Hi all This regexp seems to break ruby-mode parser or something like that (I’m not an advanced emacs user) This is the code: def image\_data src = open(“[http://www.dilbert.com/](http://www.dilbert.com/)”).read soup = BeautifulSoup.new(src) url = soup.find(‘img’, { :attrs =\> { ‘alt’ =\> /Today’s Comic/ } }) open(“[http://www.dilbert.com](http://www.dilbert.com)” + url[‘src’], “rb”).read end I’d appreciate if someone else tried this too. I’m using last version of ruby-mode.el and Gnu Emacs 22.0.92.1 Cheers -Weber ---

It buggers up Vim’s syntax highlighting as well, not sure how best to fix it, but there is a work-around, the %r{} construct: def image\_data src = open(“[http://www.dilbert.com/](http://www.dilbert.com/)”).read soup = BeautifulSoup.new(src) url = soup.find(‘img’, { :attrs =\> { ‘alt’ =\> %r{Today’s Comic} } }) open(“[http://www.dilbert.com](http://www.dilbert.com)” + url[‘src’], “rb”).read end Jason ---

I don’t see anything wrong - at least still sets the indentation correctly. An obvious guess is that the “'” character is the problem. Try escaping it: " /Today's Comic/ ". Of course I can’t test this fix as I don’t see the problem! > I’d appreciate if someone else tried this too.
