Hi,

I just started using the SimpleFold [1] plugin with vim 6.4.  
When I start vim I get the following error:

E518: Unknown option: completefunc=10\_RCT\_completion

My .vimrc contains  
map f SimpleFold\_Foldsearch  
" fold when switching to that buffer  
“au Filetype ruby call SimpleFold\_Foldsearch(”")

Question 1: What do I have to do to make that annoying error go away?

Question 2: If I uncomment the last line, the plugin should be used on  
each freshly loaded ruby file. However vim complains, that the plugin is  
unknown. How do I change that?

Happy rubying,  
Guido

This comes from the rcodetools plugin. completefunc was added in vim 7.0  
and  
isn’t thus available in 6.4. You can get rid of the error by commenting  
the  
corresponding line in ~/.vim/plugin/rcodetools.vim:

"execute “au Filetype ruby setlocal completefunc=” . s:sid .  
“RCT\_completion”

For the time being just edit rcodetools.vim; I’ll add some code to  
detect the  
vim version and skip the completefunc for vim \< 7.0 in the next release.

This should do (it works for me) if you’re using the f mapping.

" fold when loading Ruby files  
au Filetype ruby execute "normal " . mapleader .“f”

HTH,

Somehow this doesn’t work, vim complains that the variable mapleader is  
undefined. However it’s not much trouble to just press \f on loading, so  
maybe I’ll just go with that and hope I can get vim7 soon 🙂

Thanks!

Maybe an extra indirection level?  
execute “au Filetype ruby execute ‘normal " . mapleader . "f’”

works for me (but so does the above line, with vim 7)

Hello,  
My two cents. Install VIM 7.0.x. Here is a link that I followed  
without any problems. Works like a charm. I am assuming that you are  
on a linux/unix system?
