Inspired by this new feature introduced in PB5.40b3 I thought a similar new "intuitive" option that automatically reads/writes the default string format would be handy.
Example for
ReadFile() (or
OpenFile()):
Code: Select all
; Normal way:
If ReadFile(0, File)
Format = ReadStringFormat(0)
String = ReadString(0, Format)
EndIf
; More intuitive:
If ReadFile(0, File, #PB_File_AutoStringFormat)
String = ReadString(0)
EndIf
Example for
CreateFile():
Code: Select all
; Old way:
Format = #PB_UTF8
If CreateFile(0, File)
WriteStringFormat(0, Format)
WriteStringN(0, String, Format)
EndIf
; New way (PB5.40b3):
Format = #PB_UTF8
If CreateFile(0, File, Format)
WriteStringFormat(0, Format)
WriteStringN(0, String)
EndIf
; Even better:
If CreateFile(0, File, #PB_UTF8 | #PB_File_AutoStringFormat)
WriteStringN(0, String)
EndIf
Edit:
#PB_File_AutoStringFormat isn't official. It's my proposal for a new flag.

What is, when you use #PB_UTF8 without a BOM? WriteStringFormat is only to write a BOM,
so a automated BOM is not always recommend. Or i understand it false?

The shown "new way" for CreateFile() is already implemented. So if you don't want the string format to be automatically written you simply wouldn't use the proposed #PB_File_AutoStringFormat flag.

Code: Select all
Result = CreateFile(#File, Filename$ [, Flags])
A new flag was added (
#PB_File_AutoStringFormat ) to the
CreateFile(#file,filename$,#PB_File_AutoStringFormat)? How about
CreateFile(#File, Filename$,#PB_Ascii or #PB_UTF8 or #PB_Unicode) ? If you use the
#PB_File_AutoStringFormat flag (or either of the other three flags) do you need to write the
WriteStringFormat()? And I'm assuming that the
WriteStringFormat() is automatically added if the saving is in the default unicode compiler mode?
I'm finding that it doesn't seem to matter if the file being read is in ascii if I'm in the unicode mode. (It DOES matter if I try to read a unicode file in ascii mode).
Right now I'm checking the
bom=ReadStringFormat() then reading using
ReadString(#File,bom).
Maybe I'm over-thinking this...

I'm not sure if you're confusing something here...
#PB_File_AutoStringFormat is not official, it's my proposal. And no,
Read/WriteStringFormat() isn't used automatically (e.g. see Fred's reply
here). Again, that's what this feature request is for.

Here Fred seems to be saying he has made a change and that was what I was asking about but it is not explained in 'Help'.
