PureBasic 5.50 final is out !

Post by Fred »

Hi there,

- Final version is out, thank you all for feedback and testing !

- Beta 3 is out and brings some more fixes.

- Beta 2 is out ! It does includes a bunch of fixes and updated SQLite lib to 3.13.0.

PureBasic 5.50 is now available as beta in your online account ! The most important change is the unicode only compiler. To sum-up, internal string representation are now always in unicode, and if you need to interact with third part libraries, the suggested approach is to use pseudotypes (p-ascii, p-utf8) combined with Import/EndImport or Prototypes. 2 new helpers functions have been added as well to created easily an ASCII or UTF8 buffer from a string: Ascii() and UTF8(). If your program was already compiled with the unicode switch, then nothing will changed for you (if it does, then there is a bug somewhere, don't hesitate to report it). Here is the full list of features:

Code: Select all

- Added: Vehicle library to create 3D vehicles with wheels easily
- Added: PickBody() to easily manipulate a 3D body with mouse
- Added: CreateTube(), CreateTorus(), CreateIcoSphere() and CreateCapsule()
- Added: #PB_Entity_PlaneBody and #PB_Entity_ConeBody body type
- Added: GenericJoint() to create any type of joint
- Added: Bounding box size support to CreateEntityBody()
- Added: RegisterFontFile() to use custom fonts file easily
- Added: PathLength(), PathPointX(), PathPointY(), PathPointAngle()
- Added: PathBoundsX(), PathBoundsY(), PathBoundsWidth(), PathBoundsHeight() to get the bounding box of a path
- Added: PathSegments(), AddPathSegments() to get/set a path in string format 
- Added: DebuggerError(), DebuggerWarning(), CloseDebugOutput()
- Added: ResetStructure() which clear and reinitialize a structure buffer
- Added: UTF8() and Ascii() to create easily UTF8 and Ascii string buffers (needs to be freed with FreeMemory())
- Added: FormatNumber() to have money like formatted numbers easily
- Added: @#StringConstant$ syntax support, to get the address of a string constant
- Added: #PB_MessageRequester_Info, #PB_MessageRequester_Error and #PB_MessageRequester_Warning for MessageRequester()

- Changed: ParticleVelocity() to support current velocity.

- Removed: ASCII mode for internal PureBasic string representation, PureBasic is now unicode only.
As every beta, only the english doc is up to date for now, so be sure to use it if you want to have more info about new commands.

Have fun !

Thank's Fred 8)

My tests:

- Forgot the classic "?" (question-mark) icon constant for MessageRequester() (#MB_ICONQUESTION)

- In Form Designer, for DateGadget() parameter Date() is not set so CheckBox and up/down button spin do not appear if selected (old bug)

- In help file, for DebuggerWarning(), forgot to specify "The program execution will be stopped if the debugger is activated" (like DebuggerError() description)

I does not use graphics (for the moment) So I have not tested the rest.

Thank' s for FormatNumber() Excellent feature for business users :!: :wink:

DebuggerWarning() doesn't stop the program execution, it's just a warning. You should use the appropriate bug forum to report your issue or it will get lost :)

Thanks (adieu ascii builds, I hope you died for something good in exchange).

Is there hope for these two to be fixed before the final ?

Thanks Fred for this new release.

First test:
-GetFunctionEntry() no longer works
Example GetFunctionEntry(fmodLib, "FMOD_Memory_Initialize") with PB 5.42 Works with PB 5.50 not works.

➽ Windows 10 - PB 5.73(x64)

Well now I must dive deeper into the use of unicode.
I only understand it uses 2 bytes instead of one, but as I always could simply avoid the use of unicode (never 'been forced' or feld the need to using it). I worked on that way.
Now that I need to do this step, I hope the water isn't that deep (I use a lot of text file in ascii ... as far as I'm even abale to see the difference).
If anyone has fine tips to make the learning curve easier, it's welcome.

Thanks Fred and the pb-team for your work.
Yeah I know, but keep in mind ... Leonardo da Vinci was also an autodidact.

Any reason you didn't include all new Vector library commands ?

As I expected, it did not work.

Code: Select all

ProcedureDLL Tst(x.p-ascii)
  
EndProcedure
The lack of support for ASCII, can complicate the DLL development, because not all applications support unicode. And if with string parameters procedures, can be solved so.

Code: Select all

ProcedureDLL Tst(*x)
  s.s = PeekS(*x, -1, #PB_Ascii)
EndProcedure
But with structures much more complicated.

Code: Select all

Structure Param
  Str1.s
  Str2.s
  Str3.s
  Str4.s
  ; Many other string variables
EndStructure

ProcedureDLL Tst(*x.Param)
  s.Param
  s\Str1 = PeekS(@*x\Str1, -1, #PB_Ascii)
  s\Str2 = PeekS(@*x\Str2, -1, #PB_Ascii)
  s\Str3 = PeekS(@*x\Str3, -1, #PB_Ascii)
  s\Str4 = PeekS(@*x\Str4, -1, #PB_Ascii)
  ; Converting other variables structure
EndProcedure
The PB no function which converts the encoding of string variables in structures.
I propose to add the function ConversionStructure. Syntax:

Code: Select all

*Item.StructureName = ConversionStructure(*Source, Structure, SourceFormat [, DestinationFormat])
Parameters *Item.StructureName, *Source and Structure are the same as in the function AllocateStructure.
Parameters SourceFormat and DestinationFormat are the same as in the function PeekS.
If the parameter DestinationFormat is not specified, then the structure is converted to unicode.

It is also necessary to add to the function FreeStructure optional parameter Format. Syntax:

Code: Select all

FreeStructure(*Item [, Format])
If the parameter Format is not specified, it is assumed that this is a unicode structure.

Example 1. The application transmits the DLL structure with ASCII strings.

Code: Select all

Structure Param
  Str1.s
  Str2.s
  Str3.s
  Str4.s
  ; Many other string variables
EndStructure

ProcedureDLL Tst(*x.Param)
  
  *s.Param = ConversionStructure(*x, Param, #PB_Ascii) ; Converting structure from ASCII to Unicode.
  
  FreeStructure(*s) 
EndProcedure
Example 2. DLL returns an ASCII structure for the application.

Code: Select all

Structure Param
  Str1.s
  Str2.s
  Str3.s
  Str4.s
  ; Many other string variables
EndStructure


ProcedureDLL Tst()
  s.Param
  
  s\Str1 = "Data"
  
  *ret.Param = ConversionStructure(@x, Param, #PB_Unicode, #PB_Ascii) ; Converting structure from Unicode to ASCII.
  
  ProcedureReturn *ret
EndProcedure

ProcedureDLL FreeStruct(*x.Param) ; The application must call this procedure to release structure.
  If *x
    FreeStructure(*x, #PB_Ascii)
  EndIf
EndProcedure

Thank you Fred! I didn't realize you had the ability to read minds! UTF8 (), Ascii (), FormatNumber (), and especially @#StringConstant$() & RegisterFont () are going to be extremely useful for me. I can
use them all in my most recent project I am starting today.

Code: Select all

- Added: DebuggerError(), DebuggerWarning(), CloseDebugOutput()
- Added: ResetStructure() which clear and reinitialize a structure buffer
- Added: @#StringConstant$ syntax support, to get the address of a string constant
These 3 looking nice and useful ^^
