It is ignored in mode Delphi, not in ObjFPC.

[Lazarus] Code Tools Feature request

[Michael Van Canneyt]

Hi,

When I want to get information on an identifier, sometimes the 'jump to 
declaration'
or the tooltip with declaration info do not appear, because the source code
contains errors.


Example source code:

-
Function TMyClass.SomeMethod(AnArgument: String) ;

begin

end;

procedure TMyClass.DoSomethingElse(AnArgument : String; Options : TMyoptions);

-

if I hover over TMyOptions, then I get nothing. If I want to ctrl-click it,
it doesn't appear as a hyperlink (as it would if all was OK).

The reason is of course that the function declaration right before it is wrong.
(it misses the return type). That's OK.

But what I would like to see is WHY I'm not getting any info... 
Presumably this is the error the code tools produce when looking for the info ?


Is it doable for the messages window to show this reason ?

Michael.

I started typing about this when your message landed here :)

Another problem I found is that sometimes if I click in the designer
area it scrolls the content and the bottom scrollbar is fully covered.
Scrolling down with the scrollbar on the side will slowly reveal the
bottom scrollbar. Linux/GTK2 screenshot attached...

On Linux/GTK2 when I edit the caption of the menu in place (inside the
designer) I can drag the window but the active text input field does not
move with it.
See attached screenshot...
Also the scrollbar issue I found is visible on it.

OK, when I hover the mouse over the error message in Lazarus there is
additional info about it. It says that it is missing the corresponding
PPU file...
So I searched for it:
sudo find / -iname lnet.*
/usr/share/src/fpc-2.6.4/fpc/utils/fppkg/lnet/lnet.pp
/usr/fpc/3.0.0/utils/fppkg/lnet/lnet.pp

So there does not seem to exist an lnet.ppu file.
How is that created? When compiling fpc or as part of building an
application that uses it (would be what I'd assume)?

I installed fpc using the make functions in the source:
sudo make all
sudo make install sourceinstall
Maybe it does not really build the full system?
Is there a command to actually also create the ppu files?

What were your problems? In r51298 I removed all the Scroller code and

No, I did not install it. This is one of the first tests following

Do I have to install non-visuel components in Lazarus? I usually

Same compiler as before (3.0.0)

I only have fpc 3.0.0 plus the seed 2.6.4 on this computer (Raspberry

Furthermore:
I had a look in Lazarus RC2 and I could not even find the lNet package
listed among the ones that could be installed/uninstalled.
Nothing in the "Installed" list and nothing in "Available for
installation" either.

So I don't even know how one could install this package...

I am still wondering why it won't compile when the IDE clearly finds
the unit file?

I've also noticed this recently. Is this new behaviour in Lazarus? I'm
pretty sure it wasn't always like this. Is CodeTools more sensitive to
source code errors in recent Lazarus versions?

Did you install lnet via fppkg?
Maybe you updated your compiler and forgot to update lnet?
Also check that you have only one lnet.ppu.

A missing function type raises an error since many years.

In order to parse some new syntax features some errors are no longer
ignored. So yes, you could say it got more sensitive to errors.

I have a test project that I try to run using 1.6RC2.
In the source editor I can right click the uses line where lNet is
specified and select "Find declaration" and it opens the unit in a new
tab.
But when I try to build the project there is a message:

"lnet" is a normal unit of FPC.
Compile with -vut to see where the compiler searches and what it finds.

Packages only need to be "Install"ed if they provide IDE addons.

That's the place where fppkg needs it during compilation, yes, but not
where the compiler would and should find it. The user should use fppkg
(just a coincidence that both times fppkg is involved here) to install the
package (AFAIK "fppkg install lnet").

Is that a command in terminal inside the fpc source dir:
/usr/fpc/3.0.0/
or somewhere else Like:
/usr/fpc/3.0.0/utils/fppkg/lnet/

Or is it inside Lazarus somewhere?

A search for fppkg gives this:

It is a bit confusing, that lnet is in FPC sources, but needs to be
installed by fppkg.

[Lazarus] FileExistsUTF8 and long paths

[Jürgen Hestermann]

With Lazarus RC2 (and I think before too) "FileExistsUTF8" uses
"_FileGetAttrUtf8" which again uses FileGetAttrWide (on Windows if Unicode is 
enable)
which again uses "Windows.GetFileAttributesW(PWideChar(UTF8Decode(FileName)))"

but this fails for long paths (if Length(FileName)>255).
Why not prepend "\\?\" at this last Windows step so it works for long paths too?


