@cindex Set number capability in @code{vi} emulators
The @samp{linum} package (distributed with Emacs since version 23.1)
displays line numbers in the left margin, like the ``set number''
capability of @code{vi}. The packages @samp{setnu} and
@samp{wb-line-number} (not distributed with Emacs) also implement this
feature.
The @samp{display-line-numbers} package (added to Emacs in version
26.1) displays line numbers in the text area, before each line, like
the ``set number'' capability of @samp{vi}. Customize the
buffer-local variable @code{display-line-numbers} to activate this
optional display. Alternatively, you can use the
@code{display-line-numbers-mode} minor mode or the global
@code{global-display-line-numbers-mode}. When using these modes,
customize @code{display-line-numbers-type} with the same value as you
would use with @code{display-line-numbers}.
There is also the @samp{linum} package (distributed with Emacs since
version 23.1) which will henceforth become obsolete. Users and
developers are encouraged to use @samp{display-line-numbers} instead.
The packages @samp{setnu} and @samp{wb-line-number} (not distributed
with Emacs) also implement this feature.
