[fpc-pascal] Re: Mattias Gaertner: regexpr

[L505]

Knock knock, is anyone home on Sunday in Netherlands and elsewhere? The list is quiet... ;-)

Well, I looked through the Lazarus sources and Synedit sources, because I remember the fact that synedit had
it's own semi modified version of Regexpr Studio's Tregexpr. And hey, if Lazarus runs on GnuLinux, and it uses
Synedit, how is it using regular expressions?? It  must be using them.. sooooo.....Of course, I went in and
found that synregexpr unit. Then I just commented out some of the IfDef's for syn_Lazarus and renamed the unit
to "Regexpr2.pas".

Compiler eats up the Regexpr2 I made with no troubles. So now I can use regular expressions in freepascal
without problems, for generic uses (not just for synedit!).

I think we should put this unit up in the contributed units section on the FreePascal.org website. I'll put it
on my FTP too, because I'm sure others are looking for a working regular expression unit with back references.
Hopefully I can also notify the owner of RegexprStudio website to put the Regexpr2.pas unit I made, because
his website only offers a freepascal regexpr unit that works on Win32 right now.

Of course we always have the other regexpr unit by Florian to work on also.. since it's not completed yet.

Example simple regular expression program working in Linux

Program ExampleRegexpr;

Uses
 Regexpr2;

{
Program to demonstrate the secondary Regular expression unit
  Note: not the one by Florian, but the RegexprStudio.
}

const
 InputStr : PChar = 'This is a simple string.';
var
      TestRgx:tregexpr;
begin
   testrgx:=tregexpr.create;
   testrgx.expression:='i(.*)P';
   testrgx.exec(InputStr);
   writeln('The main match: ' + testrgx.Match[0]);
   writeln('The first back reference match: ' + testrgx.Match[1]);
   If testrgx <> nil then
   begin
    testrgx.free; //should have used FreeAndNil!
    testrgx.nil;
   end;
   readln;

end.

| Do you  know which unit this is that you talked about of above? I'm looking for regexpr units and I wondered

unit
