vim E-117 unknown function pumvisible

[serpro69]

I have the following in my vimrc:

✓ ~→ grep -e "pumvisible" ~/.vimrc

inoremap <expr> <CR> pumvisible() ? "\<C-y>" : "\<C-g>u\<CR>"
inoremap <expr> <C-n> pumvisible() ? '<C-n>' : '<C-n><C-r>=pumvisible() ? "\<lt>Down>" : ""<CR>'
inoremap <expr> <M-,> pumvisible() ? '<C-n>' : '<C-x><C-o><C-n><C-p><C-r>=pumvisible() ? "\<lt>Down>" : ""<CR>'

After upgrading to 1.8.0 I can't use "Enter" key in insert mode anymore, and getting vim E-117 unknown function pumvisible error.

Anyone can suggest how I could fix this without modifying .vimrc? Maybe through .ideavimrc?

IdeaVim supports mappings with expressions since 1.7.0, so the line is no longer ignored
You can add iunmap <CR> to your .ideavimrc (after the line where you source your .vimrc) or create an IDE-specific vimrc (it's a new feature and it's kinda cool) https://github.com/JetBrains/ideavim#ide-specific-options

p.s. now parsing speed is ok, but if you put ideaVim ignore comment in the else block of your vimrc you can make your IDE to startup even faster

if has('ide')
  ...
else
  " ideaVim ignore
    ... your config for vim/nvim
  " ideaVim ignore end
endif
