Re: [fpc-devel] FPC 2.2.3 i386-darwin snapshot
You've gotten farther than I did.
I can't get anything from pascocoa to compile, it complains about
missing units.
And the missing units are not included in the pascocoa sources, so no
idea where to get them.
(don't remember which unit is missing, will check later and write again)
What did you do to get pascocoa to work under osx?

FWIW, I just discovered that it does not fully work in 2.2.4 either

I.e., you cannot call one static class method from inside another
one (removing the "static" makes it compile).

This is a new feature for FPC, right? (catching up with new delphi

The static keyword been available forever in FPC (probably from before
Delphi had it, we first used it in TP-style objects). What is new is
making the behaviour of adding of "static" to class methods Delphi-
compatible.
a few questions about that:
1) 'static' methods are regular procedures/functions, but bound to a
class rather than a unit?
A class method becomes indeed a regular function/procedure within the
scope of a class if you add "static;".
2) it's possible to pass 'static'-methods as procedure variables?
Try it. I don't know. It will probably cause compiler errors because
of type incompatibilities. If Delphi accepts it in some form, please
file a bug report with a compilable example program. It should
probably also be tested that class methods are not assignable to a
"procedure of object"-style procvar (although I don't know whether
that's normally possible for class methods).
3) only class methods can be 'static'? it's impossible to declare a
method like:
TMyObject = class
procedure MyMethod; static;
end;
It's possible to declare this, but it doesn't change anything
currently (a method without self-parameter would be indistinguishable
from a class method without its hidden vmt-parameter -- which is also
called self, for that matter). I don't see any use for this.
4) no Self parameter is available inside the 'static' method. (since
it's regular procuder or function)
That's the whole point of using static.
5) 'static' keyword is used only if compiler -St switch specified?
Yes, or {$static on)
6) how are they actually named? because there're two kind of static
methods available:
TMyObject = class
class function MyClassProc; // static class method
This is a regular class method.
class function MyClassVirtualProc; virtual; // virtual class
method. can be overriden.
class function MyClassVirtualProc; dynamic; // dynamic class
method. can be overriden too
class function MyClassProc; static; // "static" class method?
And this is a static class method.
7) 'static' keyword is available for both {$mode objfpc} and {$mode
delphi}
It's available in every mode, as long as you add -St or {$static on}

All I remember about static is that you explicitly asked for a particular revision to be merged a couple of weeks before the release, also because you needed it for Cocoa. Did you ask for a merge without testing either before or afterwards? If so, I really hope you won't do that again in the future, because it completely destroys the value of release candidates.
