Subject: 24.3; *grep* fails to display line numbers with global-linum-mode
Date: Fri, 29 Nov 2013 17:13:22 -0800

The following should produce a *grep* buffer:

    emacs -q
    M-x global-linum-mode
    ^x^f ~
    M-x grep
    a *

Note that only the first four lines of the *grep* buffer have line
numbers when all the visible lines should have line numbers.  Switching
to the new *grep* buffer dones make the line numbers appear.

Indeed linum.el suffers from various corner case problems.  Maybe this
one is fixed in Emacs trunk, or maybe it can be fixed.  But the
implementation technique used by linum.el has proved over the years to
lead to many such corner case issues.

I suggest you try out nlinum.el (available in GNU ELPA) which provides
basically the same functionality as linum.el but using a different
implementation approach, which is more robust.

    Very nice!  Does not suffer from this bug.  I will play with it
more.  Add the following in order to get a global mode:

(define-globalized-minor-mode global-nlinum-mode nlinum-mode nlinum-on)

(defun nlinum-on ()
  (unless (minibufferp)
    (nlinum-mode 1)))

So the solution here was to use nlinum instead of linum.  We now also
have display-numbers-mode.

Since there also have been no further updates here within 6 years, I'm
closing this bug now.
