I don't agree, that's what file extension is for. Filtering and sorting
should easily be done to distinguish package files from others.

Fully agree.

I feel I should also add that DOS is not the mainstream OS any more like
it was in the early 90's (some 26 years ago), so why is everybody still 
limiting file extensions to 3 letters?? Some of my fpGUI included 
applications use file extensions like *.project etc. Hell, even 
Microsoft is catching up with that idea (although minor) and now use 4 
letter extensions like *.docx etc.

Right click on an unit in the package editor and set File Type to "Main
Unit". That is then the auto generated unit.

Here is how to create a new package with this:
http://wiki.freepascal.org/Lazarus_Packages#Create_a_package_with_a_unit_that_has_the_same_name_as_the_package

If you often need to create packages a custom main unit name, feel free
to create a new package type or an initial setup dialog.

I think, add a unit, select it in the list, right click it, and in "file

Maybe there is an easier way

SynEditDsgn has this

the auto generated unit is allsyneditdsgn.pas

and the unit with registration is "syneditlazdsgn.pas" (see checkbox at 
the bottom of package dialog.

So this as afaik why the unit will be called from the autogenerated unit.

The package unit can have a different name as the package. See

Don't think so. The gtk implementation should have checked this and probably

Imo the QT implementation should be adapted to behave the same.

We shouldn't "copy"the x behaviour, but behave the same as Delphi.

There is one moment: ATSynedit has

- atsynedit.pas (main unit)

- atsynedit_package.pas (with suffix)

You see suffix is useful here.

True. And this is unfortunate, because it is not functional at all.

The "problem" is that the pascal unit generated for a package has the
same name as the package and often conflicts with a unit in the package. 
IMO it would be better to prefix it automatically.  (fpmake does this when

it makes a build unit)

MyPackage.lpk -> build_Mypackage.pas
or maybe
MyPackage.lpk -> run_Mypackage.pas
MyPackage.lpk -> ide_Mypackage.pas
Depending on what you chose for package options.

That way you would not need to prefix your package name with anything, 
unless you split your package in a design and runtime package. In the latter

case the prefix (or suffix) is still functional: it tells you that it is run
or design...

Well, I think it is very important to distinguish between "runtime" and 
"design time" packages. One has very different dependencies and meaning 
compared to the other one.


Your idea of fpmake using automatic prefixes is good and all, but when a 
developer creates a package using Lazarus IDE, there is no "automatic 
naming" in play.


The "pkg" suffix is pointless indeed, that is what the file extension is 
for. But the "dsgn" suffix is commonly used to distinguish between 
runtime (no suffix) and design time usage.

[Lazarus] Strip symbols in IDE

Hi,
 
does the checkbox [X] Strip symbols from executble works well for you?
It does nothing here. If I then do:
>strip project1
in xterm, it works. I have "strip" installed in /usr/bin.
It seems that other options have no efect to it, except -Xg [X] Use external 
debug file.

Thank's for your reply.
I only have an old Delphi 7 version here - they all don't have the
Pattern option for TPen. When done manually, the ExtCreatePen function
of the Windows GDI also expects an array with the length(s) of
individual strokes in the pattern (see
https://msdn.microsoft.com/en-us/library/windows/desktop/dd162705(v=vs.85).aspx
), so I would expect newer Delphi versions to implement it that way
(same as on X).

Of course this is still MY failure, not any of the LCL...

Best regards,
Alex

Please check this kind of errors, with 1.8.2 (once released) or the bug

If an incorrect bracket is highlighted with the fix, then please report it.

Note that, brackets in strings or comments, will/should not be matched 
with brackets in code.


   if (a = '(' ) then // (
        a := ')';  // )

should match
- the 2 brackets in code
- AND the 2 brackets inside the 2 strings
- AND the 2 brackets inside the 2 comments

It should also match the correct quotes '.

Bracket matching only ever looks at one kind of brackets.
When matching (), it will totally ignore any [].
So erroneous code like
  if (a[1]] = 2) then
will match the ().
As well as the [] directly around the 1.
And the extra ] will not match anything.

OK, I see

Here if I put the cursor left of the ; I get hightlight properly.
