You can use the
'formatoptions' option to influence how Vim formats text.
'formatoptions' is a string that can contain any of the letters below. The
default setting is
tcq. You can separate the option letters with commas for
Note that the statement about the "defaults" is somewhat misleading, since many filetypes change the formatoptions to best suit the file type; for example in
" Set 'formatoptions' to break comment lines but not other lines,
" and insert the comment leader when hitting <CR> or using "o".
setlocal fo-=t fo+=croql
You can view the current
And see where they were set like so:
:verbose set fo?

In this case, you want to remove the
r flag, but perhaps also the
r Automatically insert the current comment leader after hitting
<Enter> in Insert mode.
c Auto-wrap comments using textwidth, inserting the current comment
o Automatically insert the current comment leader after hitting 'o' or
'O' in Normal mode.
This can be done like so:
:set formatoptions-=r formatoptions-=c formatoptions-=o
Note that using
:set formatoptions-=cro won't work as expected (since it's a string, it will look for the string
cro, in that order, which often won't work.).
To set the changes only for the current buffer, use
:setlocal instead of
:set. If you want to always have these options, it's probably best to use an
autocmd in your vimrc; for example:
au FileType vim setlocal fo-=c fo-=r fo-=o
This will set the options only for the 'vim' filetype, and won't interfere with other filetypes.
If you want to always set it, use:
au FileType * set fo-=c fo-=r fo-=o
set fo-=cro won't work since many filetypes set/expand
formatoption (like shown above); the FileType autocmd is executed after the filetype files have loaded.
