Hi, All!

Simple question)

In FileUtil unit placed useful functions for processing file names.

Why I can not use them in ConsoleApplication?
Is it possible make those useful functions more usable in other
programming environments, except GUI?

Found this:
http://www.freepascal.org/docs-html/rtl/sysutils/filenameroutines.html

So - why duplication? SysUtils vs FileUtil.

Such duplication is usually because Lazarus regards ansistrings as
UTF8, while FPC regards them as having the native encoding (whatever
that is)

would be extensions to SysUtils, such as ExtractFileNameOnly and
FileSize function.

General functions should be propagated back. We also do this with
Windows headers, where Lazarus has its own cache of headers (unit
win32extra or so) that is from time to time absorbed into the general
windows headers.

Now is a good moment to flag content for migration back to FPC, with a
major version coming up this summer or fall, but still early enough to
merge a bunch of procedures.

Today I was fighting with a bug in Mac version of my application, it
receives via web some absolute path from Win32 version of my
application and use ExtractFileNameOnly(); to extract file name. And
here is the bug.

ExtractFileNameOnly do a while cycle over chars in FileName and seek
until ':' or PathDelim is found, but on Mac (unix in general)
PathDelim is / and in Windows is \ so ExtractFileNameOnly gives me the
exact same Win FileName only with cutted extension...

I'v made my own function which is equal to fileutil.inc except for
line 640:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i     and not
(Char(AFilename[StartPos-1]) in AllowDirectorySeparators)    {$IFDEF
Windows}    and (AFilename[StartPos-1]<>PathSep){$ENDIF}(with another
fix, PathSep instead of ':')

Do you think this one is correct or it can produce some unpredictable
output with backward compatibility?
