[SOLVED] Suddenly IDE does not show hints

For example, whey I type

         memo1.

then methods/properties that I can use should be shown, but not.
currently

             template    ....
             template    ....

are displayed. Is this related with anything of options/project
options?

In my experience this happens when the code fails to compile (due to
some error in the code or due to some FPC internal error). Try Run ->
Clean up and Build. If that doesn't help try restarting Lazarus (also
worked for me a couple of times).

I thought you were  joking, but it is a real trunk issue.

Try Project/New Project ...

Select project type "Application".

Write "Form1." and you will see:

you will see:
And in messages it says: unit1.pas(25,1) Error: expected end., but
Form1 found. This happens because the code fails to compile and
therefore no meaningful autocompletion can be provided for this case.
Fix the code (e.g. put call to Form1 in some procedure) and it'll work
fine.

Am I not allowed to write "Form1."?

No joking, please.

No joking, please.

You are allowed, but in your example isn't compileable code (just as
Eugene Loza suggested).
Try to write your example like this and see the difference:
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 procedure
Test;begin  Form1.end;

The implementation section, like the interface section, is global. You
can only create subsections with global type/const/var in it, as well
as list procedures/methods.

That is, instead of this:

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 unit
Unit1; interface implementation // anycode - ERROR end. 
you just wanted to write this:

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 unit
Unit1; interface implementation   procedure test;  begin    // any
code - OK  end; end. 
to call test procedure from somewhere. But if you want to write code
in the unit itself, there is also an initialization section:

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 unit
Unit1; interface implementation initialization  // any code - OKend. 
In general, do not confuse it with a "program" that does not have
these sections. But it also specifies the code after the "global"
begin (similar to initialization):

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;   procedure test;  begin    // any code - OK  end; begin  //
any code - OKend. 
But the author of the topic did not specify the full code of his
program, so we can only guess that he has the same problem.

My program compiled and ran without any errors.
I was talking about the "HINT" box which pops up when I type in ".".
Now it simply works... but I don't know why it didn't work. Thank you
for your advices.

Quote from: egsuh on August 16, 2024, 07:44:27 ambut I don't know why
it didn't work.It seems to happen when there was some compilation
error "in the past", but sometimes (rarely but happens)  CodeTools
thinks that this error is still present and stays in "erroneous
state". As I've mentioned above - trying to compile (especially "clean
up and build" option which can also get rid of a lot of "internal
errors") or restarting Lazarus often helps.
Hmmm... now that you mention it, I need to try to pay more attention
to when exactly this bug happens and maybe find reproduction steps to
make a bugreport.

Most common reason (at least for me): I missed a closing ";"
somewhere.

Otherwise, everything Eugene, dseligo and n7800 said
