I opened this topic to maintain the Arabic language, i used the forum
because most Arabic users like use it, and it can send notification
messages (Mantis not do that)
I will use Arabic Language for that, sorry

عند تحرير ايقونة البرنامج، زر نسخ قبله إشارة %
من أدوات - "بناء لازاروس بالملمح" مالمقصود الملمح؟
مالمقصود بكلمة توصيف؟
احيانا تستعمل صيغ الأمر مثل "إلغاء الأمر" و أحيانا صيغة االمصدر "غلق"؟

هل هذه خاصة بالترجمة فقط ؟؟
هناك عدة علل خاص بالواجهات في وضعية
 BidiMode-bdRightToLeft
 ابلغت عن بعضها منذ مدة وتم حله وبقي البعض لم يحل
هل يمكن مناقشتها هنا ... أم اﻷفضل فتح قسم فرعي للعربية في منتديات  
Other Languages ؟؟؟

مرحبا
شكرا أخي زاهر لفتح الموضوع، والشكر لأخي أحمد عطا الله للإهتمام، في
الواقع لم أعلم بفتح زاهر للموضوع إلا من خلال الربط الذي وضعه أحمد في
دلفي للعرب فشكرا له.
هذه محاولة مبدئية لترجمة نصوص بيئة التطوير وملحقاتها في لازروس. وهي
محاولة ناقصة من حيث الكم والكيف، والكثير من الترجمات التي قمت بها -
سواء لجمل أو لمصطلحات - غير راض عنها شخصيا، ولكن لا بدّ من بداية،
وبعدها لابدّ من جولات ومراجعات مرة بعد أخرى.
بالنسبة ل: الملمح فالمقصود بها profile، أما توصيف فقصدت بها
configuration مجرّد اجتهاد.
أما بخصوص الاختيار بين اعتماد صيغ الأمر أو المصدر فأنا اخترت الأخير
(مجموعة عرب ايز يعتمدون صيغة الأمر)، وأراها من وجهة نظر شخصية وليست
موضوعية أنها الأكثر طواعية، خاصة وأن الكلمة بالإنكليزية تحتمل الاثنين
مثل exit  و play.

السبب بفتح الموضوع هو الاعلام الفوري عبر الايميل إذا كنت مشتركا في
الموضوع مما يسهل علمية التخاطب
@أخ خالد
لا بأس بالنسبة للصيغ
و لكنك فتحت علينا شغل كثير

Sorry, if I hijack this topic but maybe my question is related. Do you
right-to-left guys want the menu position and all other UI elements
aligned to the right as well? Maybe it was a rumor but I remember that
controls are better standard aligned. Please give me some advice how
to support right-to-left perfectly.

Thanks for your interest , The answer for your question is yes for
example
i send a bug report about the TreeView it is not aligned correct in
Arabic

http://bugs.freepascal.org/view.php?id=22643  

about the menu is also should be to the right and lazarus shows it
weel in the IDE

----------------------------------------------------------------------
shagrouni · 2012-08-21 17:36

Currently the top main menu in the IDE is not aligned properly, it
should be reversed, the most right item should be ‘File’ not ‘Help’.

----------------------------------------------------------------------
a.atalla · 2012-08-21 18:05

it is aligned here (version 1.1-svn)  but the components in each
pallet tab should aligned to the right to
and the tool buttons (which contain the green arrow for RUN ) should
move from the left to right

----------------------------------------------------------------------
shagrouni · 2012-08-21 18:31

Strange! here what I have (screen shot attached), and its 1.1 svn:

The form caption is RtoL aligned.
The top menu while its aligned from right to left; the order of the
items is not correct.
The page control which contains the tools pallet is LtoR.

your question is yes...Okay, I'll add a switch to my application.
Actually, I'm looking for Farsi translation, which might be a good
test for this option.
Tabs (TPageControl) and toolbar controls are still left aligned. Is
this correct?

QuoteTabs (TPageControl) and toolbar controls are still left aligned.
Is this correct?I am Using Windows 7 and the Page Control is left
aligned.

a.atalla · 2012-08-22 17:17

Mine is GTK2  on Ubuntu  12.04 and the page view is showing correct in
Bidimode  righttoleft

No problem about PageControl, the problem in MainMenu, i will try to
reproduce it in simple application and fix it (ان شاء الله).

Hi guys,

Just found a message by Martin Friebe on the Lazarus mailing list:
http://www.mail-
archive.com/lazarus@lists.lazarus.freepascal.org/msg34715.html
QuoteA while ago, I started adding support for mixed LTR/RTL  text in
SynEdit.

