Thanks the idea is "when i'm in an environment like pspicture or  
tikzpicture" to have a commmand to compile only the code between

begin{tikzpicture}
.....
end{tikzpicture}

I know that is possible with emacs and this is very useful if you  
works with emacs, idem for listings.

Ruby is perhaps the best tool to make that like some examples in the  
LaTeX Bundle ? Perhaps you know an example more simple ?
