@ustk No reg doesn't pollute the script-wide namespace.

namespace test
{
	var myVar = 10;
	reg myReg = 50;
}

Console.print(myVar);
Console.print(myReg);

Somebody documentented this stuff and nobody reads it :p - https://docs.hise.audio/scripting/scripting-in-hise/hise-script-coding-standards.html

@d-healey - these were reg to start with so that's not it, and @ustk ANY name myVar thisVar, myThis, SOmething, Anything

[ustk]

@d-healey Oh gosh I never ever noticed that! But I generally use var only in functions that are not inline

How many did you have? The limit is 32 per namespace. But I don't think this is the issue. I was just suggesting you use namespaces and separate files to make your code more manageable.

[Lindon]

OKay - confirmed - exactly the same behaviour on Windows as MacOS.

[Lindon]

@d-healey - so tell me this about namespaces -

I have (say) a Script processor with code in init, onNoteOn and onNoteOff

where am I putting this namespace ? in the Init? Does that work? Will I need to prepend the namespace name in onNoteOn and onNoteOff?

Here's what I wrote about namespaces in the doc I posted above

• There is no performance penalty for using namespaces.
• Namespaces should be written in Pascal case .
• If the namespace resides in a dedicated external file the file should have the same name as the namespace, e.g. PageHandler.js .
• Namespaces cannot be nested.
• Don't declare var variables inside a namespace. Use reg instead.
• Each namespace can have up to 32 reg variables

A namespace is a bit like a singleton class.

Here's a screenshot of the on init section from a largish project I'm working on. Every single one of those include lines you see refers to a separate file. So all my LAF code (and some related paint routines and theming stuff) goes inside my LookAndFeel.js.

Everything related to presets and the preset browser goes inside Presets.js.

It makes it really easy to organise the code, and when you're debugging you can comment out a whole file's worth of code just by commenting out the include line.

All the other default callbacks are unaffected but you can call code from your external files in those callbacks.

So if you had a namespace for handling keyswitches; in the on note on callback you could call something like Keyswitches.changeArticulation().

@d-healey - well thats pretty much how I use them... maybe not as well or as often but really I'm asking about whats not in the documentation:

having a name space declared in the on init section of a script processor...

namspace myThing
{
    reg myVar;
}

means in the onNoteOn callback I have to say this:

Console.print(myThing.myVar);

Correct?

[ustk]

@lindon exact

[Lindon]

@ustk @d-healey well I've created a whole swag of namespaces, and its still crashing....its just massively unreliable at large project scales...

[Lindon]

@lindon - and when it does run it runs like a dog...its incredibly slow - and yes this is NOT the debug HISE...

Was this the same in the master branch?

[Lindon]

@d-healey nope master runs OK.
