This was a tip by cas!

Fred!
It's very cool news!!!
My very very big thanks for new compiler!

With this new PureBasic i can delete my C compiler!

Thank you very much, Fred and team! In my big projects only the following constructs stopped working with the C backend:

Code: Select all

ExtractJSONStructure(JSONValue(File), @Items\ServiceProviders(), ServiceProviderItem)

gives

Code: Select all

purebasic.c:7121:19: error: expected expression before 's_serviceprovideritem'
 void* p672=(void*)s_serviceprovideritem;
                   ^~~~~~~~~~~~~~~~~~~~~

and

Code: Select all

End SendNotifyMessage_(#HWND_BROADCAST, Temp\Application, 0, #MessageWindow)

gives

Code: Select all

purebasic.c:8059:1: error: 'PB_ExitCode' undeclared (first use in this function); did you mean 'PB_ErrorCode'?
 PB_ExitCode=65535;
 ^~~~~~~~~~~
 PB_ErrorCode

Unfortunately I am unable to reproduce these errors with smaller code snippets outside of my projects context.

Please report bugs in Bug C-backEnd. PB_ExitCode has already been reported.

It would be nice if PureBasic 6.00 also modernized the IDE and help theme,
following for example the one you put for SpiderBasic.
(The same colors for the code on this forum would also be a plus.)

For possible new customers, the current PB IDE and Help theme: yellow background and Courier font reminds too much of old Windows 95 programs, or even Windows 3.x.

I disagree!
No need to modernized. Let it be as it is now.

I agree 100%. Let the IDE as it is.

I agree 100% with Marc56, Like what, tastes and colors

I personally find the default theme really bland and retro for a modern language. But with the benefit of being restful for eyes.
It would be good to modernize the default theme in my opinion and to follow the Windows's theme evolutions with an entire team dedicated to ergonomics.

I sent a private e-mail to Fred weeks ago and no reply

So I will make it public:

Will 6.0 use fast strings?

Strings are currently very slow because in every access to them PB scans until it reaches the end.

The idea would be to have the size of each string stored in a 32-bit number (up to 4 GB strings) and it would only seek for the end if all the 32-bits were set to 1 (meaning that the string could be over 4 GB).

I know this will consume more RAM but it could be in a setting for users to turn it on/off.

This is an idea worth checking for.

Thank you very much!

Also, change V6.0 licence to a yearly subscription so that you can get more money for development.

EDIT:
Also add a two-pass compiler to optimise the code, such as:
x+10+5+5
would become compiled as:
x+20

That would be automatically handled by the gcc C compiler.
That's one of the real beauties of the new C backend - so many optimisations from one of the smartest compilers on the planet

If you're curious about all the optimisations that our source code will now be subject to with the new C backend, thanks to one of the best optimising compilers in the world - GCC - please check out this wikipedia page: https://en.wikipedia.org/wiki/Optimizing_compiler
This also FREES Fred from having to focus on optimisation, now that a state-of-the-art compiler takes care of that, enabling Fred to focus on things like bugfixes and new features.
It was a very brave move for Fred to move to the C backend, but I can only see it as an absolute winner

A POWERFUL upgrade.

@Keya

Will it also use "fast strings" out of the box for ultra speed?

Thanks!

I would guess no, because C uses null-terminated "C strings" - the same as Purebasic has always used.
There have been examples posted though of "fast strings" (eg storing the length before the string), but I'd be surprised if it became native

Hi,

I would like to ask for a new Alpha 2 version, as there are now so many [Done] Bugs.

Greets, hoerbie
