Other New release: B4A v14.0 with optional parameters

[Erel]

B4A v14.0 follows B4J v10.7 and adds the optional parameters feature to B4X programming language.

The parser has undergone a major refactoring, resulting in performance improvements and providing the potential for new language features. The first one is optional parameters.

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

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

'From:
Dim j As HttpJob
j.Initialize("", Me) 'unused JobName and always "Me"
j.Download(url)

'To:
Dim j As HttpJob
j.Initialize
j.Download(url)

Thank you.

Starting with version 13.70, the system requirements issue has been fully resolved .
As of this update, you can seamlessly target your applications to targetSdkVersion="36".

As it is not written in the improvements list, it wasn't implemented in this update.

I assume no changes for Android SDK Command Line tools and resources_7_25.zip used in version 13.5.

Regarding the "potential for new language features" you mentioned — could you elaborate on how optional parameters fit into this? Does this mean we can expect more modern language features in B4X's future roadmap? And if so, what other features are you considering or planning?

 

[Erel]

could you elaborate on how optional parameters fit into this?

Yes, a large refactoring was done in order to support optional parameters.
Maybe a variant of varargs (as an alternative to Array()).

Compile time automatic type inference:

Dim x = "aa" 'x is string
Dim i  = 12 'i is int
Dim b = pnl.GetView(i) 'b is B4XView

And other stuff that is too premature to even post it...

Compile time automatic type inference

At the moment, compiler warning "Variable declaration type is missing. String type will be used. (warning #5)" is raised when omitting the type. I hope the automatic type inference will include some kind of "Option Explicit" (as it's called in VBA) to make type declarations mandatory?

 

[Erel]

will include some kind of "Option Explicit"

There will not be an "option explicit" in B4X.

A new automatic type inference feature will make this warning irrelevant. But there is still time for this.
