Yes, I tried to achive it with macros, without success.

I'm surprise for your question, because I started been interested in  
language/compiler design because I wanted a preprocessor for Turbo  
Pascal,
like Turbo C++ ;-)

Let me understand, you already have the preprocessor to transform your  
"Pascal with Tags" into a "Pascal without tags" source code file ?

Something like:

-------------

program PreprocessorExample;

#define Pi 5

begin
   Write('Pi value is ', Pi);
end.

-------------

Into something like :

-------------

Ah, yes, I remember. My first thought was to replace fpc with a batch
file, but I didn't try.

So, as I wrote, if the preprocessing is located in the compiler it

Doesn´t need to be a batch file. Can be an executable. And you can
change the path to fpc executable on Lazarus IDE to point to your
bat/exe, so you don´t have to really replace fpc.

This could be a easy solution.

your preprocessor could check if the file being compiled has .tpp
extension, and if so preprocess it and send to fpc. If not, send
directly to fpc.

No changes necessary on fpc or lazarus =)

Taction and TTranslateString (String properties)

Hi all, 

i played arround with some Run-Time Translation of Conmpnents, because I
want to have such a feature in my apps. 
I found, that you have done some work on such things. the TCaption
properties can be scannde by using RTTI, very nice Smile. 
But I as I tried to use this functionality on TActionLists, I found,
that the Caption and Hint Properties of TContainedAction are of type
String. 
As I added some Lines in the ActionList unit: 

                                 Code:

                                 type 

                     TTranslateString = type String; 
                      TCaption = TTranslateString; 

To Avoid Circular references by with the Controls unit. 
After That i changed the String Properties of TContainded action to
TCaption. 
Now everything is fine for me. 

Now my questions: 
1. Is there a reason why this String-Properties aren't replaced ? 
2. Could my modification or some similar solution added to the units to
have the TTranslateString - Feature in Actions ? 

Thanks for all the work everyone has done here, great job 
:)

Re: TTabControl and OnChange event

Ok, I found a work-around for now - though not ideal!  I have to get
the ComponentState as the first thing, so that when I destroy the
form, the 'other stuff' doesn't get executed.

procedure TLearnerListForm.IndexTabControlChange(Sender: TObject);
begin
  if csDestroying in ComponentState then
    exit; //==>
  <.... do other stuff...>
end;

Regards,
  - Graeme -

The page I found it mentioned was one that was speaking of Visual
Development on Linux (compared to VB on Windows) and didn't mention Lazarus
at all (only some replies to that topic mentioned it, but they forgot to
post a URL). From the image they had there about Gambas it looked more
appealing than Lazarus (for example when you launch Lazarus [if you don't
tell it to open something], is there option to autostart with the File/New
dialog? [that should be the default option and have checkbox to not show
that at start again]).

What I mean is that Pascal is almost as easy as Basic to use (apart from
VB's With and Case which are better in my opinion, or ForEach which is
missing), and isn't case-sensitive as C/C++/Java/C#/etc. and is
natural-language friendly (not have to learn some strange symbols and how to
put them together to author a program as in some well-known scripting
languages), so it's either that Lazarus is missing some IDE touches to make
it more appealing to newcomers, or that it needs more/better PR (e.g. try to
post nice screenshots of it to such net discussions that newbies [esp.
interested in university students] may come across while searching for what
IDE to use)

RE: Gambas

So you say its all about marketing?
I run a opensource Accounting project and I have the same problem try to
attract as manny new user as you can meens you need to market it for
that user group. I gess writing to all universities we can get a email
adres from is a start but calling someone in your local area is probably
the most effective. On call to the right person can set things in
motion. I think Lazarus is the best choice for students. But we will
need to reache the tutors for that to happen so they can point to the
right directions (the Lazarus site :-).

I tried it. Don't waste your time, we are way ahead...
