Extending structs with 'easy to use function pointers with auto-self-reference' also provide an alternative to the Module thing and you'll get multiple instancing capability for free... The Module, as is, is kind of lacking anyway in regard to scope handling (compared to same idea in Pascal (Unit)).

We are not really talking about OOP. OOP with Classes, Methods, etc. was discussed 10 or 15 years ago and
the result was it will not be supported by PureBasic. It is a waste of time to discuss this over and over again.

Maybe the PureBasic language is already considered finished, I don't know. If not, we can talk about new ideas.
That's why I was bringing Rust into the discussion: Rust has no classes, but it has some features that combine
data structures and functions that work with that data structures:

Something simple like Procedures for Data Structures could probably fit nicely into PureBasic's procedural approach. But that's just my opinion.

Code: Select all

Structure Rectangle
    width.i
    height.i
EndStructure

Procedure.i Area() For Rectangle
    ProcedureReturn Self\width * Self\height
EndProcedure

Define rect.Rectangle
rect\width  = 30
rect\height = 50

Print("the area of the rectangle is " + rect\Area() + " square pixels.")

All it needs is a keyword like Self, This, or Me to access the data structure.
Internally Self is just a pointer to the data structure type. In the example above it would be *Self.Rectangle (internal to the compiler only).

A call of a Data Structure Procedure would look like this inside the compiler:

Code: Select all

Define rect.Rectangle                                       ; Inside compiler:
                                                            ;
Debug rect\Area()                                           ; Debug Area( @rect )  ; internal name: __procedure35
                                                            ;
Define *r.Rectangle = AllocateMemory( SizeOf(Rectangle) )   ;
                                                            ;
Debug  *r\Area()                                            ; Debug Area( *r )     ; internal name: __procedure35

Not fancy OOP with encapsulation etc., because the makers of PureBasic don't want that. But it would bind Procedures to Data Structures in a very simple manner.

The advantage is that everybody can just write new Procedures for existing data structures and add more and more functionality - just by writing simple, additional procedures in the usual PureBasic style.

I agree!
PB is 100% procedural and this new transpiler is just a step into reaching more CPU architectures.

I just hope that inline asm will be continued. (albeit just for the sake of legacy code)

Exciting times!

Fred said "- Inline ASM won't be supported directly at start. We plan to add naked ProcedureASM : EndProdecure which will create an assembly file, use fasm and link it to the final exe without needed to do anything"
That sounds awesome to me because it means existing PB-asm code should mostly still be compatible.
gcc (the C compiler PB will be using) also supports its own form of inline asm, but it's a bit quirky!

Very nice indeed

And similar to how Nim works which is another language that translates to C.

That out of the way, I have another question for Fred : Will all standard C language types be available, especially unsigned long ?

Best regards

btw, I hope Fred changes the software title to something new, and charges us some money for it!$ (because it is literally a brand new software project)
I'm getting tired of feeling guilty for all these free software updates from Fred

He's got a family to feed and its incredible how much work he's done for us over the DECADES _at no expense to us_
PLEASE Fred, we want to pay for your BRILLIANT WORK!!!!!!!!! because without your brilliant work, many of us wouldn't have been able to find our own niches

And we want to _SUPPORT_ PB!!! SHUT UP AND TAKE OUR MONEY!!!

♥

I agree with Keya. The new version should be PureBasic v6.00 and come with a new license model. Fred could "grandfather" existing paid customers if he prefers (ie. not charge us) but make all new buyers have a renewal fee every year. It makes better business sense.

Especially for you and others who getting tired of feeling guilty.

Why aren't you sending donations to Fred?

Posted: **Wed Mar 17, 2021 3:45 pm**

User_Russian: yes but that's just voluntary, so most people won't

Posted: **Wed Mar 17, 2021 4:39 pm**

I'm doing my part![img]https://uploads.tapatalk-cdn.com/202103 ... 7215d0.jpg[/img]

Edit: Ah crap, it should be animated...

Posted: **Wed Mar 17, 2021 5:04 pm**

ProcedureASM() was one of my feature requests it would be really cool if its still an option once/if inline is back.

I'm not 'walking on clouds' like some other people here but I'm certainly looking forward to each new update..
But user_Russian is correct - it is time to make another donation. Not because of future updates but because it is time. [donation made].

Stay strong and creative Fred & team!

I actually like this way, very clever.
