E117: Unknown function: ale#Lint

Question

I try upgrading my .vimrc file. When I open up a Rails application I'm working on I get the following error.

rails_app/config/environments/development.rb                                                                    2,3            Top
Error detected while processing CursorHold Auto commands for "*":
E117: Unknown function: ale#Lint
Press ENTER or type command to continue

The error is thrown from Ale I guess from the following line.

" ALE linting events
augroup ale
  autocmd!

  if g:has_async
    set updatetime=1000
    let g:ale_lint_on_text_changed = 0
    autocmd CursorHold * call ale#Lint()
    autocmd CursorHoldI * call ale#Lint()
    autocmd InsertEnter * call ale#Lint()
    autocmd InsertLeave * call ale#Lint()
  else
    echoerr "The thoughtbot dotfiles require NeoVim or Vim 8"
  endif
augroup END

On the vimrc.bundles I have the following line.

if g:has_async
  Plug 'w0rp/ale'
endif

Is there a reason why ale is not being installed properly?

Answer 1

ale#Lint needs be replaced with ale#Queue(0)
