word wrap - vim command to restructure/force text to 80 columns -

I know that automatically set textwidth (such as) What I see is similar to some = (indent line command), but to wrap 80 In the case of usage sometimes you edit the text with text width and after wrapping in lines or wrapping / removing the text wrapped in a bad way.

Ideally, this command will completely reconstruct the selected lines and cut the long lines while adding the little ones. An example:

Long line is long!

After running the command (assuming the rap as 13 columns):

  The long line is long! Less  

If this is not true with the vim command, maybe there is a command line program that does it that I can pipe the input?

After searching, I found in this context that there are a few other options:

For Set textwidth 80, the file can be started with the beginning ( Ctrl - Home or gg ), And type gqg .

gqg formats the file starting with the current state and by the end of the file. It will automatically be included in consecutive lines when possible. You can place a blank line between the two rows if you do not want to include them together at all.