BTW:
I am not sure whether this leads to errors but while the result of the Windows 
API-function
GetFileAttributesW is declared to be DWORD
this result is converted (or is ist just typecasted?) to Integer in

function FileGetAttrWide(const FileName: String): Longint;
begin
Result:=Integer(Windows.GetFileAttributesW(PWideChar(UTF8Decode(FileName;
end;

Doesn't this provoke at least a range check errors?
What happens when I compare the integer result with (DWORD) constants which 
havbe the first bit set?

This seems to be done at many places with many DWORD results from Windows API 
functions.
Is this a bug?

fppkg needs socket support, but that was needed before our own
implementation was ready enough, so lnet was imported directly into fppkg
as to avoid the appearance that lnet is distributed in the fpc sources.

[Lazarus] Web vs desktop development

[Anthony Walter]

On a programming web forum someone said regarding Lazarus:

On just cursory review, looks compelling. However, I get so little call
these days for native/desktop applications. Seems everyone wants web now.

I replied:

I agree that web applications are far superior in many situations. Compared
to desktop applications they are much easier to deploy, much easier to
upgrade, they work across multiple platforms, the user experience is much
richer (easier to layout, video, audio integration, css transitions), data
handling is easier (no need for local database server or local database
connection configurations), and of course web applications go much better
with the software as a service subscription or pricing model.

That said, desktop applications have a better time working with local
resources like files, scanners, printers (though cloud services for storage
and printing make this less relevant), are usually more responsive, they
obviously have better desktop integration (copy and paste, drag and drop),
usually have better user interface layout management (docking windows,
toolbars, menus), better performance, better direct access to memory data
structures (think of images editing accessing pixels, editing audio
waveform samples), and are better for applications which require long time
processing like encoding videos or recording audio.

That said, I prefer desktop software for doings tasks, which I think is
what most computer enthusiasts want to do. I write desktop software to
automatically scan Craigslist and eBay for collectibles which interest me.
I write desktop software to monitor video feeds with OpenCV. I write
desktop software to make games with SDL2/GLESV2. On so on ...

I guess what it comes down to is this:

For businesses web development is probably a better fit for their software
needs.

For people who are computer enthusiasts that use their computers to process
tasks or solve problems, desktop development is probably better.

What are your opinions on the subject title ?

I think you're missing security considerations as well.

When a desktop application is compromised, it's likely that only a
particular user would a victim.
For web-applications, all users might be compromised as well.

The trend is actually switching to web+desktop applications. I.e. Steam
client or Delphi's "help" window.
So each application is a browser on its own.
A smarter framework might suggest an alternative to html+js, so it could
integrate with any application easily, rather than for a browser
application.

Dmitry

Did so but I was confused about the statements there regarding the
extra line to add to /etc/fpc.conf
Not clear enough in my view regarding the *exact* looks of the line.

But I looked through my fpc.conf file and found this, which looks
similar to the wiki page:

# searchpath for fppkg user-specific packages
-Fu~/.fppkg/lib/fpc/$fpcversion/units/$FPCTARGET/*

Note that it says $FPCTARGET at the end rather than $fpctarget (case
not sensitive here?)

In any case I did not edit the conf file but instead launched
fppkg install lnet

and after a minute or so I got this:

Lazarus directory '/home/pi/.fppkg/build/lnet/' does not contain a
valid Lazarus installation. Lazarus-package registration skipped.
Installation package lnet for target arm-linux succeeded

What does it mean that registration skipped?

In any case my test program does build now using both Lazarus RC1 and
RC2.

Thanks for your help!

Trying to create a clean environment for my embedded RPi2 development,
my last installation is wrecked by too many experiments with fpc and
lazarus versions from svn and other things...
This one only contains the seed fpc 2.6.4, release fpc 3.0.0 and
lazarus RC1 and now RC2.

Real soon I will be able to get back to working on the real project.

Correct!



