Is there a bug regarding the colouring of the texts?
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i program
Project1;{$if declared(xisntthisabugx)}const  xisthisabugx = 'xx';
//black line, should have been grey{$endif} {$if
declared(isntthisabug)}const  isthisabug = 'yes'; //black line, should
have been grey{$else}const  isthisabug = 'no'; //grey line, should
have been black{$endif}beginwriteln(isthisabug); //writes
no//Obviously, the following line fails to
compile//writeln(xisthisabugx);end.

Maybe this will explain how the things work:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i program
Project1;//{$if declared(xisntthisabugx)}{$ifdef xisntthisabugx}const 
xisthisabugx = 'xx'; //black line, should have been grey - NOW IT IS
GREY{$endif} //{$if declared(isntthisabug)}{$ifdef isntthisabug}const 
isthisabug = 'yes'; //black line, should have been grey - NOW IT IS
GREY{$else}const  isthisabug = 'no'; //grey line, should have been
black - NOW IT IS BLACK{$endif}beginwriteln(isthisabug); //writes no,
 AND IT IS OKreadln;//Obviously, the following line fails to
compile//writeln(xisthisabugx);end.  
Added:
Good thing is that if Lazarus can properly parse {$IFDEF XXX} clauses
- there is a very short way to do the same with
{$IF DECLARED(XXX)}.

Note, code explorer displays at "Directives"  tab all compiler
directives as they are. A keyword "declared" is known for identifier
completion (but not for code creation tool).

Yet one observation - adding {$MODE DELPHI} changes nothing.

You know probably all, but the thread is not closed ...

This works too:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i program
Project1;//{$if declared(xisntthisabugx)}{$if
defined(xisntthisabugx)}const  xisthisabugx = 'xx'; //black line,
should have been grey - NOW IT IS GREY{$endif} //{$if
declared(isntthisabug)}{$if defined(isntthisabug)}const  isthisabug =
'yes'; //black line, should have been grey - NOW IT IS
GREY{$else}const  isthisabug = 'no'; //grey line, should have been
black - NOW IT IS BLACK{$endif}begin  writeln(isthisabug); //writes
no,  AND IT IS OK  readln;  //Obviously, the following line fails to
compile  //writeln(xisthisabugx);end.

I was surprised to notice this Lazarus behavior because by changing
the colour of the text in the editor it misleads the developers.
