In LoadFromCSVStream.StorePart the Inc(leadPtr) needs to check if at end
of stream. I added that in revision 50144.

I see. I suppose the would-be MainThread is just the thread that is used 
to start the application. That does make sense. For the internal logic 
of the Lazarus application the fact that it calls CheckSynchronize() is 
what makes the difference.


Better usage of terms: Exceptions are thrown (or raised), events are

You are right. "thrown" is not a good wording for Events. I mostly read 
"fired" on that behalf.



CheckSynchronize completely walks the lost before it returns.

Thanks a lot for the correction. This is very important to me (see below).

> AFAIK the return parameter of CheckSynchronize() does not give any 
decent result and needs to be ignored.


That is indeed always "false" right now. I should check sometime what 
it is supposed to return... Probably whether at least one event got 
executed :/




Maybe the original idea was to have CheckSynchronize execute only one 
Event and return TRUE if more events up are to be handled.


With this (not existing) design, I would need to do something like:

procedure TmyApplication.ProcessMessages;
begin
while CheckSynchronize() do (*nothing*) ;
end;

With the current design just

procedure TmyApplication.ProcessMessages;
begin
CheckSynchronize();
end;

would be OK, but the code above would work, as well and maybe should be 
preferred for possible future extension.

"Signalled" is not a good choice IMO, because of unix-style signals and 
their handlers (e.g. sending a HUP signal to a process, to get it to 
re-read its configuration).


"Triggered" can have problems if a database is being used.

"Fired" seems like a fairly good choice, since it also implies immediacy.

[Lazarus] The GDB command: "-gdb-set confirm off" did not return any result

[Bo Berglund]

When I try to run a very small Console Application for testing Indy10
using the green arrow run button I get a pop-up message box saying:
The GDB command: "-gdb-set confirm off" did not return any result

If I build the program instead and go to a terminal window to execute
it, then it works as it should.

Environment:

Platform: Raspberry Pi2 with ARM7 running Raspbian Jessie
FPC 3.1.1 built from sources as root
Lazarus 1.5 SVN 50059 built inside the Pi home as user pi
Test sources in Pi hme as well
TCPIP: Using Indy10 copied over from my PC using a samba share
(so the files for Indy have Windows line endings)

What could cause the GDB problem? Line endings or what?

The active code apart from what Lazarus entered:

  { add your program here }
  Writeln('Creating TCP client');
  FComm := TIdTCPClient.Create;
  try
Writeln('Connecting to www.mydomain.com on port 80');
T1 := GetTickCount;
FComm.Connect('www.mydomain.com', 80);
T2 := GetTickCount;
T2 := T2 - T1;
Writeln('Connection succeeded in ' + IntToStr(T2) + ' ms, now
closing down');
  finally
if FComm.Connected then
   FComm.Disconnect;
FComm.Free;
  end;

BTW, Indy10 seems to work fine so far

Take a look at "Procedure List" found in the Search menu, or simply use
Alt+G  (I've changed mine to Ctrl+G). This allows you to type any text,
and the list shown will be reduced to show any partial matches. Down
arrow to highlight what you want, and ENTER to go to that code. No mouse
usage is needed. You can also use the combobox to limit matches to a
specific class.

I ported this to Lazarus many years ago, because this is by far the
fastest way to find specific code in large units - at least that is my
personal experience.

Using Editor Bookmarks are also a vital tool I use to jump to different
location in a unit, or even to other units.

Yea for you its just a normal unit but for someone like me writing this

[Lazarus] Hour of Code 2015

[Johannes W. Dietrich]

The Hour of Code is coming again!

The Hour of Code, a one-hour introduction to computer science, is a  
global movement reaching tens of millions of students in more than 180  
countries. In celebration of the Computer Science Education Week  
during December 7-13, 2015, its goal is to give every student the  
opportunity to learn the foundations of programming and information  
technology.


Anyone can organize an Hour of Code event, anywhere in the world. If  
you are a teacher, parent or potential tutorial partner you might want  
to register at http://hourofcode.com to support the movement.


The broad support of Lazarus and Free Pascal for a plethora of  
operating systems and platforms opens a great opportunity to  
communicate solid programming skills to students.

Regarding the GDB it seems like the problem disappeared when I changed
the line endings on the files I had copied from my PC via the samba
share and therefore had Windows line endings. I ran dos2unix on all of
them (except the binary files of course) and then restarted Lazarus
and tried again and now there was no GDB error message anymore.

What I really wonder about next is the fact that it is different from
in Delphi when one starts a command line program while developing.
In Delphi the black terminal window shows up and one can see the
progress of the execution there. In this case there was nothing, not
even a single message in the messages window. It was as if the program
did not run at all.
But it might be intended to be like this on Linux, this is my first
try really.

On Windows you should get a terminal, if your app was compiled as console.

On linux the terminal is just a device /dev/pty,  and the terminal in 
which the command is running does the display.


Lazarus on linux has a debug window (menu view) to show the console output

Ok, Codetools is used for many things but I meant the settings
affecting automatic code generation. See pic.
Easily half of your code gets generated automatically when you learn
to use the IDE properly.
Now you are using it wrong.

JCF is only good for importing code from somebody using strange
indentation style or something.

Is it so hard to understand that the class units were developed (a
long time ago) in Delphi7 with a target of a GUI program? Tens of
thousands of lines of code...
So it had helpers to show the recorded data in listviews and other
such GUI related stuff (like handling progressbars etc).
All of which does exactly nothing unless they have such components
assigned to them.

