Actually, I need a mix of both modes (I need to rub out keywords on a per-word basis, but let variables be corrected on a character granularity); so I won't be trivial, but far to be impossible.

It sounds like you want a launchd agent. launchd can launch your program when certain paths are modified, via the WatchPaths or QueueDirectories info plist keys. The advantage of this approach is that your process does not have to run continuously in the background: it's launched on-demand, and can exit when it's finished. -Peter ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Core Data : Managed Object Models : Configurations, Versions
In the Core Data Programming Guide > Managed Object Models, "A persistent store coordinator can only have one managed object model, so by default each store associated with a given coordinator must contain the same entities. To work around this restriction ... You typically use configurations ..." Well, I have a document-based Core Data app and would like to store some logging stuff in an sqlite store in ~/Application Support/MyApp/. The entities modelling the logging stuff are all different than the entities in the document's model. So, I believe I'm in the situation described above. Yes, it *seems like it would be inefficient* to add the logging entities to the existing managed object model. To me, the natural solution would be to create a whole new persistence stack based on another managed object model for my logging stuff. Yet the documentation seems to suggest that I instead pack the new entities into the existing managed object model and then segregate them using a "configuration". Am I reading this correctly? What is so bad about multiple managed object models that we invented "configurations" just to avoid them? But wait, a paradox ... There are five "Initializing" methods in NSManagedObjectModel. Four of them involve "merging" models, and indeed one of these is used in the Xcode Core Data non-document-based template project. Apparently it is common to "merge" managed object models. When is this done? My app's bundle contains three managed object models, but they are for versioning; a current version and two older versions. When I create an in-memory store for temporary manipulation, following that Xcode template code I create a managed object model using [NSManagedObjectModel mergedModelFromBundles:nil]. Eeek. Is this merging my old and current model versions? If so, why doesn't that give me "Can't merge models with same entities" errors? Would it be better to initialize this managed object model using only the current version, with -[NSManagedObjectModel initWithContentsOfURL:]? To do that I'd need to pass a file URL to the current model resource. Hard-coding that would be fragile. Core Data seems to have no problem identifying the current model resource, but an API for this seems conspicuously absent. How can I get the file URL of the *current* model resource?

Variable row heights were a late addition to NSTableView (added in > 10.3 or 10.4?) and I wouldn’t be surprised if they’re not optimized for huge > numbers of rows. The table view is optimized for a huge number of rows -- the implementation in 10.3-10.6 uses a sparse array of row heights, and attempts to lump together equal row heights into a single bucket. This makes it quite fast at computations. Having a lot of non-equal row heights will be more expensive (there is no way around that) as each rowRect computation needs to figure out where to be. Even though it is fast, however, a table with 200,000 rows is excessive. There is no way a user can realistically use all those rows without some sort of filtering/searching. I would consider re-doing your UI to have a "more results" button, akin to the Finder spotlight search results.

After calling that method, the said indexes can return a new height. Not doing this will cause the types of problems that you see, as the table may (or may not) cache every row height, and expects the same result to be returned for the same row every time (until it was told it changed). Sending the node in some sort of bounds changed notification should be fine -- the problem you are encountering is probably because you are breaking the above rule mentioned. Do the height calculations in the bounds change, and then call the "noteHeight.." method all in the same run loop stack; that will probably fix your problem. corbin ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Variable row heights were a late addition to NSTableView (added in 10.3 or 10.4?) and I wouldn’t be surprised if they’re not optimized for huge numbers of rows.

Possibly NSTableView needs to know the height of all preceding rows in order to calculate the position of a given row? You may need to compromise your requirements, or else consider making your own custom view which can "draw smarter". But this may not be practical since NSTableView provides a *lot* of behavior you might still need, meaning you'd be discovering little issues and writing code for weeks. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Look in your project and change that framework to the one you actually want to use. You can use ‘otool’ to examine the library paths compiled into the binary. —Jens___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Locating Frameworks
That didn't do much for me.
It seems that the /Library/Frameworks path is overwritten at runtime by its the
second in line /System/Library/Frameworks.

Try calling Py_SetProgramName() before Py_Initialize()
NSString *launchPath =
@"/Library/Frameworks/Python.framework/versions/current/bin/python";
Py_SetProgramName((char *)[launchPath UTF8String]);

Locating Frameworks
Hi,
I am trying to link to the Python.framework.
According to the manpages the framework directories are searched in the
following order:
"The default framework search path is /Library/Frameworks then
/System/Library/Frameworks."
Running my code:
Py_Initialize();
PyRun_SimpleString("import sys\n"
"print('Version: ', sys.version)\n");
Py_Finalize();
Shows the following:
('Version: ', '2.6.1 (r261:67515, Feb 11 2010, 00:51:29) \n[GCC 4.2.1 (Apple
Inc. build 5646)]')
But I have Python 3.1.2 installed in the /Library/Frameworks path, shouldn't
this library be used and result in the following version info ?
'3.1.2 (r312:79360M, Mar 24 2010, 01:33:18) \n[GCC 4.0.1 (Apple Inc. build
5493)]'
So my question is the following: How do I force the linking with the Python
3.1.2 version (or highest version installed)?
Thanks,
Filip

Re: Custom NSCell mouse events
Thanks for the suggestion Corbin. It looks like I'm doing everything
OK with creation and destruction though. Here is my code:
- (id)init {
if ((self = [super init])) {
_checkboxCell = [[NSButtonCell alloc] init];
[_checkboxCell setButtonType:NSSwitchButton];
[_checkboxCell setTitle:@""];
[_checkboxCell setTarget:self];
[_checkboxCell setImagePosition:NSImageLeft];
[_checkboxCell setControlSize:NSRegularControlSize];
}
return self;
}
- copyWithZone:(NSZone *)zone {
MyCheckboxCellToo *cell = (MyCheckboxCellToo *)[super copyWithZone:zone];
cell->_checkboxCell = [_checkboxCell copyWithZone:zone];
return cell;
}
- (void)dealloc {
[_checkboxCell release];
[super dealloc];
}

Where to noteHeightOfRowsWithIndexesChanged
Where's the best place to put noteHeightOfRowsWithIndexesChanged to keep a tableview display correct whilst scrolling? The tableview has variable height rows, and because of a relatively slow data source, resizing and user control of fonts, etc, I don't know the row height in advance. I'm caching the row height, and returning a single-line height if the row is not visible (and the height is not yet known). If the row is visible I calculate the actual height and return that (via the NSTableView heightOfRow delegate). This almost works, but I've not found a good place to put noteHeightOfRowsWithIndexesChanged. I get either overlapping rows or some blank rows during scroll. I've tried NSViewBoundsDidChangeNotification. I've even tried putting it in the heightOfRow delegate (which I know must be wrong), with some re- entrancy control which has given the best results so far (but still displays blank rows sometimes). There are usually about 200,000 rows, so calculating the actual height for all rows is not an option (since it takes about 19 seconds). Any ideas anyone?
