[implementations-list] Visual region (was: vimpulse)

Wed Jul 1 16:17:54 CEST 2009

Hi Jason :)
Didn't you already talk with Michael Kifer times ago? I remember he said
something like not being interested in vim keybindings, but maybe I remember
wrong.
I tried to follow the 'y,'z path, and still I had to redefine yet another
viper function. It works like vim, except that instead of '< and '> it uses
'y and 'z. I'm feeling like entering kludge-world, and this is not a good
thing. Recognizing '< and '> would mean injecting even more kludges, and
directly modifying viper to be more vimpulse-friendly would mean:
a) injecting ugly kludges to make viper aware of my code (that's what has
been done redefining viper's functions btw)
b) refactoring viper to be more easily extended, and to be sure that the
refactoring doesn't break anything a better viper knowledge than mine is
needed I think.
I will think about it these days :) Meanwhile, suggestions on what to do are
welcome ^^
