how to stop line breaking in vim

Question

I'm editing some file with extreamly long line in it. My current vim settings will wrap thoes long lines but breaking them at the same time. It's good to see that a very long line is wrapped but it's not very apeal to me that a very long line is broken to more than one line .So what I need is : let vim wrap a long line but without line breaking . I know all the magic is in .vimrc, so put the question in another way : which part of .vimrc I should change ?

============================================================================================== there are lots of complain that I don't put my question clearly . I agree and thank you for remind. Stolen from andrew comments , put my question in a more clear way : I'd like that the long lines are displayed over more than one terminal line; I don't like that vim inserts newlines into your actual text .

Answer 1

Use

:set wrap

To wrap lines visually, i.e. the line is still one line of text, but Vim displays it on multiple lines.

Use

:set nowrap

To display long lines as just one line (i.e. you have to scroll horizontally to see the entire line).

Answer 2

I'm not sure I understand completely, but you might be looking for the 'formatoptions' configuration setting. Try something like :set formatoptions-=t. The t option will insert line breaks to make text wrap at the width set by textwidth. You can also put this command in your .vimrc, just remove the colon (:).

Answer 3

Here's what you want:

" this enables "visual" wrapping
set wrap

" this turns off physical line wrapping (ie: automatic insertion of newlines)
set textwidth=0 wrapmargin=0

Answer 4

Use :set nowrap .. works like a charm!

Answer 5

:set tw=0

VIM won't auto-insert line breaks, but will keep line wrapping.

Answer 6

You may find set lbr useful; with set wrap on this will wrap but only cutting the line on whitespace and not in the middle of a word.

e.g.

without lbr the li
ne can be split on
a word

and

with lbr on the
line will be
split on 
whitespace only
