vim - how do I prevent vim from auto-wrapping at column 80

Question

As I'm writing code, when the cursor reaches column 80, vim automatically wraps the text by inserting a newline character. How do I prevent vim from doing so? Is there any setting that am missing?

Answer 1

The auto-wrapping is defined by set wrap and this option depends on the width of your window/screen, but it does not insert a newline character into the file.

The column 80 is defined by set tw=80 this will change the text by adding new linebreaks for long lines.

To check details, you can:

:h 'wrap'
:h 'tw'

To disable auto-wrapping, you could:

:set nowrap

To disable long line auto broken, you can:

:set tw=0

0 is default.

Answer 2

Just found that set tw=0 works. It doesn't wrap lines by inserting a new line character at a predefined limit.

Added that set to vimrc to make it permanent.
