Hi folks,

Here is the new 3.30 beta version of SpiderBasic introducing a nice new feature we wanted to implement since a while: async/await support. What does it means for you ? Less callbacks ! The commands can finally wait for there execution to finish and you can code in a more linear fashion.

For example, using the OpenFileRequester() to display a local image was looking like that:

Code:

Procedure Loaded(Type, Filename$, ObjectId)
  Static x = 200, y = 200
 
  OpenWindow(#PB_Any, x, y, 300, 300, Filename$, #PB_Window_TitleBar | #PB_Window_SizeGadget)
    ImageGadget(#PB_Any, 0, 0, ImageWidth(ObjectId), ImageHeight(ObjectId), ImageID(ObjectId))
 
  ; Shift the next opened window
  ;
  x + 40 
  y + 40
EndProcedure
 
 
Procedure LoadingError(Type, Filename$)
  Debug Filename$ + ": loading error"
EndProcedure
 
 
Procedure RequesterSuccess()
 
  ; Process all the selected filename
  ;
  While NextSelectedFile()
    LoadImage(#PB_Any, SelectedFileID(), #PB_LocalFile) ; when using #PB_LocalFile, all files selected with OpenFileRequester() are directly available
    Filename$ = SelectedFileName()
  Wend
 
EndProcedure
 
Procedure ButtonEvent()
  OpenFileRequester("image/*", @RequesterSuccess(), #PB_Requester_MultiSelection)
EndProcedure
 
 
OpenWindow(0, 100, 100, 200, 45, "Image viewer", #PB_Window_TitleBar)
ButtonGadget(0, 10, 10, 180, 25, "Open local image...")
BindGadgetEvent(0, @ButtonEvent())
 
; Register the loading event before calling any resource load command
BindEvent(#PB_Event_Loading, @Loaded())
BindEvent(#PB_Event_LoadingError, @LoadingError())

Now, the same code using async under the loop makes the code easier to follow and more PureBasic-like

Procedure ButtonEvent()
  x = 200
  y = 200
 
  Filename$ = OpenFileRequester("image/*", #PB_Requester_MultiSelection)
 
  ; Process all the selected filename
  ;
  While Filename$
    Image = LoadImage(#PB_Any, Filename$, #PB_LocalFile) ; when using #PB_LocalFile, all files selected with OpenFileRequester() are directly available
    If Image
 
      OpenWindow(#PB_Any, x, y, 300, 300, Filename$, #PB_Window_TitleBar | #PB_Window_SizeGadget)
        ImageGadget(#PB_Any, 0, 0, ImageWidth(Image), ImageHeight(Image), ImageID(Image))
 
      ; Shift the next opened window
      ;
      x + 40 
      y + 40
    EndIf
 
    Filename$ = NextSelectedFilename()
  Wend
EndProcedure
 
OpenWindow(0, 100, 100, 200, 45, "Image viewer", #PB_Window_TitleBar)
ButtonGadget(0, 10, 10, 180, 25, "Open local images...")
BindGadgetEvent(0, @ButtonEvent())

This is early work on this and if it works well it be done for the whole commandset. I tested on cordova and it works as expected, but feel free to test and see if it is OK.

The modified affected commands which now uses await:

CaptureImage()
CloseFile()
CopyFile()
CreateDirectory()
DeleteDirectory()
DeleteFile()
ExamineDirectory()
FetchData()
FileSize()
GetFileAttributes()
GetFileDate()
HTTPRequest()
LoadImage()
LoadJSON()
LoadScript()
LoadSound()
LoadSprite()
LoadXML()
OpenFileRequester()
ReadFile()
RequestFileSystem()
SetCurrentDirectory()

That means that these commands doesn't need a callback anymore and will returns the result directly when the processing is done, actually blocking the program flow.

Here is the change list for this version:

Added: async/await support for most of the commands, callbacks are now optionals and program flow easier to follow !
Added: FileSystem library to easily act on local files (iOS, Android only)
Added: Preference library using local storage based on Peter's work (Thanks ! https://github.com/spiderbytes/Preferences)
Added: CaptureImage() to get an image from the camera (iOS, Android only)
Added: CreatePasswordHash() and VerifyPasswordHash() based on bcrypt
Optimized: Splitted the system library to not have all cordova libs included when using a single command
Optimized: Android app creation should be much faster on Windows
Changed: NextSelectedFile() to NextSelectedFileName()
Removed SelectedFileName() and SelectedFileID()

Have fun !
