Hello All.
I have text in an NSTextView that I want to style with different
fonts and colours. Each paragraph begins with a paragraph number, for
example:
1 This is the first paragraph.
2 This is the next one.
3 Here's another and there are usually more.
I want to be able to pick out the numbers and style them in a
different font, size and color. I've got ARegEx in my app, and am
using it successfully to alter other parts of the text. I've also go
a loop going, using an NSScanner and searching for specific words so
I can style those as needed.
I know I can use NSRange to select text and style it, but I can't
work out how best to deal with this situation, where the source is
not a single word but different numbers. Apart from the first number,
all the others happen after a carriage return, so I'm looking for
that plus whatever the number/s are after it.
I guess I'm looking for a routine that can take a RegEx search string
(something like "\r[0-9]+") and return it's position and length as a
range. Am I asking for too much?..!
