Subject: [sup-talk] Get text at current line in ThredViewMode

Hello Everybody,

I am attempting to do some hacking to get a custom Keymap working. I am
trying to figure our a way to get the text of the cursor line so I can
process it further.

I see the @message_lines but that just returns a message. From there I
cannot find how to get the actual text displayed. 

Is this even possible to do? What am I missing?

Thanks for your help.

Thanks Matthieu!

Ultimately that is what I was trying to do-open URI under cursor line.

I arrived at a similar solution. I will repost mine here, in case anyone
else finds it helpful.

class Redwood::ThreadViewMode
  def open_link_at_cursor
    BufferManager.flash "Extracting URL...#{'(turn text wrap off for better results)' if @wrap}"
    line_text = get_textline_at_cursor
    url = line_text.slice(URI::regexp)
    spawn "chromium","--new-window", url,[:in, :out, :err] => "/dev/null" unless !url
    BufferManager.flash "No URL found at cursor line" if !url
  end
  def get_textline_at_cursor
    self[curpos].last.last.to_s
  end
end
