Bad syntax highlighting for function call in autocmd

[ddickstein]

• nvim --version: v0.5.0-dev+1268-g02909d150

Steps to reproduce using nvim -u NORC

Create a file foo.vim and type the following:

augroup Foo
  autocmd WinEnter * call abs(0)
augroup END

Actual behaviour

The function abs is highlighted as an error.

Expected behaviour

The syntax highlighting should not report an error. This is a regression since Neovim 0.4.2.

This doesn't happen in Vim and just copying runtime/syntax/vim.vim from Vim's repo to Neovim's fixes this problem, so it's just a matter of porting the runtime file.

[mhinz]

Either Nvim wasn't installed properly or you ran build/bin/nvim directly from the repo.

In the latter case and since we auto-generate the vim syntax file, you need to do this:

  if v:progpath =~# 'build/bin/nvim$'
    " for build/runtime/syntax/vim/generated.vim
    set runtimepath+=$VIM/build/runtime
  endif
