Sorting output of Dir()

[Xusinboy Bekchanov]

So you are saying that on UEZ's computer, literal strings like "abc" become wstr("abc") after a var, which is not allowed for var.

Not only in UEZ's computer, this happens in all computers if you save a file in Unicode format (UTF8 (BOM), UTF16 (BOM), UTF32 (BOM), ...).

Thank you Xusinboy Bekchanov for clarifying this issue.

I need to remember this for the future, that if the code is stored in UTF format, I use Str() or use text format to avoid problems and don't waste time in troubleshooting.

On the contrary, I need a unicode string and always include #define UNICODE before #include once "windows.bi". In my case, the Str function is not needed, because all WinAPI functions require WString string.

But not accepting var s="abc" say should not make "abc" wstr("abc") on some computers, it is surely a bug in this case.

Code: Select all

Var s1 = "FreeBASIC"        '' ok
Var s2 = Str("FreeBASIC")   '' ok
Var s3 = Wstr("FreeBASIC")  '' error 24: Invalid data types in 'Var s3 = Wstr("FreeBASIC")'

At the moment, the compiler has String (a dynamically resizing ANSI string) for ZString, but there is no UnicodeString or UString for WString yet, if this is added, then Var s = "қандай - what" will also be possible.

You didn't check, I think, the example Var s1 = "FreeBASIC" with the UTF8 (BOM) file format.

Yes.

Code: Select all

#print typeof("literal string") 

I get
ZSTRING * 15
Shouldn't all computers get this message (i.e. a zstring) in the comiler message window?

If you make the source file format ANSI then: ZSTRING * 15
If you make the source file format UTF8 (BOM) then: WSTRING * 15

I added a bom, should be wstring now for literal strings under var, with the compile error at line 3 accordingly.
Thanks for explaining - everybody.

Code: Select all



var k="hi"
print k
 #print typeof("literal string")
 Sleep
sleep

Maybe your IDE does not support UTF8 (BOM), try compiling using command line.

[dodicat]

By adding the BOM to the .bas file, as I have done, the file is UTF8 (BOM).
I can compile via command line or fbide (my choice of ide), and a literal string will be a wstring * (some size).
Thus It will error on var s="some string".
So as UEZ says, there is a bug, (an inconsistency under var).
Or maybe you get a different compile error?
I get
FBIDETEMP.bas(3) error 24: Invalid data types

[fxm]

This is not a bug but rather a deficiency well-specified in the documentation:

Note: Wstring is not supported with Var, due to the fact that there is no var-len Wstring type. This isn't likely to change, due to the complexities involved with handling Unicode.

Otherwise this below compiles:

Code: Select all



var k=Str("hi")
print k
 #print typeof("literal string")
sleep

Code: Select all

hi

Code: Select all

WSTRING * 15

[dodicat]

I think that you still might use fbide fxm, with the console open (you don't usually sleep at the end)

What does UEZ use these days, to automatically load .bas files as a utf-8 with BOM?
I think that automatically making all literal strings wstring might produce some more strange results. Who knows?
