[Gambas-user] trimming extra spaces from within a string.

[Brian G]

Fabian, for fun I adjusted your algorithm to use pointers not string
to try the fast unsafe with it.

Its made it 9 times slower than with a string.... wow unexpected!

like this
OutBuf As Pointer = Alloc(1000000)
Fast Unsafe Public Sub FabienTrim(sRaw As String) As String

  Dim s As String
  Dim hStream As File
  Dim bFirst As Boolean = True
  hStream = Open Memory Outbuf For Write
  ' 
  For i As Integer = 0 To Len(sRaw) - 1
    s = sRaw[i]
    If s = " " Then
      If Not bFirst Then
        Write #hStream, s
        bFirst = True
      Endif
    Else
      bFirst = False
      Write #hStream, s
    Endif
  Next
  
  Print "do close"
  Write #hstream, 0 As Byte
  Close #hStream
  s = String@(OutBuf)
  If bFirst Then Return Left(s, -1)
  Return s

End

Thank You

Fabian it looks like a bug in the fast functions, interpreted for strings as streams. Is it worth reporting it as a bug?

Thank You

I agree !! :-)
