How to properly initialize plugins with new vim 8 packages feature?

Question

I'm using denite plugin and I have some intialization for it.

call denite#custom#source(
    \ 'file_rec', 'matchers', ['matcher_fuzzy', 'matcher_project_files'])
call denite#custom#var('file_rec/git', 'command', ['git', 'ls-files', '-co', '--exclude-standard'])

Since I moved from external package manager into vim packages I moved this into a function that is executed inside VimEnter autocmd. But now I want to open denite prompt when no files have been passed to vim as arguments.

au VimEnter * if argc() == 0 | exe ":Denite `finddir('.git', ';') != '' ? 'file_rec/git' : 'file_rec'`"

Which is quite easy, but the problem is that at this point vim still doesn't know anything about my custom 'file_rec/git' command.

I've tried to place initialization into ~/.vim/after/plugin/denite.vim, but that doesn't help. Vim is saying that he basically doesn't know what denite is at this point.

:help startup describes what Vim does on startup. I won't repeat the full details here, but you're correct that packages are loaded right after the initialization files (vimrc etc.) However, you can use the :packloadall to do this earlier if desired.

That being said, the VimEnter autocmd is run as the last step, and packages should have been loaded at this point, so that should work. Your autocommand does look funky though:

au VimEnter * if argc() == 0 | exe ":Denite `finddir('.git', ';') != '' ? 'file_rec/git' : 'file_rec'`"

• Why is there no endif? That seems like an error.
• What are those `s? Are you sure that's correct?
