I see that there is an attribute name (NSParagraphStyleAttributeName) for applying paragraph styles to text in Cocoa. Text is stored in an NSAttributedString, but what defines a "paragraph" in that string -- is it the newline character \n? Other characters? If it's a \n, then how do you create a new line without starting a new paragraph. And lastly, when you attach a ParagraphStyle to the string, do you have to use the exact range of the whole paragraph, or can you put it on any sub-range in the paragraph. If it can be a sub-range, how does the system handle two or more ParagraphStyles on the same paragraph?
thanks,

I got an answer from Douglas on Apple's cocoa-dev mailing list:
http://lists.apple.com/archives/Cocoa-dev/2010/Dec/msg00347.html
I'll copy what he wrote here:
Any of the standard paragraph separators can be used (\n, \r, \r\n, Unicode paragraph separator). Use the Unicode line separator character to start a new line without a paragraph break. It is best to apply a paragraph style to an entire paragraph; if that is not done, then the paragraph style attribute will be automatically fixed at attribute fixing time so that it is constant over each paragraph range, because that is needed at layout time.
It might be worth mentioning that Apple's String Programming Guide has a section on Paragraph and Line Breaks, and that NSString will give you the paragraph ranges without your having to search for paragraph separators.
the best way in iOS from my experience is to use
#"\n\r";
i found inconsistent behaviour with just using \n or even 0x2029 (which should be the equivalent of NSParagraphSeparatorCharacter (not defined in iOS))
the problems emerged when using NSAttributedString and NSParagraphStyle... as when using the #"\n" or (0x2029) the setParagraphSpacing was ignored by other than the first paragraph... using #"\n\r" got the paragraphes right

I used custom renderer to display a Label as RichTextBlock. Using Paragraph, there is a TextIndentProperty to indent first line. However, I also need "Hanging Indentation" found in RichEditBox or SetIndent found in ITextParagraphFormat.
Is there a way to implemnent "Hanging Indentation" in RichTextBlock?
I have found the solution to this question.
Use left-padding to shift the entire paragraph in (say 10px)
Then, use text-indent with negative value to shift the first line of the paragraph out again (say -10px).
With this method, a hanging indentation can be achieved.
Very close to reverse of this question. I prefer coding with 2-whitespace indentation, but need to have files indented with tabs to align with project convention. What I would like to do is preferably automatically convert 2 spaces upon entry to tab symbol in Notepad++ and have the editor configured to tab length of 2.
A possible manual way for doing this could be Edit->Blank Operations->Space to TAB but this converts all of my spaces to tabs, even those of length 1 - which are, for example, spaces between function arguments, not just leading spaces.
In a perfect case scenario I'm trying to achieve formatting style as described in this question, but with typing just spaces and the editor taking care of the rest.
I'm on Notepad++ 6.0, but willing to upgrade if this helps
Let me complete the answer of Ari Okkonen to add a workaround to the problem commented by Sergii Zaskaleta of mixed tabs and spaces at the beginning of the line.
Settings->Preferences->Tab Settings->Tab size: 2 (if not already)
Edit->Blank Operations->Space to TAB (Leading)
Select a block of lines of text with the problem of mixed spaces and tabs. Press [Tab] and [Shift]+[Tab] to add and remove a tab from each line. In the process, the leading spaces had been converted to tabs.
A manual way that seems to work: After having edited the file before saving you may try (Works in Notepad++ v6.8.3):
Settings->Preferences->Tab Settings->Tab size: 2 (if not already)
Edit->Blank Operations->Space to TAB (Leading)
When I'm using ShowText's whitespace (spacebar spaces) (in Block Composer), it only works in middle of the texts but not at the beginning of the text. I assumed it is because PDFClown do trim the whitespace characters.
So is there special character I can use in place of whitespace so it won't get trimmed?
Yes, leading whitespace is purposely trimmed off: if you need to indent your paragraph then use the BlockComposer.ShowBreak(SizeF) method specifying a horizontal offset (for example blockComposer.ShowBreak(new SizeF(10,0))).
I have a bulleted list in InDesign but I want the bullet character to be shown twice.
I'm using the / character, so I want it to appear like // like a comment. I can't figure it out. I have the bullet a different colour/style as the text following it, so I don't want to "hard-code" it in either.
Sorry for the trolls fellow. Your question isn't a programming question, which is why you got a downvote.
However, to help you out, try using a font for your bullet point that has a glyph that you like - you can use any character for the bullets, you know.
Or, if you create a new paragraph style, you can go into the Paragraph Style Options under Bullets and Numbering. Now, where it says Text After you can enter another bullet character there. But you'll have to also create a character style to set it to the right font to show your bullet character.
I've been playing around with NSTextView and have applied some paragraph styles to certain lines. However, when I type enter and get a new line, the attributes that I applied to one line are bleeding into the next.
I want to be able to apply a paragraph style to one line and have the next line be formatted in the default way. You can see what I mean from the screenshots.
When I add some spacing between paragraphs via NSParagraphStyle, the same spacing applies to the newline, which makes the whole thing look pretty shotty. Basically, I am looking for a way to reset the paragraph style for an empty line.
I have tried [MyTextView resetTypingAttributes:theAttributes] to no avail, since you first have to start typing for the new attributes to apply. Just to be clear, the line below the text in the screenshot is the cursor, which is really far down there as a result of the paragraph spacing.
Screenshot:
It seems that you have to use setTypingAttributes on the textview.
