Large compiler refactoring

[Erel]

Just finished a large refactoring related to the way variables and parameters are handled internally. Zero effect on B4X code behavior, but will make it easier to introduce new features. More to come...

Excellent news @Erel , thank you...

Default parameters?

 

[Erel]

Yes. Optional parameters.

 

[Daestrum]

Optional as needed on definition, not needed on call?

What did I win?


I'm really looking forward to seeing what other great new things like this there will be.

A naughty question: will CallSub and CallSubDelayed also be able to call Subs that have optional parameters?

The anticipated reform. Does it imply that the intelligent evolution of the b4x ecosystem can be controlled through parameterization.

 

[Erel]

Optional as needed on definition, not needed on call?

Yes.

No. Optional parameters are set during compilation so dynamic calls must include all parameters.

Boring:

Dim b() As Byte = "aaaa".GetBytes("UTF-8")
'''
Dim s As String = BytesToString(b, 0, b.Length, "UTF-8")

Not boring:

Dim b() As Byte = "aaaa".GetBytes
'''
Dim s As String = BytesToString(b)

 

[Alessandro71]

does this also means that it will be possible to call "Initialize" on a generic "Object" by using CallSub without knowing it's actual Class?

 

[Erel]

No. It has nothing to do with it. You should create a Factory class that instantiates new objects based on some parameter. More information in a new thread.
