Hi,
I have gVim 7.4 on Windows 7 working perfectly.
I write a lot of SQLs code and I need some easy way to comment portion of my
code and remove comment after I debug the code.
I have found outstanding superb Vim commentary.vim plugin that actually adds
new operator "gc". Using this new operator I can combine it with motion, so
operator+motion and I can use for example:
gcc to comment out current line
gcG to comment out from current line to end of buffer
gcgg to comment out from current line to start of buffer
gcap to comment out a paragraph
V{some movement}gc to comment out selected lines
gc3j comment out current line and additional three lines bellow
Note: I was telling you superb idea to use operator-pending mode to get a new
operator.
I did the following:
1. Downloaded file
https://github.com/tpope/vim-commentary/blob/master/plugin/commentary.vim to
some location on my local disk.
2. Started gVim and sourced the file with: source commentary.vim
3. To comment out a line just use: gcc
Script works perfectly.
The script default comment string is:
*/ some text */
but I need:
-- some text
According to FAQ https://github.com/tpope/vim-commentary commentary string can
be changed using:
autocmd FileType apache setlocal commentstring=#\ %s
I have changed above command to my needs:
autocmd FileType sql setlocal commentstring=--\ %s
Now when I save a buffer with:
:w test.sql
and then execute for example gcc to comment out a line, scripts works fine it
adds -- at the beginning of line.
So far everything is OK, but now I have the following new wish:
I would ALSO like to enable comment string "--" when new buffer is created (but
obviously not saved yet, if it was above autocmd would be fired).
I have read the following excellent tutorial:
http://learnvimscriptthehardway.stevelosh.com/chapters/12.html and I tried to
use the following command:
:autocmd BufNew * setlocal commentstring=--\ %s
Then opened a new buffer:
:enew
and try to comment out a line:
gcc
and line is commented out with /* some text */ which is default comment string,
but I expected to get: -- some text
If I check the local variable:
:setlocal commentstring?
and the output is:
commentstring=/*%s*/
but I expected to be:
commentstring=--\ %s
It looks like my autocmd command was no fired or something override my autocmd.
If I manually set the string to
setlocal commentstring=--\ %s
and then command
gcc
works fine it comments out a line with prefixing it with:
-- some text
Now my question. How to set local variable to:
setlocal commentstring=--\ %s
when new buffer is created?
Thanks
