Regular expressions are used by vi and emacs; in fact, any editor that doesn't let you do a regex search is a joke. (Even some microsoft applications understand regexes.) So everyone who programs should learn regular expressions. Regular expressions are also used by grep, and by the languages awk, Ruby, Perl, etc. Every programmer should know how to use at least one of these languages. Those who don't should perhaps be lumped together with COBOL programmers. Therefore, I honestly believe that anyone who doesn't understand regular expressions has a huge, glaring, inexcusable hole in his computer knowledge. Ignorance of regular expressions is like not knowing how to tie one's shoelaces: it's not something to boast about. The fact that a single regular expression takes as much time to read and understand as many lines of Pascal isn't a problem, because the regex does as much work as many lines of Pascal. Don't worry about that; you'll spend more time writing them than reading them. Regular expressions are no more against the spirit of Pascal than associative arrays (hash tables) or any other feature that is added by using a unit. __ Do You Yahoo!? Tired of spam? Yahoo!

[fpc-pascal] regex-dna: finally fast enough?
I don't think so, although it's over twice as fast as the
last incarnation.
One speedup I stole from the Perl program:
instead of counting matches for /foo|bar/, count matches
for /foo/ and for /bar/.
The other speedup is lowercasing the string that is searched
instead of requiring the regex engine to do a case-insensitive
search.
I don't think this should be submitted to the shootout site
unless it will improve Free Pascal's standing; i.e., unless
it is not more than 1.4 times as slow as the Perl program.

Ummm, but there is nothing else on that function, so I don't see how
can the temporary string be destroyed before I call SETTEXT, unless
SETTEXT expects that I give it a storage that is at all times
available...
procedure TWin32MemoStrings.SetText(TheText: PChar);
begin
SendMessage(fHandle, WM_SETTEXT, 0, LPARAM(TheText));
end;
Which I currently converted into (but still doesn't work):
procedure TWin32MemoStrings.SetText(TheText: PChar);
var
AnsiBuffer: ansistring;
WideBuffer: widestring;
begin
{$ifdef WindowsUnicodeSupport}
if UnicodeEnabledOS then
begin
WideBuffer := Utf8Decode(TheText);
SendMessage(fHandle, WM_SETTEXT, 0, LPARAM(PWideChar(WideBuffer)));
end
else
begin
AnsiBuffer := Utf8ToAnsi(TheText);
SendMessage(fHandle, WM_SETTEXT, 0, LPARAM(PChar(AnsiBuffer)));
end;
{$else}
SendMessage(fHandle, WM_SETTEXT, 0, LPARAM(TheText));
{$endif}
end;
Alternatively I moved AnsiBuffer and WideBuffer to the class
declaration, so they are always available, which also didn't solve the
problem of showing wrong characters.
It shows the string ééé as if it was Ã(c)Ã(c)Ã(c)
Which is what I would expect if I use ansi routines to show a utf-8 string.

Hello, I still have some issues with unicode support =) I am trying to implement unicode support for TMemo, but somehow the solution isn't simple. TMemo will throw a WM_SETTEXT message to when it's text is set, like this: SendMessage(fHandle, WM_SETTEXT, 0, LPARAM(TheText)); Which I tryed to convert to: if UnicodeEnabledOS then SendMessage(fHandle, WM_SETTEXT, 0, LPARAM(PWideChar(Utf8Decode(TheText else SendMessage(fHandle, WM_SETTEXT, 0, LPARAM(PChar(Utf8ToAnsi(TheText; But this doesn't seam to work, and the text is shown scrambled. I would think that the control wasn't create with unicode functions, but this is impossible because handle creating is centralized and all other controls work normally, setting the same text to them. I already debugged and execution flow does go throught that part. There is just something about using WM_SETTEXT to set the text of a control which escapes me.