But would it be possible to show the error ? Try as I might, there is no

Well. The least I can say is that it is not clear to me when the IDE 
shows a codetools related error in messages and when not :-)


Yes, the error is shown when explicitely executing CodeTools functions, 
e.g. identifier completion (Ctrl+Space), or "Find declaration of ..." 
from the popup menu but not when just hovering with the mouse. Maybe 
this is intended in order not to having false errors reported all the

Re: [Lazarus] Web vs desktop development

[Anthony Walter]

+1 On security considerations.

I forget to mention that. Installing software on Windows has gotten so bad
with so many download sites or software producers bundling adware, or even
spyway and malware. Microsoft themselves seem to have thrown in the towel
with Windows 10, packing in key logging, location tracking, and even
putting adware in they system notifications.

All of these security problem have a negative effect on the good desktop
software developers (us for example). Most people are now trained, either
from the advice of others or their own experience, to reject installing
"stuff" from the Internet.

I've always been of the opinion that the web is great for displaying
information. To use it as the central processor bugs me.

When I ask my program to do something I want the attention of the
processor. I don't want it going over the web (security issues) and then
asking for some perhaps overworked server processor time.

Then there is the issue of throughput. When I have a client executable
all I need is the data, so much less iNet traffic.

I've always been for web+desktop app. Rest of the world disagreed. Nice
to see maybe it's coming back...to sanity!

FWIW.

These app will be better these days because we can use them in as a
website and an application with a same source and minor changes but one
thing that amused me is that why until now I didnt see anything good
from FPC and Lazarus people here? I know its a Open Source world and
 but I saw many great thing but not this,is there a problem or
disagree about making these apps in FPC? As you can see they will be
more apps like these and their problem is speed sometimes that it can be
solved with FPC easily.

Sorry, I'm not following any on them.

But, the biggest issue here is that most of the engines are C++ based.
FPC support of C++ classes is in initial state (and is on long term todo
list).
Thus building a bridge (i.e. C wrappers) for web library is required in
most cases.
So it's an extra step that a rare pascal developer would like to make and
maintain. And the quality of integration depends on the quality and
flexibility of created wrappers.

Take Qt as example -  C-wrappers are maintained by a single person and a
lot of Qt APIs is still missing.

Dmitry

I agree with your points, but I'd like to add something more.

I believe that the first task of a designer is to pick up the most 
*appropriate* technology to solve the given problem, without being 
influenced by what is fashionable, "modern" or "cool".


My favourite example are the newspapers and the tomb stones.

From the beginning of civilization, important news were graved in stone 
slabs.
When paper and printing were invented, the new technology appeared much 
more appropriate, and the stone slabs were replaced by newspapers. With 
the advent of the Internet, a new technology has become available to 
spread news and information, which is faster and cheaper, provides a lot 
of extra features, and it is replacing the printed paper technology in 
many domains. The most appropriate technology prevails.


When it comes to a tombstone, it's stone age technology, but up to now 
nothing better has been found to put over a grave than a graved stone, 
so the stone age technology remains the most appropriate choice.


The same technology has been obsoleted twice for one application, but 
remains the most appropriate for another.


If an application is meant to run locally, with local data and local 
resources, making it a web application will inherit all the 
disadvantages of web, without any advantage. It would not be the 
appropriate choice.


If an application is run by a number of users scattered in different 
places and takes advantage of common information which can be held in a 
common server, then a web application is the best choice.


Intermediate cases must be carefully analysed, evaluating pros and cons, 
to pick up the most appropriate solution. A straight assumption "web is 
better" or "desktop is better" leads to poor results, if not to failures.


I'm running a consultant company, and frequently we have discussion with 
our customers trying to tell us not only what they want, but also how we 
should do it.
We always tell them that we may guarantee a good result only if we're 
free to pick up the most appropriate solution, disregarding the fashion 
of the day.
That way, in over thirty-five years of activity, we never failed a 
single project. I consider among our successes the few instances when we 
have been unable to convince our customers to accept our way, and 
therefore we decided to turn them down. They addressed elsewhere, and 
failed!


My 2 cents,

Giuliano

This will break existing programs, including the ide.

Currently you can use both / and \ in filenames on Wndows filename
functions, because the API does not care.
That is unlues you prepend \\?\, then character in the given string
MUST be in the filename.
Also this will then return false on '..\foo.bar', sincenow te APi
expects that the two dots are part of the filename.

See the comments in ExpandFilenameUTF8 (I think I put a reference there).
