Emacs: No Wrap Lines

make lines NOT soft-wrap

Alt+x toggle-truncate-lines

when on, lines runs off and disappears on the right window margin. You have to horizontal scroll right to see them.

Tip: This is useful when you just want to get an overview of lines.

Note: the command name is misleading. It doesn't really truncate. Proper name would be “toggle-line-softwrap”.

put this in your Emacs Init File:

;; make emacs not soft-wrap lines by default for all buffers
(setq-default truncate-lines t)
;; not recommended
;; if you do this, dired filenames or url may show at next line
