[Pyobjc-dev] build problems

[burris e. <bu...@gi...>]

Am I the only person that hasn't been able to build cvs in a week?  I 
get an error like this:



   File "setup.py", line 96, in create_cached_class_list
     m = __import__(name)
   File "build/lib.darwin-7.3.0-Power_Macintosh-2.3/AppKit/__init__.py", 
line 13, in ?
     from _AppKit import *
RuntimeError: Wrong version of PyObjC C API


thanks,
burris

It does now. According to my experience, and according to the 
documentation (INSTALL):

       With Unix-based systems, you can enable support for SSL from the
       Subversion build provided that you are building Neon in the
       "./neon/" directory as described above in section I.4.  You also
       need OpenSSL installed on your system.  Just add "--with-ssl" as
       a parameter when you run Subversion's "./configure", and it will
       be passed on to the Neon build system.  If your OpenSSL
       installation is hard for Neon to find, you may need to use
       "--with-libs=/path/to/lib" in addition.  The zlib library is
       included in Neon by default, but you can also specify a path to 
the
       library using "--with-libs".  Consult the Neon documentation for
       more information on how to use these parameters and versions of
       libraries you need.

Perhaps you were using a version from trunk where that functionality 
was temporarily broken? I still agree that the binary installer by Mr. 
Ott is excellent, and unless one wants to build an Apache2 server with 
Subversion support there is little reason to bother with the source.

The problem is that it's neon that requires those flags, not the 
toplevel configure script.  The toplevel configure script doesn't pass 
flags down to neon, at least last time I tried.

In any case, double clicking a binary installer is quicker than 
compiling something yourself even if the configuration was 
straightforward.

I'd prefer to do the conversion after the 1.1 release, which should be 
as soon as possible.

actually, now that I've thought about it, since subversion's whole 
repository is in one big bsddb file, you can't really separate them 
unless it is its own distinct repository (which may or may not be the 
route they choose).

In the case where it is its own distinct repository, you would probably 
want a regular copy of svnadmin dump (perhaps an incremental one, to be 
nice).

Maybe there are other replication solutions for svn, that will just use 
svn update to build a repository mirror (that preserves everything but 
subversion revision numbers, I guess)?

Would it be possible to host PyObjC there?

They do.

http://www.red-bean.com/people.html

Red-bean was created by a group of engineers because they needed a 
reliable set of hosting and server solutions that wouldn't change over 
time as their employment conditions changed.   The members of red-bean 
contain a good chunk of the apache crew, the subversion engineers, and 
contributors to apache, WebDAV (spec and implementation) and other 
critical bits of open source software.

Do they have an easy method for making backups of the repository? I 
have a daily backup of the CVS repository on my linux box at home, just 
in case SF screws up. If we'd move to red-bean.com I'd definitely want 
something simular.

I'm not entirely sure.  I believe that they are personal acquaintances

That should be easy enough, this is register_variableList in 
wrapper-const-table.h. This function whould have to be moved into the

As soon as possible, the only reason I haven't done a release yet is 
that the unittests cause a crash on 10.2. I checked in a change that 
might fix that, but I have not yet checked this.

[Pyobjc-dev] Mapping symbols from existing binaries

[Bob I. <bo...@re...>]

I think it's about time to start considering the ability to grab 
symbols from bundles and frameworks.  The particular use case I'm 
thinking of is extern constant NSStrings and integers, so we can make 
it more painless to wrap existing frameworks and defer more ObjC code 
to Python.

What kind of interface do you all think this should have?

This would be my proposal:
objc.loadSymbols(str moduleName, dict dictToUpdate str binaryPath, dict 
symbolNamesToSignatures) -> dict symbolNamesToObjects

It is a part of standard Cocoa.  Open up any random Cocoa App's wrapper 
and have a look at the Info.plist.  You will find an entry with a 
key/value pair like...

         <key>NSMainNibFile</key>
         <string>Edit</string>

... that, in this case, means that NSApplication will automatically 
load Edit.nib as a part of startup (the above came from 
TextEdit.app/Contents/Info.plist.

Document based apps do something similar, but there is a method that 
you can override on your NSDocument subclass to return the NIB name (or 
you can override -makeWindowControllers and set everything up by hand, 
if that floats your boat).

But that raises another question.  The above line works to unfreeze 
your second NIB file, but in all the example code, where is the first 
NIB file unfrozen, i.e. MainMenu.nib?  Is it hidden somewhere in
	AppHelper.runEventLoop(argv=[])

That won't work :-)

NibClassBuilder.extractClasses is a function that extracts class 
definitions from NIB files. That information is *only* used by 
NibClassBuilder.AutoBaseClass.

Neither, it is unfrozen by NSBundle.loadNibNamed_owner_

A slightly longer explanation...

You can define classes in Interface Builder (Classes -> Subclass 
<SomeClass>). Doesn't doesn't really define a class, but creates a note 
in the NIB file that the program that will load the NIB will contain a 
definition of the class. E.g. you promise IB that you will implement 
the class in your program.

IB can create empty Objective-C implementation files for the classes 
you "define" in IB, but that will overwrite any existing implementation 
files for those classes. These are not usefull for python anyway (wrong 
language).

You can use NibClassBuilder as a script and then it will behave the 
same as 'Classes -> Create Files for <SomeClass>' in Interface Builder.

This is useful for creating the initial (empty) implementation of 
classes, but cannot be used when you change the class in Interface 
Builder (add another action or outlet) because the script will always 
create an empty implementation (just like the Create Files command of 
IB). If you add a new outlet to the class you must therefore manually 
add this to your class definition.

This is where NibClassBuilder.AutoBaseClass and 
NibClassBuilder.extractClasses come into play. These two are used to 
extract information about the classes you declared in IB from the NIB 
file and automaticly add outlet definitions to your class. You must 
still add actions to your class, but you would have to do that anyway 
because the NIB doesn't contain imformation about the behaviour of the 
action.

Say to define MyController inside IB, with outlet myWindow and action 
myAction:.

	NibClassBuilder.extractClasses("MyNib")
	
	class MyController (NibClassBuilder.AutoBaseClass):

		def myAction_(self, sender):
			print self.myWindow


NibClassBuilder.AutoBaseClass is a magic base class that will look up 
'MyController' in the information extracted from the NIB file(s). It 
will then replace itself by the actual base class (as defined in the 
NIB) and add an outlet definition for the outlets.

You could also have written:

	class MyController (NSObject):
		myWindow = objc.IBOutlet("myWindow")

		def myAction_(self, sender):
			print self.myWindow


I hope this helps you understand what is going on,
