Question: The reason why I'm asking this, is because I'm coding in C++, in putty/ssh and I like the fact that I can code from pretty much everywhere without having to install anything.

So I'd like to have something that could help me debugging (viewing LIVE value of a variable, breakpoints, etc)

If you think that there's no such thing in this world, is there any good technique I could use to debug in command line?

Thanks

Answer: 
Have you tried `gdb` ? That's pretty much **the** command line debugger, but it's no vim plugin.
You have a script to do that: <http://www.vim.org/scripts/script.php?script_id=1954>

In my humble opinion, Vim is not designed to do such things and it is a bad idea to do so.
