call function inside function

[ulrik]

I have this:

inline function onBTNControl(component, value)
{
    //  a lot of code
    function scroll()
   {
        // a lot of code
    }
    // Here is my reference to the "scroll" function like this:
    onBTNControl.scroll = scroll;
}

It's working nicely if I have been running the first BTN function once
But I am unable to get to the inner function if the first has not been executed.
Is there a better way to script this?

Can I declare the inner function outside of the BTNfunction?
How?

Declaring functions inside functions doesn't seem like a good idea. And declaring a non-inline function inside an inline function would seem to be to defeat the advantages of using an inline function.

Declare each function separately.

[ulrik]

@d-healey I want the inner function to execute only inside the other function to avoid using globals.
The inner function use variables that only exists inside the outer function

[d.healey]

@ulrik This is what namespaces are for.

[ulrik]

@d-healey So how do I set it up, do you have a short example where both functions use the same "private" variables?

[d.healey]

There are no private variables in javascript or HISE script. But in HISE script we can create variables that have scope limited to a namespace.

namespace MyNamespace
{
    reg myVariable = 50;

    inline function aFunction()
    {
        Console.print(myVariable); // Will print 50 to the console
    }
}

Console.print(MyNamespace.myVariable); // Will print 50 to the console
Console.print(myVariable);  // Will trigger undefined parameter error�

Note that the variables must be of type reg or const to limit the scope. var will always be global.

@d-healey Thank you David, I will study :)

@d-healey if you create a pull request for the coding standard, I'll merge it into the main doc branch so it becomes part of the HISE doc website.

[d.healey]

@Christoph-Hart Done, thanks!

[Christoph Hart]

Ah damn, I noticed you were using a Markdown feature that the HISE Markdown parser is not supporting (inline code examples in a bullet list):

-   This list item has a code example:

    ```javascript
    CodeExample
    ```

-   Next Item

This makes it look like this in the HISE doc browser:

With a bit of whitespace correction it looks like this:

However then it might not look as good in the Github preview. Hard choice :)

[d.healey]

@Christoph-Hart I think it's more important that it looks good in the HISE docs since that's where I expect most users will find it. Do you want me to clean it up?

[Christoph Hart]

Nope, I'll do it, I have to add the metadata and stuff anyways. It's a pretty quick thing...

[Christoph Hart]

Alright here we go:

https://docs.hise.audio/scripting/scripting-in-hise/hise-script-coding-standards.html

I noticed that in some examples it uses 2 spaces instead of a tab (=4 spaces) now. Should be an easy fix though :)

@Christoph-Hart Thank you!
