Hide comments from Object Inspector
lazarus / 9-Editor

Acording to this doc [http://wiki.freepascal.org/Lazarus_IDE_Tools#Com
ments_shown_in_the_hint]

QuoteComments starting with $ and % are ignored.but this is not true
only comments starting with
a) Quote(*$  this is a hidden comment )
and  b) Quote{$  are ignored.
The above results are for a) this error  QuoteWarning: Illegal
compiler switch "$" 
and for b) the comments are red!!
Is there another way to hide comments from Object inspector?
if there is no  other way is it safe to useQuote(*$  this is a hidden
comment )  ??

Edit**:Fixed Post thanks @Mike.Cornflake

You're good at finding the obscure stuff that I've never noticed
before :-)   I'm away from Lazarus at the moment, but I'll look at
this tonight...

The $ bit is not about hiding about comments from the Object Inspector
as such, so the wiki is a little misleading.  The exclusion code would
have been put in because {$ is special.  It's for compiler directives,
not for comments, so that error message you're getting is perfectly
valid.

Code: [Select]{$IFDEF WIN32}
  CallWIN32Code;
{$ELSE}
  MakeADifferentCall;
{$ENDIF}
I don't know about the % stuff, and it's that that I'll look at
tonight...

By the way, your post was really hard to read.   Can you please
investigate and start using the [ code ] tags?  The example I posted
above is written as

[ code ]{$IFDEF WIN32}
  CallWIN32Code;
{$ELSE}
  MakeADifferentCall;
{$ENDIF}[ /code ]

Just with the spaces inside the [ ] removed...

I can confirm your results about code hint visibility on Lazarus 1.3

I've already covered the {$DEFINE} scenario, which is a special case
(and this is why it's shown in red - to emphasize that it's special). 
The only comment I could get to hide was (*$ This is successfully
hidden *), all others were shown

I suspect the code is working as expected, and that the wiki just
needs to be updated.  I'll post a query on the mailing lists and get
back to you...

Code: [Select]procedure TForm1.Button1Click(Sender: TObject);
Var
  sHint1: String; { This hint is shown }
  sHint2: String; {% This hint is shown }
  sHint3: String; (*$ This is successfully hidden *)
  sHint4: String; (*% This hint is shown *)
  sHint5: String; //$ This hint is shown
  sHint6: String; //% This hint is shown

  { This hint is shown }
  sHint7: String;

  {% This hint is shown }
  sHint8: String;

  (*$ This is successfully hidden *)
  sHint9: String;

  (*% This hint is shown *)
  sHint10: String;

  //$ This hint is shown
  sHint11: String;

  //% This hint is shown
  sHint12: String;
begin
  sHint1 := sHint2 + sHint3 + sHint4 + sHint5 + sHint6;
  sHint7 := sHint8 + sHint9 + sHint10 + sHint11 + sHint12;
end;

Again, nicely found @Never.

I reported this on the mailing list, and most of the forms were
immediately fixed in Trunk.  The last remaining form (*% This hint is
shown *) is also apparently fixed, but I'm away from Lazarus until
this evening so cannot confirm.

If you want to play with Trunk for yourself to confirm, well I
recommend fpcup :-)

If you have any issues with fpc, search this forum or read the wiki
first.  Lots of questions have already been answered.  But generally,
it just works out of the box.