The actual display of RTL text now works (that is, if you have some
arabic chars in the text, they display RTL, and the caret moves
accordingly / caret between RTL and LTR always means caret at LTR).
uf8 LTR/RTL markers are not supported. This is absolute basics only.

Unfortunately with RTL came other unicode features, that sofar no one
had missed. Those are at the very least
- combining codepoints
- ligatures
- maybe reordering of codepoints.
- other?
They are tasks of different extent. And I need to find out what is
mandatory, and what optional. So I can then decide, what does fit into
my schedule.

The current state is:
- combining: Only Arabic has been done (but they should be complete).
So none Arabic RTL will not work.
- ligatures: see below
- reordering: not researched, hopefully optional.

"work"
means, that the text is stable (except ligatures, only with
workaround), and does not expand/shrink, when selecting text, or
moving the caret. Also that the caret will be at the correct pos. A
newly inserted char will be where the caret was. Can be tested by
hitting the "end" key, and see if the caret is at the end of visual
text. If SynEdit thinks the text is shorter/longer than the actual
painted display, then there is an issue.

ligatures:
The editor does not handle ligatures yet. So it calculates 2 screen
cells, when only one is needed. However a stable "workaround" exists
(currently depends on config)

On windows and windows only (others will be done, if that turns out to
be any good). In Options / Editor / Display / set "Extra CHAR spacing"
to 1
This will slightly widen the script, ignore that, its temporary.
Requires a proper monospaced font. (Deja vu mono)

What it will do: It will tell windows, that the ligature is expected
to cover 2 display cells.
Display: Arabic text is a script, glyphs are connected by a continuous
line. The ligature will be in one cell, the next cell will be empty,
except for the connecting line.
Editing: The caret can be at either cell. Each cell stands for one of
the 2 chars in the ligature. So the 2nd char can be edited, if the
caret is at the empty cell

------------------
I need feedback from people who actually speak (or at least read and
write) Arabic. I need to know, if the above situation is "useable".

If so, then:
- it can be fixed to work without the extra char spacing
- on gtk, carbon, qt (well at least I hope)
- combining can be added for other languages.

If not, well I don't know yet.

Thanks,
BigChimp

For Window ONLY!  This code will mirror most TWinControls including
TForm and make them function RightToLeft.  It solves many problems,
but not all of them.  You should leave BiDiMode:= bdLeftToRight.  You
should call RtlCtrl for each TWinControl.  You need to include
'Windows' in the Uses statement.

A few of the known issues:
TMenu/TPopupMenu Images, TBitBtn, TSpeedButton Images, TSynEdit,
TButtonPanel...

Edit:  I forgot to say that you MUST disable Themes for this to work. 
Go to 'Project\Project Options' and UNCHECK 'Use manifest...'  If you
do not then TWinControls that are RightToLeft will be Black and not
usable.

Code: [Select]
uses Windows;

const
  RightToLeftLayout = $400000;
  NoInheritLayout = $00100000;

{===== RtlCtrl =====}

procedure RtlCtrl(ACtrl: TObject);
{ Make TWinControl RightToLeft - Windows ONLY! }
begin
{$IfDef Windows}
  if ACtrl is TWinControl then
    with TWinControl(ACtrl) do begin
      SetWindowLong(Handle, GWL_EXSTYLE, GetWindowLong(Handle,
GWL_EXSTYLE)
        or RightToLeftLayout or NoInheritLayout);
  end;
{$EndIf}
end;

{===== LtrCtrl =====}

procedure LtrCtrl(ACtrl: TObject);
{ Make TWinControl LeftToRight - Windows ONLY! }
begin
{$IfDef Windows}
  if ACtrl is TWinControl then
    with ACtrl as TWinControl do begin
      SetWindowLong(Handle, GWL_EXSTYLE, GetWindowLong(Handle,
GWL_EXSTYLE)
        and RightToLeftLayout and NoInheritLayout);
  end;
{$EndIf}
end;

I would like to know a couple of things:

1) which GUI toolkit supported by Lazarus do you recommend for Arabic
and BiDi?

2) does it support writing Arabic text and English text on the same
line?

As for the source-editor/SynEdit.

Under Windows (currently only windows) you can define
WithSynExperimentalCharWidth and recompile the IDE/SynEdit. Then you
should be able to type mixed RTL/LTR
