Subject: bug#17303: On tty or -nw, (window-body-width) is one column too big.
Date: Sun, 20 Apr 2014 17:03:43 +0000 [thread overview]
Message-ID: <20140420170343.GA4058@acm.acm> (raw)
Hi, Emacs.
I'm doing something at the moment involving scrolling of windows, and I
need to know at what "visual" column point is in. So, naturally, I do
(% (current-column) (window-body-width))
. At the start of the first continuation line, this formula (correctly)
returns 0 on a GUI, but (e.g.) 79 on a tty or in emacs -nw.
This is caused by emacs counting the "\" character in the right margin as
part of the body-width. This seems like a bad idea. I think it's also a
bug.
So, is there a better method of determining the "visual" column point is
in?
