Hi,

I'm using Lazarus 1.5 r47664 FPC 2.6.4 x86_64-linux-gtk 2

I looked at the following documentation regarding "repeat count"

http://wiki.lazarus.freepascal.org/IDE_Window:_Watch_list#Watch_Properties

In the wiki it says "Repeat Count" was implemented in Lazarus 1.1 already (see the bottom of the section in the wiki), but I can't seem to get it to work in Lazarus 1.5. I only ever see the first element specified. eg: b[10] and then a repeat count of 5, but I only see b[10]'s value.

I tried using both GDB and fpDebug debuggers.

Is this actually implemented, or am I using it wrong?

Regards,

how is b defined?

IIRC (need to check) repeat count cuts off at the boundaries of an array b: array [3..10] of integer
will never show b[11].

But ^integer(@b[10])[0] will show it

Also, if you use the "detail pane" in watches. This had a bug, that was fixed only recently. But the "value column" should be fine.

Otherwise can you get a lof:

=====================================
program project1;
uses
  SysUtils;
var
  a: array[0..999] of integer;
  b: array[0..100] of string;
  i: integer;
begin
  writeln('Let''s start');
  for i := 0 to 999 do
    a[i] := i;
//  writeln('a[0] = ', a[0]);
  for i := 0 to 99 do
    b[i] := 'str' + IntToStr(i);
  writeln('b[0] = ', b[0]);   //  <-- Breakpoint is set here
  writeln('That''s all folks!');
end.

No, the repeat count would have been well within the bounds of the array.

No, didn't even know there was "detail pane". :)

I was just evaluating the latest debugging features in Lazarus IDE, and comparing GDB and fpDebug output.

I also wanted to see if Lazarus IDE had something like Haiku's Debugger has - Array Ranges. If it didn't (Repeat Count seems close), I thought I might take a shot at implementing it. It doesn't seem too hard to accomplish [please correct me if I am wrong].

I tried this program, with {$H+} and {$H-}

In both cases I got 5 strings (for a repeat count of 5) http://i.imgur.com/ZSNsTzd.png

So I need a logfile please, to see why it does not work for you. http://wiki.lazarus.freepascal.org/GDB_Debugger_Tips#Log_info_for_debug_session

Just a note. This only works if you leave the watch type on "default"

Ah, that solved it! I set it to String because I knew the array was of string type.

Thanks for helping find the solution.

Yes that needs improving. But its not high priority now.
