Blog APIs

It can be quite annoying when an application claims to support an API and actually doesn’t ūüôĀ 
I’ve been working on BlogThing off an on for about a week or so. Originally I used a bit of the metaWeblog API and a bit of the MovableType API. I’ve since standardized on metaWeblog and removed the references to MovableType. ūüôā 
Now, I’ve successfully tested BlogThing against WordPress and Typo however, Blojsom, while it claims to support the metaWeblog API it soon becomes apparent that this is not the case ūüôĀ

Accessing the string and attribute data in a NSTextView

NSTextView stores its data in a NSTextStorage object. NSTextStorage descends from NSMutableAttributed string, so that gives us a clue. 
The easiest thing to do is to make a category on the NSAttributedString class to do whatever it is you want containing something like the following. 
    NSRange range; 
int i; 
int L = [self length]; 
    i =
while(i<L) { 
// get all the attributes we are interested in 
        NSDictionary* attributes = [
self attributesAtIndex: i effectiveRange: &range]; 
        NSAttributedString* attPart = [
self attributedSubstringFromRange: range]; 
        NSString* part = [attPart string]; 
        NSFont* font = [attributes objectForKey: NSFontAttributeName]; 
        NSColor* color = [attributes objectForKey:
        NSParagraphStyle* paraStyle = [attributes objectForKey: NSParagraphStyleAttributeName]; 
        NSShadow* shadow = [attributes objectForKey: NSShadowAttributeName]; 
        NSURL* link = [attributes objectForKey: NSLinkAttributeName]; 
        NSTextAttachment* attachment = [attributes objectForKey: NSAttachmentAttributeName]; 
// process your attributed string pieces here 
        i = range.location+range.length;
