slimv not loading on *.lisp files in vim

Question

I installed slimv.vim (first through yaourt on Archlinux and then through vimana) and via both methods, slimv.vim doesn't load when I open a lisp file. I've scoured google results for debugging help, and here's what I have checked so far:

• :scriptnames does not show slimv.vim, so it's not being loaded at all
• :filetype shows all options set to ON
• :set rtp? shows ~/.vim as the first entry
• vim was compiled with python, shows +python
• slimv.vim and related files are all in ~/.vim/ftplugin/
• :echo $HOME shows the correct home directory
• slimv.vim is of filetype=unix
• I've tried both with and without let g:slimv_python = 'python2' in .vimrc, as suggested by the AUR comments for slimv
• :messages shows nothing
• :set ft? shows that the file is recognized as lisp

I don't have any other plugins, so it's possible that this is a general vim issue and I can't tell. What should I try next?

Answer 1

It's difficult to say where your problem is exactly but first I would check that your filetype is recognized properly. :set ft? should output something like filetype=lisp

After that you could check :messages for any error messages.

Answer 2

Even if :filetype shows all options set to ON, maybe they are set too late (paredit.vim sets them), so I suggest to write this in your .vimrc:

filetype plugin on
filetype indent on

Also you can set verbose mode by running vim with the -V10 option:

vim -V10 test.lisp

This prints log info on the scripts searched and sourced.

Slimv comes with paredit.vim that is a general (not a filetype) plugin, so it should be loaded for all filetypes. Check if it is loaded via

:echo g:paredit_loaded

You may also want to try to install another vim plugin just to test if it's a general vim problem or something related to Slimv.

EDIT: filetype plugins either need to have the same name as the filetype itself (e.g. lisp.vim) or they need to reside in a subdirectory having the same name as the filetype. Slimv uses the latter logic, so make sure that there is a lisp subdirectory containing slimv-lisp.vim:

~/.vim/ftplugin/lisp/slimv-lisp.vim

Answer 3

I eventually fixed this issue by uninstalling slimv.vim and manually removing the file named lisp from ~/.vim/ftplugin/, then reinstalling with vimana. It's working great, now. Thanks for helping me through it!
