Doesn't start with init.lua

[augustebaum]

Describe the bug When I use init.vim the preview starts as normal, and when I use init.lua nothing starts, with no errors.

To Reproduce

1. Install vim-plug and paq.nvim (sorry, apparently one can't use vim-plug with init.lua so I had to change when I rewrote it).

2. Take

   " init.vim
   set nocp
   filetype plugin on
   let g:NVIM_PLUGINS_DIR = stdpath('config') . '/plugged'
   call plug#begin(NVIM_PLUGINS_DIR)
   Plug 'iamcco/markdown-preview.nvim', { 'do': 'cd app && yarn install' }
   call plug#end()

   and

   -- init.lua
   vim.o.cp = false
   vim.cmd("filetype plugin on")
   require "paq" {
   {"iamcco/markdown-preview.nvim", as="markdown-preview", run="cd app && yarn install" };
   }

   and install the plugin (with :PlugInstall for the first and :PaqInstall for the second).

3. Open some markdown file using nvim -u init.vim file.md. Run :MarkdownPreview. Works as expected (server starts at localhost, browser opens it).

4. Open the markdown file using nvim -u init.lua file.md. Run :MarkdownPreview. Nothing happens (and no errors). In particular, the server doesn't seem to have started (when I use the address I have when it works, I get "not found").

Expected behavior Everything works exactly the same for the two setups.

Desktop:

• OS: Mac OS X 10.14.6

Log:

checkhealth gives:

health#mkdp#check
========================================================================
  - INFO: Platform: macos
  - INFO: Nvim Version: NVIM v0.6.0-dev+9-g490615612

  - INFO: Script: std('data')/site/pack/paqs/start/markdown-preview/app/server.js
  - INFO: Script exists: 1

Otherwise the plugin has been working great, thanks for all your hard work!

Yeah seem to have the same issue here, cant run it with init.lua , using Fedora Silverblue:

health#mkdp#check

  - OK: Using pre build

I am using paq.nvim on my init.lua

require "paq" {
    "savq/paq-nvim";                  -- Let Paq manage itself
   {"iamcco/markdown-preview.nvim", opt=true ,run=vim.fn["mkdp#util#install()"] ,as="markdownPreview"}  ;   -- Markdown Preview
}

vim.cmd([[
augroup markdown!
    autocmd!
    au FileType markdown packadd! markdownPreview
    au FileType markdown setlocal spell spelllang=pt_pt,en_us
    au FileType markdown inoremap <C-l> <c-g>u<Esc>[s1z=`]a<c-g>u

    au FileType markdown set conceallevel=2
    augroup END
]])

@augustebaum @motorto ran into this issue today. Solved it by running this for the run hook:

require "paq" {
  'savq/paq-nvim';
  { 'iamcco/markdown-preview.nvim', run = function() vim.fn['mkdp#util#install']() end };
}

Any updates on this? I tried @logan-connolly solution, but didn't work..
