svnsync example

it really works

first create a file pre-revprop-change including the following output by cat. And the file needs to be executable.
That is,

$chmod +x pre-revprop-change 


$ cat pre-revprop-change 
#!/bin/sh
exit 0


$ ls -Alh pre-revprop-change 
 -rwxr-xr-x  1 pmezard  staff    18B May 17 11:37 pre-revprop-change
$ svnadmin create repo
$ cp pre-revprop-change  repo/hooks/
$ svnsync init --username svnsync file://`pwd`/repo http://wub.googlecode.com/svn

working with long lines in vim

some are copied from http://vim.wikia.com/wiki/Best_Vim_Tips

When we have long lines in VIM and we set wrap option to make it a lone lines look like 

several lines in view.  But the moving across lines using jk are still on real lines. How to work around this? 

First, we can map like the following:

 noremap <C-J> gj noremap <C-K> gk 

That's really useful when dealing with long lines. It lets you use Control-J and Control-K to move up and down screen lines instead of buffer lines with j and k. Control-J isn't really mapped to anything by default, it's like hitting enter, but Control-K is something to do with digraphs. However, noremap won't remove this ability in insert mode.

Alternatively, you could use:

 noremap <Up> gk noremap <Down> gj
