Expansion - Access AdditionalSourcecode file

[d.healey]

@DanH You're not confused, but you could just take Lindon's code and adjust it to load from an expansion (and don't use var) :)

    local e = expHandler.getCurrentExpansion();
    local data = e.loadDAtaFile("NewNumber.json");

    if (isDefined(data))
    {
        // Do the thing
    }
    else
    {
        // Do the other thing
    }

@DanH my takeaway from this is that Engine.loadFromJSON can handle a file not being there but currentexpansion.loadDataFile cannot, and produces an error...

[DanH]

@d-healey yup, but I can't get past .loadDataFile if there's no data file

HISE doesn't seem to like it (unlike Engine.loadFromJSON)

[d.healey]

@DanH Which line gives the error and what is the error?

[DanH]

@d-healey
Error:

Interface:! Cant find data file {EXP::TEST}NewNumber.json

Line:

local data = e.loadDAtaFile("NewNumber.json");

[d.healey]

@DanH I see the problem. I've got to go out now but I'll take a look in the HISE source when I get back in a few hours and see if there is an easy fix.

[DanH]

@d-healey ok thanks!

[d.healey]

This is how Engine.loadFromJSON handles a missing file.

And this is how loadDataFile handles it:

So it reports an error but does it actually stop the rest of your script running? In other words, if you put Console.print("HELLO WORLD"); on the next line does anything print to the console?

[DanH]

@d-healey yeah it stops it - i.e no "Hello World"

[d.healey]

@DanH Okay, I think we should make it so it behaves the same as loadFromJSON and leave it up to the scripting to validate the file. I'll make a pull request with this later.

[d.healey]

@DanH Yeah removing those lines makes it work like the other function which I think is much better behaviour. I've made a pull request and the change is also in my fork.

[DanH]

@d-healey great, so just remove the reportScriptError line?

[d.healey]

@DanH Just do what I did - https://github.com/christophhart/HISE/pull/286/commits/3ebdf557839a53c2d94c123e72391b62919aa725 (the red stuff is the parts I deleted)
