So.. I hope the next release will take some time.
I had some work to merge the changed parts into the existing german translation

Just joking.
Thanks for this new version!

big release Chris, congratulations!
thx

[Chris]

Here are the changes for v1.0.47.06:

Fixed crash when a function was called concurrently with an optional ByRef parameter omitted by one thread but not omitted by the other. [thanks DeathByNukes]

Fixed "Menu, Tray, MainWindow" to enable the menu items in the main window's View menu. [thanks lexiKos]

Added dynamic function calling. [developed by lexiKos]
Description: A function (even a built-in function) may be called dynamically via percent signs. For example, %Var%(x, "fox") would call the function whose name is contained in Var. Similarly, Func%A_Index%() would call Func1() or Func2(), etc., depending on the current value of A_Index. The called function's definition must exist explicitly in the script, either via #Include or a non-dynamic call to a library containing the function. If the function does not exist -- or if the wrong number or type of parameters is passed to it -- the expression containing the call produces an empty string.

Thanks for the update.. and nice to see you back in action Mr.Chris
Dynamic function Calling! Ooh.. Thanks lexiKos

[daonlyfreez]

Excellent! Especially the dynamic function calling

And, also from me: good to see you are still around, Chris. I hope you can keep up the good work somehow.

Oh great thx, long waited internal support of dynamic function call. Go(o)d to see you back, Chris.

lexikos, your`re great!!

Thanks for the update Chris and lexiKos!
and Chris, we all missed you.
I'm glad to see you back.

[Zoulou]

Exactly the same as Rajat.
Just a little noob question : please Chris, do you continue to work on V2 of AHK, and, if it is the case, do you think that we will see it in few/a lot of months ?
Thanks again

[toralf not loged in]

Hi,
And thanks a lot for the dynamic function calls. Even that I stoped coding, I still have an eye on AHK.
Greetings.

[majkinetor]

Thanks lexikos. Finaly offical recognition for your valuable work.

With dynamic function calling, the possibilities are mind boggling.

[TL]

I'm evaluating whether to switch to the new dynamic function method on my existing project. Some questions:

If I want to validate that a string contains a valid function name without executing the function at that time (for example, a function is registered in some way at program startup), is it best to still use the RegisterCallback function to see if an error occurs or is there a way that is quicker or doesn't depend on the number or type of parameters?

Also, if I use the Register Callback to validate the function's name should I then just use the old style DllCall method to invoke the function or is there an performance gain by using the new dynamic function method?

TL

[Lexikos]

You could use RegisterCallback to validate the function, then free the callback and use dynamic function calls. RegisterCallback fails for built-in functions or user-defined functions with ByRef parameters, while dynamic function calls support both.

Dynamic function calls require the function to be looked up every call. AutoHotkey searches the function list sequentially, so speed may vary depending on the order of functions: Explicitly included user-defined functions are first, followed by library and built-in functions (depending roughly on the order such functions are referenced in script.)

My benchmarks show dynamic function calls are roughly five times faster than DllCall when used with the first function in the script. I recommend benchmarking some scenarios typical to your script before deciding.

If your script would benefit from being able to pass strings to the callback rather than numbers or return values ByRef, dynamic function calls are the way to go.
