How to wrap up

[Ajay Jain]

Hi,

When I write a C code, I would like to wrap up after say 80 columns. Can
I do this in Vim? If yes, how? What are the related and useful commands
to wrap around while coding?

Regs,
Ajay.

Make sure 't' is in formatoptions to wrap code and not just comments:

:set fo+=t

and set textwidth to 80

:set tw=80

are the main two.

:help 'fo'
:help fo-table
:help 'tw'

You'll probably also want auto-indenting of some kind turned on.

:filetype indent on

may well suit you. If not, just

:set autoindent

:help :filetype-indent-on
:help 'ai'

The gq command is helpful for rewrapping stuff that's already written. I
tend to use linewise visual mode (shift-V) to highlight lines and then
type gq.

:help gq
:help v_q

Others may have more tips. There are so many...

Ben.

Hi,

:help wrap

eventually leads to 'textwidth', press <Ctrl>] to go to that help page.

so

:set textwidth=80

will set the maximum textwidth.

When you re-edit the already wrapped lines, visually select (press 'V')
the lines you want to reformat and hit gq (or just use gq$ to format
till the end of the line).

The others have given you an answer, but I personally don't like my
code to auto-wrap (though I love that my comments do so).

Instead, I highlight any text after a certain line length, so that I
know I should probably shorten the line somehow:

Mark the lines you want to wrap (with Shift-V or any other of the
v-commands), then type "!fmt<CR>"
