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

[Micah Duke]

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.

Hello,

Take a look at this PR:

https://github.com/sup-heliotrope/sup/pull/241

In this PR I take the text on the current line, try to extract an URI
out of it and open it with the system's xdg-open. The line you're
interested in is thread_view_mobe.rb:718. Basically a view is a list of
tuples: [color, data]. color denotes how to paint the data. The one
you're interested in is certainly :text_color.

This PR really old, and I should work on it, but I got distracted ...

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
