I don't mean "go crazy with the images". As Michael mentions - it costs
disk space. A lot more that text-only bug reports. Sometimes a
screenshot is needed to explain a problem, but if you can explain it
without a screenshot, all the better.

Other space saving tips:
 * Often a full desktop area, or whole window dump is not required.
   Select only the area of interest for the screenshot.
 * PNG's are most used, but can be large because they are lossless. Use
   Indexed PNG's instead. They can have an optimised 256 colour palette.
   More than good enough for a bug report and normally a fraction of the
   original size. (The Gimp: "Image -> Mode -> Indexed").
 * Don't include videos in Mantis, they are WAY to big. Upload them to
   a reliable source like YouTube or Vimeo and reference the URL
   instead.

[Lazarus] IDE Desktops redesign

[Ondrej Pokorny]

According to some recent discussions and bug reports, I plan to rework 
the Desktops feature in the IDE. Before I again get a "Please stop the 
IDE regressions!" messages, I decided to announce and discuss the topic 
in the mailing list in advance.


The redesign will include the following points:

1.) Removal of IDE Options -> Environment -> Windows -> Window Positons.
Why: The desktop features duplicate "Restore window geometry" and 
"Custom window geometry" settings. The other two settings ("Let 
windowmanager decide" and "Fixed default geometry") seem useless for me. 
The options also conflict with Desktop window layout.
Column widths and other window layout settings will be saved through new 
generic interface.


2.) Moving options that are saved in the desktop into new IDE Options 
category "Desktop" (within the same IDE Options dialog).

"Environment -> Window" :: "Desktop -> Window"
"Environment -> IDE coolbar" :: "Desktop -> IDE coolbar"
"Environment -> Editor toolbar" :: "Desktop -> Editor toolbar"
"Environment -> AnchorDocking" :: "Desktop -> AnchorDocking"
Why: just to make sure people understand that these settings are saved 
in the Desktop and change when Desktop is changed and that they are not 
IDE-wide.


3.) User-configurable options (from IDE Options) will be always auto 
saved just like all other options are. The "auto save" setting from 
Desktop Manager will affect only window layout that is not manually 
configurable.

I've wanted this feature for a while. I think adding simple global property
on TToolBar to show/hide captions would suffice.

In the interim here is a workaround, editing the IDE while it's running:

I just installed lazarus 1.6 in a Linux Mint 17 (Cinnamon) virtual
machine on my laptop.
In this environment I can also size the different windows fully.
So the problem I reported must be due to the platform it is installed
on (Raspbian Jessie on a Raspberry Pi2 in this case).

Note that the sizing is a problem both via remote connection
(TightVNC) and directly with the monitor hooked to the Rpi2.

Strange problem

Thanks, I just read the comments of that report. My suggestion it to
apply the changes to all ide windows similar to Project Groups, Project
Inspector, Package Editor etc. I'll apply it to one, and if the concept
works, I don't mind applying it to the others.

From what you described, it sounds like over-engineering for what the
actual problem is (reduce screen size and still have quick access to
items). A [☰] icon showing a standard popup menu should suffice. The
hamburger menu could be triggered via some standard keyboard shortcut.
eg: Ctrl+Space or something. The Spacebar matches the hamburger lines
nicely. ;-) You can then select the menu item with arrow keys or a
hotkey. No complexities of searching, filtering, magically reordering
menu items etc. And all still possible with the keyboard (and mouse).

In fact, I have a 12 hour flight coming up where I need to kill some
time. Maybe implementing some of these ideas as a prototype/suggestion
is a nice way of making the time fly by. ;-)

A sort of.
But directly invokable via shortcut key and with filter and/or sorting.
A (possibly long) list of text entries but you can type some characters and
it immediately filters the list to the matching entries only (as in the 
component/view all-dialog).
They could be sortable by last usage or lexically (or others) by the user.
Windows start menu search finally uses this too (although this has other 
issues).

