linum

And you can always temporarily enable linum-mode if you really need to see all of the line numbers.

Emacs 24 loaded with -Q (so no customizations are loaded) and linum enabled on a large file makes Emacs sluggish.

At least in my experience, linum makes Emacs 24 unusably slow to respond to typing.

Currently using Sony IER-M9 with a Linum DualBax Zebra, which is a great cable, btw.

I think I remember its presence having something to do with a conflict between fringe-mode and linum-format.

Looks like you want global-linum-mode to get line numbering.

I'm amazed linum is not more popular in that list (~10% usage)..

I definitely thought more people used linum than say something like winner.

You’re probably using the old notoriously slow linum-mode.

I found global-linum-mode to be rather slow in large files, unfortunately.

It would be better to show and hide linum with some simple binding, but I'm already used to them, so it's not a big deal for me.

A note: I' be careful though, because depending on how you create your variables, thing can go wrong, I guess: if you-re going to use eval-buffer on your whole.emacs, I'd better use, for example, add-hook instead to add-to-list: (add-hook c-mode-hook 'linum'mode) instead of: (add-to-list c-mode-hook 'linum-mode) Just saying.

I haven't fully isolated this to "linum" vs "linum and XXX together", but when linum-mode is enabled, Emacs is noticeably sluggish.

Try to determine which one you're using by running "M-x linum-mode" and then "M-x display-line-numbers-mode".

"Meanwhile", in recent Emacsen, what you want is linum-mode You can also customize this with M-x customize-group RET linum where you can set font, format for numbers and enable/disable line numbers globally.

I switched linum-format to " %d " and this is clearly better.

So, I made this little COM library (Linum) which would simply pre-allocate a buffer for writing into.
