One often has to restrict the column width to 80 or 75 or
whatever. One can set this quite easily by using the
command
To do this automatically just put the command in your .vimrc.
In addition to textwidth you may want the text to wrap at
a certain column. Often such choices are dictated by the
terminal one is using or it could just be by choice. The
command for such a case is
The above command makes the text wrap at 60 columns.
While coding in C, one often indents inner-blocks of
code. To do this automatically while coding, VIM has an
option called cindent. To set this, just use the command
By setting cindent, code is automatically beautified. To
set this command automatically, just add it to your .vimrc
VIM also allows you to auto-format comments. You can split
comments into 3 stages: The first part, the middle part
and the end part. For example your coding style
requirements may require comments to be in the following
style
/*
* This is the comment
*/
|
In such a case the following command can be used
:set comments=sl:/*,mb:*,elx:*/
|
Let me decipher the command for you. The commands has
three parts. The first part is sl:/*. This tells VIM that
three piece comments begin with /*. The next part tells
VIM that the middle part of the comment is *. The last
part of the command tells vim a couple of things. One that
the command should end with */ and that it should
automatically complete the comment when you hit just /.
Let me give another example. Lets say your coding
guidelines are as follows
/*
** This is the comment
*/
|
In such a situation you can use following command for comments
:set comments=sl:/*,mb:**,elx:*
|
to insert a comment just type /* and hit enter. The next line
will automatically contain the **. After you've finished
the comment just hit enter again and another ** will be
inserted. However to end the comment you want a */ and not
**/. VIM is quite clever here. You don't need to delete
the last * and replace it with /. Instead, just hit / and
VIM will recognise it as the end of the comment and will
automatically change the line from ** to */.
