Hi, I'm working on a NSTextView, with Syntax Highlighting, and have got it working pretty well, my problem however is when editing in the TextView and press return in middle of a line only the previous line is re-styled, and the current line is'nt,
My question is how can I extend the range to restyle both.
Any help will be appreciated.
Further Detail:
Say I have the text
which is styled by the highlighter by matching the _* and the *_, styles them and text inbetween bold, italic and red
If I place cursor between the 'a' and 'n' of the word 'and' and then press return, breaking it onto two lines, the front half gets reset to unstyled text, whereas the 'nd Italics*_' loses the bold and italic styling, but stays red.
If I then press space and delete then that would also reset to unstyled text
The top of my processEditing is as follows
I then loop through a series of pre-made regexes which styles the edited text.
What I don't get is why the second half loses the bold and italic but stays red, why don't all three get reset?
