I would like to try out the vmath.vim plugin which adds up columns of numbers. It is available at: https://docs.google.com/file/d/0Bx3f0gFZh5Jqc0MtcUstV3BKdTQ/edit?lsrp=1
I copied the vmath.vim file into my ~/.vim/plugin folder. I also added the following lines in my vimrc
vmap <expr> ++ VMATH_YankAndAnalyse()
nmap ++ vip++
But using ++ in normal mode or visual mode does not work. Am i supposed to somehow load the plugin before?
:scriptnames
? Also, does:echo loaded_vmath
give you1
