I have a file template which is rendered with replacing some stubs when new file created:

augroup templates
  autocmd!
  autocmd BufNewFile *.java $r ~/.vim/templates/skeleton.java|call s:SetupJavaClass()

  fun! s:SetupJavaClass()
    exe "%s/__CLASS_NAME__/" . expand('%:t:r')
  endfun
augroup END

it's working fine, but only if I create new file with new buffer, e.g. vim Foo.java works, but when I create new file from NerdTree, new file is opening in current buffer and my templates and vim doesn't call my autocommands. How can I fix it? Is it possible to create autocommand to be executed on every new file, doesn't matter it was opened in new buffer or not, or maybe I should use ftplugin for that?

  • How do you create a new file from NerdTree? I don't have much experience with NerdTree, and I only saw commands to open existing files.

  • @JürgenKrämer I'm opening menu with m, then a to add new file, then I type filename, it creates a file which I'm opening in current buffet with o key.

  • The (a)dd a childnode menu item will ultimately result in a call to writefile([], a:fullpath) inside nerdtree/lib/nerdtree/path.vim. I don't think there is an autocommand that is triggered by writefile(). You might want to ask the maintainer of NerdTree if he/she could provide a hook for reading a template file.

As suggested @PhilRunninger in Github ticket, I can use BufRead autocommand and apply templates if file size is zero:

autocmd BufRead *.java if getfsize(expand('%'))==0|$r ~/.vim/templates/skeleton.java|call s:SetupJavaClass()|endif

it's working fine.