Or a tree like list where typing takes you to the next matching entry and enter 
invokes it.

When programming I would not like to move away my hands from the keyboard to 
reach for the mouse.
That's not ergonomical.

As Michael mentioned... in other words, a Menu. ;-)

I do actually agree that the images don't often mean much. My idea is to
have both icons and text shown on such toolbars. Once you are familiar
with there functionality (and if you use the IDE daily as your job - it
should be soon), then disable the text. In the case that you forgot what
a toolbar button (image only) means, the tooltip will come to your
rescue in 0.5 seconds.

In normal terms I would say text makes more sense (hence I have images
disabled in Lazarus's menu items), but for the toolbars I'm talking
about, the text takes up too much space.

As for dropping the toolbars completely in such ide windows, and using a
popup menu (eg: via a "hamburger" [☰] icon) instead I would actually
like that very much.  A right-click menu might be problematic (hence my
suggestion of a ☰ icon), because such popup menus are often context
sensitive. eg: In the Project Group window, if you right-click on the
treeview, you don't get the same options as the toolbar.

Tested again. Same lazarus executable... all my custom packages

with a new lazarus profile directory works. That same executable with my

Either way... I really need Project Groups, so going with the new

[Lazarus] Feature Request: hide button text in windows with toolbars

[Graeme Geldenhuys]

Hi,

In the "IDE Options -> Environment -> General" you can disable images on
buttons (in ide dialogs) and menus.

Would it be possible to have another option to disable text in ide
windows that have toolbars? Take a look at the attached screenshot. Many
ide windows look like the red rectangle (that isn't zoomed in the
screenshot, that's actual size). Yet look at how much less space is
taken up by the toolbars in the green rectangles.

These massive toolbars are wasted screenspace, and if you resize windows
like the Project Group window and make it narrower to fit the content of
the treeview better, then I get 3 rows of buttons - waisting even more
vertical space!

A image with a tooltip should suffice. The added text is just bloat.


Regards,
  - Graeme -

The combination of packages that triggers this problem is  
lazdatadict+lazprojectgroups,
the problem appears only when the most recent project groups list is empty  
(this is when the MRPG submenu is hidden). The problem is an inconsistency  
on the counts of menu items between some internal list and the physical  
"project" menu items.


The issue has already a report:  
http://bugs.freepascal.org/view.php?id=29675


For myself I fixed the problem here but it has a side effect that prevents  
me committing the patch, the main menu appears inverted: Help, Windows,  
Tools, etc... Search, Edit, Files.  :)

[Lazarus] Is there any alternative to PPL (Parallel Programming Library) on FPC?

[silvioprog]

Hello,

Just a quote from Embarcadero doc

:

The RTL provides the Parallel Programming Library (PPL), giving your
> applications the ability to have tasks running in parallel taking advantage
> of working across multiple CPU devices and computers. The PPL includes a
> number of advanced features for running tasks, joining tasks, waiting on
> groups of tasks, etc. to process. For all this, there is a thread pool that
> self tunes itself automatically (based on the load on the CPU’s) so you do
> not have to care about creating or managing threads for this purpose.


To check it, we can take a small example (full source here
)
that looks for prime numbers using a classic for loop:

var
  I, Tot: Integer;
  SW: TStopwatch;
begin
  Tot := 0;
  SW := TStopwatch.Create;
  SW.Start;
  for I := 1 to Max do
if IsPrime(I) then
  Inc(Tot);
  SW.Stop;
  WriteLn
(Format('Sequential For loop. Time (in milliseconds): %d - Primes
found: %d',
[SW.ElapsedMilliseconds, Tot]));
end;

The result:

Sequential For loop. Time (in milliseconds): 764 - Primes found: 348513

Now, a similar example however using PPL:

var
  Tot: Integer;
  SW: TStopwatch;
begin
  try
Tot := 0;
SW := TStopwatch.Create;
SW.Start;
TParallel.For(2, 1, Max,
  procedure(I: Int64)
  begin
if IsPrime(I) then
  TInterlocked.Increment(Tot);
  end);
SW.Stop;
WriteLn
  (Format('Parallel For loop. Time (in milliseconds): %d - Primes
found: %d',
  [SW.ElapsedMilliseconds, Tot]));
  except
on E: EAggregateException do
  ShowMessage(E.ToString);
  end;
end;

Result:

Parallel For loop. Time (in milliseconds): 315 - Primes found: 348513

Awesome, I got a nice performance using PPL and it seems a nice feature,
but where can I get anything like this for FPC?

