After long struggles with HandOff (a.k.a. NSUserActivity), I have now 
established the fundamental theorem of HandOff:
It works, when it works.

With the corollary:
If not, then not.

Sometimes, when macOS refuses to see hand-offs from iOS, it helped to change 
the Bunde Identifier of the iOS app, thus tricking macOS into thinking it got 
something from an altogether different app.

But the more fundamental question:
Is it possible to do HandOff from macOS to iOS (without iCloud, sharing 
documents etc.), just like one can do HandOff from iOS to macOS (using the 
userInfo to communicate some small data)?

I tend to think this is impossible.
Any proof to the contrary would be most welcome.

Is there anybody on this list actually using HandOff?

Gerriet.

Are you sure you're just not seeing them because the text in some columns is 
longer than you tab width? 

I just made a simple example with this:

NSMutableAttributedString *mas = [[NSMutableAttributedString alloc] 
initWithString:@"\t1\t2\t3\t4\t5\t6\t7\t8\t9\t10\t11\t12\t13\t14\t15\t16\t17\t18\t19\t20\t21\t22\t23\t24\t25\t26\t27\t28\t29\t30"];
NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
NSMutableArray* ma=[NSMutableArray array];
for (int t=0; t< 31; t++) {
[ma addObject:[[NSTextTab alloc] initWithType:NSLeftTabStopType 
location:t*28.0f]];
}
[style setTabStops:ma];
[mas addAttribute:NSParagraphStyleAttributeName value:style 
range:NSMakeRange(0,mas.length)];
[self.textView insertText:mas];

It works as expected.

Re: Getting/Setting FinderInfo attributes using native Cocoa API?

2016-10-14 Thread Stephane Sudre 
I ended up writing a category for NSManager to deal with this using
the xattr.h APIs.

Something like:

- (NSDictionary *)PKG_extendedAttributesOfItemAtPath:(NSString
*)inPath error:(NSError *__autoreleasing *)outError;
- (BOOL)PKG_setExtendedAttributes:(NSDictionary *)inExtendedAttributes
ofItemAtPath:(NSString *)inPath error:(NSError *__autoreleasing
*)outError;

 Question:

 Is there a native Cocoa API that can replace the
 FSGetCatalog/FSSetCatalog API when it comes to retrieving/setting the
 FinderInfo (and FinderExtInfo) attributes of a file?

 OS X 10.8 and later.

 Problem:

 The FS CoreCarbon APIs are deprecated but apparently, there's nothing
 to replace them completely in Cocoa (Foundation).

 The NSURL resources APIs does not support the FinderInfo attributes
 (no obvious key in the broken documentation and using
 "com.apple.FinderInfo" does not work).


 Workaround:

 This can be worked around by using the xattr.h APIs but if it could be
 possible to avoid this, it would be better.

Xcode pretty heavily customizes the Cocoa text engine; even back in the 
ProjectBuilder days they had a bunch of custom editing subclasses. I wouldn’t 
be surprised if they implement their own tabbing for efficiency, since 
obviously the docs it works with include a bazillion tab stops.

Text Wrangler doesn’t use Cocoa’s text system at all. It’s a variant of BBEdit, 
which has been around since the early ‘90s so it must have its own text engine.

I’m surprised that there would be some arbitrary limit like 12 tab stops on a 
line. That sounds like something to file a bug report about. All they need is 
to change “kMaxTabStopsPerLine” to a bigger number like 100, right? :-p

NSTextView tab stop count

2016-10-14 Thread tridiak 
Why can’t I use more than 12 tab stops in NSTextView (enclosed by a standard 
NSScrollView)?
I can use less, but I need significantly more.
Is it to do with the ruler?

NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
NSMutableArray* ma=[NSMutableArray array];
for (int t=0; t< some large number; t++) {
[ma addObject:[[NSTextTab alloc] initWithType:NSLeftTabStopType 
location:t*28.0f]];
}
[style setTabStops:ma];
[mas addAttribute:NSParagraphStyleAttributeName value:style 
range:{0,mas.length}];

This works up to 12. Above that, it sticks to 12.

Applying something similar directly to the NSTextView paragraph style has the 
same problem.

How does Xcode & Text Wrangler pull it off?

TIA
Mark

Re: Font alignment when using bold variant of system font

2016-10-14 Thread Samuel Williams 
Just in case anyone finds this thread and wonders what the solution was,
here it is:

- (void) updateEditorHighlighting: (NSString*)expression

{

NSTextView * editor = (NSTextView*)[self currentEditor];


[self updateExpressionValue:self.stringValue into:editor.textStorage];


// This fixes a strange issue where the vertical alignment of the font is a
bit strange during editing.

NSMutableParagraphStyle * paragraphStyle = [[NSMutableParagraphStyle alloc]
init];

paragraphStyle.maximumLineHeight = [editor.layoutManager
defaultLineHeightForFont:self.font];


[editor.textStorage addAttribute:NSParagraphStyleAttributeName
value:paragraphStyle
range:NSMakeRange(0, editor.textStorage.length)];

}
