I download vim-fuzzyfinder into my downloads folder. I move the folder (containing autoload/, doc/, and plugin/ to ~/.vim/bundle/ (I'm using Pathogen, by the way). I start up vim and get the following error:
Error detected while processing /Users/archio/.vim/bundle/vim-fuzzyfinder/plugin/fuf.vim
line 13:
***** L9 library must be installed! *****
What happened? How can I get this to work? I'm fairly new to vim plugins.
The plugin in question appears to have a dependency on the L9 library, which I hadn't come across either so far. Just install the L9 library and retry.
Ah, and there is an alternative called the CtrlP plugin, and it is pretty good, especially, at least for me, when taking the fuzz out for straight matching as per the instructions given on the Vim mailing list archives in this MangoldSchinkenCannelloni message.
