Wrap line/text in org-mode when I re-open a file

Question

I run emacs 24.5 and word/line wrap works fine when I write new text. However, when I reopen an org file, the text is not wrapped. This makes it hard to read text I have written before. Is there a setting or something that I can change to fix this?

Answer 1

You can set the variable org-startup-truncated. Its documentation:

Non-nil means entering Org-mode will set ‘truncate-lines’. This is useful since some lines containing links can be very long and uninteresting. Also tables look terrible when wrapped.

So if we don't want to truncate lines, we need to set it to nil:

(setq org-startup-truncated nil)

After this, lines will wrap. However, this is soft wrapping; it doesn't insert newlines into the text, just shows the text as though it wraps. This is probably what you want; newlines in titles won't really work for other things in org.
