Completion not triggered even when a list is returned

[sriramkswamy]

I was trying to use this with auto completion enabled and trying to complete the world tolerance in one of my files but I got this instead

tpumvisible()?mucomplete#yup():''

'

and was put in the command line with an =.

Here's a small gif that explains what I'm trying to tell - vim-mucomplete

That GIF shows the file I'm trying to invoke mucomplete from. I have also tried disabling auto completion and evoking it manually. It didn't work either.

Here's my mucomplete settings.

Plug 'lifepillar/vim-mucomplete'
let g:mucomplete#no_mappings = 0
let g:mucomplete#auto_select = 0
let g:mucomplete#enable_auto_at_startup = 1
let g:mucomplete#exit_ctrlx_keys = "\<c-b>\<bs>"
let g:mucomplete#chains = {}
let g:mucomplete#chains.default = ['file', 'c-p']
let g:mucomplete#chains.markdown = ['keyn', 'spel', 'dict']
let g:mucomplete#chains.tex = ['omni', 'c-p', 'spel', 'dict']
let g:mucomplete#chains.vim = ['omni', 'cmd', 'file', 'c-p']
let g:mucomplete#chains.c = ['omni', 'tags', 'file', 'c-p']
let g:mucomplete#chains.cpp = ['omni', 'tags', 'file', 'c-p']
let g:mucomplete#chains.py = ['omni', 'tags', 'file', 'c-p']
let g:mucomplete#chains.java = ['omni', 'user', 'tags', 'file', 'c-p']
let g:mucomplete#chains.r = ['omni', 'tags', 'file', 'c-p']
let g:mucomplete#chains.ruby = ['omni', 'tags', 'file', 'c-p']
let g:mucomplete#chains.matlab = ['omni', 'file', 'c-p']
let g:mucomplete#exit_ctrlx_keys = "\<c-c>\<bs>"

I think it satisfies all requirements.

[lifepillar]

Try to remove this line:

let g:mucomplete#exit_ctrlx_keys = "\<c-c>\<bs>"

Also, what is the output of: :imap <c-b> and :imap <c-r>? If you get something different from No mapping found, that's a problem.

[lifepillar]

Watched the asciicast, it looks like https://github.com/lifepillar/vim-mucomplete/issues/15. Do you have vim-peekaboo installed?

[sriramkswamy]

Yes, that was the problem. However, I have another question. When I try to write a word that is not in the auto completion list yet, it automatically deletes the last character that doesn't comply with that list. Is there a way to avoid this behavior?

For example, if I try to type install when the completion popups with insert and ins, it deletes the t character and leaves insall when I'm typing fast. Is this normal?

[lifepillar]

For example, if I try to type install when the completion popups with insert and ins, it deletes the t character and leaves insall when I'm typing fast. Is this normal?

Definitely not. But I cannot reproduce that problem. Please try with the following minimal vimrc_minimal:

set runtimepath+=/path/to/mucomplete/
set completeopt-=longest
set completeopt+=menu,menuone

Then:

vim -N -u vimrc_minimal

Let me know if you still see the problem.

[sriramkswamy]

I see that it works correctly with the minimal vimrc. I'm not sure what the problem is. I'll figure it out. Probably something to do with my config.
