanH]

@d-healey @Lindon thanks both, that's working perfectly - in the case that the JSON file is missing how can I set "MyNewNumber" to a certain value? I'm already in an if / else statement. I can't seem to find a way out after calling

var myObj = Engine.loadFromJSON("somefile");

[David Healey]

@DanH You can use if (!isDefined(myObj)) to check if it's there or not.
