Emacs Set Window to 80 Columns
When I'm coding, I maximize Emacs and enable
winner-mode, turning my display into something much
tiling window manager. Then I try not to leave Emacs until it's
necessary. It's a really nice way to work: no mouse touching needed.
At work they gave me a nice 24" monitor, 1920 pixels across. That's
just about enough to fit three Emacs' windows side-by-side at 78
columns each. The leftmost one contains my active work buffer where I
do most of my typing. The center one is usually split
horizontally. The top half is the
and the bottom half is either Emacs
calculator or an
*ansi-term* buffer. The rightmost
buffer contains something more static, like some sort of reference
However, I like my main editing window to be 80 columns wide. 78
columns cuts just too short. For awhile I was creating 80 dashes
C-u 80 -) and adjusting the window width manually to
size. After doing it a few times I decided to extend Emacs to do it
instead. First define a function to set the current window width.
Wrap it with an interactive function and bind it.
For those paying extra attention: instead of writing the extra
function, you could
expose function from
the other day.
The problem with this, though, is the dynamically generated function
doesn't have a name or a docstring. Someone
describe-key would have little information to go