In this case I do not want to re-invent all of the communications and
data parsing code that is the main part of these units and which I
need to use in the lean and mean communications program I have to
build. So I do not want to rip the units apart and rewrite them if I
can avoid it. This is the only reason.
And I did get a working way to handle this by including LCL. No more
compile errors caused by these classes.

And my post at a late time in this thread was just to clarify this
situation, not to ask any more questions so there was no need for more
commenting.

Yes, my issue sounded like yours, but when I saw your example I
realized you found a different bug.

The UTF16 conversion was wrong. It was missing the ending #0 wide char.
I fixed that in revision 50146.

You are aware that even during its existance Silverlight was only a small
part of the .Net ecosystem? There are GUI desktop applications, server
applications including ASP.net, Windows Store apps, XBox games. Saying that
the discontinuation of Silverlight is the end of .Net appears very far
fetched to me. That's a bit as if the end of Symbian would have been used
to proclaim the end of Java...

About codetools really I dont know what it does and I never used  it and
I read Wiki page and didnt understand how it help code formatting.

Doesn't change anything of my argumentation... Silverlight was only a small
part of the Framework as well and most other parts are still used by others.

Right, my target is a command line program started by cron and with no
user interaction whatever. Could be thought of as a service.

But when programming it I need to use existing classes from Delphi in
which I will use a subset of the functionality only. No functions
dealing with user interface will be used at all, but in the same class
is embedded the bulk of the communications protocol and data
interpretation and translation and these I do need.

In any case adding LCL solved the compile problem for that unit.

My development machine is now also the target, a Raspberry Pi2, with
FPC and Lazarus installed but it is headless. So my interface is PuTTY
for command line work in Raspbian Jessie and for GUI (= Lazarus) I use
tightvncserver on the Pi and TightVNCclient on Windows 7.

It works fine except for some small glitches like the inability to
type { } [ ] $ @ \ | into the Lazarus code editor. I have to open the
system text editor and type it there then copy paste it into the
Lazarus editor
It seems to be some kind of problem with the way keystrokes are sent
in VNC and interpreted in the Lazarus code editor.
I can enter these chars into the Lazarus property editors of GUI
components though as well as in the Raspbian Text editor, all via VNC.

There is a separate thread about this here...

Poor chap.

I posted the results in many answers to your forum messages.

I  have now shut down Lazarus, then used a utility to change line
endings on all text files in the Indy10 directories.
When I now start Lazarus and hit the Run button, absolutely nothing is
shown, not even pop-up error
So I made a Clean Build operation and this succeeded, so then I hit
Run again and nothing happens.

What could cause this? Am I not supposed to see a terminal window or
similar pop up?

When I wrote it, immediate typing reduced the search results (partial
matching anywhere was automatically enabled - matching at start is
optional from toolbar), up or down arrow (while edit had focus)
automatically moved the selection focus in the result list. Pressing TAB
(while edit had focus) switched to the ComboBox, where up and down
arrows can be used.

Others have modified the code (sometimes good, sometimes bad) since it
got integrated with Lazarus IDE. Some of the original functionality got
lost (no icons in result list any more, doesn't remember column widths
etc), but the above mentioned keyboard actions should still work (I hope).

Re: [Lazarus] Working on big units

[Aradeonas]

No shortcut and search behave badly. Doesn't search very good and for me
cant find anything good.
For now I dont know how to edit Lazarus add ones and codes (and making
patches and ... ) but it is easy to make these works. I just good at
making from scratch not updating others code (Just using :p ) .
Maybe I do that when I began to make patch for Lazarus.

Terminal window as in controlling your program interactively (or at 
least seeing output) or as in showing you what GDB is doing?

Can you please supply a screenshot of your Procedure List dialog with
the text you entered and what the results where And very
importantly, an example of what wasn't found that you expected it too
(eg: procedure, function or method name). I'll then take a look at what
went wrong.

I use Procedure List daily, and it finds whatever I'm looking for.

NOTE:
  Procedure List only searches the current unit (what will include
  Include files used in that unit), and only searches for procedure
  names, function names or method names. Nested (local) procedures work
  too.

  If you want to find something in all units, then you need to use
  "Search -> Find in Files..."

As I've already said, that's a VNC problem. And again as I've already 
said, in most cases you'll do better running Lazarus over the SSH link.

In the next step the GUI units can be modified to be dummy or provide a

You use JCF for your own code while editing? It makes no sense.
Adjust the Codetools code generation settings to match your coding
style instead.

Using JCF will limit you even more if you start to use the new
language features like advanced generics, class helpers etc.
JCF's parser does not understand some of the syntax and nobody
maintains it actively.
Codetool parser on the other hand is maintained. That's why I have
created this report :

That still doesn't explain why the original Delphi code required a
TListView instance. TListView is purely a GUI component - so I'm very
puzzled.

If you needed a list of objects, and maybe an associated text string or
something, then use TObjectList instead. I honestly don't see why
TListView is need in any Console application.

[Lazarus] StringGrid1.LoadFromCSVFile problem

[fecske fecske]

I like to use the StringGrid1.LoadFromCSVFile() function.
It works but also randomly ​set to a last line of strange characters

​
In the CSV file normail view are not these characters. I checked csv files
in hex viewer and  are not these characters.


I did a test, I wrote a Delphi code in a delphi IDE with unique function
and stringgrid, and  are not these characters.too.
I use the same csv files.

What's wrong in the LoadFromCSVFile() function?

Please help me?
