line-number-display-limit-width

line-number-display-limit-width

[stephenb]

using emacs 21.3 on windows:

the help file claims I can set var "line-number-display-limit-width", but
there is no such variable.
direct editing produces no match and browsing the "Display" group also does
not show such a variable.

do I need to setup that variable?
I saw the linum.el, but it displays line numbers in the buffer instead of
the mode line at the bottom.

Thanks everybody.

I'm using 22.1, and here's what's in my ~/.emacs:

(setq line-number-display-limit-width 1024)

With Emacs 21.3 typing C-h v RET line-number-display-limit-width RET
should give you

line-number-display-limit-width's value is 200

Documentation:
*Maximum line width (in characters) for line number display.
If the average length of the lines near point is bigger than this, then the
line number may be omitted from the mode line.

Only if computing the line-number slows down Emacs.  With Emacs 22.1
this variable is customizable.

Indeed.  linum.el is not related to this.
