The abstraction layers of sysutils and classes simply require space. Either
people has to live with it or don't use it. E.g. a simple uses of sysutils pulls
in a lot of code because of the rte to exception conversion including a lot of
resourcestrings etc.

Smartlinking with classes having virtual methods is not working because the
compiler _can't_ know which methods are actually unused.

OLE and COM are supported in FPC, but only on Windows. So in theory you
can automate OOo directly on Windows.

not in FPC 2.0.4, AFAIK, which is the current release.
I think you are talking of FPC 2.1.x.



IMHO a OOo interface should use OLE/COM on windows, and any other means
(for example python) on other platforms. Although I think that if python
can call openoffice, FPC should be able to do the same.

It's true, in fact pyuno is a DLL/so that implements a bridge on the OO
UNO APIs, but I have no idea how it works...

What about Insert Space after?


For "Insert space after" I only have Colon, SemiColon and Comma checked.


Does the 'preview' in the options dialog show these spaces?
(Environment -> CodeTools options -> Spaces -> Preview)


The 'preview' window is correct.  What in generated for Class
Completion is different to the preview.

This is not yet implemented.


No problem.



Yes. At the moment 'class completion' does not search/read the ancestor
class, so it can't know.



Thanks for the info...  I'll had the last two as feature requests to Mantis

Hi Darius, thanks for the reply.

Thank you, that worked.

Yes. The menu file is in the form: "Command=Open" and "Command=New". I 
need some way of Passing "New" or "Open" to my program once the user has 
selected  the menu item.

There is a default highlighter for xml.
You can edit the file extensions in the editor options, which are
highlighted by the xml highliter since I fixed a bug two weeks ago.

I know this is an old thread, but regarding Delphi silly .exe bloating, for
command-line apps, if you removed some units like forms or sysutils and uses
windows unit (and respective API - even for just one call to MessageBox
instead of ShowMessage) the .EXE would become say 50kb instead of 500kb.
Pretty crazy, maybe fixed at versions after Delphi7 (had told Borland guys
about it). Either the compiler didn't remove unused classes/code (in favor
of RTTI and dynamic stuff or something?) or it was some resources linked in.

In some case I had found that moving such units from interface to
implementation section at my units that the project was using it made the
size much smaller for the .exe

I'd expect OO to use XPCOM like Moz, but not sure what they used

Btw, are ActiveX controls supported (more or less)? E.g. could one place an
AX on a form? Is there any helper functionality about importing an AX (not
necesserily the types, just the reference for starters) and adding it on a
form? (you can talk to it via late binding [scripting say via PascalScript
or Python or whatever] if you don't have autoimported types from the IDE or
write the code for early binding yourself then)

Matlab has compiler (into C)

Who says interpretted languages aren't programming languages? But anyway,
there are compilers for Python (as I said in previous e-mail I've made
compiler for Logo [generates Pascal from it] and you can do similarly for
pretty any language combined with some small or bigger runtime [for
reflection or name/value dictionaries etc.] for the dynamic stuff)

Which filetypes does the Laz IDE now highlight? For example can it highlight
.XML or .XSL files? Since unihighlighter supports a ton of languages (have
contributed highlighter for Logo myself for example some time ago) I don't
see why the IDE shouldn't support all those and allow people to use it as a
universal programming editor if they wish so apart from using it for Pascal
projects (why use yet another text editor along with the nice Laz text
editor?). Delphi has been doing that too and VS.net does the same too, can
open and highlight many different filetypes and even provide intellisense
for many of them

Mozilla XPCOM is basically COM compatible (defined same strucure for
IUnknown interface etc.). However I wonder if the port to Kylix for
Python4Delphi uses COM at all. What is Python4Delphi, is it a python
interpretter or just an API port/wrapper for some Python
compiler/interpretter/engine? I don't think there's one Python engine, but
many that implement the language "spec", so the wrapper can choose another
engine for Unix or a very portable one for both Win and Unix. Anyway,
there's other COM implementations for Unix apart from XPCOM and one can
easily implement basic parts of COM anyway

You mean implement Python over ROPS or vice-versa? I think the 1st to be too
hard or impossible. I've made Logo over ROPS, but Logo isn't that complex
compared to Python I think (for example ROPS is not really OOP, since you
can't define class types, just consume them from the Delphi host)

OLE and COM are supported in FPC, but only on Windows. So in theory you
can automate OOo directly on Windows.

