OK, let's say I have a brand new NSMutableAttributedString...

NSMutableAttributedString *mutAttribString;

Now if you look at NSAttributedString Additions, you'll notice an initWithHTML:documentAttributes: method. Well I want to create an NSMutableAttributedString.. and then later on.. feed it some HTML. But if you notice, there's no setHTML: method in NSMutableAttributedString. So what am I to do? Is this an oversite? Am I looking in the wrong place? Also, I -cannot- use the initWithHTML method because I am trying to get this called from an AppleScript Studio app.. and it doesn't like initializing through the call method command. If you aren't familiar with AS-S, then ignore the last line, it isn't relevant.. except that I can't use the initWithHTML method.

Thanks a lot for any help

P.S. Note that all of these things are in AppKit not Foundation if you want to reference the documentation...

If the problem is that calling -init doesn't work with that command, why not just create a wrapper method that does it for you? Like so:
<blockquote>code:<hr /><pre style="font-size:x-small; font-family: monospace;">+ (NSAttributedString *)makeAttributedStringWithHTML

NSData *)data documentAttributes

NSDictionary **)docAttributes
{
return [[self alloc] initWithHTML:data documentAttributes:docAttributes];
}</pre><hr /></blockquote>And then call makeAttributedStringWithHTML to create your string.

And if you want to feed an attributed string some HTML later on...you could create one (using a method similar to the one above, assuming it works) and then insert the string where you want it.

I'm not really much of an ASS guy, so I really have no idea about its features or limitations, but just guessing from what you described, that sounds like what you want. Hopefully.

<blockquote>code:<hr /><pre style="font-size:x-small; font-family: monospace;"> set myAttrString to call method "alloc" of class "NSMutableAttributedString"
call method "initWithPath:documentAttributes:&quo t; of object myAttrString �
with parameters {"/Users/ibson/Desktop/Sample RTF File.rtf", null}
log (call method "string" of object myAttrString)</pre><hr /></blockquote>And it successfully logged the string contents of the RTF file. Could you please post exactly what code AS-S is refusing to use? Also, if you did include that wrapper file Chuckit posted, it would be compiled into your executable for your AS-S application--meaning no extra files would need to be downloaded. Hope this helps

Thanks for the suggestions, I'll have to try it out.. I'll get my code soon, my computer was out of commission for like 2 days.. it wouldn't even mount the HD..

OK.. it's this.. I can't figure out how to pass NSASCIIStringEncoding to dataUsingEncoding... Some things I've tried:

set myData to call method "dataUsingEncoding:" of object "test" with parameter "NSASCIIStringEncoding"

set myData to call method "dataUsingEncoding:" of object "test" with parameter (call method "NSASCIIStringEncoding" of class "NSStringEncoding")

set myData to call method "dataUsingEncoding:" of object "test" with parameter (class "NSStringEncoding")

etc.. Any ideas?

NSASCIIStringEncoding = 1

but this doesn't work:

set myAttrString to call method "alloc" of class "NSAttributedString"

set myData to call method "dataUsingEncoding:" of object "test" with parameter 1

set myHTMLAttr to call method "initWithHTML:documentAttributes:" of object myAttrString with parameters {myData, null}

<blockquote>code:<hr /><pre style="font-size:x-small; font-family: monospace;">log (call method "description" of object myData)</pre><hr /></blockquote>All your code looks OK, but there might be some funky this happening with the NSData object. If this doesn't work, then you may be forced to write an Obj-C wrapper like:
<blockquote>code:<hr /><pre style="font-size:x-small; font-family: monospace;">+ (NSAttributedString *)attributedStringWithHTML

NSString *)string
{
NSAttributedString *newString;
NSData *stringData;

stringData = [string dataUsingEncoding:NSASCIIStringEncoding];
newString = [[self alloc] initWithHTML:stringData documentAttributes:nil];

return [newString autorelease];
}</pre><hr /></blockquote>...and add that as a category to NSAttributedString. Hopefully it won't come to this, but it might. This is what happened when I began to program in AS-S: I ended up writing so many Obj-C methods to use toolbars, defaults, bundles, etc. that I just ended up programming in straight Obj-C, and I never turned back
