I like that the long lines are displayed over more than one terminal line; I don’t like that vim inserts newlines into my actual text. Which part of .vimrc I should change?
Answer
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).