Thank you!

[Lazarus] Project Groups error - "Invalid floating point operation"

[Graeme Geldenhuys]

Hi,

I've just upgrade my Lazarus to the latest trunk revision on my native
FreeBSD system, and in a Linux VM. On FreeBSD the IDE seems to work, and
I can use Project Groups.

In the VM I get instant IDE crash with the error message "Invalid
floating point operation".  I know about previous "index out of bounds"
errors, which is believed to be caused by various installed packages. I
must add that my Lazarus in the Linux VM has a lot more packages
installed than the copy on FreeBSD.

In both cases I used 64-bit FPC v2.6.4 to compile Lazarus. I did a 'make
clean' before I did a 'make bigide', and then a "Options -> Build
IDE..." to get my custom installed packages.

Anybody else see this error yet?

I did some more testing. As soon as I remove "project groups" package,
then the IDE runs fine with my collection of installed packages. Install
"project groups", and then I get this error again at startup.

Yeah just have seen some posts coming through on it this morning (posted

there is however no history (the archive has not been imported yet) so only 
really new messages appear;

and Gmane devs / staff give themselves a lot of play in timelines definitions 
(see gmane faq)... 
(which is not really that surprising given their manpower and being volunteers

It's definitely not a browser problem, unless the basic FPC site

They are organized basically the same as any other IDE command list,

Ctrl-Z is not implemented. The "removed targets" allow to easily spot
accidental deletions and to examine the removed target.

[Lazarus] Feature request: Project Groups

[Graeme Geldenhuys]

Hi,

Just updated my lazarus to the latest Trunk revision. I'm very glad to
see Project Groups are available and working well thus far. A highly
sought after feature for many years.

One suggestion though. Can the "current project" be highlighted in Bold.
At the moment there is no way of seeing which project in the project
group window is the active project.


Also, what is the point of the "removed targets" tree node? I'm assuming
when you remove a project from the group it appears under the "removed
targets" node. But why would you want a removed project to still hang
around in the project group window? You removed it for a reason right?
If you want to undo an accidental remove, doesn't simply not saving the
group, or Ctrl-Z, or your SCM system handle that for you? It seems we
already have plenty of "undo" choice, and the "removed targets" is just
overkill.

Regards,
  - Graeme -

It does now for fpc-other at least

gmane.comp.compilers.free-pascal.social = fpc-other ... recently added (less 
than a week ago)

don't know whether lazarus-other has been submitted to Gmane yet,
not sure whether it's the list admin that needs to do that; probably yes;

I cannot resist chipping in here but i honestly cannot think of ONE 
thing thati mproved following a microsoft acquisition, 
truespace(acquired in 2008 or thereaboiuts) abandoned. no longer 
supported despite it being well regarded by many. oh and look what 
happenned to the "partnership" between Microsoft and Nokia!! MS has had( 
and probably still has a habit of) acquirng( or attempting to acquire) 
any company or entitiy that it sees as a potential threat, then grinds 
that company or entity to the ground.

end of rant. ;-)

In general it is better to explicitly handle your transactions.
However, if you don't do that, then SQLDB will do it for you.


So as long as there is a TSQLTransaction object hooked to the
connection and query (same transaction object) then the built-in
system will do the StartTransaction-Commit sequence in the background
if I do not explicitly code for it?


StartTransaction, yes. 
Commit: I do not think so (would need to check).
