Hi group,
I was looking in "(elisp) Window Sizes" for a function to give me the
width of the text area of a window and found `window-body-width'.
However, this function gives me different results in terminal and GUI
modes, when linum-mode is enabled.
In terminal emacs, `window-body-width' includes the width of the line
number, while in gui emacs it doesn't. In both cases, the line number
width is returned correctly by `(window-margins)'.
So the question is: How can I get the width of the text-area (meaning,
in my case, without the line-numbers). I'd also like to avoid having to
distinguish X and terminal mode explicitly.
Thanks,
HP

Maybe try `(window-width)' ?

thanks to your report. It should exclude the display margins from the
width calculation on TTYs as well.

It's a bug in window-body-width, now fixed in the development sources,