IMHO a OOo interface should use OLE/COM on windows, and any other means
(for example python) on other platforms. Although I think that if python
can call openoffice, FPC should be able to do the same.

It's possible, just embed FPC with the python "embedded" in OpenOffice.

Can you give further details?




ok, I try to give a brief overview, here I talk of FPC but read that as 
FPC/Lazarus, please:


look at the Python Documentation: Extending and Embedding 
(http://docs.python.org/ext/ext.html)


This chapter explains the ways to use python with other applications, it 
is C/C++ based but it is simple to translate all that in Pascal.


Here you can see the concepts of Extending python with C/C++/FPC and 
Embedding python in C/C++/FPC.


With this in mind you have not to port Python for Delphi to Lazarus, you 
can simply build a suite of (simple) units that make up the interface 
with the pythonxx.dll or pythonxx.so libraries, and this is possible 
respecting the multiplatform requirements of FPC.


Now, since you can easily launch python scripts or modules from an 
application compiled with FPC it is also possible to bind this 
application with the pythonxx.dll that OpenOffice installs with its 
binaries. This is an ordinary python distribution integrated with 
modules that interface python with the OO APIs.


Now you need to look at PyUno documentation 
(http://udk.openoffice.org/python/python-bridge.html).
Here you can see how to use Python and the Python-UNO bridge to issue 
commands to OpenOffice.


With FPC you can only excecute the python Uno Bridge outside of the 
OpenOffice process, this is a bit slow, but it is enough to launch from 
FPC a simple helloworld.py that opens an OOWriter document and writes in 
the document the usual "HelloWorld!" string (I tested this on Windows, 
and I have to test if it really works also on Linux).


(note: Issuing commands to OpenOffice can be easily done with Delphi, 
this is explained in the OpenOffice SDK, but it uses the Uno OLE 
automation bridge. Since OLE and COM is not available in other 
platforms, FPC doesn't support them, so, this approach is not available 
for it)


From here there is a lot of work and experimentation to do, since it is 
not enough to call python scripts to issue commands, but it is essential 
 to exchange data from FPC<->Python<->Office.


that's all by now, this is the idea. I'd like to hear some feedback 
about that...

[lazarus] Code completion formatted code incorrectly

[Graeme Geldenhuys]

Hi,

Using Code Completion (pressing Ctrl-Space) in the interface section
of a class, so I can override a method, formats the code incorrectly.
I have Lazarus's "CodeTools Options -> Space tab" setup to not include
any spaces in front of elements. No checkboxes are checked in the
"Insert space in front of" groupbox.


Problem #1:
This is how the original class has it's method defined. Notice that
there is no spaces in front of the colons and semi-colons.

public
 functionIsValid(const AErrors: TtiObjectErrors): boolean;
overload; virtual;


And this is how code completion inserts that method into a new class
where I am trying to override the method.  Notice the formatting is
different, it has spaces in front of the identifiers, colons and
semi-colons.

public
   function IsValid ( const AErrors : TtiObjectErrors ) : boolean ;
overload ; virtual ;


Problem #2:
Another problems, is that it doesn't put the 'override' keyword at the end!


Problem #3:
This is more a nice-to-have feature.  When I use the code completion
in the new class as show above, it inserts the code at the cursor
location, even if I am in the "private" or "protected" section of the
class. I think it could be more intelligent and know that the
overridden method must go into the same section as it was originally
defined, in this case the "public" section.
